Description
Technical field
The invention belongs to abrasive machining and abrasive material abrasive grain technical fields, and in particular to a kind of more particle agglomeration type abrasive grain bodies,
Preparation method and applications.
Background technique
Abrasive machining is the process that material removal is carried out using hard minerals (abrasive material) particle as cutting element
It is referred to as.Abrasive machining method and process adaptability is extremely strong, process is numerous, such as grinding, grinding, polishing, honing, microstoning,
Free abrasive machining, Compostie abrasive particles processing etc., have a wide range of application, can be to metal, ceramics, glass, stone material, refractory material, mixed
The a variety of materials such as solidifying soil, bone, composite material are processed, can be to plane, periphery, spherical surface, involute flank, spiral table
Realize the various Precision Machinings such as waste, thick, essence and microstoning in the various surfaces such as face, free form surface；Abrasive machining lathe is related to planting
The most lathe of class is widely used and a variety of industries such as machine-building, light industry, building, refractory material.I.e. many is difficult to add
The material of work can be processed by abrasive grain, and abrasive machining is widely applied important processing method in various industries.
Since abrasive grain and cutting size are tiny, grinding force is small, the abrasive grain for participating in cutting is numerous, so abrasive machining can be very
It is easy to get the surface of high-precision low surface roughness.Very subtle abrasive grain is especially applied, nanoscale cutting can be obtained
Sword can obtain 0.1 μm of surface accuracy, surface roughness to realize very thin micro-cutting, obtain defect-free surface
The finished surface of Ra0.008~0.025 μm.Therefore abrasive machining be Ultra-precision Turning main means, modern aerospace,
There is important application in the high-tech areas such as precision machinery and instrument, electronic information, sophisticated weapons, small-sized and micromachine.
With the fast development of science and technology, increasingly higher demands are proposed for the processing of grinding and polishing in various industries.
Wherein efficiently with it is high-precision be to require highest two parts.Traditional abrasive material is the mono-crystalline structures of individual particle, and crystal itself is one
A complete big crystal grain, monocrystalline are the individual particles with perfect crystal shape, and the lattice inside particle is periodic arrangement, are had
Anisotropy, particle surface is relatively smooth, and cutting edge quantity is few, and cutting force is weak.And individual particle cutting edge is big and hard, scratches tight
Again, it is ruptured when while by external impacts along cleavage surface, particle can become smaller quickly, so that the life-cycle of abrasive material obviously shortens.
For being made into bonded abrasive tool, due to single crystal grain abrasive material have cleavage surface, in grinding process, using one section when
Between rear edge surface wear it is easy to appear passivation, and monocrystalline is easy whole extract from bonding agent and loses ground effect, and cannot
The effectiveness for giving full play to abrasive material, the service life for resulting in grinding tool is short, grinding rate is low.It is said from polishing application aspect: in IT industry, firmly
Disk and magnetic head need very high surface smoothness and flatness, roughness Ra value after Analysis of Optical Fiber Connector End-face in Polishing in optical communication
It needs in nanoscale；The grinding and polishing of sapphire wafer not only requires very strong cutting force in LED industry, and requires chip table
Face no marking.Above-mentioned high-precision requirement, being ground using traditional mono-crystalline structures abrasive material individual particle cannot achieve.
In order to overcome defect when single crystal grain is as abrasive material in the prior art, usual big single crystal grain in the prior art
It performs etching, manufactures into cavernous body shape, avoid particle when by external impacts along the rupture of cleavage surface, also improve and grinding
Cut the processing efficiency in polishing process.But because single crystal grain is in etching process, from outward appearance to inner essence perform etching, outer surface is carved
The degree of erosion is more serious, and internal etching lesser extent, causes the inconsistent of inside and outside hardness；And single crystal grain is due to forming
The hardness of mechanism and cause, between every abrasive material and every abrasive material and position that same abrasive material is different is all different, so
The degree of etching is also different, and cause workpiece to be machined surface in this way has that scuffing, flatness are inadequate.
Agglomeration type abrasive grain body is a new technology, and agglomeration type abrasive grain body is to pass through agglomerate by multiple lesser single crystal grains
Bulk particle made of bonding coalescence, shape do not have that single crystal grain is regular, and surface is presented various rough surfaces, and when grinding is answering
Under power effect, while external single crystal grain successively falls off, expose new sharp cutting edge, is able to solve single crystal grain mill
The whole extraction from matrix of material, too early the problem of falling off, to give full play to the effectiveness of agglomeration type abrasive grain body.And its cutting force
Small, workpiece to be machined surface roughness is low；During grinding and polishing, agglomeration type abrasive grain body can be used as sphere, spherome surface
On have multiple cutting edges, during the polishing process, sphere slowly rolled on being polished workpiece, using its surface cutting edge plough
Plough, workpiece surface no marking, and there is very strong grinding force.It can be prepared not according to the needs of grinding or polishing etc.
The abrasive grain body of similar shape, to carry out high-precision, efficient grinding or polishing etc. to workpiece.
Summary of the invention
For the technical problems in the prior art, in order to achieve the above object, the present invention provides a kind of more particles
