Cylindrical crankshaft grinder
CR-Grind
The heavy-duty model Cylindrical crankshaft grinder with massive stiffened machine bed, allows accurate results with excellent grinding, even with heavy components. The aerostatic spindle and tailstock ensures minimal operating vibration even for long workpieces. An automatic lubrication system is included with all models. As is infinitely adjustable feed rate with hydraulic drive. The automatic “soft stop” significantly reduces the stresses on all components and allows for long term operation.
Available table sizes include 21×64″, 27×84″x 27×100″, and 31×119″. All models include longitudinal feed rate of 190″/min for the electric motor and 2.5-117″/min with the hydraulic drive. The setting per scale is 0.0025 mm. The longitudinal feed is 0.17″/rev.
