根据切削原理及拉刀轮切道理,我们采用了一种新的切削方法。这种方法不打刀,效率高,切屑分配合理,切削平稳;不需特制刀具和夹具,简易方便,称双刀直进轮切法。具体调整方法如下: 以普通单线梯形螺纹螺距为6mm为例。在刀架上同时装二把刀。二把刀的刀体要磨成等高或垫至等高,这样能用一块宽压板把二把刀同时压紧。二把刀的刀尖须对准中心,其中心间距为一个螺距。一号 According to the cutting principle and broach round reasoning, we adopted a new cutting method. This method does not hit the knife, high efficiency, chip distribution is reasonable, stable cutting; no special tools and fixtures, easy and convenient, said double straight knife wheel cut method. Specific adjustments are as follows: Trapezoidal thread with a single trapezoidal thread 6mm, for example. Put two knives on the knife holder. Two knife body to be ground to contour or pad to contour, so that a wide plate can be used to compress the two knives at the same time. The knife tip of the two knives must be aligned to the center with a pitch of one center. One
