ABSTRACT:
A single-slide, mechanically and electrically programmed grinding machine comprising a rigid enclosed base, a fixed workhead assembly on the base, a pair of parallel slidebars mounted on the base, and a wheelslide assembly mounted on the base for longitudinal displacement thereover. Longitudinal wheelslide displacement is mechanically controlled by a motor-driven cam bearing against a spring-biased lever pivoted to the base and connected to the wheelslide via a rod. Lateral feed is independently electrically controlled by a motor-driven nut and screw shaft assembly which angularly displaces the wheelslide assembly relative to one of the slidebars and about the centerline of the other slidebar. An eccentric and variable-position spacer is provided for reciprocating the wheelslide during a grind operation. A thermally-stable base configuration is disclosed. Part load and unload apparatus, all mechanically programmed, are also disclosed.
