Adopting internationally advanced design concepts, the casting is made of high-standard wear-resistant cast iron and undergoes secondary aging treatment. The guide rail surface is precision ground by an imported guide rail grinding machine after medium-frequency quenching. The gear system is optimized with profile modification for four-speed stepless variable speed constant linear cutting, resulting in good machining accuracy, high rigidity, and strong vibration resistance.

The TP series CNC turning and polishing composite machine tool is a series of CNC turning and polishing composite machine tools developed by Jingjia Equipment based on customer needs, specifically designed for the precise and efficient processing of large heavy shaft parts.
