YHDM750A/1高精度數(shù)控立式雙端面磨床主要特點(diǎn)：Technical characters：
1.采用三菱E70數(shù)控系統(tǒng)，性能穩(wěn)定可靠，人機(jī)界面友好。
2.零件加工中上、下兩平面同時(shí)分層次進(jìn)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(shí)現(xiàn)高精度磨削。
4.磨頭進(jìn)給采用高精密滾珠絲杠副(號:ZL200520050915.X)，進(jìn)給精度達(dá)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(jī)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2級過濾，冷卻機(jī)溫度控制后循環(huán)使用。
8.采用鉸鏈?zhǔn)綀A盤送料機(jī)構(gòu)（號:ZL200820052659.1），開啟靈活，更換和修整砂輪方便。
9.機(jī)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 interactive interface 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 scale value: 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..Filtered by magnetic and paper tape two steps, the coolant recycle after oil temperature controll er.
8.Adopt hinged carrier plate mechanism（Patent No:ZL200820052659.1）, which is easy to open to make a convenient change 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.
YHDM750A/1高精度數(shù)控立式雙端面磨床主要用途：Main purpose：
本機(jī)床可加工各種外形異形和圓形的金屬、非金屬薄型精密零件（軸承、閥片、密封件、油泵葉片、活塞環(huán)等）上、下兩平行端面的磨削。
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, seal, oil pump vane, piston ring, etc.
