3、導(dǎo)輪主軸驅(qū)動用交流電機經(jīng)變頻實現(xiàn)無極調(diào)速
4、機床主進給由伺服電機經(jīng)滾珠絲桿螺母副帶動導(dǎo)輪架進給與補償
5、電氣采用三菱控制系統(tǒng)（用戶）。
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.
