Product Description

MW1350B Large universal cylindrical grinding machine

Main Applications and structural features
MW1350B cylindrical grinder is designed for grinding cylindrical or tapered surface of rotational parts. It is highly adaptable for single and small batch production.
The table longitudinal movement 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.
Grinding wheel of φ750x75xφ305 is used for high-efficient heavy grinding with rapid speed and high accuracy.
Work piece, wheel, hydraulic pump,coolant pump,are driven separetely by their individual motors.
Each motion part of the grinder is controlled by electric,hydraulic,mechanical interlocking mechanisms,thus the grinder can be operated with ease and safety.
