ABSTRACT:
A mandrel for use in an arc-jet spinning diamond deposition process for coating cutting tool inserts is disclosed. The mandrel has a plurality of cutouts or wells for receiving cutting tool inserts. The receiving wells are machined or otherwise provided to have the same contour as the cutting tool inserts that are placed in the wells. The receiving wells may all have an identical geometry, or different geometries. In one embodiment, the mandrel comprises a single element with the receiving wells machined into the upper surface of the mandrel. In another embodiment, the mandrel comprises a separate upper plate with the receiving wells cut through the plate to form a grid, and a lower base plate which is attached to the upper plate. An intermediate layer of a low melting metal foil may be placed between the grid and base plate to aid adhesion and to provide an interface of high thermal conductivity.
