310s不銹鋼螺栓高速切削加工難加工的原因

310s不銹鋼螺栓銷售電話:13920191906


310s不銹鋼螺栓在CNC高速車削的過程中,由于刀尖對工件材料擠壓的結果使切削區的金屬產生變形,晶內發生滑移,晶格畸變,組織致密,機械性能也隨著發生變化,310s不銹鋼螺栓一般切削硬度也能增加2~3倍。CNC切削加工硬化層深度可以從幾十微米到幾百微米不等,因此前一次走刀所產生的加工硬化現象對下一次走刀切削產生不利影響,310s不銹鋼螺栓而且加工硬化層的高硬度導致刀具特別容易磨損。強大的加工硬化趨勢不利于不銹鋼零件的CNC切削加工。

在CNC切削過程中,310s不銹鋼螺栓切削碎屑很容易粘附或熔著在刀尖和刀刃上,形成積屑瘤,造成工件加工表面的表面粗糙度惡化,同時增加切削過程中的振動,加速刀具磨損。而且大量的切削熱無法及時傳導出來,甚至切削產生的熱量也無法傳導到切屑的整體上,造成傳入刀具總熱量比普通碳素鋼多,310s不銹鋼螺栓栓使切削刃在高溫下喪失切削性能。切屑的粘附性強、導熱差對CNC切削產生不利影響
