Application of GSK986 CNC System on the Eccentric Circle Grinding from Zhejiang Company

Customer Requirement:

Workpiece diameter: 12-15mm; Eccentric distance: 0.5-3.5mm;
The workpiece should be completed the grinding the clamping once;
The processing accuracy should be controlled within ±0.004mm; and the consistency of the batch production should be better;
It should be owned the automatic grinding wheel trimming and automatic compensation functions.

Troubleshooting:

To equip with the X/Z/C axes, and the axis C is regarded as the index axis, which is performed the follow-up grinding by using the G98 command;
Axis X is equipped with the high resolution grating ruler and guaranteed that the repeated positioning precision is consistent with the product.
Axis C is equipped with the round grating ruler; alternatively, it is used the servo motor with high resolution.

Application Effect:

The usage of this machine tool is free from the limitations based upon the fixture to perform the grinding before, instead of limiting the fixture to grind one kind of workpiece; it is solved the problems of instable processing accuracy due to that the workpiece is affected by the precision of the fixture.
This machine tool can be randomly select the eccentric distance based upon the demands of the customer’s orders. The sampling in new purchasing order is greatly improved than the traditional machine tools. (It is necessary to make the fixture first for the traditional machine tool).
The join of the grating ruler makes a great improvement of the repeated positioning precision of the machine tool, and the control of the product consistency is better.
