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.

Standard Equipment: Universal chucks, set-up indicator, steady rest, crank centering V-gauge, radius dresser, front & side dresser, wheel balancing arbour, grinding wheel and hub, lifting hook, coolant system, splash guards, set of tools and operating manual.

K-Machines

Extra Equipment for Engine Rebuilding Machines

AMC-SCHOU delivers a wide selection of extra equipment for the K-Machines. These expansions make the everyday use of the machine faster and thereby more profitable.

           Automatic Sizing Gauge
           Automatic sizing gauge allows continuous control when grinding (can be used with steady rest).

• 

  
  CE Safety Guards
  CE safety guards can be mounted on the head- and tailstock to offer protection against the rotating counterweights.

• 

  Throw-setting Device
  A factory mounted throw-setting device is a must for V-crankshafts.
