Abstract
Ferrite material to be used in millimeter wavelength apparatus is sawed ug a resin bonded diamond sawblade. A cutting speed of 5400 cm/sec is achieved by appropriate selection of sawblade diameter and spindle speed, such as 5.71 cm and 18,000 RPM. With this cutting speed and sawblade material a cut up to a maximum of 0.356 cm is possible while the ferrite is fed at from 0.0254 to 0.127 cm/sec.
Claims7
A method of precision cutting of millimeter wave ferrite material comprising:
- securing said ferrite material on a platform capable of controlled lateral movement;
- and
- moving said platform at a controlled feed rate of from 0.0254 to 0.127 cm/sec relative to a rotating transversely positioned circular saw;
- said circular saw having a diameter and a spindle speed which combine to yield a cutting speed of 5400 cm/sec and having a blade fabricated of resin bonded diamond material.

Apparatus for precision cutting of millimeter wave ferrite material comprising:
- a circular saw blade;
- a rotatable spindle for vertically mounting said circular saw blade;
- motor means for rotating said spindle and said saw blade to provide a cutting speed of 5400 cm/sec.;
- a horizontally positioned platform for securing the ferrite material to be cut thereon;
- and
- motor drive means for moving said platform and ferrite material laterally at a controlled feed rate of from 0.0254 to 0.127 cm/sec across the path of said saw blade, said saw blade being fabricated of a resin bonded diamond material.
