1. Model M1450B universal cylindrical grinder is an improved version, renovated in design and structure from the basic Model M1450A, operated dunder the control of electric and hydraulic systems or by manual intervention. It is suitable for grinding extemal and internal cylindrical or conical surfaces of rotational parts in single-kind, and small batch production.
2. The table longitudinal traverse is actuated hydraulically at infinitely variable speed or operated by hands. The rapid approach and withdrawl, the intermittent micro infeed of the wheelhead are also effected by hydraulicmeans. In addition, the latter can by manually operated in corarse or fine infeed mode. All the above power funtions are accomplished by push-buttons, electrical and hydraulic control.
3. The structure of workhead spindle employs a rolling and a sliding bearing with their clearance adjustable. It is suitable for various grinding between centers or on chucks. The workhead canbe swivelled counterclockwise with in 90° . And by swiveling either the wokhead or work table or wheelhead, the external and internal surfaces of workpiece with different taper can be ground.
4. The worktable and wheelhead guideways are hydrostatically lubricated. The grinding whell spindle runs in a pair of partial journal bearings, each of which consists of three tilting segmental shoes. The internal grinding attachment bracket on the wheelhead can be turned down for grinding internal parts and multi-sets of extension bars are attached for option.
5. Workpiece, external and internal grinding wheels, hydraulic pump and coolant pump are all driven separately by their individual motors.
6. Each motion part of the grinder is controlled by electric and hydraulic interlocking mechanism. The external and internal wheel covers are strong and reliable, thus the grinder can be operated with ease and safety.
