CNC Machinery

CNC stands for Computer Numerical Control; it is used in machinery to offer precision results without faults. A computer plots out how the machine cuts or turns the material, it basically gives out instructions in turn driving the machinery.

There are many different types of CNC Machinery available, often very expensive and large in size they are essential for the manufacture of parts and stored in workshops, often in large warehouses.

Below are some of the CNC Machinery available:

Metal Cutting Machines

These are one of the most common types and like the name states are designed to cut metal however some of these cutting machines are also capable of painting metal. They are very intrate machines and require a professional engineer to operate them.

Drilling Tapping and Boring

These machines are often stated as either Drilling, Tapping or Boring systems however the majority of them are capable of doing all 3 process. These can vary in size depending on the type of industrial project they are used for.

CNC Lathes

These units come as smaller units or Heavy Duty units, all of the equipment I am writing about are Computer Numerical Controlled. Lathes were designed to machine metal, however over the years they have adapted the technology to also machine plastics along with other materials.

CNC Milling

Milling machines are also used for painting and cutting of materials into products, they can also be used to grind certain materials.

A lot of companies offer CNC Machinery, they are designed for industrial use and not domestic, even some home workshop machinery can be acquired.

Buying CNC Plasma Cutters

CNC Plasma Cutters use a computer and a special coding language called G-code to program projects. The cutter then carries out the cuts you desire. This type of machine can increase your productivity by 1000% or more. So, what are you waiting for? Oh right! You want to know what to look for when you are buying one.

Recent improvements in technology and manufacturing have created an excellent buying environment. Plasma cutters are cheaper than they ever were and they are also more advanced than ever before.
First, you will want to be familiar with the plasma cutting process, since this will help you understand the different ways to classify plasma cutters. If you know your way around a plasma cutter already, feel free to skip the next paragraph.

In order for plasma cutting to work, plasma has to be created. Inside a plasma cutting torch, plasma is created by firing an electric spark into the torch nozzle while pressurized gas (often air) surges out of the nozzle onto the metal to be cut. The spark heats the gas to 15,000 degrees Celsius at which point the gas turns into plasma. Plasma is the fourth state of matter; it is both a liquid and a gas at the same time (this is analogous to how visible light is a wave and a particle at the same time). The electrical spark is created when the plasma cutting torch is touched to the cutting surface. This closes an electric circuit between the plasma cutting machine and the work piece.

Automated plasma cutting machines come in two flavors: conventional and precision. These classifications are based on the properties of the cutting flame. Conventional plasma cutting systems are slower than precision systems and they produce more kerf (the volume of metal cut out) and bevel. Being the superior system, precision plasma cutting equipment costs considerably more.

Buyer beware, manufacturers often mismatch power sources and machines. The machines come in two parts: the base machine (with the table, computer terminal and bridge or gantry) and the plasma cutter (precision or conventional). The power sources for those two components are separate and they have to be matched properly. The mismatches are often the manufacturer's fault, but you the buyer have to keep your eyes open to make sure that it does not happen. In the event that you do have mismatched hardware, do not start running it because what will ruin the machines. Contact the company where you bought the equipment and figure out a solution to the problem.

Today's automated plasma cutter market is dominated by two different models of machine, bridge style and gantry style machines. And the machines are generally made from two types of metal, steel (fabricated) or aluminum (extruded). The extruded aluminum machines are "light duty" and they are found in the realm of the artist and the hobbyist. They are best for doing limited amounts of cutting on thinner metals. The industry-strength machines are the ones made from fabricated steel; they can cut continuously all day as well as devour thick metals.

You will want to decide what sort of drive system you need for your projects. If you are a hobbyist or artist, using a conventional machine, a single-side drive system should be all you need. You may also consider a single-motor, dual-side drive system. The higher level drives increase precision which is not what conventional plasma cutters are built for so you would be throwing your money away if you bought higher-level drives. A precision plasma project will require a dual-side two-motor drive system to reach optimum performance.

You will have to think about what size of motor and gear box you require. If the mass of the motor and gear box are too small compared to the mass of the machine then the motor will not be able to effectively change the direction of cutting. This is important when the cuts go back and forth at high speeds. If the masses are not matched properly it will lead to unimpressive cut results and increase wear on the machinery, which may lead to premature failure.

5 Reasons Why You Should Look for CNC Machine Shops to Perform CNC Milling Operations

Most manufacturers – small and large scale ones; have been continuously providing end products to consumers which involves series of processes including producing and assembling of different components. Due to high product demands, manufacturers have to minimize their product turnaround time in order to supply sufficient products to their distributors or directly to their consumers. The most common method is to outsource specific tasks to specific companies.

When it comes to producing certain components involving CNC milling operations – most manufacturers or businesses would opt for CNC Machine shops. Similarly if your business requires parts production – here are a few reasons that you should start looking for CNC machine shops to perform such task:

Reason #1: Reduce overhead cost of your business operations – You can save much in parts production cost as you do not need to purchase any CNC milling machines. As these machines require maintenance over a long period of time, you do not need to pay any maintenance fees when the parts production tasks are performed by reputable CNC machine shops.

Besides that, you can save cost in hiring and training machine operators on a regular basis, as these shops have specialists who are in charge of supervising the work of their machine operators.

Reason #2: Have professional expertise to work on your prototype – Normally, a reputable CNC machine shop perform CNC milling operations based your prototype or designs. For instance, if you have a prototype or a design in form of CAD design, they will provide a consultation service which you will be directed to their engineers who are responsible to give professional advice about your design, as to ensure that the customized parts production is workable based on your preferences.

Reason #3: Perform repetitive cutting and drilling operations precisely – If you are in dire need of these specific components to be produced on a regularly basis, these CNC machine shops usually perform parts production tasks by using high precise CNC milling machines. In addition, these machines are capable to produce components in a large scale without neglecting accuracy and precision. Apart than that, you can possibly rely on these shops to carry out complex parts production as they provide CAD/CAM machining for 3D complex components.

Reason # 4: Able to reduce unwanted wastage – If your business has lack of production tools that could not machine high precision parts, you would likely to bear high production cost due to unnecessary wastage. As mentioned early, most CNC machine shops operate high precision CNC milling machines – for instance, a shop that is investing in Hurco machine tools, which are widely known in manufacturing complex parts precisely, can reduce wastage effectively.

Reason #5: Most shops provide additional precision machining services – In order to provide more CNC solutions to clients, most shops provide additional services like CNC turning, spark erosion as well as additional treatments like hardening, plating, anodizing and powder coating – which are offered with affordable rates. Therefore, you can request for a quotation from these CNC machine shops if you are interested in some of their additional services.

Based on the reasons above, hope that you will start looking for a reputable CNC machine shops that can boost productivity and profitability.

The Basics of CNC Machine Tools

To most of us, CNC sounds foreign, but equipment belonging to the CNC category are a daily thing for those related to manufacturing and fabrication industries. CNC stands for Computer Numerical Control which has been used since the 1970's at the sunset of computers. That is how it got its name, except that it was first called only NC or numerical control when it was first introduced.

The CNC is programmed to reduce manual intervention in a certain fabrication process, thus reducing production time and waste, thereby resulting to increased production efficiency. To illustrate this, metal preparation using conventional tools would require the operator to manually bore hole on the metal using a drill press. But before he can do it, he has to secure the metal in place, select the desired speed for rotation of the drill press, activate the spindle and manually drive the drill into the metal. That takes a lot of steps and errors and accidents are bound to happen at each step of the process.

The CNC machine simplifies all these work for the operator. With the CNC equivalent of the drill press, he only has to position the metal in its place, activate the spindle, set the controls and the machine does the rest. It is very well like the automated ways of doing things. Everything that an operator is required to do with the conventional machine tools is programmable with CNC machines.

Another advantage of a CNC machine is being able to produce consistent and accurate work pieces. Once the programming controls had been set, the CNC machine can produce thousands of identical pieces in a short span of time. This is almost impossible if done manually.

CNC machines are also flexible since processes are programmed. You can run a specific program for one piece, save it and recall it again the next time that piece is to be reproduced. These machines are also easy to set-up, so, allowing you to meet your deadlines faster.

All CNC machines have motion control, whether linear or rotary. This is one of the things that they have in common. The path or direction that the machine follows is called axis. The more axes the machine has, the more complex it is.

Common industrial examples of CNC tools are welders, drills, grinders, routers and lathes. But it is noteworthy to know that even home tools that belong to the CNC category. These are electronic paper cutters, quilting and embroidery machines and yes, your computer printer which operates on the X axis only.

Without us knowing it, some tools that we encounter as we do about our respectable businesses may be CNC machines too. The use of these machines is not only exclusive to the metal industry but in large range endeavors as well, especially those that require mass production of articles. As the demand increases, the need for producers to meet these demands becomes more urgent as well. But thanks to CNC machines, production processes are made easier, faster and safer.

CNC Router Machine

The CNC router machine cuts in three directions at once. The precision of the router's cutting relationships on the design software, software that provides a two-fold advantage to the router operator.

To begin with, the CAD software gives the operator of the CNC router machine the ability to create the design that will be cut into the solid plate.

After the operator creates the design, that same operator relies on the computer to send the proper operating instructions. The instructions from the software send signals to the router motor drive. These signals, termed tool path files, allow the motor controls to direct the precise motion of the router drive system.

The router bits perform the cutting of the CNC router machine. These bits are similar to drill bits. As mentioned above, the cutting can proceed along three different axes simultaneously. The CNC controls cause the movements of the drill bits to take place in small and precise increments.

The cutting along the x-axis moves from front to back. The cutting along the y-axis moves from left to right. The cutting along the z-axis moves up and down. The ability of the CNC router machine to move in 3 directions at once leads to the creation of interesting patterns and shapes.

The use of a CNC router machine guarantees savings in time and money. The CNC router machine produces each of its elaborately shaped products in a very small amount of time. In addition, the CNC router machine eliminates the need for an employee to stand at the router. A computer controls the operation of the router. Either the computer linked to the router can stand adjacent to the manufacturing devices, or it can sit at the desktop of the operator.

In other words, the operator of the CNC router machine can sit at his or her desk and direct the movement of the device that holds the router bits. The operator keeps control of this device, a machine part that is called a gantry.

The benefits of a CNC router machine increase steadily, spurred in large part by the increasing need for the manufacture of prototypes. Prototypes are test versions of a product. The creation of prototypes provides the manufacturer with a way to detect those places where an error in production could occur.

The precision of the router allows the operator to detect the scale of any possible manufacturing error. The computer can inspect a prototype and then alert the operator to the precise degree of expected changes in the routed product. The benefits of this precision are magnified by the potential for offline simulation of manufacturing processes. Without access to such precision, the manufacturer would not be able to use the creation of prototypes by the CNC router machine. Thanks to the precision of the router, the manufacturer can use the prototype to plan the needed strategy for an efficient full-scale production.

The CNC router machine enables manufacturers to utilize the latest technologies in order to achieve their business needs more effectively.

CNC Router Machine: Making Use of Computer Aided Design

CNC or Computer Numerically Controlled devices can be used for working with plastics, aluminum, steel, composites, wood, and foam. A router is a specific type of CNC tool which is available with many configurations. They may be smaller for home workshops or designed to meet the needs of manufacturing facilities. Each machine includes a CNC controller, at least one spindle motor, a table, and AC inverters. Typical formats are either three or five axis. A CNC router machine utilizes computer supplied coordinates to create accurate pieces. One software program is used to create the actual design while another sends the required specifications to the machine. They may be controlled by manual programming or directly. Most users rely on the CAD / CAM software to receive each machines full potential.

Used Woodworking Equipment: Reducing the Cost of Innovative Tools

A router makes it easier to perform repetitive jobs and supplies consistent output. Each completed process meets exact measurements thus improving industrial productivity. Improved precision reduces the amount of waste as well as errors typically experienced when these processes are done manually. They also cut down the time required to finish each piece. A CNC is capable of performing multiple carpentry functions including that of the panel saw and boring machine. These devices provide additional flexibility both in design and finished products. Many industrial businesses utilize CNC equipment to obtain the mentioned benefits. Woodworking is another very common use for them. Used woodworking equipment makes this equipment affordable to smaller businesses and hobbyist who might otherwise have to do without this beneficial tool.

It can be difficult to get the entire concept of this equipment unless it has been personally used. A router can be compared to a computer printer. Designs are created on the computer. They are then sent to the router to create a hard copy which is a three dimensional representation of what needs to be done. Machine tools create the desired end product instead of printer ink. An X, Y, Z coordinate scheme is used to perform multi-dynamic motion control. They are amazing devices for hobbyists, prototyping, production settings, and development of products. Purchasing these devices as used woodworking equipment makes it easier for a business to remain in budget and receive the many benefits of having them available. Reduced pricing allows individuals to utilize them as well.

Measurements are input or uploaded to the equipment. The router sets up to meet the input specifications. Cutting bits may have to be changed out depending on what is desired. The wood is positioned on a work table and a vacuum pump keeps it in position during cutting or boring. Design characteristics for a particular piece are sent to the machine before actual operation. These specifications provide measurements used during the process. Completion takes minimal time while supplying a perfectly cut or shaped piece. A woodworking CNC router machine can be purchased from a second hand seller. These companies sell used equipment at a more affordable price to both individuals and businesses. Consignment sales are another great way to obtain affordable machinery.

CNC Router Machines: Frequently Asked Questions

Computer numerical control (CNC) machinery was invented in the early 1970s. Since that time, it has redefined the way woodworkers use a router, a milling machine and other types of equipment. Machines that feature CNC technology offer several benefits over standard woodworking machines:

  • Greater cutting accuracy
  • Improved production rate
  • Reduction of human error

If you are considering buying a CNC router, but need some answers before you do, the answers below can help:

When should standard routers be replaced with CNC routers?

The need to replace standard routers with CNC routers could be demonstrated by several things, particularly:

  • The inability of standard routers to meet increased production demand
  • The need to produce intricate woodwork
  • The need to increase cost savings by reducing waste pieces

In addition to cutting more accurately than standard routers, computer controlled routers also cut with greater speed. For woodworkers who have a high production rate, the speed of a computer-controlled router can be as valuable as its accuracy.

How expensive is the average CNC router?

The cost of a CNC router depends on two factors: machine grade (e.g. hobby grade, mid grade, or industrial grade) and machine design (e.g. table size, number of cutter heads, type of vacuum, etc.). With these things in mind, the average cost of a hobby grade router is usually under $5,000; the average cost of a mid grade router is usually under $15,000; and the average cost of a well equipped industrial grade router is usually over $20,000.

Because the price of CNC routers can vary widely based on the factors above, the best way to receive a reliable estimate is to consult a professional seller of woodworking machinery.

Is it sensible to buy a router used?

Because industrial grade CNC routers are expensive and have a long lifespan, many woodworkers consider buying them used. As with buying any used machine, the quality of the purchase depends on the integrity of the seller. When the right steps are taken to confirm the integrity of the seller and the condition of the machine, buying an industrial router used is a sensible choice.

What type of training is necessary to operate a CNC router?

To operate a CNC machine, a woodworker must train to use the software program that controls it. The training regimen for most router machines consists of a mixture of computer based training and first person training. Most trainees can learn to operate the machine within weeks, and master its operation within months. In comparison, mastering the use of a manual router can take years.

Conclusion

Since their invention in the early 1970s, CNC router machines have changed the performance of wood routing. Today, they are the optimal choice for woodworkers who experience a high production demand, must produce intricate pieces, and/or need to cut costs by reducing waste pieces. To learn more about buying a new or used CNC machine, consult with a seller of new and used woodworking machinery.

All You Need To Know About CNC Lathe Machines

Now, there are multiple types of CNC machining process. All of them have different functionalities and operations; CNC turning uses a helix path to cut through the material, while CNC milling uses rotary cutters to remove excess material. All of them require specific machining tools that enable the workpiece to work do the desired work. CNC lathe is one such important tool. In fact, the lathe is seen as the pioneer for being the machine for metal cutting.

Sounds interesting, right? Let’s delve deep into the functioning, properties, and types of CNC lathe machine.

Introduction

A lathe machine is typically used for shaping the material into the desired form by removing the excess material from a given workpiece (generally cylindrical). Apart from serving as cutting and facing machine, a lathe is also used to perform complex operations such as knurling, deformation, metal spinning, woodturning, thermal spraying, metalworking and more.

According to machine historians, the manual lathe was first used by the reformers in the Ancient Egypt and Greece. The European nation widely utilized two-person lathe variety, with the former turning the workpiece (wood) and the latter cutting off the excess material with a single point cutting tool. With the Industrial Revolution came the modern lathe; advanced, fast, and better!

Main Parts of a CNC Lathe Machine

Before moving on to the functioning of a lathe machine, let’s quickly go through the primary components of a lathe machine:

1. Bed: As the name suggests, the bed of a lathe serves as the base of the whole machine where the different components are mounted. Generally heavily rigid in structure, the lathe beds are made from a 9:1 combination melting of toughened cast iron (semi-steel) and steel scrap. This method helps lathe bed to perform a sliding action easily.

While single-bed lathe machines are quite popular, we also get two-three pieced beds, pieces bolted together to meet the desired length. The beds have a high damping capacity to absorb the vibrations produced by the working machine.

2. Carriage: Used for mounting and moving the cutting tools, a carriage moves the tool horizontally and vertically on the bed for a smooth cutting process.

3. Chuck: A chuck is responsible for holding the workpiece. This component is attached to the spindle that rotates both the chuck and workpiece.

4. CNC Control Panel: The storage center of the machine, CNC control panel stores all the CNC programs and instructions. The CNC expert operates the machine by controlling the keys on the panel, instructing the machine to produce the desired results.

5. Headstock: This part functions as a holding device for the other components of the lathe like gear chain, spindle, driving pulley and more.

6. Main Spindle: The main feeding center of the machine. A stock is fed via the headstock.

7. Main Drive Motor: The drive motor helps rotate the chuck, thus driving the entire machine.

8. Tailstock: A tailstock is usually used to conduct drilling operations and support the system.

9. Tool Turret: A tool turret is used a tool carrier for the machine. The shape and the size of the turret are determined by the number of tools that’ll be mounted on them.

CNC Lathe Machine: How Does It Work?

As discussed in the last part, a typical lathe comprises of a bed, headstock, tailstock, chuck, tool turret, carriage and a spindle for feeding purposes. The following steps define how this particular machine works:

1. First Step: After checking the machine for the working faults, a cylindrical workpiece is attached to the chuck. Its position can differ as per requirement.

2. Second Step: We now set the spindle on the desired speed, thus rotating the chuck and the workpiece. Major attention needs to be paid on the spindle speed as any discrepancy can cause cutting errors. Check if the workpiece is turning properly.

3. Third Step: Now locate the cutting tool at the desired feed by moving the tool turret and carriage. Pay special attention to feeding speed.

4. Fourth Step: Remove all the excess metal by moving the carriage to get the finished product.

Types of Lathe Machines:

Just like every other machine, a lathe machine also has different varieties that are used to fulfill different work requirements. Let’s have a look at the major types of the CNC lathe machine:

Engine Lathes

Pretty popular amongst manufacturers, an engine lathe perfectly suitable for low-power operations. But that doesn’t mean that it cannot be used for high-power operations. This device is very reliable and versatile, operating on a wide range of speed & feed ratios. This type is perfect for manufacturers looking for a machine that works with different metals.

Centre Lathe

Centre lathe is a lathe type where the spindle speed is managed via a set of gears that are operated by using a lever.

Gap Bed Lathe

This type of lathe machine contains a removable bed section to accommodate the larger diameter of a workpiece, hence the name gap bed lathe. Generally, the part next to the headstock is removable.

Speed Lathes

A simpler version of a lathe machine, the speed lathe only has a headstock, tailstock, and tool turret. This type is generally used for light machine work as it can only operate in three or four speeds.

Bench Lathe

Smaller in size, a bench lathe can be mounted on a workbench for conducted lighter jobs.

Tool Room Lathes

This type is known for providing the best finishing. Tool-room lathe is highly versatile, working in a number of speeds and feeds.

Turret Lathes

A turret lathe is ideal for quick and sequential workings. With the tool holder in the vicinity, performing multiple operations on a single workpiece becomes several folds easier.

Special Purpose Lathes

These special purpose lathes are used to perform a heavy-duty production of identical parts. Some of the popular special purpose lathes include automatic lathes, crankshaft lathes, bench-type jewelers’ lathes, duplicating lathes, and multi-spindle lathes.

What Is A DNC System And Types Of CNC Machines

Once this system is developed, it must certainly be loaded into the CNC control. Although the setup person could type this system right into the control, this might be like using the CNC machine as a very costly typewriter. If the CNC program is developed with the aid of a CAM system, then it has already been in the form of a text file. If this system is written manually, it may be typed into any computer employing a common word processor (though most companies make use of a special CNC text editor because of this purpose). In any event, this system is in the form of a text file that can be transferred right into the CNC machine. A distributive numerical control (DNC) system is employed for this purpose.

A DNC system is only a PC that’s networked with one or more CNC machines. Until only recently, rather crude serial communications protocol (RS-232c) needed to be employed for transferring programs. Newer controls do have more current communications capabilities and may be networked in more conventional ways (Ethernet, etc.). Aside from methods, the CNC program must obviously be loaded into the CNC machine before it may be run.

Types of CNC machines

As mentioned, CNC has touched virtually every facet of manufacturing. Many machining processes have been improved and enhanced through the use of CNC. Let’s look at some of the specific fields and place the focus on the manufacturing processes enhanced by CNC machine usage.

In the metal removal industry:

Machining processes that have traditionally been done on conventional machine tools which can be possible (and sometimes improved) with CNC machining centres include a myriad of milling (face milling, contour milling, slot milling, etc.), drilling, tapping, reaming, boring, and counter boring.

In similar fashion, a myriad of turning operations like facing, boring, turning, grooving, knurling, and threading are done on CNC turning centres.

You will find a myriad of special “off-shoots” of these two machine types including CNC milling machines, CNC drill and tap centres, and CNC lathes.

Grinding operations of all types like outside diameter (OD) grinding and internal diameter (ID) grinding are also being done on CNC grinders. CNC has even opened a brand new technology as it pertains to grinding. Contour grinding (grinding a contour in a similar fashion to turning), which was previously infeasible as a result of technology constraints is currently possible (almost commonplace) with CNC grinders.

In the metal fabrication industry:

In manufacturing terms, fabrication commonly identifies operations which can be performed on relatively thin plates. Consider a steel filing cabinet. All the primary components are made of steel sheets. These sheets are sheared to size, holes are punched in appropriate places, and the sheets are bent (formed) to their final shapes. Again, operations commonly called fabrication operations include shearing, flame or plasma cutting, punching, laser cutting, forming, and welding. Truly, CNC is heavily involved in virtually every facet of fabrication.

CNC back gauges are commonly used with shearing machines to control the length of the plate being sheared. CNC lasers and CNC plasma cutters are also used to create plates to their final shapes. CNC turret punch presses holds a variety of punch-and-die combinations and punch holes in most shapes and sizes through plates. CNC press brakes are used to bend the plates within their final shapes.

In the electrical discharge machining industry:

Electrical discharge machining (EDM) is the procedure of removing metal through the use of electrical sparks which burn away the metal. CNC EDM comes in two forms, vertical EDM and Wire EDM. Vertical EDM requires the use of an electrode (commonly machined on a CNC machining centre) that’s of the form of the cavity to be machined into the task piece. Picture the form of a plastic bottle that must definitely be machined in to a mold. Wire EDM is commonly used to create punch and die combinations for dies sets found in the fabrication industry. EDM is among the lesser known CNC operations because it is so closely related to making tooling used with other manufacturing processes.

In the woodworking industry

As in the metal removal industry, CNC machines are heavily found in woodworking shops. Operations include routing (similar to milling) and drilling. Many woodworking machining centers are available that can hold several tools and perform several operations on the workpiece being machined. communications protocol.

Other forms of CNC machines

Many types of lettering and engraving systems use CNC technology. Waterjet machining runs on the high pressure water jet stream to cut through plates of material. CNC is even found in the manufacturing of many electrical components. For example, there are CNC coil winders, and CNC terminal location and soldering machines.
