How CNC Milling Works?
CNC turning is a subtractive manufacturing process that utilizes computer-controlled lathes to shape materials into precise cylindrical parts. The process begins with designing the part using CAD software, which is then converted into machine instructions through CAM software. During setup, the appropriate cutting tools are installed, and the cylindrical workpiece is securely held in the machine’s chuck, which rotates the material for shaping.
As the machine operates, the workpiece spins at high speeds while the cutting tools move along various axes to carve, cut, and shape the material based on the programmed design. Common operations like facing, threading, knurling, and drilling are performed, often with coolant applied to prevent overheating and clear away debris. After machining, the part may undergo finishing processes such as sanding or polishing, followed by a thorough inspection to ensure it meets the required dimensions and tolerances.
