矿用信号电缆是一种信号传输工具。一般信号电缆传输的信号很小,为了避免信号受到干扰,信号电缆外面有一层屏蔽层,包裹的导体的屏蔽层,一般为导电布,编织铜网或铜泊(铝),屏蔽层需要接地,外来的干扰信号可被该层导入大地,避免干扰信号进入内层导体干扰同时降低传输信号的损耗。

但随着进给量和切削深度的增加,切削力会显著增大(进给量增大一倍,切削力约增大7%~8%,切削深度增大一倍,切削力几乎成倍增加),易使塑件产生变形而影响加工质量,甚至使工件报废。塑件表面粗糙度值还会随进给量的增大而增大,因此加工时应选择合适的进给量和切削深度。切削常用塑料的进给量和切削深度参见表2。束语在加工塑料制件时,应根据塑料的性能及加工条件、加工要求,选择合适的刀具材料,合理选择刀具的几何参数及切削用量,解决好塑料加工中的特殊问题,使刀具几何参数的切削用量达到**组合,以达到减小切削力,降低切削温度,保证加工质量,提高生产率的目的。
