Description
Technical field
The present invention relates to the cutter that machining uses, and in particular to a kind of superfinishing reamer for being used to process cylinder deep hole.
Background technology
Reamer is a kind of finishing for hole and half rough machined cutter, can be applied to CNC machining centers.Due to existing
Reamer still has some deficits in structure design, therefore in the high cylinder deep hole of requirement on machining accuracy, it is generally difficult to improve processing essence
Degree, tolerance grade generally all in more than 0.015mm, to reduce tolerance grade to below 0.015mm, then cannot be guaranteed processing essence
Degree.
Therefore, how to solve above-mentioned the shortcomings of the prior art, become as the problem of the invention to be researched and solved.
The content of the invention
It is an object of the invention to provide a kind of superfinishing reamer.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of superfinishing reamer, including shank and it is connected with cutter head in the shank forward end；Wherein：
Along the length direction of reamer, decile does not open up at least three chip areas on the cutter head, and each chip area is along cutter head
Border spiral opens up, and forms on the cutter head formed with the several blades equal with the chip area quantity；
Wherein, the spiral angle of each blade is different；
Also, when the quantity of the blade is the odd number more than or equal to three, the included angle of each chip area is different；
When the quantity of the blade is the even number more than or equal to four, the included angle of centrosymmetric chip area is identical each other,
The included angle of non-centrosymmetrical chip area is different, and is opened positioned at each chip area of the cutter head radial centre lines homonymy
Angle of the v-groove sum is 180 degree；
Wherein, the bearing of trend on the land of each blade along the blade is provided with least two sections of cutting edges from front to back
Band, and adjacent two sections of cutting edge interbands have a drop, form each section of cutting edge band blade bearing of trend from front to back
Stepped setting from low to high；
In addition to the cutting edge band of most back segment is long land and processing of putting the first edge on a knife or a pair of scissors, each before most back segment described cuts
Land is cut to be short land and do not put the first edge on a knife or a pair of scissors.
Relevant content in above-mentioned technical proposal is explained as follows：
1. in such scheme, opened up by the not decile of chip area and the mutually different design of the spiral angle of each blade, can
Vibrated when reducing cutting to greatest extent caused by cutter, to improve the stability of processing, ensure the linearity and circle in processing hole
Degree.Each helical angle is respectively less than 70 degree.
2. in such scheme, forward short land cutting output is bigger, that does not put the first edge on a knife or a pair of scissors is designed with beneficial to progress for a long time
Reliable roughing, and the long land of most back segment then be used for carry out retrofit；More pass through the stair-stepping design
The process for processing hole can be from slightly promoting step by step to essence, and then the purpose of microstoning, make tolerance grade reach 0.015mm with
Under.
3. in such scheme, in each even number blade cutting edge band put the first edge on a knife or a pair of scissors width greatly with cutting edge band in each odd number blade
Put the first edge on a knife or a pair of scissors width.The wider width that puts the first edge on a knife or a pair of scissors be used for increase stability when cutting, and the narrower width that puts the first edge on a knife or a pair of scissors be used for reduce cut and hinder
Power, make cutting more brisk, avoid the abrasion of cutter, and then tool life, both are staggered brisk to realize
And smoothly cut.
4. in such scheme, the length of the blade is less than the length of the chip area, in order to chip removal.
5. in such scheme, the front end of each cutting edge band is obliquely installed to form a chamfering.The inclination of the chamfering
Angle is adjusted according to the material of machined material, and the meaning of chamfering is conveniently to be cut.
6. in such scheme, the rear end sharp point of outer rim progress of the cutter head is blunt.When the depth in processing hole is grown more than cutter head
When spending, hole wall can be avoided damage to.
Can be whole hard alloy 7. in such scheme, reamer of the present invention can be cold outside, can be interior cold, or welding hard
Alloy.
8. in such scheme, reamer of the present invention can be left-handed setting, or dextrorotation is set.
The operation principle and advantage of the present invention is as follows：
A kind of superfinishing reamer of the present invention, including shank and cutter head；Decile does not open up at least three chip areas on cutter head, along cutter head
Border spiral opens up, form cutter head on formed with several blades；The spiral angle of wherein each blade is different；When blade
When quantity is the odd number more than or equal to three, the included angle of each chip area is different；When blade quantity to be more than or
During even number equal to four, the included angle of centrosymmetric chip area is identical each other, the fluting of non-centrosymmetrical chip area
Angle is different, and is 180 degree positioned at each chip area included angle sum of cutter head radial centre lines homonymy；The sword of each blade
Back is provided with least two sections of cutting edge bands, and adjacent two sections of cutting edge interbands have drop, form each section of cutting edge band from front to back
Stepped setting from low to high；The cutting edge band of most back segment is long land and processing of putting the first edge on a knife or a pair of scissors, and other each cutting edge bands are
Short land and do not put the first edge on a knife or a pair of scissors.
Compared to existing technologies, the present invention can meet to process required precision of the hole tolerance in below 0.015mm, especially
It is adapted to the processing of various metals, the low problem of the efficiency as existing for being processed boring cutter before changing；To sum up, the present invention has processing
Stability is good, high in machining efficiency, process hole it is highly polished, precision is high the advantages of, and the long lifespan that cutter uses.It can substitute
Import cutter, there is considerable economy.
