Left and right chucks are crisscross and adjustable . Workpiece is held by centers or by chucks driven by warhead motor, and fed by hand for grinding The machine is controlled by mechanical , electric and hydraulic means; operated mainly by hand. The worktable consists of upper and lower parts, and the upper part having the inclined worktable-surface at 10 degree. Longitudinal worktable travel is realized by manual-drive or motor-drive, with the motor-drive for jump displacement or adjustment. Max. adjustable amount of left and right chucks is 110mm in vertical direction. Workpiece , wheel, worktable , coolant pump and oil pump are driven by their individual motors. Worktable and wheelhead have the hydraulic and electric interlocking mechanism, ensuring the safety even if misoperation whether in sdjustment or in the process grinding. The wheelhead is equipped with the reliable protective guard. The coolant guard and the bed ways guard is stainless steel. The wheel balancing stand adopt new static wheel balancing stand .
