In the CNC machining center, the workpiece clamping method should pay attention to those aspects.

When determining the positioning reference and clamping scheme, the following 5 points should be noted:

1. The clamping device must not affect the feeding, and the processing part should be open.

2, must ensure the minimum clamping deformation, to ensure the accuracy of parts.

3, convenient loading and unloading, auxiliary time is as short as possible, when there are conditions, parts with larger batches should use pneumatic, hydraulic clamp or multi-station fixture.

4. For small parts or parts with short process time, consider processing several parts or dozens of parts at the same time on the workbench. To improve efficiency.

5, the fixture structure should be simple to reduce the cost of fixture manufacturing. When the parts are processed in small quantities, try to use combination fixtures, adjustable fixtures and other common fixtures; when the parts are produced in batches, special fixtures should be considered, but the cost can be reduced.
