310s不銹鋼棒表面切削加工存在問題

310s不銹鋼棒加工電話:13920191906

310s不銹鋼棒切削過程中既有塑性變形、摩擦等伴隨現象,也會出現積屑瘤、加工振動等誘發現象,這些都會造成工件切削表面的不平度。此外,切削刃也會有殘留面積,310s不銹鋼棒切削刃的表面粗糙度也會反映在工件已加工表面上,這點在普通表面加工和脆性材料加工時可以被忽略,但在塑性材料的精密切削時卻是影響表面質量提高的關鍵因素之一。310s不銹鋼棒切削過程中的塑性變形、摩擦、振動、積屑瘤現象又都與切削參數、刀具幾何參數和刃口質量有關。

310s不銹鋼棒刀具材料對工件加工表面質量也有影響。目前加工鋁合金的刀具材料主要有硬質合金、人造聚晶金剛石(PCD) 和天然單晶金剛石。硬質合金的摩擦因數、310s不銹鋼棒導熱系數和硬度等方面都不及后兩者。天然單晶金剛石刀具不僅成本高,而且工藝性很差,目前只能做成車刀和刀盤飛刀,無法滿足310s不銹鋼棒產品鋁合金外殼的銑削加工,因此 PCD 是比較理想的刀具材料
