西安不銹鋼加工時(shí)主要的難點(diǎn)
一、加工時(shí)，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(shí)，做到刃口要鋒利，選擇合理角度。
二、轉速慢，切削時(shí)受力較大。生產(chǎn)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、鉆深孔及攻絲，難度*大。
五、加工不銹鋼，工人要有一定的經(jīng)驗和過(guò)硬的技術(shù)。
西安不銹鋼的加工性能：
1、不銹鋼切削時(shí)塑形大、韌性高，切削時(shí)消耗能量大，切削溫度高。不銹鋼導熱率低，散熱不好易形成刀具高溫;不銹鋼粘結凝焊性強，切削過(guò)程中易形成積屑瘤;不銹鋼加工硬化傾向強，切削表面易形成硬化層;不銹鋼不易斷屑，切削過(guò)程中易堵塞，影響加工表面的光潔。
2、不銹鋼切削刀具：前角，前角不易太大，一般取12--30°;前面，前面磨出月牙形導屑槽可改善切削條件;后角，對硬質(zhì)合金車(chē)刀，后角應為6--10°，對高速鋼車(chē)刀，后角應為8--12°;主偏角60--75°;副偏角，應為8--20°;在粗車(chē)時(shí)應大于零，在精車(chē)時(shí)應小于零;刀尖半徑，一般為0.2--0.8mm。
3、不銹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。
