High-Precision Lathe Processing: 

Catering to the unique processing characteristics of different products, the plant has designated areas equipped with specialized high-precision CNC lathes. 
This includes feed-type lathes, which have a stable and durable spindle collet. These lathes can accommodate slightly larger processing diameters and are suitable for cutting of small and medium-sized workpieces. 
Center lathes can produce high-precision small parts and are also suitable for processing long components.
Machine Type: TSUGAMI, CITIZEN, QINGQI
Part OD Limit: Min Ø5.0 mm ~ Max Ø32.0 mm
Part Length Limit: Min 0.5 mm ~ Max 300 mm
Tolerance: ±5~10 µm
Automatic Lathe Processing: 

The cam-type automatic lathes are high-performance and high-precision machines. The type is particularly suited for the processing and manufacturing of precision parts made from materials such as copper, aluminum, iron, and plastic. These lathes are ideal for batch production of small components used in various industries, including instrumentation, watch and clock, automotive, motorcycle, bicycle, eyewear, stationery, hardware, sanitary ware, electronics, plug-ins, computers, mobile devices, electromechanical products, and defence industries.
