臺(tái)式車床BB25-500/700
| ||||||||||||||
| 該車床具有縱向機(jī)動(dòng)進(jìn)給機(jī)構(gòu)，采用掛輪系，交換齒輪可得到兩種機(jī)動(dòng)縱向進(jìn)給量，用于車削內(nèi)外圓柱表面，圓錐表面。利用上述機(jī)構(gòu)交換齒輪和使用開合螺母能加工常用的公英制模數(shù)螺紋。主軸端有4號(hào)莫氏錐孔，軸端法蘭安裝連接卡盤，尾座滑套具有莫氏2號(hào)錐孔，可安裝鉸刀、鉆夾頭、絲錐、板牙等*進(jìn)行攻絲、鉆孔、鉸孔、拉油槽等操作。 車削時(shí)，機(jī)床的主軸轉(zhuǎn)動(dòng)是由裝在床身背后的電機(jī)通過皮帶驅(qū)動(dòng)全齒輪主軸箱，按照變速操作手柄位置板動(dòng)手柄，主軸可得到六種轉(zhuǎn)速。范圍為115-1620rpm,利用開關(guān)使電機(jī)反轉(zhuǎn)，主軸可得到六種反轉(zhuǎn)速度。因此本機(jī)床具有較齊全的車削加工功能，性能良好。 本機(jī)床適用于小型機(jī)械修配、加工，特別適用于家庭、科研實(shí)驗(yàn)室及教學(xué). | ||||||||||||||
