機(jī)床特點(diǎn)：

★本系列機(jī)床適用于中小型精密軸及盤類零件的圓柱、圓錐的外圓及內(nèi)圓面和端面的高精度磨削加工。

★機(jī)床工作臺(tái)、頭架、砂輪架等部件均能回轉(zhuǎn)一定角度。

★橫進(jìn)及床身導(dǎo)軌均采用減摩涂層技術(shù)，有效去除低速爬行現(xiàn)象，并且涂層有良好的吸震效果，大大提升磨削加工精度。

★頭架及砂輪架主軸采用整體大錐度成型油楔動(dòng)承結(jié)構(gòu)，具有回轉(zhuǎn)精度高，剛性大、溫升低的特點(diǎn)。

★尾架采用密珠套筒結(jié)構(gòu)，具有液壓伸縮功能，實(shí)現(xiàn)液壓進(jìn)退、彈簧夾緊。

★工作臺(tái)運(yùn)動(dòng)、砂輪架進(jìn)退既可液動(dòng)亦可手動(dòng)，并具有各種范圍工件切入半自動(dòng)定程磨削功能。
