Abstract
A kind of aluminium straight fluted drill chip area aftertreatment technology, belong to high-precision numerical control machine aluminum workpiece drilling processing technique field, and in particular to a kind of aluminium straight fluted drill chip area aftertreatment technology.Burr on preceding knife surface on straight fluted drill chip area etc. is purged；Super grinding is carried out to preceding knife, the roughness of knife reaches certain Ra values before making；Grease is moistened with the hairbrush containing bortz powder to be processed by shot blasting, rake face is reached mirror effect to the preceding knife after super grinding.Runny aluminium skimmings is not adhered to, area to be machined is quickly discharged in the presence of slight cutting force, it is ensured that processing is smoothed out.
Description
Technical field
The invention belongs to high-precision numerical control machine aluminum workpiece drilling processing technique field, and in particular to a kind of aluminium is with directly
Gouge bit chip area aftertreatment technology.
Background technology
Because aluminum workpiece is in drilling, aluminium skimmings are soft and viscous, and cutting force caused by drilling is not enough to be excluded quilt
Machining area.
Therefore drill bit internal has two flushing holes, the cutting fluid that machine tool chief axis center is sprayed, passes through this two flushing holes
The bottom surface for being processed hole is directly reached, while play a part of cooling, while by the aluminium skimmings of excision from the bottom edge in processed hole
Chip area and go out machining area, drill bit and workpiece quality are damaged in chip area to ensure that aluminium skimmings will not rest on.Shortcoming is very
More Digit Control Machine Tools do not have the ability of alignment of shafts water outlet, can not use this cutter.
The content of the invention
The defects of to overcome present in prior art, the present invention provide a kind of aluminium and post-process work with straight fluted drill chip area
Skill, it can solve the problem that above-mentioned technical problem.
Technical scheme is used by the invention solves its technical problem：After designing a kind of aluminium straight fluted drill chip area
Handling process, carried out successively according to step：
Step 1：Burr on preceding knife surface on straight fluted drill chip area etc. is purged；
Step 2：Super grinding is carried out to preceding knife, the roughness of knife reaches certain Ra values before making；
Step 3：Grease is moistened with to the preceding knife after super grinding with the hairbrush containing bortz powder to be processed by shot blasting, before making
Knife face reaches mirror effect.
Preferably, the Ra values described in step 2 are less than 0.15 μm.
Preferably, it is wooden to include different stearic acid, pentaerythritol triacrylate, condensation and modification for the grease described in step 3
Plain sodium sulfonate, sodium metasilicate, the consumption (mass fraction) of each raw material are：
Preferably, the consumption (mass fraction) of each raw material is：
Beneficial effect is possessed by the present invention：
1st, after the present invention to straight fluted drill chip removal rooved face by being processed by shot blasting, aluminium skimmings are made in no central water outlet
Under help, still area can be processed by smooth incomparable rake face " skidding off " by the cutting force of a little, ensure processing
Be smoothed out.
2nd, the present invention makes rake face reach mirror effect, runny aluminium skimmings is not adhered to, in the work of slight cutting force
With lower quick discharge area to be machined, it is ensured that processing is smoothed out.
