結構特點
1、砂輪主軸(zhou)采用(yong)懸臂動壓軸(zhou)承(cheng)，導輪主軸(zhou)采用(yong)滾動軸(zhou)承(cheng)雙支承(cheng)結構；
2、砂(sha)(sha)輪(lun)(lun)修整器進給(gei)運動(dong)由伺(si)服(fu)電機驅動(dong)滾珠絲桿來實現(xian)，導(dao)輪(lun)(lun)修整器、手(shou)動(dong)進給(gei)，砂(sha)(sha)、導(dao)輪(lun)(lun)修整器往復運動(dong)均由油(you)缸來實現(xian)
3、導輪主軸驅動用交(jiao)流電機經變頻實(shi)現(xian)無極(ji)調(diao)速
4、機(ji)床主(zhu)進給由伺服電機(ji)經滾珠絲桿(gan)螺母副帶動導輪架進給與補(bu)償
5、電氣采用三菱控制系統（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.
