STANKO Schleifmaschinen und Fräsmaschinen

STANKO - UNIVERSAL HIGH-PRECISION SEMI - AUTOMATIC CYLINDRICAL GRINDING MACHINE Model 3U12AF11

The semi - automatic machine is designed for grinding external and internal cylindrical, conical and face surfaces of workplaces positioned in centres, jaw chuck, face plate or collets. Machining of workpieces is effected by traverse or infeed grinding in a semi - automatic cycle controlled by a digital display (DD) or in-process control device (IPSCD), delivered on order, and also manually; IPSCD permits grinding the shaft to ensure a preset clearance (interference) in a pair with the mating part.
