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.

• 

  Setting-up System
  Integrated 4-way adjustment allows easy, accurate and fast operations. Variable 30° and 72° indexing. Dynamic balance ensured by reading the headstock manometer.

• 

  Bearings
  The double tapered SKF bearings in the head- and tailstocks are greased and sealed for life, ensuring trouble free operation for life.

   

• 

  Heavy-duty Set-up
  In-process measuring gauge, heavy-duty steady rest, extra counterweights and belt polisher. The complete heavy-duty set-up for the largest crankshafts.
