在切削加工中,对于割刀要求它的刀头具有足够的强度,并易于使切屑从割槽中顺利排出,防止刀头脱焊。为了达到这个目的,我们根据不同加工条件,对割刀作了改进,如图3所示。刀片材料是T_(15)K_6,采用嵌焊式,使刀片焊接强度提高,克服了刀片脱焊现象。前角γ=17°,减少了切削力和摩擦热,从而提 In the cutting process, for the cutter requires its cutter head has sufficient strength, and easy to make chips from the cutting slot in the smooth discharge, to prevent bit off. In order to achieve this goal, according to the different processing conditions, the cutting knife has been improved, as shown in Figure 3. Blade material is T_ (15) K_6, using embedded welding, so that the blade welding strength, to overcome the blade off the phenomenon. Rake angle γ = 17 °, reducing the cutting force and friction heat, which mention
