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.
