Diamond Tool

To increase the life of machining tools fitted with diamond tool plates, the monocrystalline diamond tool plate is made to engage the workpiece to be machined at a predetermined crystal orientation.

The drawing shows the nose of a diamond tool consisting of the end of a shank 1 with a diamond tool plate 2. Tool plate 2 and shank 1 have a common plane of symmetry parallel to the plane as drawn. Tool plate 2 comprises facets 3 on its front face, which are slightly inclined to true rake 4.

The <110> direction of tool plate 2, which points towards the workpiece, not shown, is inclined about 2 degrees to 10 degrees to the direction (arrow 6) of motion of the workpiece. In addition, this crystal direction lies within the tool's plane of symmetry in which, also pointing towards the workpiece, a <100> direction extends which is disposed at an angle of 90 degrees to the <110> direction. The relatively high-permissible angle tolerance of the <110> direction imposes no special accuracy requirements.
