Products Description
- 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.
