310s不銹鋼管高速切削加工的難點

310s不銹鋼管銷售電話:13920191906

310s不銹鋼管熱強度高、韌性大對CNC高速切削不適應奧氏體類不銹鋼與馬氏體類不銹鋼,其硬度和抗拉強度不高,只相當于40號鋼,但延伸率、310s不銹鋼管斷面收縮率和沖擊值卻比較高。這樣在CNC高速切削過程中就不容易被切斷,切削變形時所消耗的功相當大。相對來說,不銹鋼在高溫下的強度降低較少。實踐證明,在相同切削溫度的作用下,由于熱強度高導致不銹鋼切削比普通碳素鋼加工難度大。在CNC切削加工過程中,所產生的大量熱能未能迅速排出,必然會傳遞給刀具,310s不銹鋼管使切削部位溫度升高。310s不銹鋼管同時由于排屑比較困難,尤其是不斷屑,使被切削下來的切屑產生擠塞,特別是加工內孔,切屑擠塞更加嚴重。另外,刀具因受截面形狀的限制,再加之本身強度較差,加工中容易產生振動,310s不銹鋼管刀尖很容易在切削過程中由于局部溫度過高而燒壞或因振動太大而崩裂。
