ZT 13E(EL)數(shù)控(大通孔)立臥回轉(zhuǎn)工作臺是各類銑床、數(shù)控鏜床和加工中心的重要附件。可分另以立式和水平式兩種方式安裝于主機(jī)工作臺上。工作時(shí)，利用主機(jī)的控制系統(tǒng)或?qū)ｉT的控制系統(tǒng)，完成與主機(jī)相協(xié)調(diào)和各種必須的分度回轉(zhuǎn)運(yùn)動。工作臺上除了可安裝板、盤或其他形狀較復(fù)雜的被加工零部件外，也可以利用主軸內(nèi)大直徑貫穿通孔安裝氣(液)動彈簧夾頭或動力卡盤，對長軸類零部件進(jìn)行加工，實(shí)現(xiàn)不等分、等分的連續(xù)的孔槽、曲直的加工，且達(dá)到較高的精度。
能夠自鎖 當(dāng)蝸桿的導(dǎo)程角小于齒輪間的當(dāng)量摩擦角時(shí)，若蝸桿為主動件，機(jī)構(gòu)將自鎖。這種蝸桿傳動常用于起重安裝中。
數(shù)控轉(zhuǎn)臺的傳動平穩(wěn) 蝸桿齒是連續(xù)的螺旋齒，與蝸輪的嚙合是連續(xù)的，因而，傳動平穩(wěn)，噪聲低。

ZT 13E( EL) NC rotary table with through hole in the spindle center is suitable for either horizontal or vertical position,it is a perfect accessory for NC miller and machine center.Used in combination with the control of NC
machine tool or an independent control for non-NC machine tool,continuous cutting work for board type,disk type,hole plate as well as other parts fixed between table and tailstock can be carried out precisely,especally with thethrough hole in the spindle center,hgdraulic(pneumatic )actuating coolect and chuck can be used to proceed long shaftype parts,
