How to prevent dimensional deviations in C-axis linkage machining?

Adjustment methods for preventing dimensional deviations in C-axis linkage machining

1.adjust the GO speed parameter ‌

Reduce the rapid positioning speed (G00) to minimize mechanical shock and avoid position errors caused by inertia.

Optimize the acceleration and deceleration time constants to ensure smooth movement and prevent out-of-step phenomena caused by sudden changes in acceleration ‌

2. Fix the lead screw problem ‌

Check the lead screw clearance. If it exceeds 0.15mm, it needs to be corrected through nut adjustment or system compensation function ‌

Straighten the deformed lead screw to ensure that its natural state is not affected by tangential force

3. Check and correct the program ‌

Check whether the program size is consistent with the drawing requirements to avoid programming errors ‌

Use programming techniques (such as backlash compensation) to eliminate deviations that cannot be adjusted by parameters ‌

Other key measures

 Tool and process optimization ‌ : Select the appropriate tool material to avoid incorrect clamping; Adjust the cutting parameters (such as spindle speed and feed rate) ‌ according to the material

Mechanical maintenance ‌ : Regularly check the runout of the main shaft and the coaxiality of the tailstock to ensure the machine tool is level and stable ‌

System monitoring ‌ : Observe the phase light of the driver to check for out-of-step or insufficient power issues ‌
