數控軸承磨床作為軸承加工的現代化裝備，是軸承磨削加工向自動化和高效化和高精度化發展的重要設備。3MZ205D數控內圓軸承磨床是加工P4、P5級角接觸球軸承磨床內圈內徑的數控磨床。進給工作臺部件、往復工作臺部件為該數控磨床傳動系統重要的組成部分。其中，進給工作臺由滾珠絲杠、伺服電動機等組成，往復工作臺由油缸、活塞及往返機構系統組成。往復工作臺部件中工作臺的工作狀態只是直線往復運動，而進給工件臺部件為工件的進給系統核心，該部件的設計結構、安裝精度是軸承內圈內徑磨削后尺寸公差、形位公差是否合格的首要保證。

通過對3MZ205D數(shu)控軸承(cheng)內(nei)圓磨床進(jin)給工作(zuo)臺進(jin)行結構和工藝的(de)改進(jin)，降低了生(sheng)產(chan)費用(yong)，提高(gao)了生(sheng)產(chan)效率，增強了產(chan)品(pin)在市場的(de)競爭力，獲得了良好的(de)經(jing)濟和社會效益。
