Product Description

MW1463B Large Universal cylindrical grinding machine


Main applications and structural features
MW1463B large universal cylindrical grinder is designed for grinding cylindrical or tapered surface of rotational parts and internal grinding. It is highly adaptable for single and small batch production.
The table longitudinal traverse is actuated by hydraulic means at infinitely variable speed or operated by hand wheel.
Auto intermittent micro-infeed and rapid approach and withdrawal of the wheelhead can be effected hydraulically; while rough- & fine-feed realized by hand wheel.
The worktable and wheel head guideways are hydrostatically lubricated.
Internal grinding length arrive at least 800mm.
Work piece, grinding wheel, hydraulic pump, coolant pump, are driven separately by their individual motors.
Each motion part of the grinder is controlled by electric, hydraulic,mechanical interlocking mechanisms, and thus the grinder can be operated with ease and safety.
