What is CNC Machining?
⇒CNC machining, or Computer Numerical Control machining, is a highly versatile manufacturing process that utilizes automated, high-speed cutting tools to precisely remove material from a workpiece—typically metal or plastic—until the desired shape and dimensions are achieved.
⇒Common types of CNC equipment include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. These machines operate in various ways: some move the tool while the workpiece remains stationary, others rotate and move the workpiece while the tool stays fixed, and some models move both the tool and workpiece simultaneously.
⇒The process begins when machinists receive a CAD (computer-aided design) model, often referred to as a 3D file. Using this model, they program the tool paths required to produce the part. An experienced machinist optimizes these paths to improve accuracy, maintain tight tolerances, and reduce overall CNC machining costs.
⇒CNC machines are capable of cutting a wide range of materials, including metal alloys, plastics, wood, stone, ceramics, and more. This flexibility makes CNC machining essential for producing custom parts across industries such as automotive, robotics, medical devices, aerospace, electronics, and industrial equipment.
⇒At 3ERP, we offer professional CNC machining services and provide custom quotes for a variety of materials—from standard options like aluminum, steel, stainless steel, ABS, and acetal, to advanced metals such as titanium and Inconel, as well as high-performance engineered plastics including Teflon, PPS, PEI, and PEEK.
