How does a CNC machine works?

CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.

Advantages of CNC Machining

CNC machining stands for “computer numerical control” machining. It is a relatively new process in the world of machining which allows for increased efficiency through higher levels of automation and by allowing the machine and it’s computer controls to do all the work. While CNC machines are expensive and complicated, they quickly pay for themselves by reducing the workload and preventing errors. The first major advantage of CNC machining is that it improves automation, removing the need of an operator for all but a few parts of the work. CNC machines can be left unattended for hours or even days if necessary, allowing operators to focus on other tasks. This also allows for a company to retain fewer operators, thereby saving on overhead. By removing the operator, safety is also increased, since should there be a jam or other potentially dangerous machining error, the operator will not be holding the tool and the only thing damaged will be the tool itself. CNC machines can also work much faster than human machinists, since they are faster, stronger, and do not need to take breaks. They can also be run late at night, when most of the workers have gone home, since machines do not need to worry about being sleepy or getting paid overtime.

The second big advantage to CNC machining is that it produces an exact result every single time. Even the best human operator will have minor variations between finished results, whereas a CNC machine will produce exactly the same result each and every time it is run. This is very important in the modern world of standardized and interchangeable parts, where a single defective cut can make an entire machine wholly unusable. All that is necessary is for a single program to be developed and placed into the machine. Then the machine can toil away at however many work pieces are needed, producing an exact replica down to thousandths of an inch each and every time.

The third big advantage to CNC machining is the flexibility of the machine itself. While humans are much more flexible and trainable than machines, a CNC machine can be completely reprogrammed in a matter of hours to produce a completely different product. It is thus possible to refer back to old programs or install new programs when a different work piece is required. This gives CNC machines a big advantage over other machines, since they can quickly shift to producing a completely different product without the installation of many new parts or a major overhaul of key components. This also ensures that CNC machines can keep up with customer demand, since they can very quickly shift from making a part that is in surplus to a part that is lacking should a need arise.

CNC Turning

Our CNC turning process produces custom prototypes and end-use production parts in a very fast time, and we use a CNC lathe with tooling so feature like axial and radial holes, grooves and slots can be machined.

CNC Milling

Our CNC milling process produce custom prototypes and end-use production parts in a very fast time, and we use 3-axis milling and 5-axis milling machien processes to manufacture parts from many engineering-grade plastic and metals.

Wire Cut EDM

Wire Cut EDM, also known as (wire electrical discharge machining or wire EDM) is a method to cut conductive materials with a thin electrode that follows a programmed path. The electrode is a thin wire. Typical diameters range from .004" - .012" (.10mm - .30mm) although smaller and larger diameters are available. The hardness of the work piece material has no detrimental effect on the cutting speed. During the wire cut EDM process there is no direct contact between the wire and the work piece which allows for machining without causing any distortion. Rather, the wire is charged to a voltage very rapidly. This wire is surrounded by deionized water. When the voltage reaches the correct level, a spark jumps the gap and melts a small portion of the work piece. The deionized water cools and flushes away the small particles from the gap.

The CNC machine can independently move four machines axes to generate taper cuts. A stamping die can be machined with 1/4 degree taper or a mold with one degree taper in some areas and two degrees in another with precision. Extrusion dies can be cut with the taper constantly changing. For example, a detailed shape on the top of the work piece can transition to a simple circle on the bottom.

Wire cut electrical discharge machining is accurate to +/-.0001". Virtually no burrs are generated. Since no cutting forces are present, wire EDM is ideal for delicate parts. No tooling is required so delivery times are short. Pieces up to 16" thick can be machined. Tools and parts are machined after heat treatment, so dimensional accuracy is held and not affected by heat treat distortion.
