Description

A kind of super-abrasive grinding wheel dressing device

Technical field

The utility model belongs to grinding wheel manufacture and applied technical field, and in particular to a kind of super-abrasive grinding wheel finishing dress It sets.

Background technology

Super hard abrasive（Diamond and CBN）Grinding wheel, due to being the main hair of modern processing with high wearability Open up one of direction.Super-abrasive grinding wheel has excellent grinding performance, and antiwear property is strong, need not often modify.But first Begin to install and using after blunt, finishing is relatively difficult.Truer and finishing condition have significantly crushing quality It influences, not only influences the sharp degree of topography of grinding wheel and sharpening, but also the abrasion of influence grinding wheel, grinding force, grinding temperature And by the surface integrity of mill part.In recent years, with the progress of abrasive techniques and equipment and technology, the application of hard grinding wheel is drastically Increase, grinding wheel to be made can efficiently, the workpieces processing of high quality, the finishing problem of grinding wheel becomes to be increasingly urgent to.

The shaping methods of super-abrasive grinding wheel are more, and traditional have turning method, filing, electric machining method, laser method etc., but Turning method is only adapted to hard brittle ceramic bindnig agent extra hard abradant sand wheel；Filing shaping process is outmoded, and freeing wheel waste is big, whole Shape efficiency is low, unfavorable energy conservation and environmental protection；Electric machining method is suitable only for conductive-type metal bindnig agent extra hard abradant sand wheel；Laser method is fragile Bad superabrasive wheel textura epidermoidea.Traditional dressing method is squeezed by hard, that is, relies on contact roller for dressing or finishing grinding wheel and quilt The hard squeezing action modified between the abrasive grain of super-abrasive grinding wheel is modified, and the super-abrasive grinding wheel being trimmed is contacted first To being exposed abrasive grain outside, and super-hard abrasive hardness is high, wearability is strong, and it is extremely low to result in dressing efficiency in this way, finishing Complete super-hard abrasive naked state is poor.

The finishing of hard grinding wheel, is generally divided into shaping（Turing,Profiling,Forming）And dressing（Dressing, Sharpening）Two procedures, shaping are to carry out micro cutting to grinding wheel, and grinding wheel is made to reach required geometrical precision, And keep abrasive material tip micro- broken, form sharp sharpening.Dressing is the bonding agent removed between abrasive grain, makes have certain appearance bits between abrasive grain Space, and sharpening is made to protrude except bonding agent, form cutting edge.Hard grinding wheel will obtain good ground effect, shaping and repair It is sharp necessary proper.In addition, the cost of hard grinding wheel is very high, improperly finishing will cause to waste.

Application No. is the diamond shape faces of CN201110150393.0 to constrain the crowded mill super-abrasive grinding wheel of free abrasive grain speed change Dressing method discloses a kind of dressing method of free abrasive grain auxiliary, and the first stage provides abrasive grain liquid, squeezes wheel dress；Second Stage does not provide abrasive grain liquid.The finishing sequence of superabrasive wheel should be dressing after first shaping, and this method first stage is main It is dressing effect, second stage is mainly shaping operation, has overturned finishing sequence, has not had good finishing effect, and abrasive grain Liquid can also aggravate the consumption that diamond squeezes emery wheel while modifying hard grinding wheel.In addition, abrasive grain waste liquid can also cause environment Pollution.
