机床的主要特点 Main Characteristics
• 机床的进给及修整，由二个互不干涉的传动机构执行，进给可采用手动或液动二种进给方式。
• 机床设有跳进、跳出机构，因此退出砂轮进行测量或修整后不必重新手动对刀。
• 工作台启动有液压开关阀，确保装卸和测量工件时的安全性。
• 机床在特殊订货，可配高速砂轮轴为18000转/分，以适宜20-50mm孔的磨削。
• MD2120A在床头箱顶部设有端磨装置，并且端磨回转与工作台纵向运动有可靠的液压连锁。
• The feed and dressing movement are controlled by two independent systems. Manual and hydraulic feed movement can be used.
• The machine is equipped with a jumping device, therefore,it is unnecessary to reset the machine after measuring or dressing.
• The table is equipped with a hydraulic switch valve to ensure safely during loading and unloading and unloading workpieces.
• The machine is provided with a grinding spindle of 18000rmin which is capable of grinding bore diameter ranging bore diameter ranging from 20 to 50mm
• An endface grinding device is provided on the top of the workhead.The is a hydraulic interlock system between the swivel of the endface grinding device and the longitudinal movement of the worktable.
