Generally, due to the installation adjustment, the feed dynamics between the axis are not adjusted according to the error, or due to the use of wear, the various transmission chains of the machine tool have changed (such as the gap of the silk bar, the change of the screw distance, the axial movement, etc. To. It can be resolved by re -adjustment and modified gap compensation.

When the dynamic tracking error is too large and the alarm is alarm, it can be checked: whether the speed of the servo motor is too high; whether the location detection element is good; whether the position feedback cable connects the plug -in well; Is the corresponding servo driver normal?

2. Instead of processing accuracy caused by super adjustment during machine tools

It may be that the increase and deceleration time are too short, and the speed change time can be appropriately extended; it may also be the loosening or rigidity between the connection between the servo motor and the screw, which can be appropriately reduced to the position of the position ring.

Third, the roundness of the two axes during machine processing is super poor

1. Round axial deformation

This deformation may be caused by the unreasonable mechanical adjustment. The positioning accuracy of the shaft is not good, or improperly compensation for the screw gap will lead to a circular error in the quadrant time

2. Candid ellipse error (ellipse on the direction of 45 degrees)

At this time, the position deviation of the axis should be checked first. If the deviation is too large, you can adjust the position of the position ring to eliminate it. Then check whether the interface board of the rotating drive or the sensor synchronizer is adjusted, and then check whether the mechanical transmission sub -gap is too large and the gap compensation is appropriate.
