武汉重型机床厂生产的Y31200A型立式滚齿机的加工直径为180～2000毫米、最大加工模数为24毫米、最大加工宽度为1200毫米,可用来加工直齿和斜齿的圆柱齿论、蜗轮、带空刀槽与不带空刀槽的人字齿轮。该机床还能加工轴齿轮,具有卧式滚齿机的性能。其加工精度高,主要是在结构上作了改进,主轴采用了静压轴承定心结构,其工艺范围也扩大了。因此,这台机床深受用户欢迎。
Y31200A vertical gear hobbing machine produced by Wuhan Heavy Machine Tool Plant has a processing diameter of 180-2000 mm, a maximum processing modulus of 24 mm and a maximum processing width of 1200 mm. It can be used to process cylindrical teeth of straight and helical teeth, worm gears, Herringbone gears with and without empty sipes. The machine can also process shaft gear, with horizontal hobbing machine performance. Its high precision machining, mainly made improvements in the structure, the spindle adopts a hydrostatic bearing centering structure, the scope of its technology has also been expanded. Therefore, this machine is very popular with users.
