On the next to improve the quality of high-quality concrete diamond blades technical solutions

Aligned with the status quo, the end of Britain repeatedly theory, a set of production efficiency, quality diamond saw blade skills programs available.
1, the choice of the production function stable, coarse particles, heat stable and good (ti and tfi straight near to) the high-strength diamond. What is essentially a diamond diamond carcass must process conditions under fixed on the operating base, mainly by diamond grinding agent, not the same as cutting role to process the stone. Thus, the original data (diamond) quality, particle size and concentration on the diamond thing has a decisive role.
 2, although charcoal powder into a strong element of progress diamond control force. In the processing of diamond saw blades, diamond blade carcass if there is a good operating force, diamond blade is a distinguished, not prematurely fall, when cut sharp, high power. Usually top end of the outer plating layer of diamond strong carbon compound, the constituent metal elements, such as plating, titanium, chromium, nickel, tungsten, etc., in order to progress with the matrix powder of diamond bonded and sintered at high temperature to avoid favor diamond After oxidation and graphitization; other top end of the carcass can also be powder, carbon powder of a few strong increase of elements, such as: molybdenum, chromium, tungsten powder. Because this type of powder gold, moisture resistance and better affinity diamond, diamond sintering metal carcass appearance constitute carbide alloys, diamond and matrix metal in favor of chemical bonding and Metallurgy contact, and greatly improved the carcass diamond manipulation force.
  3, to improve the diamond particle size ratio. Traditional ratio, the sharp tip to more, spend more coarse diamond, and vice versa with a fine diamond. Of course yes, but it has been less than optimal operating power. Because the hardness and elastic modulus of diamond art high temperature GUSHI abrasive grinding wheels  sintering is difficult when the onset of plastic deformation. Selected ratio, before sintering progress bulk density of the diamond particles on the progress of the tool wear ratio is advantageous. Britain at the end repeated test results usually head coarse, coarse, fine diamond particles composed of three kinds, the optimal granularity share 1:0.0227:0.071. 4, the choice of ultra-fine powder and pre-alloyed powders. Ultrafine powder sintering temperature dropped in favor of progressive matrix hardness. The pre-alloy powder, the top end of the three-dimensional mixing, greatly reducing the touching moments powder and air, to avoid premature loss of the low melting point metal segregation and contribute to the progress of the strength of sintered products, increase the operating force of the diamond.
 5, increasing the excess of rare earth  GUSHI concrete ring saw elements (such as lanthanum, cerium, etc.) in a matrix powder. Contact agent can significantly decrease the wear features progressive diamond saw blade to cut the power.
  6, a selection of cold thermal sintering process, maintain vacuum sintering atmosphere. Top end of the cold tip after sintering is reflected in a very sharp cutting process, many progressive power production while maintaining a vacuum sintering atmosphere to avoid oxidation of the powder, activated sintering, both the head progress function and prolong the graphite mold The number of longevity, but also to decrease production costs.
  7, the correct welding technology, nowadays Diamond Park saw both use high-frequency welding machines to weld, the  GUSHI colde saw blade welding head is easy to show the second "burn" and head off appearance. Not only unsafe, and the impact of production, and therefore should be used in high-strength, permeability good silver solder pieces for welding production.
