該車床具有縱向機動進給機構，采用掛輪系，交換齒輪可得到兩種機動縱向進給量，用于車削內外圓柱表面，圓錐表面。利用上述機構交換齒輪和使用開合螺母能加工常用的公英制模數螺紋。主軸端有4號莫氏錐孔，軸端法蘭安裝連接卡盤，尾座滑套具有莫氏2號錐孔，可安裝鉸刀、鉆夾頭、絲錐、板牙等刀具進行攻絲、鉆孔、鉸孔、拉油槽等操作。
車削時，機床的主軸轉動是由裝在床身背后的電機通過皮帶驅動全齒輪主軸箱，按照變速操作手柄位置板動手柄，主軸可得到六種轉速。范圍為115-1620rpm,利用開關使電機反轉，主軸可得到六種反轉速度。因此本機床具有較齊全的車削加工功能，性能良好。
本機床適用于小型機械修配、加工，特別適用于家庭、科研實驗室及教學.
