Grinding and Lapping Machine. Using the Lapping Machine surfaces and edges can be reconstructed in a very special way: surfaces, edges, cuts and shapes of watch cases and metal straps can be exactly restored. Advantage against usual polishing motors: By repeated simple polishing of watch cases and bands, the edges and shapes are rounded more and more and the watch case looses its original shape/form. Only a precision lapping machine can reconstruct the original shape, especially edge grinding etc.
The LM-1 lapping machine has a powerful motor with electronic motor control board and speed control. As an extra an adjustable support table (Item No. 3963.1) can be fixed on the guide rail, (included in the basic equipment) or a watch case clamping device (3963.2)
