Description
Technical field
The present invention relates to a kind of method to bronze boart boart wheel disc precise dressing, belong to high-precision diamond cutter system
Make technical field.
Background technology
With the development of the sophisticated technologies such as nuclear energy, laser, astronomical telescope, the effect of Ultraprecision Machining is increasingly heavier
Will, it has also become the mark of a national manufacturing industry highest level.In Ultra-precision machining, accurate high-performance lathe and extremely steady
It is essential to determine processing environment, high precision cutting tools are also most important.At present, traditional mechanical grinding method is still high-precision gold
The main method of diamond cutter manufacture.In the machinery sharpening technique of diamond cutter, directly acted on just with diamond cutter
It is abrasive disc.The abrasive disc surface irregularity of rotation can influence the microscopic contact state of cutter and emery wheel card at a high speed, change knife
Have the dynamic grinding depth in grinding, produce the vibration between cutter and emery wheel card, form card abrasive particle to the micro- of cutter
Impact is seen, so as to directly influence the quality of the diamond cutter sharpened out.Therefore, in order to ensure the card of abrasive disc essence
Degree, improves the grinding quality of diamond cutter, and the precise dressing technology of research emery wheel card has good practical value.
Metal anchoring agent diamond wheel is formed using diamond abrasive grain with metal powder sintered, is embedded in bonding agent
Diamond abrasive grain remains high rigidity, anti abrasive feature, therefore the finishing to skive is relatively difficult.Domestic and foreign scholars
Many research work have been done in the dressing technique field of the super hard abrasives such as skive, have developed some effective technique sides
Method.
Diamond turning method is traditional conventional grinding wheel dressing method.Turning method dressing process is similar to turning side on lathe
Method, diamond dresser reach stone face with certain finishing depth and feed speed finishing stone surface
Permissible accuracy.Turning method includes the finishing of single-point diamond slate pencil and the finishing of multiple spot diamond pen, and its finishing cost is low, dressing accuracy
It is high.
Grinding dressing method is to use silicon carbide grinding wheel in a manner of being ground to repair the method for skive.Repairing
In, its dressing efficiency is low, and silicon carbide sand foot wheel abrasion is quickly.Japanese scholars village department gram hero proposes one kind and utilizes cup green silicon carbide
The method of crushing metal anchoring agent diamond wheel, the green silicon carbide abrasive particle to be come off from finishing emery wheel during finishing can be gone
Except the metallic bond around diamond abrasive grain, during to skive shaping, while can also realize to its dressing.
The dressing accuracy of this dressing method is relatively low.
Rolling dressing method is directly contacted using the skive being trimmed of rolling freeing wheel and rotation, boart boart
Wheel drives rolling wheel to rotate, and is repaired using rolling effect between the two and Relative friction effect.Rolling wheel can be
Plain wheel, hard alloy roller or hardened steel roller.This method is simple, but repairs ability, and dressing accuracy is low.
On-line purification method is a kind of crushing technology to be grown up by Japanese scholars in 1985.The technology develops
Initial stage mainly for ceramic material grinding process, carries out restoring on line to metal anchoring agent diamond wheel, found for grinding
Hard brittle material, this dressing method effect are preferable.This method is to do anode with metal bindnig agent extra hard abradant sand wheel, passes through electricity
Solution method exposes emery wheel abrasive particle, forms sharp cutting edge with chip space to realize the finishing to emery wheel, and dressing efficiency is high, but
Trimming device is complicated.
Laser truing and dressing is to irradiate boart boart wheel surface using some strength laser, by adjusting laser power density,
Make its both higher than bonding agent remove threshold value, again higher than diamond particles remove threshold value, it is possible to while remove diamond abrasive grain and
Its bonding agent, so as to realize the shaping of emery wheel and dressing.This method dressing efficiency is high, can repair complex profile, but repair
Precision is undesirable.
The content of the invention
The purpose of the present invention is to meet high-precision diamond tool mechanical grinding technology to precision diamond abrasive disc
Demand, propose that a kind of end surface full jumping is better than 2 μm of bronze boart boart wheel disc precise dressing method.
