Abstract
A cutting tool has a tool body and cutters metallurgically bonded to the tool body. The cutters are formed from laser to the tool body, with each cutter having a cutting edge formed thereon.
Claims21
The method of making a composite cutting tool comprising the steps of:
- a) providing a metal cutting tool body made from either low carbon steel alloy or low grade high speed steel alloy and having a mounting portion and a cutter portion defining a bonding surface;
- b) directing a light beam from a laser onto a portion of the bonding surface to melt metal at the bonding surface into a molten melt pool, flowing particles of high speed steel alloy into the molten melt pool and melting the particles in the melt pool, moving the light beam and melt pool along the bonding surface, solidifying the formerly molten metal in the melt pool after movement of the light beam to form a high speed steel laser cladding metallurgically bonded to the cutter portion at the bonding surface and having a height above the bonding surface;
- and
- c) abrading the cladding to form two surfaces intersecting at a cutting edge in the cladding.
