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 30o and 72o indexing with +/- 1o 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 30o and 72o 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. |
