機(jī)床的主要特點(diǎn) Main Characteristics
? 機(jī)床導(dǎo)軌采用雙V型預(yù)加負(fù)荷,高精度十字交叉滾柱滾動(dòng)導(dǎo)軌,精度高,剛性好。
? 機(jī)床采用高速大功率電動(dòng)砂輪軸,由靜止變頻器供電,能耗低,嗓音小。
? 進(jìn)給機(jī)構(gòu)采用三滾輪系統(tǒng)、液壓控制、精度高。
? MD215A機(jī)床帶有端磨裝置,一次裝夾可完成內(nèi)孔及端面磨削,工件端面與內(nèi)孔的垂直度。
? High precision preloaded dual-V cross rolling guideways are used to provide high accuracy good rigidity.
? Equipped with high speed and high power electric spindle powered by static frequency convertor,featuring low energy consumption and low noise.
? 3-roller system is used in feed mechanism which is controlled hyd raulically.thus providing high accuracy.
? Model MD215A Internal Grinders are also equipped with the endface grinding attachment, so that inner bore and endface grinding can be performed, thus guaranting perpendicula rity of work endface to bore.
