CNC is a generic term used for a variety of machining techniques. “CNC” is a shorthand for Computer Numerical Controlled and refers to the ability to program the machine that allows the machine to perform a range of tasks with no human supervision. CNC machining is the process of making parts using an CNC controlled machine. The term describes a range of subtractive manufacturing techniques which involve the removal of materials from a workpiece that is stock or bar, in order to produce a finished component part. Five kinds of CNC machine are commonly used. They are performed with five different types of CNC machines. If you would like a full report about CNC machine, look at this website.
These processes are employed in many applications across a range of industries, including medical, aerospace oil and gas, industrial and hydraulics, firearms etc. A variety of materials can be CNC processed, including metals and plastics, glass, wood, and composites.
CNC machining offers many advantages over traditional machining which isn’t programmable. Significantly lower cycles, higher quality finishing and a variety of options can be accomplished simultaneously and improve the quality and reliability of. It is ideally suited to high and medium volume needs where accuracy and complexity are required.
CNC Lathes and Turning Machines
The ability to turn objects when machining is what differentiates CNC lathes and turning machines. The cutting tools for these machines are moved in a linear manner through the rotating bar stock by removing the material from the circumference until the desired size (and characteristic) is achieved.
One of the subsets of CNC Swiss lathes is the machine Pioneer Service uses. CNC Swiss lathes permit the material bar to spin and slide axially through the guide bushing that serves as a holding mechanism. This offers a greater amount of support for the material as the tooling machines the part has (resulting in better/tighter tolerances).
CNC lathes and turning machines are able to produce external and internal features on the component: drilled holes, bores, broaches, reamed holes slot, tapping threads, and tapers. The components made by CNC lathes and turning centers include shafts, screws, bolts, poppets, etc.
CNC Milling Machines
CNC milling machines are distinguished by their ability of rotating cutting tools while holding the workpiece or block stationary. They can produce a wide assortment of forms, including face milled features (shallow or flat surfaces as well as cavities within the workpiece) and peripheral milled features (deep cavities such as threads and slots).
CNC milling machines create parts in rectangular or square shapes with a range of options.
CNC Laser Machines
CNC laser machines feature an angled router that has laser beam that is highly focused that is utilized to precisely cut, make a cut or engrave objects. The laser’s energy is able to heat the material, causing it to melt or vaporize, resulting in an opening within the material. The material is typically laid out in sheets and the laser beam moves between the material, creating a precise cut.
This method can result in an array of designs than cutting machines that are conventional (lathes or turning centers, mills) and typically produce edges and cuts that do not require additional finishing procedures.
Part marking and the decoration of machined parts is a typical use of CNC laser engravers. As an example, it could be challenging to machine a logo and company name into the CNC milled or CNC turned component. However, laser engraving may be used to apply the logo to the part after the machining operations are complete.
CNC Electrical Discharge Machines
A CNC electric discharge machine (EDM) makes use of extremely controlled electrical sparks to manipulate materials into a desired shape. It can also be referred to as spark erosion, spark machining, spark sinking, wire melting, or burning wire.
CNC Plasma Cutting Machines
CNC plasma-cutting machines can also be utilized to cut material. They use a plasma torch (electronically-ionized gases) torch to cut the material. Similar in function to a handheld, gas-powered torch employed for welding (up to 10,000 degrees Fahrenheit) The plasma torch can achieve up to 50,000 degrees Fahrenheit. Plasma torch melts the piece to create a cut in it.
