車床件螺絲材質的選擇技巧
發布者:handler 發布日期:2016-05-26
 車床件螺絲材質的選擇技巧 車床件在螺絲鎖付作業中,螺絲所占成本只有15%左右,而攻牙﹑其它配套零件及鎖伏作業占85%左右,所以從免除攻牙﹑減輕作業扭力﹑防止螺絲松動﹑提高螺絲鎖付的可靠性﹑降低成本等方面考慮,應優先選用非標車床件加工中的塞打螺絲。 塞打螺絲材質選擇 1﹑車床件低碳鋼:常用10#﹑15#﹑20#鋼,一般用于低強度螺絲,含碳量越低越容易加工但強度較差,在加工后不需熱處理即可直接表面處理后使用,成本較低。 2﹑中碳鋼:常用25#﹑35#﹑45#鋼,一般用于中高強度螺絲,含碳量越高越難加工但強度越好,加工后熱處理前強度較低,經熱處理及表面處理性能可有很大改善,強度較好且成本適中。 3﹑車床件不銹鋼:一般用SUS303﹑SUS304等不銹鋼,加工比較困難,一般用于高強度或特殊用途螺絲,加工后需熱處理,一般不需表面處理,雖然強度較好成本很高,一般為碳鋼螺絲的3?5倍,除非特別需要建議不用。
