Types Of CNC Machine
CNC machines are automated motion control machines that consist of three components: a motion system, feedback system and a command function. The goal of CNC (Computer Numerical Control) is to make precise cuts of metal pieces for industrial use. There are several different kinds of CNC machines, though. If you are searching online for “types of cnc machine,” then this post is for you!
CNC Machine Types
Original numerical control machines date all the way back to the 1940s. Back then, using a motor was essential for other devices’ movement. While technology advanced, this helped the CNC machine lead the industry in a different direction earlier than expected. CNC machines were originally controlled by analog computers, and later, digital computers.
There is a whole line of CNC machines that are entirely electronic. Most commonly, CNC’s include some form of ultrasonic welding, laser etching, and hole crafting. Here is a list of the more common CNC machines being used today:
CNC Milling
CNC milling is a machining method that utilizes computerized controls and spinning multi-point cutting devices to remove material from a workpiece. This process will rapidly cut solid metal and plastics into smaller and final parts. Smooth finishes are possible, as well as producing 2D or 3D shapes. CNC milling machines can create parts for mechanisms, engines, enclosures and more. The end result will be custom-designed parts or products.
CNC Lathes
This particular machine rotates a piece through an axis of rotation (x and y respectively) to perform various processes. These tasks include cutting, knurling, sanding, drilling, deformations and turning. A CNC lathe is used to cut away any excess materials by rotating a piece on a spindle. Different drilling bills and cutters will chip away at the material(s). CNC lathes can be configured to cut precisely and efficiently. Such precise cuts would not be possible if done manually.
CNC Plasma Cutter
Plasma Etching is the elimination of silicon, plastic, or other non-metallic materials using plasma which is produced by exciting ions in a gas; typically oxygen and CF4. Those ions crash into the material at an atomic level and remove it without needing chemical acids. Within CNC plasma cutters, gas will be blown from a nozzle to the surface at very high speeds. Gas is then converted into plasma, with a temperature up to 50,000 degrees.
CNC Laser Cutter
CNC laser cutters are very similar to CNC plasma cutting machines. The biggest difference between the two, of course, is the use of the laser for cutting purposes. Lasers are tremendous tools used to cut metals, hardwoods and plastic materials. The intensity of the laser can be adjusted depending on the strength and density of the materials that needs to be cut.
Electric Discharging Machine (EDM)
Electrical discharge machines (EDM) use a nontraditional technique where material is removed from a workpiece via thermal energy. A lot like processes such as laser cutting, EDM doesn’t require mechanical pressure in the removal process.
The Two Different Sub Types Of EDM’s:
- In wire electrical discharge machines, a slim single-strand metal wire, is slipped across the piece. This wire will be submerged in a bath of dielectric fluid, generally deionized water.
- Electrical Discharge Machine or sinker EDM machining processes an electrically charged electrode calibrated to a particular configuration to burn the configuration of the electrode into a metal element. This type of process is usually used to produce molds and dies.
