Cutting tool is a necessary tool in machinery is made, so everybody calls cutting tool the tooth of machine treatment. The most important in machine treatment is cutting tool, a good numerical control cutting tool can process on 1000 products, but if choose improper cutting tool, perhaps use a knife undeserved, the likelihood machined cutting tool of a few products to discard as useless.
So how to choose numerical control cutting tool correctly? This problem is perplexing a lot of person of the same trades, why was same cutting tool just installed did not cut a few knives, edge has gap, perhaps cut did not move, and treatment is other the product is very good with, perhaps use knife others likewise can use very long, and oneself discarded as useless with a few, this picks a knife namely undeserved cause.
The classification of cutting tool is very much, appearance looks be like same the milling cutter the standard, immanent construction is completely actually different, in 2 dimension detect the distinction that issues you to just can discover them. Cutting tool cent is cutting tool of cutting stainless steel, cutting tool of cutting aluminium alloy, cutting is plastic cutting tool, press a metal kind cent, cutting tool is divided again for white steel cutting tool, wolfram steel cutting tool, PCD cutting tool, common we are the most commonly used is wolfram steel cutting tool. Next we say the method picking a knife of wolfram steel cutting tool, the hope is right of machine treatment industry you are useful.
If you are treatment stainless steel, cutting tool chooses the wolfram steel milling cutter of the horn after circular arc commonly, had better be blade leaves the area that has 0.03, such knife photograph contrast is more durable. And the horn after end panel cannot too big, stainless steel belongs to horniness material, so opposite for do not want too sharp cutting tool cutting, too sharp and easy collapse is short of.
And if you are to machine aluminium alloy to need to choose,compare sharp cutting tool relatively, choose the wolfram steel milling cutter of the horn after plane commonly, external diameter of this kind of milling cutter does not leave first flank commonly, and hind the horn after horn compares circular arc wants big, normal for the horn after the cutting tool end panel that stainless steel chooses is 8 degrees, and the horn after aluminium alloy needs to use 12 degrees.
The cutting tool demand with plastic treatment is some higher, the horn after choosing external diameter commonly, horn before knife chamfer, horn before end panel compares big cutting tool, and knife chamfer had better be polish of essence of life, the product surface that such cutting tool treatment comes out is bright and clean the meeting that spend ability achieves a requirement.
Integrated above when to choose knife method, mix actually in daily life same. Chop bavin to cannot use too sharp knife for instance, and cut the cutting tool with very keen demand of bean curd criterion, it is to cut otherwise bad. Jump over good thing to want to choose namely relative to blunter cutting tool, and the speed when treatment cannot too fast, softer thing should jump over sharp cutting tool, and speed wants fast. This is the simplest method picking a knife in machine treatment.
