One, arrange in order with preferred orientaton technology current situation is current, cloth has monolayer diamond or the grinding cutting tool of CBN is to use eletroplate, agglomeration or methods of all sorts of drill rod solder make. With eletroplating the monolayer on means cloth grinds the grinding cutting tool of bead, its exceed hard abrasive is secured with mechanical means clamp. The Yu Gao below average size is 40%~50% , its defect depends on grain arranging is random commonly, inaccuracy decides this means the dimensional volume that a bit is used between grain and carries cooling fluid. Consequently, in machining a process these spaces are jammed very easily by metallic bits, the worst is to bring about " burn " workpiece and make waste product. Because grain beyond is tall,the advantage of ideal structure is big and grain gap is big, improve what the metal worries bit to eliminate the transportation with cooling fluid greatly thereby, improved grinding ability and cutting tool life then. The particle size distribution that arranges in order still can assure those who machine security to rise. 1. Be like a Zhou Zhi, in the tradition eletroplate, diamond of bond of colophony, pottery and porcelain, metal (in the manufacturing process of CBN) goods, the majority is bond and diamond (CBN) abrasive mixes together, to prevent diamond slant analyse needs to join size liquid olefin or distilled water to wait, but accompany volatilize the volatilization of the portion and contaminative environment. And slant to what what cause shaking in manufacturing process analyse is helpless. Diamond distributings mediumly in bond carcass is random. Often arise very easily slant analyse and accumulation, in accumulation area diamond is couldn't get be used effectively and bring about waste, especially because diamond of 0 distances much grain is controlled not quite firm, serve as scarcely in grinding process and fall off by oneself. Current, limited company of tool of Henan China brilliant is home carry out exclusively in exceeding hard abrasive tool arrange in order / preferred the enterprise of orientaton. This technology already was used at colophony, pottery and porcelain 2006, eletroplate, in the goods of the bond such as the metal, obtain Henan saved award of achievement of great science and technology 2006. 2. General situation of research and development 2001 Korea " 2 with diamond industry company limited " cost 2 million dollar, discharge cloth system at finishing ARIX diamond in December 2004 (Automatic Array System) research and development, can be in production of diamond knife head arrange diamond automatically equably with best span, in overcoming groovy knife first-born to produce, diamond is arranged without foreword randomly and bring about curium a cut efficiency is low, the technical difficulty with brief life. ARIX arranges a system automatically to make grow life tool and curium quickly cut ability to get optimization, solved the problem that diamond tool efficiency and life contradict each other. ARIX craft can make the span of diamond is optimized and 100% get controlling, make curium cut efficiency to raise the oldest rate. Of the diamond in knife head distributing equably make curium a life raise one times, curium cut speed to rise 30% . Tool life is lengthened 100% . The rope of Shinhan company curiums in Korea project bldg. enjoys outstanding reputation, for example, seoul city built crossroads 2005, in the process that tear open change, its rope curiums show a real value, to the large structure that builds with ferroconcrete compose, with arrange diamond rope to curium in order cut is very convenient, and very big without generation noise and dirt. Shinhan company is made for stone lumber industry curium cut a tool while, stimulate a word finish machining domain, because this domain is chemical mechanical polish (CMO) nap implement the growth that underlines tool application with diamond, promoted nicety to machine industrial development. The company expects to be in the market share of 5 billion dollar, inside 5 years from current 2% rise 10% , the majority in this kind of growth is the knife head that after arranging systematic technology automatically to expand by ARIX, makes and obtain. 2005, shinhan company is 120 billion Han in amount of diamond respect sale yuan (1.

) of 200 million dollar, among them of sales revenue 60% outside coming from Yu Hai. 2, diamond distributings equably / the function of the function diamond tool that arranges in order depends on a variety of elements, among them the granuality of diamond and quality are the most crucial. The life of diamond tool, power is used up with curium cut efficiency the chroma of the span of the diamond of surface of tool of diamond of final be decided by, diamond, diamond is bulgy height, and the granuality of diamond and PPC value. 1.

The span of diamond should distributing equably / when be being arranged in order, diamond span but according to cut object and occupy curium cut a condition different implementation optimization. Via curiuming after cutting, discover, arrange in order curium the span of a diamond of 85% is 2~7mm, and common curium the scale of this span is 60%[2] only. The addition of diamond content is not big to cut load influence, but cut time is lengthened apparently, curium a life and efficiency rise apparently. 2.

Diamond chroma rises when diamond chroma when, arrange diamond to curium in order piece life rises into geometrical progression, keep good at the same time curium cut capacity, but rise further as pH indicator, curium cut ability to tend drop. Should use arrange without foreword curium piece curium when cutting, rise as diamond pH indicator, curium cut negative charge bigger and bigger, down to cannot very good curium cut. Amount to when diamond chroma 1.

2ct/cm3, initial stage curiums cut cannot undertake. And arrange in order curium piece criterion life rises 100% curium cut if speed is common curium piece euqally first-rate. 3.

The bulgy height of the bulgy height diamond of diamond affects the performance of diamond tool, curium especially cut efficiency and curium a life. The greatest bulgy height of diamond depends on the granuality of its itself. And control firm should concern with the character of diamond. When bulgy height increases diamond, force of cut of its place susceptive also will rise. If diamond can bear high cut power, curium cut efficiency to will get rising. Increase diamond bulgy height removes an option outside best character and granuality, increasing hold is important technical step. For example, use technology of diamond plating Fu, choose reasonable carcass recipe and use beforehand alloyed powder end is the important way that increases hold. 4.

The granuality of diamond and granuality of PPC value diamond and PPC are worth the function of pair of diamond tools, if it is cut efficiency, important to curium a life, power uses up the wear process with diamond tool and character to have,affect. 3, arrange in order / even distributinging method 1.

The grain that this kind of method uses method of manual cloth bead asks to be in commonly 0.

5mm above, small not applicable, although can undertake discharging cloth, very time-consuming, cannot use at dimensions to turn production. In recent years, people tries to come with manipulator cloth bead, capture as a result of what wear bead fail with dimensional lattice distributinging difficulty. 2.

Law of drill rod solder uses connection of solder of active drill rod, outside rising except intensity, the gap that wear bead is bigger than what eletroplate, of grain the 80%~95% that more than is as high as average size. Drill rod fuses as a result of the high temperature of solder flow drives the displacement that wear bead in solder process, and even appear " crowded caboodle " phenomenon, this kind of method is insoluble those who wear bead is preferred orientaton problem. And the position that still cannot determine grain and clearance. 3.

Song Jian of company of emery wheel of China of Taiwan of pattern plate law civilian doctor above all diamond distributing equably / arrange technical application to curium at head of knife of drill rod solder, platoon in order curium with the rope on. This kind toothed the diamond inside is arranged in three-dimensional space, the does not go diamond that can solve King Kong manson to have appearance period wave thoroughly distributings problem. Apply its at the platoon to curium again after, cannot curium before cut cut granite, the result shows, this kind new-style and toothed can the speed of minutely 1mm curiums cut, 3 times faster than traditional iron sand. Every carat diamond curiums cut area is as high as 1 square metre, approach fretsaw life. Graph 1 the platoon that has three-dimensional structure curiums knife head " diamond lattice " sketch map 4.
