Diamond-impregnated wheel is mainly used for the size corrected the verticality on four side of ceramic tile and obtain setting, is various big specification potteries
Porcelain crystal brick, Imitation Rock Porcelain Tiles, polished bricks edging required tool.Traditional diamond-impregnated wheel is divided into point a tooth welded type edging wheel, entirety
Continous way edging wheel, the two are essentially identical in structure.
As shown in Figure 3,4, dividing tooth welded type edging wheel is first to mix diamond abrasive with metallic bond, passes through hot pressing
Diamond block is made in sintering, is then welded in certain arrangement mode in the shallow slot of steel matrix plane most outer, section and section
Between gap is set.This edging wheel is convenient for chip removal, and heat dissipation is good, but its production process is many and diverse, and properties of product stability is poor, compared with
Weak weld strength not only seriously constrains its application in dry method Speed Grinding, is also easy to that " fly cutter head " is caused to hurt sb.'s feelings
Accident.
As shown in Figure 5,6, whole continous way edging wheel is the diamond pre-burning locking nub that will be cold-pressed, is disposed directly at steel
On matrix, after mold is completed, enter furnace sintering.Such edging wheel eliminates welding sequence, and cutter head is good with substrate combinating strength
It is good, it is mainly used for the processing of Wall or floor tile dry method edging.But since its monolithic blade header structure is unfavorable for chip removal, grinding heat is difficult to turn
It moves, be easy to cause and burn knife and black surround phenomenon, be also difficult to meet the requirement of New Processing.In recent years, correlative study unit is drawn
Enter potsherd easy to wear, active designs channel of chip removal, the chip removal of emery wheel, heat dissipation performance have certain raising, but it manufactures work
Skill tends to be complicated, and production efficiency is low, and cost performance is not high.
For this purpose, related technical personnel have studied Quick-forming (Rapid Prototyping) technology, which rises in 20
The nineties in century is the part prototyping process for integrating computer technology, laser processing technology, new material technology.
Different from the method for traditional removal material manufacture part, rapid prototyping technology is to establish three in a computer by CAD software
Physical model is tieed up, and is discretized into a series of plane geometry information, passes through sweeping for the control heat sources such as laser beam or electron beam
Retouch direction and speed, using bonding, sintering, polymerization or chemistry with the means such as react and successively selectively process raw material, thus
Rapid accumulation goes out the increasing material manufacturing method of physical model.Currently used quick forming method has: Fused Deposition Modeling (FDM),
Stereolithography (SLA), layer separated growth (LOM), precinct laser molten sintering (SLS), 3 D-printing (3DP).In recent years,
Have also appeared LENS technology, it use in, the metal powder of the synchronous supply of high power laser fusing, successively sink according to predetermined trajectory
Product is substantially.Expense groups of stars etc. obtain the Ni-Cu-Sn alloy sample of no deformation using LENS technique, these methods generally use
Photosensitive resin, plastic film, nylon, metal or ceramic powder end can only manufacture the metal of respective material as moulding material
Or non-metal workpiece, it is rarely reported in the application of metal-bonded diamond arts.Therefore, it is necessary to further change
Into.
