CNC lathe

The car boring composite machine tool integrates the dual high-precision machining capabilities of CNC Lathes and Boring and milling machines. One device can simultaneously achieve precision turning, boring, milling, drilling, and tapping, avoiding precision loss caused by cross device transfer and secondary clamping of workpieces. The equipment is equipped with a high-precision rotary spindle and a precision power boring and milling head, with dual unit independent precision transmission. The turning and boring and milling processes can be freely switched, and the integrated disc shaft and small composite valve body can complete all precision machining processes in one clamping. The whole machine has a high rigidity integrated bed body with excellent seismic performance. The fully closed-loop grating system covers all motion axes, and the repeated positioning accuracy is stable at the micrometer level. The precision threads, deep boring inner holes, and flat milling dimensions are unified. Equipped with precision hydraulic fixtures and automatic tool magazine, with zero tool positioning offset, and optional feeding robot arm for unmanned precision mass production; The whole machine is equipped with a global constant temperature cooling system to suppress thermal deformation and ensure no fluctuation in machining accuracy throughout the day. Adapting to high-precision composite parts such as hydraulic composite valve bodies, precision gear shafts, and new energy special-shaped joints, one device covers multiple categories of precision machining needs, reducing equipment investment while significantly improving part size accuracy and finished product qualification rate.
