主要用途

本機(jī)床適用于幾何精度和表面質(zhì)量要求高的各種圓柱體零件、環(huán)形零件的無心通磨磨削，也適用于圓錐角不大于3°圓錐體零件和各種成型旋轉(zhuǎn)零件的無心切入磨削，尤其適用于大批量的生產(chǎn)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(jié)構(gòu)特點(diǎn)

1、砂輪主軸采用懸臂動壓軸承，導(dǎo)輪主軸采用滾動軸承雙支承結(jié)構(gòu)；

2、砂輪修整器進(jìn)給運(yùn)動由伺服電機(jī)驅(qū)動滾珠絲桿來實(shí)現(xiàn)，導(dǎo)輪修整器、手動進(jìn)給，砂、導(dǎo)輪修整器往復(fù)運(yùn)動均由油缸來實(shí)現(xiàn)

3、導(dǎo)輪主軸驅(qū)動用交流電機(jī)經(jīng)變頻實(shí)現(xiàn)無極調(diào)速

4、機(jī)床主進(jìn)給由伺服電機(jī)經(jīng)滾珠絲桿螺母副帶動導(dǎo)輪架進(jìn)給與補(bǔ)償

5、電氣采用三菱控制系統(tǒng)（用戶指定）。

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.
