DEVICE FOR FINE FEED OF WORKPIECES AT GRINDING Russian patent published in 1997 - IPC

FIELD: mechanical engineering and instrumentation engineering for effective high-precision finishing of workpieces by grinding. SUBSTANCE: device has a base, upper plate with a workpiece chuck placed in parallel with the base. Heating element is also installed in parallel with the base, connected to the heating and cooling system and to the upper plate moving assembly. The latter is made in the form of four wedges located in pairs opposite each other on the upper plate and base. Balls are placed in two strips secured on the opposite ends of the heating element.
