      雙頭切割鋸切削穩定性的影響與什么有關?

      2018-05-07 點擊數:1384
      1.型材強度、硬度高,消耗的功率增大,導熱系數和熱容小,散熱能力降低。
      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.雙頭切割鋸的切削速度影響,切削速度增加,消耗的功率增加70%-80%。工進吃刀量增加,切削功率成倍增加,但切削鋸片熱量也成倍增加。
      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.
      顯然,從切削溫度的角度出發,既要提高生產量,又使切削溫度不過于升高,所以,選擇切削用量的原則是:大的背吃刀量,較大的進給量,小的進給速度。

      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.刀具參數前角增加,變形和摩擦減小,切削功率降低,產生的熱量減小,切削溫度下降,當前角再增大,由于契角減少,散熱體積減小,切削穩定升高。竹片叫增大,切削刃工作長度減少,散熱面積減小,切削穩定升高。
      The front angle of 3. tool parameters increases, the deformation 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,使用切削液可帶走熱量,減小刀具磨損,防止切削刃變鈍,導致變形和摩擦增大,使切削溫度升高。
      4 other factors, the use of cutting fluid can take away heat, reduce tool wear, prevent cutting edges from blunting, cause deformation and friction increase, and raise cutting temperature.
