Types of CNC Services a Machining Business Offers / /
CNC milling produces parts without cylindrical features. During milling, the workpiece remains stationary while a cutter rotates around the piece. CNC milling can be used to create a finished product from raw material or as a secondary process to add definition. CNC milling can be used with various materials, including metals, glass, plastics, ceramics, elastomers, and composites.
CNC turning produces parts with cylindrical features. During CNC turning, the workpiece rotates at a high speed while a single point cutting tool subtracts material. CNC turning is primarily used on metal alloys.
Wire EDM is used to produce parts that require complex geometries and high accuracy. During Wire EDM, a tool discharges sparks that melt through the material, creating cuts. Throughout the process, the workpiece is submerged in water, which carries away any waste. EDM can be used on titanium, carbon steel, tungsten and other electrically conductive materials.
Waterjet machining is used to produce parts with outstanding edge quality. During water jet cutting, a pump with a cutting head as small as a human hair generates an extremely high-pressured stream of water. The water is combined with an abrasive (garnet) to cut through thick material such as steel. Materials used for waterjet cutting include aluminum, titanium, steel, Inconel, brass and composites.
Plasma cutting produces highly durable parts. During the plasma cutting process, material is shaped using a plasma torch. An electric arc forms between the cathode and workpiece or anode. The electrode is submersed in water or an air-cooled gas nozzle to constrict the arc and form the plasma jet. Plasma cutting is used with metals such as aluminum, copper and steel.
