双头切割锯切削稳定性的影响与什么有关?

2018-05-07 点击数:298
1.型材强度、硬度高,消耗的功率增大,导热系数和热容小,散热能力降低。
1. the strength and hardness of the profiles are high, the power consumption is increased, the thermal conductivity and heat capacity are small, and the heat dissipation ability is reduced.
2.双头切割锯的切削速度影响,切削速度增加,消耗的功率增加70%-80%。工进吃刀量增加,切削功率成倍增加,但切削锯片热量也成倍增加。
2. the cutting speed of the double headed saw is the biggest, the cutting speed is increased, and the power consumption is increased by 70%-80%. The amount of cutting power increases, and the power of cutting increases exponentially, but the heat of cutting saw increases exponentially.
显然,从切削温度的角度出发,既要提高生产量,又使切削温度不过于升高,所以,选择切削用量的原则是:大的背吃刀量,较大的进给量,小的进给速度。

Obviously, from the angle of the cutting temperature, the production quantity should be increased and the cutting temperature is not too high. Therefore, the principle of choosing the cutting amount is the large amount of back knife, the larger feed and the small feed speed.

3.刀具参数前角增加,变形和摩擦减小,切削功率降低,产生的热量减小,切削温度下降,当前角再增大,由于契角减少,散热体积减小,切削稳定升高。竹片叫增大,切削刃工作长度减少,散热面积减小,切削稳定升高。
The front angle of 3. tool parameters increases, the deion and friction decrease, the cutting power decreases, the heat decreases, the cutting temperature decreases, the current angle is increased again, the cooling volume decreases and the cutting stability increases because of the reduction of the deed angle. With the increase of the bamboo slice, the working length of the cutting edge is reduced, the heat dissipation area is reduced, and the cutting stability is increased.
4 其他因素,使用切削液可带走热量,减小刀具磨损,防止切削刃变钝,导致变形和摩擦增大,使切削温度升高。
4 other factors, the use of cutting fluid can take away heat, reduce tool wear, prevent cutting edges from blunting, cause deion and friction increase, and raise cutting temperature.
