As the development that decorates data market, it is to increase greatly to the demand of stone material, in stone material treatment, yi Yue comes to the demand of diamond tool bigger. However, the diamond on market of uptodate cloud float curiums a quality is not quite good. Often be to begin very sharp, the diamond when cutting an in part gives blade bad, fall off serious, or cut amount is little, a man-hour is changed for many times curium titles, bring about treatment efficiency is not tall. Stone lumber company is pressing need is efficient and high grade, sexual price curiums than good diamond piece. Be aimed at the current situation, course of our person of the same trade is carried out for many times, explore eventually give to produce efficient, high grade diamond to curium piece technical program. 1, use productivity to be able to be stabilized, thick grain, thermal stability is good (Ti and TFi are close to continuously) excel in diamond. Diamond tool basically is secure below certain technology condition by diamond and carcass go up in working matrix, basically rely on diamond grind action of agent, cut to process different stone material. Accordingly, raw material (diamond) quality, granuality and chroma are having conclusive effect to diamond tool. 2, although enter element of strong charcoal powder, increase diamond hold. Curium in diamond a treatment process is medium, if body of knife the first-born has good hold to diamond, diamond can give blade good, won't fall off prematurely, benefit of cut Shi Feng, efficiency is tall. Can pass Fu of pair of diamond surface plating commonly compound of a strong charcoal, form tantalum, wait like plating, titanium, chromic, nickel, tungsten, in order to raise the bond that diamond is the same as carcass powder, be helpful for preventing the diamond oxidation after high temperature agglomeration and graphitization; Still can pass additionally in carcass powder, add elements of a few strong charcoal powder, be like: Pink of molybdenum, chromic, tungsten. As a result of this kind powder is opposite gold, the wetability of firm stone and affinity are finer, be in when agglomeration diamond and carcass metal surface form char content alloy, the chemical bond that is helpful for diamond and carcass metal and metallurgy are united in wedlock, raising carcass greatly thereby the hold to diamond. 3, the granuality that improves diamond deserves to compare. The tradition deserves to compare in, knife head wants some sharper, some more multi-purpose thick bead diamond, use granule diamond conversely. Indeed so, but from beginning to end short of is optimal work efficiency. Because the hardness of diamond and art of stretch model quantity are high, produce plasticity very hard when high temperature agglomeration to be out of shape. Had chosen deserve to compare, increase the accumulation density of grain of the diamond before agglomeration, it is advantageous to raising the wear and tear of cutting tool to compare. Reach through many second experiment general knife head is thick, medium diamond of 3 kinds of grain comprises thick, granule, its are optimal size scale is 1: 0. 0227: 0.
071. 4, use super- fine powder and beforehand alloyed powder end. Exceed fine powder to be helpful for dropping firing temperature, raise carcass hardness. And beforehand alloyed powder end, pass three-dimensional and stereo batch mixing, shortened greatly powder and airy contact time, prevent metal of low melting point premature prediction of a person's luck in a given year and slant analyse, be helpful for increasing the strength of agglomeration goods, increase the hold to diamond. 5, right amount rare-earth element is added in carcass powder (wait like rare earth lanthanum, cerium) . The abrasiveness that can lower bond apparently can, raise diamond to curium piece cut efficiency. 6, use cold press craft of one hot agglomeration, undertake vacuum protects atmosphere agglomeration. The knife head that agglomeration has again after connecting super-cooling to press is curiuming in cutting a course, be behaved very sharp, manufacturing efficiency rises a lot of, and agglomeration of vacuum protection atmosphere can prevent pulverous combustion, activated sintering, improved knife head performance already, prolonged the life of black lead mould again, still can reduce manufacturing cost. 7, correct welder art, nowadays diamond curiums field piece use high frequency welder to solder, when soldering appear extremely easily 2 times of knife head " burn " mix phenomenon. Not only insecure, and influence production, because this should use high strength, osmotic good silver-colored solder piece will undertake soldering machining production. Integrated above when, a piece of high grade and efficient diamond curiums piece develop a success namely. But the process is used in the production of diamond cutting tool in, very much to the influencing factor of cutting tool, still get " because of stone " according to quality of a material of different stone lumber, curium differently cut machine and adjust, logical choice is used correctly curium piece, make curium piece function is able to develop adequately, achieve favorable use result thereby.
