臺(tái)式車床BB25-500/700
BB25型臺(tái)式車床,具有結(jié)構(gòu)布局合理,加工精度好操作方便、靈活、安裝簡(jiǎn)單,容易維修等優(yōu)點(diǎn)。它可以安裝在堅(jiān)固的木制或鐵制的臺(tái)板上。
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)。
