Universal Cylindrical Grinder M1450B
Main Application and Features of FORTUNE M1450B Universal Cylindrical Grinder
1.FORTUNE M1450B Universal Cylindrical Grinder operated under the control of electric and hydraulic systems or by manual intervention. M1450B Universal Cylindrical Grinding machine is suitable for grinding external and internal cylindrical surfaces of rotational parts in angle piece or small batch production;
2.The M1450B Cylindrical Grinding Machine table traverse is actuated hydraulically at infinitely variable speed or operated by hand. The rapid approach, withdrawal and the periodic micro infeed of the wheelhead are also effected through hydraulic means, in addition the latter can be manually operated in coarse or fine infeed mode. All the above power functions are accomplished by pushing buttons or levels activating electrics or hydraulics;
3.The structure of M1450B Cylindrical Grinding Machine headstock spindle employs a rolling clearance. M1450B is suitable for grinding between centers or on chucks of various sizes. The M1450B headstock can be swiveled counter-clockwise within 90 degree and by swiveling either the headstock or worktable or wheelhead the external and internal surfaces of workpiece with different taper can be ground;
4.The M1450B worktable and wheelhead guideways of Cylindrical Grinding Machine are hydro-statically lubricated. The grinding wheel 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 the attachment is supplied with several sets of internal grinding quills;
5.Workpiece, external and internal grinding wheels, hydraulic pump and coolant pump all driven separately by M1450B Universal Cylindrical Grinder individual motors;
6.Each moving area in the FORTUNE Brand M1450B Cylindrical Grinder grinder is controlled by electric and hydraulic interlocking mechanism;
7.The external and internal wheel covers are strong and reliable, thus the grinder can be operated with ease and safety.
Working Accuracy of FORTUNE M1450B Universal Cylindrical Grinder
1.Roundness(outer circle/inner circle): 1.5-2.5/2.5μm;
2.Dia. Uniformity in the long Section: 8/15μm;
3.Surface roughness(outer circle/inner circle): Ra0.16μm/ Ra0.63μm.
