Abstract
The invention discloses an artificial diamond compact cutter grinding method. The artificial diamond compact cutter grinding method includes that a cutter is rotated by 360 degrees when a grinding disc rotates to grind an artificial diamond compact cutter, and cutting direction is changed at any time to expose crystal orientation easy to cut. The artificial diamond compact cutter grinding method has the advantages that high efficient processing is realized, product quality is remarkably improved, grinding consumption is greatly reduced, and the like.
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 is composite polycrystal-diamond (Polycrystalline Diamond Compacts, abbreviation PDC) has high rigidity, high-wearing feature, high elastic modulus, isotropism and the relative high remarkable advantages such as thermal conductivity, become in recent years the preferred material of the high abrasion equipment such as high-grade machining tool, geology and oil bit, ceramic abrasive tool, processing of stone instrument, concrete instrument and valve seat spool, also become in the high-tech field of new one of the most vital pillar product.
Diamond is the highest material of nature hardness, adopts the adamantine grinding clearance of diamond wheel grinding very low, and skive consumption is very large, and the size of making diamond cutter is wayward.
Summary of the invention
The objective of the invention is for above-mentioned deficiency of the prior art, a kind of artificial diamond compact lathe tool grinding method be provided, can reach grinding heating little, consume the good effect of the little cutting edge roundness precision of emery wheel amount.
The technical solution adopted for the present invention to solve the technical problems is: artificial diamond compact lathe tool grinding method may further comprise the steps:
1) regulates clamping fixture angle on the grinding attachment, diamond compact lathe tool to be processed is installed on the clamping fixture;
2) start the mill main shaft, the abrasion wheel grinding dish is rotated;
3) start the cutter rotary main shaft, make diamond compact lathe tool rotation to be processed;
4) start the swing slide unit, make the abrasion wheel grinding dish make reciprocally swinging;
5) regulate the feed of feeding planker, the beginning grinding;
6) the good lathe tool withdrawing of grinding, the dismounting cutter;
7) repeating step 1) to 5), finish the grinding of diamond compact lathe tool another side.
Grinding attachment described in the 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 described 360 ° of rotary jig main shafts below, 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 the swing slide unit of can horizontal direction making reciprocally swinging, and described mill main tapping is fixed on the described swing slide unit.
Adamantine Principle of Grinding and Cutting is to find free machining crystal orientation, adopts adamantine high rigidity crystal orientation to come the crystal orientation of grinding soft could realize high-speed cutting.Yet artificial diamond compact is different from single-crystal diamond, it is a kind of crystalline anisotropy's diamond particle composite, this material does not exist easy cutting and the problem that is difficult for cutting direction in macroscopic view, but actual it remains many small single-crystal diamonds on microcosmic, according to this principle, this artificial diamond compact lathe tool grinding device makes workpiece 360 degree revolutions when adopting grinding, simultaneous grinding dish High Rotation Speed, change by this motion has reached that each particle diamond particulate all can produce cutting movement with mill in the processed diamond compact cutter on 360 ° direction, and just like this, each particulate all can have free machining crystal orientation to come out and removed fast.So the clearance that common this grinding process is produced diamond cutter is very high, the emery wheel autophage is also very little, adding the required pressure of grinding in man-hour significantly reduces, the generate heat yield rate of minimum process tool of grinding has reached more than 98%, and the cutting edge roundness precision is good, cutting edge is highly polished, this technique especially when processing large plane diamond cutter effect more obvious.
The present invention has following outstanding beneficial effect: the grinding heating is little, the little cutting edge roundness precision of consumption emery wheel amount is good, highly polished, and grinding efficiency obviously improves, and product quality is high.
Description of drawings
Fig. 1 is artificial diamond compact lathe tool grinding apparatus structure schematic diagram of the present invention.。
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
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 described 360 ° of rotary jig main shaft 2 belows, 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 the swing slide unit 7 of can horizontal direction making reciprocally swinging, described mill main tapping 6 is fixed on the described swing slide unit.
With this grinding attachment the artificial diamond compact lathe tool is carried out grinding, concrete operation step is as follows:
1) regulates clamping fixture angle on the grinding attachment, diamond compact lathe tool to be processed is installed on the clamping fixture;
2) start the mill main shaft, the abrasion wheel grinding dish is rotated;
3) start the cutter rotary main shaft, make diamond compact lathe tool rotation to be processed;
4) start the swing slide unit, make the abrasion wheel grinding dish make reciprocally swinging;
5) regulate the feed of feeding planker, the beginning grinding;
6) the good lathe tool withdrawing of grinding, the dismounting cutter
7) repeating step 1) to 5), finish the grinding of diamond compact lathe tool another side.
This grinding attachment makes cutter adding 360 ° of rotations in man-hour, changes at any time cutting direction, is come out in free machining crystal orientation, thereby has realized highly-efficient processing, and product quality significantly improves, and abrasive material consumption significantly reduces.
More than be preferred embodiment of the present invention, all changes of doing according to technical solution of the present invention when the function that produces does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
