Confirmation of reference point position when tool change is made
Mar 31, 2017

As the tool change point of the machine and the Z-axis reference point coincidence, the machine during the operation due to screw thermal expansion and other reasons, may cause a slight change in the relative position of moving parts, resulting in reference point drift, Deviation occurs.

To prevent this from happening, we have added "Z-axis tool change point confirmation switch" near the reference point position. This switch only works when the tool change is made. As long as the machine returns to the exact reference point position, Knife action can be carried out, otherwise, can not complete the tool change.
