Abstract
The invention discloses a kind of artificial diamond compact lathe tool grinding method, the method is while abrasive disk rotation carries out grinding to artificial diamond compact lathe tool, cutter also does 360 ° of rotations man-hour adding, change cutting direction at any time, come out in free machining crystal orientation, thus achieving highly-efficient processing, product quality significantly improves, and abrasive material consumption such as significantly to reduce at the beneficial effect.
Description
Technical field
The invention belongs to mechanical grinding device technique field, is a kind of artificial diamond compact lathe tool grinding method specifically.
Background technology
Diamond compact and composite polycrystal-diamond (PolycrystallineDiamondCompacts, be called for short PDC) there is the remarkable advantages such as high rigidity, high-wearing feature, high elastic modulus, isotropism and relative high thermal conductivity, become the preferred material of high-grade machining tool, geology and oil bit, ceramic abrasive tool, processing of stone instrument, concrete cutting tool and the contour wearable device of valve seat spool in recent years, also become one of the most vital pillar product in high-tech field of new.
Diamond is the material that nature hardness is the highest, and adopt diamond wheel grinding adamantine grinding clearance very low, skive consumption is very large, and the size manufacturing diamond cutter is wayward.
Summary of the invention
The object of the invention is for above-mentioned deficiency of the prior art, a kind of artificial diamond compact lathe tool grinding method is provided, the effect that grinding heating is little, the little cutting edge roundness precision of consumption emery wheel amount is good can be reached.
The technical solution adopted for the present invention to solve the technical problems is: artificial diamond compact lathe tool grinding method comprises the following steps:
1) regulate clamping fixture angle on grinding attachment, diamond compact lathe tool to be processed is installed on clamping fixture;
2) start mill main shaft, abrasion wheel grinding dish is rotated;
3) start cutter rotary main shaft, diamond compact lathe tool to be processed is rotated;
4) start swing slide unit, make abrasion wheel grinding dish make reciprocally swinging;
5) regulate the feed of feeding planker, start grinding;
6) the good lathe tool withdrawing of grinding, dismounting cutter;
7) step 1) to 5 is repeated), complete the grinding of diamond compact lathe tool another side.
Grinding attachment described in step 1) comprises mill main tapping and abrasion wheel grinding dish mounted thereto, also comprise clamping fixture, 360 ° of rotary jig main shafts and feeding planker, the mode that described clamping fixture is connected through the hinge is connected to below described 360 ° of rotary jig main shafts, and described 360 ° of rotary jig main shafts are fixed on the described feeding planker that can move up and down.
For making grinding efficiency higher, this grinding attachment also comprises horizontal direction can make the swing slide unit of reciprocally swinging, and described mill main tapping is fixed on described swing slide unit.
Adamantine Principle of Grinding and Cutting to find free machining crystal orientation, and the crystal orientation adopting adamantine high rigidity crystal orientation to carry out grinding soft could realize high-speed cutting.But artificial diamond compact is different from single-crystal diamond, it is the diamond particle composite of a kind of crystalline anisotropy, the problem of Cutting free and not easily cutting direction is there is not in this material in macroscopic view, but on microcosmic, it remains many small single-crystal diamonds to reality, according to this principle, artificial diamond compact lathe tool grinding device in the present invention adopts during grinding and makes workpiece 360 degree revolution, simultaneous grinding dish High Rotation Speed, reach each particle diamond particulate in processed diamond compact cutter by the change of this motion and all on the direction of 360 °, cutting movement can be produced with mill, and just like this, each particulate all can have free machining crystal orientation come out and be quickly removed.So the clearance that usual this grinding process produces diamond cutter is very high, emery wheel autophage is also very little, add pressure needed for grinding in man-hour significantly to reduce, the generate heat yield rate of minimum process tool of grinding reaches more than 98%, and cutting edge roundness precision is good, cutting edge is highly polished, this technique especially process large flat-face cutter time effect more obvious.
The present invention has following outstanding beneficial effect: grinding heating is little, consumption emery wheel amount little cutting edge roundness precision is good, highly polished, and grinding efficiency significantly improves, and product quality is high.
Accompanying drawing explanation
Fig. 1 is artificial diamond compact lathe tool grinding apparatus structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in fig. 1, artificial diamond compact lathe tool grinding device comprises mill main tapping 6 and abrasion wheel grinding dish 5 mounted thereto, comprise clamping fixture 3,360 ° of rotary jig main shafts 2 and feeding planker 1, the mode that described clamping fixture 3 is connected through the hinge is connected to below described 360 ° of rotary jig main shafts 2, and described 360 ° of rotary jig main shafts 2 are fixed on the described feeding planker 1 that can move up and down.Also comprise and horizontal direction can make the swing slide unit 7 of reciprocally swinging, described mill main tapping 6 is fixed on described swing slide unit.
Carry out grinding with this grinding attachment to artificial diamond compact lathe tool, concrete operation step is as follows:
1) regulate clamping fixture angle on grinding attachment, diamond compact lathe tool to be processed is installed on clamping fixture;
2) start mill main shaft, abrasion wheel grinding dish is rotated;
3) start cutter rotary main shaft, diamond compact lathe tool to be processed is rotated;
4) start swing slide unit, make abrasion wheel grinding dish make reciprocally swinging;
5) regulate the feed of feeding planker, start grinding;
6) the good lathe tool withdrawing of grinding, dismounting cutter;
7) step 1) to 5 is repeated), complete the grinding of diamond compact lathe tool another side.
This grinding attachment makes cutter adding rotation man-hour 360 °, and change cutting direction at any time, come out in free machining crystal orientation, thus achieve highly-efficient processing, product quality significantly improves, and abrasive material consumption significantly reduces.
Be more than preferred embodiment of the present invention, all changes done according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
