刀具Tool(中文5000字,论文3500字)
切削速度只有在对表面粗糙度不做要求的时候才不重要。粗加工最主要的是尽快地去除过剩的零散材料。表面粗糙度只有在精加工的时候才是重要。不像粗加工 ,精加工的加工速度慢。带断屑器的右旋刀具 , 胜于标准角度的刀具 , 如图 9-10 A, 是专为深度切削而设计 , 举例来说 , 一 个5/16英寸的方形刀具刀刃最多只能切深 5/16英寸,而且一个 8 毫米方形刀具刀尖块将会切削到8 毫米深处, 这一个刀具刀尖块将会非常快切除多余的金属。薄片处理的优点是 , 在小的紧密刀片中被细化。这种刀具也是一个很好的精加工刀具。但请不要混淆了薄片刀具和带断屑器的刀具。一个断屑器实际上是切断对刀具反作用的切屑薄片。
Cutting speed only in the surface roughness not required when it is not important. Rough the most important thing is to remove the excess material scattered. Only in surface roughness of the finishing time is important. Unlike rough, finishing the slow processing speed. Chip off with the D-knives, better than the standard point of knives, in Figure 9-10 A, is designed for cutting depth and design, for example, a 5 / 16-inch box cutter blade of the maximum depth of cut 5 / 16 inches, and an 8 mm square block will be cutting knives Corner to 8 mm deep, this tool will be very fast Corner block removal of surplus metal. Slice merits of the deal with that, in a small blade was close thinning. This tool is also a very good finishing tool. But please do not confuse the thin band Tool and Tool-off crumbs. A chip-off is actually counter-productive tool to cut off the chip flakes. |
