Description: |
| Claim:
A milling apparatus for milling a region of a workpiece, which is recessed below the principal surface of said workpiece comprising: a unitary tungsten carbide wheel adapted for rotation about a central axis of rotation; a lightweight motor to which said wheel is axially secured, said motor and said wheel being adapted for rotation of said wheel under load at rotational speeds providing a surface cutting speed for said wheel in excess of 2500 feet per minute, said wheel having opposing inner and outer radial surfaces and a peripheral surface with respect to said axis of rotation, said outer radial surface and said peripheral surface forming an included angle therebetween and having integrally formed cutting teeth thereon; and support fixture means adapted to hold said motor and wheel in a fixed vertical and angular position with respect to said principal surface, said fixture means being movable parallel to said principal surface and said fixture means having means for vertically and angularly adjusting said fixed position of said motor and wheel with respect to said principal surface, said outer radial surface and said peripheral surface of said wheel being angularly formed with respect to said axis of rotation so that said recessed portion of said workpiece may be ground thereby with said motor spaced substantially above said principal surface. |
