该厂根据缝纫机机壳的工艺特点设计了一台结构紧凑的机壳三面专用铣床。机床上配置着两个铣削头,这两个铣削头一前一后地布置在机床的左边。前铣削头上安装一把端铣刀,后铣削头上装两把三面刃铣刀,刀杆的最外悬伸处用支架支撑着。机床的主运动和进给运动由同一个电动机驱动。两个铣削头的主轴旋转运动是由电动机经减速器传出的。工作台的进给运动由主轴经过皮带轮、减速器和丝杠螺母传出。
The factory under the sewing machine shell features a compact design of the machine designed three-sided special milling machine. The machine is equipped with two milling heads, which are arranged one behind the other on the left side of the machine. Before the milling head to install an end mill, after the milling head mounted two three-sided cutter, the outermost cantilever bracket with a support. The main movement and feed movement of the machine are driven by the same motor. The rotation of the spindle of both milling heads is transmitted by the motor via a gear unit. Workbench feed movement from the spindle through the pulley, reducer and screw nut.
