· Hydraulically operated wheel slide movement
· Hydraulically operated face-plate locking pins
· Infinitely variable table traverse (U-machines)
· Hydraulically operated tailstock (U-machines)
· SKF double tapered roller bearings in head- and tailstock
· Antifriction non-stick coating underneath table
· Maintenance free hardened ballscrews and nuts
· Rapid backlash-free stroke setting
· Standard oil cooler on hydraulic power station

AMC-SCHOU crankshaft grinders are built to last with extra-strong castings to ensure stability and long life. All bearings are over-dimensioned to maximise reliability. Antifriction coating eliminates stick-slip effect. Fast and accurate setting-up is ensured by the face-plate system with integrated four-way adjustment. Variable 30° and 72° indexing with +/- 1° fine adjustment is standard. Maintenance free hardened ballscrews and nuts ensure backlash free stroke setting in seconds
– The Benefits of Precision.
