The poor machining accuracy of batch parts is generally due to the fact that the feed dynamics between each axis is not adjusted according to the error during installation and adjustment, or the transmission chain of each axis of the machine tool has changed after use and wear. It can be solved by readjusting and modifying the clearance compensation amount.

 

When the machine tool moves, the overshoot causes poor machining accuracy. ​cnc machining manufacturers ,It may be that the acceleration and deceleration time is too short, and the speed change time can be appropriately extended. It may also be that the connection between the servo motor and the lead screw is loose or the rigidity is too poor, and the gain of the position loop can be appropriately reduced.

 

Axial deformation of the circle: This deformation may be caused by a poorly adjusted machine. The positioning accuracy of the axis is not good, or the compensation of the lead screw gap is improper, which will lead to roundness errors when passing through the quadrant.

 

Oblique ellipse error: At this time, the position deviation value of each axis should be checked first. Then check whether the interface board of the resolver or the induction synchronizer is adjusted properly, and then check whether the gap of the mechanical transmission pair is too large and whether the gap compensation is appropriate.
