◆機(jī)床結(jié)構(gòu)采用砂輪架移動(dòng)式外圓磨床結(jié)構(gòu),工件只作旋轉(zhuǎn)運(yùn)動(dòng),砂輪架拖板(Z軸)在拖板床身上作縱向往復(fù)運(yùn)動(dòng),砂輪架(X軸)在拖板上作橫向進(jìn)給運(yùn)動(dòng),操作位置在拖板上的結(jié)構(gòu)布局。MCW1 380A系列外圓磨床床身結(jié)構(gòu)為工件床身與拖板床身鑄成一體,直徑800以上外圓磨床均采用工件床身和拖板床身分離結(jié)構(gòu)。

◆拖板縱向Z軸傳動(dòng)部分 為伺服電機(jī)驅(qū)動(dòng)齒輪齒條傳動(dòng),部分長(zhǎng)度5米以內(nèi)的數(shù)控型機(jī)床采用伺服電機(jī)驅(qū)動(dòng)滾珠絲杠傳動(dòng)。

◆砂輪架橫向X軸全部為伺服電機(jī)驅(qū)動(dòng)滾珠絲杠傳動(dòng)。

◆拖板縱向及砂輪架橫向?qū)к壘捎眯逗墒届o壓導(dǎo)軌,低速運(yùn)動(dòng)平穩(wěn)。

◆砂輪架主軸采用高剛性動(dòng)靜壓主軸,回轉(zhuǎn)精度高,剛性好,磨削質(zhì)量高。

◆頂磨型機(jī)床頭架及尾架主軸均為旋轉(zhuǎn)式活主軸結(jié)構(gòu),主軸采用超精密滾動(dòng)軸承支撐,稀油強(qiáng)力潤(rùn)滑,定位精度高,承載大。頂磨型機(jī)床的回轉(zhuǎn)精度*由頭、尾架主軸系選用的高精度軸承的精度保證,所以磨削質(zhì)量高。

◆頂磨型機(jī)床可選配四爪卡盤,可以實(shí)現(xiàn)一夾-頂?shù)姆绞竭M(jìn)行磨削。

◆MCW stands for PLC supporting grinding machine, MKW for CNC supporting grinding machine, MCD for PLC Center fixed grinding machine, MKD for CNC Center fixed grinding machine.Center fixed grinding machine can be used to grind heavy parts, easy to operate, high efficiency.

◆The structure of the machine adopts the structure of the wheelhead movable cylindrical grinding machine, the workpiece only makes rotating motion, the wheelhead dragging plate (Z axis) makes longitudinal reciprocating motion on the body of the dragging plate, the grinding wheelhead (X axis) makes transverse feeding motion on the dragging plate, and the operation position is arranged on the structure of the dragging plate.MCW1380A series cylindrical grinder bed structure for the workpiece bed and towed bed body cast into one, the diameter of 800 or more external grinder bed and towed bed body separation structure.

◆The spindle of the wheelhead adopts high rigidity static and static pressure spindle, which has high rotary precision, good rigidity and high grinding quality.

◆The headstock and tailstock spindles of the Center fixed grinding machine tool are all rotary living spindles, and the spindles are supported by ultra-precision roling bearings, with strong lubrication of thin oil, high positioning accuracy and large bearing capacity.
