西安不鏽鋼加工時(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(duì)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(zhuǎn)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、鑽深孔及攻絲,難度*大。

五、加工不鏽鋼,工人要有一定的經(jīng)驗(yàn)和過硬的技術(shù)。

西安不鏽鋼的加工性能:

1、不鏽鋼切削時(shí)塑形大、韌性高,切削時(shí)消耗能量大,切削溫度高。不鏽鋼導(dǎo)熱率低,散熱不好易形成刀具高溫;不鏽鋼粘結(jié)凝焊性強(qiáng),切削過程中易形成積屑瘤;不鏽鋼加工硬化傾向強(qiáng),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(dǎo)屑槽可改善切削條件;後角,對(duì)硬質(zhì)合金車刀,後角應(yīng)為6--10°,對(duì)高速鋼車刀,後角應(yīng)為8--12°;主偏角60--75°;副偏角,應(yīng)為8--20°;在粗車時(shí)應(yīng)大於零,在精車時(shí)應(yīng)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(rùn)滑:采用冷卻潤(rùn)滑性能較好的潤(rùn)滑液,如硫化油、極壓乳化油、錠子油、油酸或植物油等。
