Description
Technical field
The present invention relates to machining equipment field, more specifically to a kind of tool bit for processing annular groove.
Background technology
In some engineering goods parts, the material for having a kind of product parts is stainless steel, and the trade mark of stainless steel is
0Cr17Ni4Cu4Nb, its heat treatment hardness value are 33~38HRC, and deep annular groove, annular groove are provided with product parts
The ratio of depth dimensions and width dimensions be more than 5, its dimensional tolerance or position of related features are typically all not more than 0.02~0.03mm,
Roughness is Ra0.8.When the width of this kind of annular groove is about 5mm (width of this example product parts annular groove is 5.04mm),
And during depth larger (this example 31mm) of annular groove, i.e. when the ratio of groove depth and groove width is more than 6, common processing method is general
There are following 2 kinds：
1st kind, processing round is bored at annular groove, removes part surplus；Electric Discharge Machining annular groove is taken to reach again
Figure.
2nd kind, deep annular groove is rough milled, groove width stays 0.15~0.20mm of allowance；Numerical control electric spark is taken again
Processing and forming annular groove reaches figure.
Under regular situation, above-mentioned processing method, they all can there is some defects, its common deficiency are as follows：
1) processing efficiency is relatively low.Either using brill round method or method for milling, then using edm forming method
Annular groove is processed up to figure, process time all slow length, processing efficiency is all than relatively low.
2) cost of processing is higher.Because annular groove is narrow and deep, the rigidity and intensity of drill bit or milling cutter are all
It is poor, cutter in penetration of a cutting tool or feed it is careless slightly is just easy to occur vibration in addition be broken off, occur cutter scrap or
Product parts are scrapped, and thus correspondingly increase manufacturing cost；If with numerical control electric spark processing and forming annular groove, electrode is manufactured
Cost and electric machining cost it is also all higher.
3) dimensional accuracy and surface roughness are all poor.Annular groove narrow and deep (this example groove depth and groove width
Ratio be more than 6), when using tool sharpening shaping, trembleed due to the rigidity deficiency easily unstability of cutter, along with cutting
Bits are difficult to smoothly exclude and occur extruding or touch scuffing machined surface, cause the dimensional accuracy and surface roughness of product parts
It is all poor.If with numerical control electric spark processing and forming annular groove, because galvanic corrosion thing is equally difficult to successfully discharge in annular groove
Come, cause galvanic corrosion thing in annular groove may again or be repeated several times electric discharge, so as to cause the dimensional accuracy of product parts and table
Surface roughness is all poor.
In summary, the problems such as how efficiently solving the high processing costs of annular groove and can not being processed and formed at one time, it is
Those skilled in the art's urgent problem at present.
