What is CNC turning technology?

CNC turning technology is a turning processing technology based on computer control. It controls the movement of the machine tool through a computer program to achieve precision processing of metal or non-metallic materials. CNC turning machine tools usually include a rotating spindle, a movable tool holder and a workpiece clamping device. During the processing, the workpiece is fixed on the lathe and rotated by the spindle, while the tool cuts according to the preset path, thereby realizing the processing of various shapes and sizes.

Compared with traditional turning technology, CNC turning has significant advantages. CNC turning can achieve complex processing paths and precise dimensional control through programming, reducing the errors of manual operation. CNC turning can also realize automated production, improving production efficiency and consistency.
