Description
Technical field
The invention belongs to super hard abrasive processing technique fields, and in particular to outside a kind of laser near-net-shape structuring diamond
The preparation of circle grinding wheel and its dressing method.
Background technology
As modern processing adds towards high speed, efficient, accurate, automation direction development and some novel hardly possiblies
The conventional abrasive materials such as the appearance of work material, silicon carbide and corundum grinding tool cannot fully meet modern grinding and require.And diamond etc.
Super hard abrasive is due to having the hardness of superelevation and to the adaptability of difficult-to-machine material, the use in modern processing manufacturing industry is more next
It is more extensive.
The skive used in production at present is usually to be made using multi-layer sintering or single layer electroplating technology, abrasive grain
It only mechanically embedded, be embedded in binder course, hold is little, is easy in the heavier processing of load because of hold deficiency
And abrasive material is caused to fall off too early, it causes to waste.On the other hand, it is random distribution being sintered with abrasive material in plating tool, abrasive grain
Proud exposure is little, and chip space is smaller, and the adherency that abrasive dust is easy tod produce in grinding blocks, and reduces the processability of tool
Energy and service life.
Therefore, people are imagining always and are seeking a kind of abrasive material that can realize bonded abrasive tool in three dimensions in recent years
The interior manufacturing technology that can be arranged on demand and firm chemical bonds and the coated method of the abrasive grain of metallurgical binding so that abrasive grain has
There are larger exposed height and controllable arrangement, meanwhile, and have larger hold.It can either meet part grinding to obtain
The requirement of machining accuracy and high efficiency, and Grinding heat injury and lift-off grinding wheel service life can be reduced to the maximum extent
Effect.
To solve the above-mentioned problems, domestic and foreign scholars study abrasive grain ordered arrangement and wheel face structuring,
It was found that wheel face structuring can effectively improve grinding efficiency, grinding force and grinding process energy expenditure are reduced, is increased
Big wheel face chip space, improves cooling and lubricating condition, reduces grinding temperature and grinding skin damage, efficient dry abrasive cutting,
Creep feed grinding, hard brittle material accurate grinding, hard-cutting material grinding, the manufacture of regular veins surface etc. have important meaning
Justice.But be to carry out subtracting material processing after forming grinding wheel making for the processing of laser surface structuring, efficiency is low and causes
A degree of waste.
In addition, for the soldering of novel super-hard abrasive material production method vacuum high-temperature and high-frequency induction brazing, the protrusion of abrasive grain
Height higher, hold is stronger, and grinding temperature is lower, cutting force smaller, but two kinds of super hard abrasive manufacture crafts also there are many
Deficiency, fabrication cycle is long, and thermal deformation easily occurs for matrix, and production cost is high.Processing method, thickness are brazed for the laser of powdering
Uniformity can not ensure that the too thick solder and matrix of easily leading to of powdering can not combine closely, and powdering is too thin under the premise of prior art
It can not ensure the integrality of solder again.For spraying type laser be brazed processing method, abrasive grain combined with solder it is insecure, it is added
Work grinding tool falls off seriously in grinding process, and processed surface undulation is excessive, is unable to reach the job requirement of grinding tool.
