Crankshaft Grinding Machine
                                   MQ3240 & MQ3260 & MQ3266

   Crankshaft grinding machine is suitable for grinding cranks of engine crankshaft in automotive, tractor and diesel repair shops, and also can
be used for general cylindrical grinding.
   Wheelhead cross rapid feed and table longitudinal movement all are driven by hydraulic.
   The machine tool set a safe interlock, when grinding crankshaft and wheelhead at grinding position, table can longitudinal move by only
manual, don't hydraulic driven; when wheelhead at back position, table can longitudinal move by manual and hydrarulic.
   The grinder can realize grinding external cylindrical, table longitudinal feed by hydraulic and feed speed variable; wheelhead manual feed.
   The workpiece is clamped by centers or chucks, driven by the headstock motor, and manually ground.
   Longitudinal movement of table adopts the methods of manual or hydraulic movement.
   Workhead spindle, wheelhead spindle, oil pump, cooling pump are driven by separate motors.
   The worktable and the grinding wheel adopt hydraulic and electric interlocking structure, which can ensure the operation safety regardless of adjustment or grinding due to operational errors.
   The wheelhead is equipped with a reliable protective cover.
