What is CNC turning?
CNC turning is a machining process based on computer numerical control technology, using equipment to perform high-precision cutting. Because it is computer-controlled, it allows for rapid and large-scale production, and through computer programming, it can perform even more complex precision machining. Currently, common parts such as shafts, bushings, and discs are mostly machined using CNC turning. It offers high machining accuracy, high automation, and good part consistency, making it suitable for mass production and one of the core processes in manufacturing.
the advantage of CNC turning machining
High Machining Precision
Numerical control programs ensure strict control of dimensional and geometric tolerances
01
High Degree of Automation
Automatic cutting and tool changing reduce manual labor intensity
02
High Production Efficiency
Optimized parameters and continuous operation greatly shorten processing cycles
03
Excellent Part Consistency
Parts processed with the same program have uniform dimensions and quality
04
Capability for Complex Machining
Programming enables the processing of complex structures such as threads and curved surfaces
05
