西安不鏽鋼材料鑽孔時的注意事項

鑽削不鏽鋼材料時,經常發現鑽頭容易磨損、折斷,孔表麵粗糙,有時出現深溝而無法消除;孔徑過大,孔形不圓或向一邊傾斜等現象。因此,西安不鏽鋼加工提醒在操作時應注意下列事項:

1、幾何形狀必須刃磨正確,兩切削刃要保持對稱。鑽頭後角過大,會產生紮刀現象,引起顫振,使鑽出的孔呈多角形。應修磨橫刃,以減小鑽孔軸向力。

2、鑽頭必須裝正,保持鑽頭鋒利,用鈍後應及時修磨。

3、合理選擇鑽頭幾何參數和鑽削用量,按鑽孔深度要求,應盡量縮短鑽頭長度、加大鑽心厚度以增加剛性。使用高速鋼鑽頭時,切削速度不可過高,以防燒壞刀刃。進給量不宜過大,以防鑽頭磨損加劇或使孔鑽偏,在切入和切出時進給量應適當調小。

4、充分冷卻潤滑,切削液一般以硫化油為宜,流量不得少於58L/min,不可中途停止冷卻,在直徑較大時,應盡可能采用內冷卻方式。

5、認真注意鑽削過程,應及時觀察切屑排出狀況,若發現切屑雜亂卷繞马上退刀檢查,以防止切屑堵塞。還應注意機床運轉聲音,發現異常應及時退刀,不能讓鑽頭在鑽削表麵上停留,以防鑽削表麵硬化加劇。

在西安不鏽鋼工件上鑽孔常采用麻花鑽,對淬硬不鏽鋼,可用硬質合金鑽頭,有條件時可用超硬高速鋼或超細晶粒硬質合金鑽頭。鑽孔時扭矩和軸向力大,切屑易粘結、不易折斷且排屑困難,加工硬化加劇,鑽頭轉角處易磨損,鑽頭剛性差易產生振動。因此要求鑽頭磨出分屑槽,修磨橫刃以減小軸向力,修磨成雙頂角以改善散熱條件。

企业至成立以來,以誠信、合作、雙贏、發展為經營宗旨,堅持價格最優、用戶、信譽的營銷理念,在市場上獲得了良好的口碑。
