Description
Technical field
The present invention relates to grinding-material field, more particularly to the method that can quickly prepare abrasive particle pattern distribution mill.
Background technology
Grinding is the main processing mode that machine components precise forming obtains with high-quality surface, is widely used in gold
The high-efficiency and precision processing of the materials such as category, ceramics, optical crystal.For grinding, emery wheel is to work after process and processing
Part surface quality and processing cost are particularly important, are to form the efficient, key of accurate grinding technology.Due to grinding skill actually
It is that the micro removal of material is processed so as to realize that the whole removing of workpiece material is removed by being fixed on numerous abrasive materials of grinding wheel surface,
Therefore the distribution of grinding wheel surface abrasive particle is huge to emery wheel performance impact.All the time, people all make great efforts how cause abrasive material or
The micro- abrasive particle group energy of person is enough to be distributed in grinding wheel surface according to certain mode, to ensure uniformly undertake cutting load between abrasive particle
Lotus, so as to effectively improve the grinding performance of abrasive particle, as disclosed a kind of base in Chinese invention patent publication number CN1528565A
In the abrasive material technology of preparing with pattern optimization of shell membrane cloth, Chinese invention patent CN101073882 discloses a kind of abrasive material three
Tie up optimized controllable arranged plating tool preparation method of multilayer etc..These methods are from different aspect for abrasive particle pattern arrangement emery wheel
The arrangement implementation issue of abrasive material in making is broken through, but made instrument still differs very with expected purpose of design
Far.To find out its cause, be existing method mostly just for abrasive grain placement mode, and have ignored high-performance emery wheel another is heavy
Want problem --- emery wheel contour accuracy problem.The high accuracy of emery wheel profile is the basic guarantee of high-precision workpiece shaping, but is tied
The influence of mixture layer thickness is very big.CN105965408A discloses a kind of preparation method of single layer of abrasive particles emery wheel, and its core point exists
In by runout compensation mechanism indirect control bonding agent even application, to solve the high sex chromosome mosaicism such as abrasive particle, but its equipment is complicated,
It is cumbersome.On the other hand, existing mesh screen, orifice plate, template material are mainly metal, ceramics etc., and cost is high and hardly possible is processed,
Patterns of arranging are few, and are only to play a part of dynamic abrasive grain locations limitation, do not play control bonding agent thickness
Effect.
