本(ben)機床適用(yong)于幾(ji)何精度(du)和表面質(zhi)量要求高的(de)各種圓柱體(ti)零(ling)(ling)件、環(huan)形零(ling)(ling)件的(de)無(wu)心通磨(mo)磨(mo)削(xue)，也適用(yong)于圓錐角不大于3°圓錐體(ti)零(ling)(ling)件和各種成型旋(xuan)轉(zhuan)零(ling)(ling)件的(de)無(wu)心切入(ru)磨(mo)削(xue)，尤其適用(yong)于大批量的(de)生產要求。
Application
This machine can be used for through feed grinding of cylindrical and ring type parts with high accuracy and surface finish and also for plunge feed of taper parts with a taper smaller than 3°and formed parts.It can also be used for mass production.
結構特點
1、砂輪(lun)主軸(zhou)采用(yong)懸臂動壓軸(zhou)承，導輪(lun)主軸(zhou)采用(yong)滾動軸(zhou)承雙支承結(jie)構；
2、砂輪修(xiu)整器(qi)(qi)進(jin)給運動由(you)伺(si)服電機驅動滾珠絲桿來(lai)實現，導(dao)輪修(xiu)整器(qi)(qi)、手動進(jin)給，砂、導(dao)輪修(xiu)整器(qi)(qi)往復運動均由(you)油缸來(lai)實現
3、導輪主(zhu)軸(zhou)驅動(dong)用交流電機經變頻實現無極調速(su)
4、機床(chuang)主(zhu)進給由伺服電機經滾珠(zhu)絲桿螺母副(fu)帶動導輪架進給與補償
5、電氣(qi)采用三(san)菱(ling)控制系統(tong)（用戶指定(ding)）。
Main structural features
1.The grinding wheel spindle adopts the cantilever type dynamic bearing, while reg.wheel spindle is dually supported by the rolling bearing.
2.The servo motor drives the ball-screw to perform feed movement of gri.wheel dresser.Reciprocating Movement of regulating & grinding wheels and Manual feed are achieved by the oil cylinder
3.The erg.Wheel spindle is driven by a AC freq.Conversion motor to achieve a stepless speed-regulation.
4.Reg.Wheelhead feed & comp.is performed by a Servo motor through a ballscrew and nut pair.
5.Mitsubishi control system is adopted.
