A method of loading cutting tool inserts in a PVD (Physical Vapor Deposition) coating equipment consists in using a tube manufactured of a non-magnetic metallic material surrounding a stack of alternating discs of a magnetic material and iron. The north poles of the magnets are directed towards each other and the cutting inserts are positioned on the outer wall of the solid tube and kept in place by the magnetic forces.

Fixture and loading method for PVD coating of cutting tool inserts

There is provided a method of coating cutting tool inserts by CVD methods with a completely covering coating. During the coating step, the inserts are resting in contact with the support in only a few tiny spots and sufficient space is allowed around each insert to ascertain optimum coating conditions. In a preferred embodiment, each insert rests on a peg allowing a rational production in larger scale and fully automatic CVD loading.
