This precision screw adjustment sleeve is manufactured exclusively by CNC turn mill composite machining. It is a typical complex rotary component that cannot be finished by simple CNC turning. It integrates multi-step shaft body, complex internal spline, evenly distributed circumferential hollow slots and precision fitting holes, with high-precision fit tolerances strictly per customer drawing requirements.
CNC turn mill composite equipment completes outer turning, internal spline milling, slot cutting and hole machining all in one single clamping operation. It fully eliminates positioning deviation caused by repeated re-clamping, guarantees high accuracy for internal spline profile, slot position and mounting holes, and delivers reliable torque transmission and stable assembly performance.
It is suitable for automation equipment, packaging machinery, transmission assemblies, robotics and other custom OEM applications.
Final dimensions and tolerances are manufactured according to the approved customer drawing.
