YHDM7745雙端面數控立式高精度磨床主要用途： Main purpose
適用于對各種外形的金屬、非金屬薄形精密零件（軸承、閥片、密封件、油泵葉片、活塞環等）上下兩平行端面的同時磨削。
It is designed for simultaneously grinding the two parallel side surfaces of the workpiece. Various high precise and thin workpieces with parallel side surfaces, no matter made of metal or nonmetal material, can be processed. Such as bearing, valve, seal, oil pump vane, piston ring, etc.
YHDM7745雙端面數控立式高精度磨床技術特點： Technical characters：
1、機身采用整體結構，磨頭部件與床身緊密配合，上箱體整體調整結構；機床魔頭主軸立式配置。
2、采用西門子數控系統，性能穩定，智能化和靈活性強。
3.磨頭部件采用高精度進給機構，并配備了副蝸輪可隨時調整磨頭回程間隙，提高了整個磨頭的進給精度，磨頭部件密封可靠、潤滑充分，保證了機床長期高精度。
4.圓盤送料機構采用交流伺服電機，傳動平穩，轉速進給、恒磨除率加工（即每個零件的加工采用變速進給），提高了工件的加工質量和效率；傳動平穩，轉速1—15r/min；同時開啟靈活、更換砂輪便捷。
5、裝備CBN砂輪，實現其高速、高效、高質磨削。
6、采用馬波斯測量儀，實現了其在線跟蹤測量及反饋，使機床能從粗磨、半精磨到精磨的轉換。

8、采用機械手上下料，自動化強度高。
9、修砂輪采用金鋼滾輪等方式.
1.The machine body adopts boxlike overall structure; The grinding head parts and body section work closely together with overall adjustment structural for the upper machine body; with vertical wheel head spindle .
2.Adpots Siemens CNC system withstable performance, high inligentization and flexibility.
3.The wheel head parts adopt high precise feeding system and equipped with auxiliary worm wheel to adjust the return clearance of wheel head at any time, so that improve the feeding accuracy of the entire wheelhead , The grinding head parts are with reliable sealing and sufficient lubrication to get the guarantee of long - term precision.
4.Feeding carrier mechanism adopts AC servo motorwithStable transmission, rotational feeding (rotational speed 1-15rpm) and constant removal rate processing (that is variable speed feed processing to each workpiece),which greatly raise the quality and the efficiency of processing; Open is flexible, replacing wheel is convenience.
5.Equipped with CBN grinding wheels, High speed, high efficiency, high quality grinding
6.Marposs measurer with continuously measuring and feedback, make sure the transferring of rough grinding to fine grinding.
7.The cooling liquid can be recycled after the treatment through the magnetic scraper conveyor - vortex separator - oil cooler - pipe filters
8.Mechanical arm loading and unloading, high automation.
9.Diamond roller wheel of the dresser unit.
