YHDM750A数控立式高精度双面磨床主要用途：Main purpose：

本机床可加工各种外形异形和圆形的金属、非金属薄型零件（轴承、阀片、铝合金板、密封件、油泵叶片、活塞环等）上、下两平行端面的高效精密磨削。

It is designed for grinding the two parallel side surfaces of the various high precise and thin work pieces with round and abnormal shape, no matter made of metal or nonmetal material, can be processed. Such as bearing, valve plate, seal, oil pump vane, piston ring, etc.

YHDM750A数控立式高精度双面磨床主要特点：Technical characters：

1.采用三菱E70数控系统，性能稳定可靠，人机界面友好。

2.零件加工中上、下两平面同时分层次进行磨削，加工精度高，不须辅助定位（如磁盘）.

3.双端面磨削与砂轮修整控制程序(软件著作权:211R11S04392),实现高精度磨削。

4.磨头进给采用高精密滚珠丝杠副(号:ZL200520050915.X)，进给精度达0.001mm。

5.磨头电主轴采用变频调速驱动，转速150-950r/min。

6.送料盘送料电机采用变频调速器驱动，转速1-10r/min 。

7.冷却液经磁性分离、纸带过滤、沉淀过滤３级过滤，冷却机温度控制后循环使用。

8.采用铰链式圆盘送料机构（号:ZL200820052659.1），开启灵活，更换和修整砂轮方便。

9.机身采用箱形结构，上、下磨头立轴式配置，刚性和热稳定性可靠

1.CNC system chooses Mitsubishi E60 with friendly HMI and reliable performance.

2. The parts’ processing for the upper and lower surfaces is simultaneous with high precision, and without assisted positioning ( such as disks )

3.The program about the double disc grinding and wheel dressing control makes it to get high precision grinding.

4.Wheel head feed adopts precise ball screw unit. Feeding precision: 0.001 mm.

5.Wheel head spindle is driven by converter, 150-950r/min.

6.The motor of the feeding carrier adopts converter control; the speed is 1-10rpm.

7.The coolant is filtered by three steps including magnetic separation, paper tape filtering, sediment filtering two steps, cooling machine will be put into cycle use after temperature control.

8.Adopt hinged carrier plate mechanism（Patent No:ZL200820052659.1）, which is easy to open to make a convenient replacement and dressing of the grinding wheel..

9..The machine body adopts casting boxlike structure with good shock absorption and reliable rigidity and thermal stability; Wheel heads spindle are set by vertical configuration.
