When clamping workpiece on the CNC indexing plate, it is good to lock the indexing head spindle, but before each indexing, loosen the handle of the brake spindle, and then tighten it after indexing, in order to avoid loose spindle in milling. Indexing, the positioning bolt on the handle should be the hole, gradually inserted into the hole, can not suddenly let the bolt automatically spring into, otherwise, overnight, the hole will produce wear around, increase the error in indexing.
There should be a certain meshing gap between the worm gear and the worm in the NC dial. This gap adhere to the 0.02~0.04mm range. Too large clearance will affect the precision of indexing, too small clearance will increase the wear between worm and worm gear. In loading and unloading and handling, to maintain the spindle before and after the conical hole surface and the bottom plane, strictly prevent collision, and often smooth, avoid rust or debris.
The spindle of CNC indexing plate can not only be parallel to the workbench, but also make the spindle and the workbench vertical or into a certain Angle. When the rotary body needs to turn the Angle, it is necessary to loosen the fastening screw on the shell, and it is forbidden to knock under any circumstances. The side of the bottom positioning key is the positioning surface with high accuracy, pay attention to not damage, otherwise it will affect the positioning accuracy.
