style="text-indent:25px">熱模鍛機床的滑動速度的因素在壓力一定的情況下，滑動速度小，形成潤滑油膜的作用就減小，油膜厚度較小，油膜常因承受不了運動件的壓力而部分破壞，造成兩金屬直接接觸，容易導(dǎo)致研傷。但滑動速度大到一定程度時，使摩擦副的溫度升高，易破壞潤滑油膜，也容易導(dǎo)致研傷，所以選擇合適的滑動速度可以降低產(chǎn)生粘著磨損型研傷的傾向。表面粗糙度的因素一般說來，摩擦副表面粗糙度越小，抗粘著磨損型研傷的能力就越大，適當(dāng)降低表面粗糙度可防止此類研傷。機床運行前應(yīng)校對機構(gòu)運動是否有足夠行程，調(diào)正并固定限位、定程擋鐵和換向碰塊等。</p><div
