Product Introduction
MG8260 series crankshaf are simple in construction, easy in operation and wide in application; suitable for grindingcrankshaft pins and joumals, lt can also be used as cylindrical grinder.The machine is controlled by mechanical, electric and hydraulic means; operated mainly by hand.Left right chucks are crisscross and adjustable.
Workpiece is held by centers or by chucks, driven by workhead motor, and feed by hand for grinding.The worktable consists of upper and lower parts, and upper part having the inclined worktable-surface at 10″( only for MQ8260B/6)Longitudinal worktable travel is realzed by manual-drive or motor-drive, with the motor dfive for jump displacement or adjustmentThe max. wheel, worktable, coolant pump and oll pump are driven by their individual motors.
Worktable and wheelhead have the hydraculic and electric interlocking mechanism, ensuring the safely even if misoperation whetheiin adlustment or in the process of grinding. The wheelhead is equipped with the reliable protective guard, the coolant guard and thebed ways guard is stainless steel. The wheel balancing stand adopt new static wheel balancing stand.
Features
1.The rapid advance and retreat of the grinding wheel frame is completed by hydraulic pressure.
2.The longitudinal movement of the workbench can be manual or mechanical. When it is mechanical, the workbench can only be moved in a jog and moved quickly to facilitate the grinding of the next journal.
3.The workpiece can be clamped by a three-jaw chuck, or the head and tail chucks can be removed and supported by the center.
Main Applications
MQ8260 is a crankshaft grinder suitable for grinding crankshaft necks and main journals of engines in automobile, tractor and diesel engine repair shops, and can also be used for grinding general external circl
