西安不鏽鋼加工時主要的難點

一、加工時，刀具與工具的發(fā)熱量高，刀具易磨損，因此，對刀具要有一定的要求，要耐磨耐高溫。同時，做到刃口要鋒利，選擇合理角度。

二、轉速慢，切削時受力較大。生產效率不高。

三、發(fā)熱量高，冷卻油選擇很重要，一般用氯化硫。效果較好。

四、鑽深孔及攻絲，難度*大。

五、加工不鏽鋼，工人要有一定的經驗和過硬的技術。

西安不鏽鋼的加工性能：

1、不鏽鋼切削時塑形大、韌性高，切削時消耗能量大，切削溫度高。不鏽鋼導熱率低，散熱不好易形成刀具高溫;不鏽鋼粘結凝焊性強，切削過程中易形成積屑瘤;不鏽鋼加工硬化傾向強，切削表麵易形成硬化層;不鏽鋼不易斷屑，切削過程中易堵塞，影響加工表麵的光潔。

2、不鏽鋼切削刀具：前角，前角不易太大，一般取12--30°;前麵，前麵磨出月牙形導屑槽可改善切削條件;後角，對硬質合金車刀，後角應為6--10°，對高速鋼車刀，後角應為8--12°;主偏角60--75°;副偏角，應為8--20°;在粗車時應大於零，在精車時應小於零;刀尖半徑，一般為0.2--0.8mm。

3、不鏽鋼切削中的冷卻潤滑：采用冷卻潤滑性能較好的潤滑液，如硫化油、極壓乳化油、錠子油、油酸或植物油等。
