Work Holding, Foam Tape & Non-slip Material
Non skid Workholding and Workholders
Workholding is one of the most important factors when carrying out a lapping operation. The flatness of a part can be adversely affected by incorrect workholding.
For continuous lapping of the same range of parts, it makes sense to have sets of profiled workholders. A full range of blank workholders 3mm or 6mm thick are available. We can also supply pre-profiled workholders on request.

Kemet Facing Kit
The Kemet facing kit consists of a non-skid rubber pad. This pad can be fixed to the bottom surface of the hand weight to hold parts without a workholder and protect the parts being lapped. The hand weight with the pad is then placed directly on top of the parts which have been positioned inside the conditioning ring. Lapping can occur and the parts will not skid out of position.
On complicated parts, special workholding fixtures may be required. When producing such fixtures, the following points should be borne in mind:
1. The weight of the fixture should be balanced when holding the parts.
2. Ideally, three or more parts should be held in the fixture.
3. Often height setting blocks are helpful when assembling parts into the fixture.
4. When holding round or similar shapes where the end face is to be lapped, use a 'V' type location rather than a hole in a block.
5. The fixture should be a loose fit within the conditioning ring so it is free floating on the Lapping Plate.
