自去年增产节约开展后,高速切削多刀多刃在各厂普遍地推广,因此对机床的转数与动力都感觉得不够应用,尤其是皮带车床,它的转数与动力远远地落后于现实要求,但是它的数量所占比重,仍然很大(几占全部车床的80～90%),所以改装皮带车床,不但在经济上有它一定的价值,而且还具有一定 Since last year’s increase in production and saving, high-speed cutting multi-blade multi-blade in the general promotion of the factory, so the machine speed and power are not enough applications, especially the belt lathe, its number of revolutions and power lags far behind However, its quantity still accounts for a large proportion (accounting for 80-90% of the total lathes), so it is not only economically valuable but also certain
