YHDM750A數(shù)控立式高精度雙面磨床主要用途：Main purpose：
本機床可加工各種外形異形和圓形的金屬、非金屬薄型零件（軸承、閥片、鋁合金板、密封件、油泵葉片、活塞環(huán)等）上、下兩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數(shù)控立式高精度雙面磨床主要特點：Technical characters：
1.采用三菱E70數(shù)控系統(tǒng)，性能穩(wěn)定可靠，人機界面友好。
2.零件加工中上、下兩平面同時分層次進行磨削，加工精度高，不須輔助定位（如磁盤）.
3.雙端面磨削與砂輪修整控制程序(軟件著作權(quán):211R11S04392),實現(xiàn)高精度磨削。
4.磨頭進給采用高精密滾珠絲杠副(號:ZL200520050915.X)，進給精度達0.001mm。
5.磨頭電主軸采用變頻調(diào)速驅(qū)動，轉(zhuǎn)速150-950r/min。
6.送料盤送料電機采用變頻調(diào)速器驅(qū)動，轉(zhuǎn)速1-10r/min 。
7.冷卻液經(jīng)磁性分離、紙帶過濾、沉淀過濾３級過濾，冷卻機溫度控制后循環(huán)使用。
8.采用鉸鏈式圓盤送料機構(gòu)（號:ZL200820052659.1），開啟靈活，更換和修整砂輪方便。
9.機身采用箱形結(jié)構(gòu)，上、下磨頭立軸式配置，剛性和熱穩(wěn)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.
