Double Column Vertical Lathe Series

產(chǎn)品說明
本系列機床是一種*雙柱立式車床，機床具有兩個立刀架，可用于內(nèi)外柱面、圓錐面、切槽等粗、精加工。
結(jié)構(gòu)特點：
該立式車床由左、右立柱、頂梁、工作臺底座組成框架式結(jié)構(gòu)，剛性強，能承受較大的切削負(fù)荷。
橫梁沿立柱導(dǎo)軌上下移動，有碟形彈簧通進(jìn)杠桿夾緊在立柱上，橫梁升降的操縱按鈕在懸掛按鈕站上，橫梁上有微動機構(gòu)可調(diào)整衡量水平位置。
左、右兩個刀架裝在橫梁上，在橫梁上裝有供有供手動操作作刀架的手柄，以便于調(diào)整刀架的位置和對刀?；碇亓坑蓧毫τ瓦M(jìn)行平衡，在刀架滑座的上部裝有兩件卸荷滾子，擰動其上端的螺釘可調(diào)整卸荷滾子的承載能力，以便減輕手動操作時的用力。
工作臺有主電機經(jīng)變速箱直接啟動和制動。各級轉(zhuǎn)速由變速油缸推動交換齒輪實現(xiàn)十六種轉(zhuǎn)速的變換，轉(zhuǎn)速變換選擇開關(guān)在懸掛按鈕站上。
工作臺鑲有鋅鋁銅合金耐磨導(dǎo)軌板，并在導(dǎo)軌間通入壓力油（0.2～0.4Mpa）以提高導(dǎo)軌承載能力。工作臺主軸上裝有一個單向推力球軸承和一個雙列短圓柱滾子軸承，以保證主軸能在高精度下平穩(wěn)的工作。
橫梁左、右刀架上各裝有一個潤滑手壓泵，以便操作者方便地對它們進(jìn)行潤滑。
電氣控制可采用日本PLC編程控制器控制。
This machine is a kind of double-column vertical lathe, which is widely used in the field of metallurgical industry, chemical industry, power-generating equipment and national defense for machining process. It can be used for rough and fine turning of outer cylinder, inner hole, end surface and tapered surface of work-pieces.
1、  The machine frame is composed of right and left columns, head beam and table base, has strong stiffness, which can bear the load of cutting.
2、  The cross rail moves vertically along column guidways and it is clamped on the columns through the levers via disk springs. The vertical motion of the cross rail is controlled through the push buttons on the pushbutton station. There is a micro-adjusting device on the cross rail for adjusting level of the cross rail.
3、  There are left and right vertical tool posts on the cross rail. There are manually operated handles of tool carries on the cross rail for adjusting tool post position and for cutting tool setting. Turn the screw on top of the device, the bearing force of the roller can be adjusted for reducing manucal force when operation.
4、  The working table can be started and stopped directly by the main motor via gearbox. There are 16steps of table rotation speed; the speed can be selected by turning the switch on posh-button station.
5、  Casting alloy anti-abrasive plates are lined on the table surface. The oil is pressed between guidways with a 0.2-0.4Mpa pressure so as to raise the loading capacity of the guidways. A one-way thrust ball bearing and a double-row short cylindrical roller bearing are mounted on table spindle so as to ensure the high accuracy.
6、  On cross rail, left tool post and right post, there each has a manually operated oil pump for manul lubrication during working .
7、  The electric system is controlled by the Programmable Controller（PLC）which made by Japan.
