What is CNC Machining?
CNC (Computer Numerical Control) machining is a manufacturing process that utilizes computerized controls to operate and manipulate machine tools. It is widely used for creating precise, complex parts across various industries, including aerospace, automotive, and medical sectors.
How CNC Machining Works
CNC machining involves programming a computer to control machine tools like mills, lathes, and routers. The process follows these key steps:https://www.jtrmachine.com/
Design Creation – Engineers create a CAD (Computer-Aided Design) model of the desired part.
CAM Processing – The CAD file is converted into a CNC program using CAM (Computer-Aided Manufacturing) software.
Machine Setup – The appropriate material is loaded, and tools are prepared for the machining process.
Execution – The CNC machine follows programmed instructions to cut, drill, or shape the material with extreme accuracy.
Types of CNC Machines
Different types of CNC machines cater to various manufacturing needs:
CNC Milling Machines – Use rotating cutting tools to remove material.
CNC Lathes – Rotate the workpiece while cutting tools shape it.
CNC Routers – Ideal for cutting softer materials like wood, plastic, and foam.
CNC Plasma Cutters – Use a high-velocity plasma torch to cut metals.
CNC Laser Cutters – Employ lasers for high-precision cutting and engraving.
