機(jī)床采用T型布局形式,在立柱的導(dǎo)軌上裝有拖板,導(dǎo)軌中間位置裝有垂直進(jìn)給機(jī)構(gòu),傳動精度高，互換性好,在傳動過程中用十字接頭連接,可補(bǔ)償絲杠與減速器軸的中心誤差。工作臺移動采用閉式液壓系統(tǒng),前后進(jìn)給可手動進(jìn)給,液壓自動進(jìn)給或變頻電機(jī)帶動絲桿自動間歇進(jìn)給,磨頭上下移動為機(jī)動快速升降和手動進(jìn)給兩種方式。采用高強(qiáng)度鑄鐵基礎(chǔ)件,磨頭主軸采用筒子瓦或高剛性套筒結(jié)構(gòu),機(jī)床整體剛性強(qiáng),品質(zhì)穩(wěn)定,運(yùn)行平穩(wěn)。

The machine tool adopts the t-type layout form, the guide rail on the column is equipped with a drag plate, the middle position of the guide rail is equipped with a vertical feed mechanism, the transmission accuracy is high, the interchangeabil- ity is good, the cross joint is connected in the transmission process, can compensate the center error of the lead screw and the reducer shaft. Closed hydraulic system is adopted for the movement of the worktable. The front and rear feed can be manually fed, the hydraulic feed can be automatically fed, and the lead screw can be fed automatically intermittently driven by a variable frequency motor. Adopt high strength cast iron foundation, grinding head spindle adopt bobbin or high rigidi- ty sleeve structure, the machine overall rigidity is strong, the quality is stable, the operation is stable.
