Quality diamond saw blades the advent of the technical solutions

Against the status quo, through repeated practice , a set of production efficiency, quality diamond saw the advent of the technical solution .

    1 , the use of production performance and stability, coarse particles , good thermal stability (ti and tfi direct nearly ) the strength of diamond . Diamond cutting tools and matrix consisting essentially of certain process conditions on fixed on the base body , mainly on the diamond abrasive cutting action of the processing of different stone . Therefore, the raw material ( diamond ) quality, size and concentration on the diamond tool has a decisive role .
    2 , although charcoal powder into a strong element of improving diamond holding force . In the processing of diamond saw blades , diamond blade carcass if there is a good holding force , diamond blade is a good , not prematurely fall off, cutting sharp , high efficiency. Generally diamond surface by plating a layer of strong carbon compound , a metal element , such as plating, titanium, chromium , nickel, tungsten, etc., in order to improve the diamond powder with the bonding matrix , and helps prevent the diamond sintered at high temperature oxidation and graphitization ; also in the matrix powder can be added a small amount of strong elements of carbon powder , such as: molybdenum, chromium, tungsten powder. As these powders on the gold , diamond and affinity better wettability , sintering the diamond and the matrix metal alloy carbide surface is conducive to diamond and the chemical bonding with the matrix metal is metallurgically bonded , thus greatly improving the tire holding force of the diamond body .
    3 , the use of ultra-fine powder and pre-alloyed powder. Ultra-fine powder helps reduce the sintering temperature, increase matrix hardness . The pre- alloy powder mixture through the three-dimensional , greatly reducing the contact time of the powder and the air , to prevent premature loss of low melting point metal and segregation , and help to improve the strength of sintered products , increasing the gripping force of the diamond .
    4 ,to improve the diamond particle size ratio . Traditional ratio , the blade should be sharp more, spend more coarse diamond , and vice versa with a fine diamond . Indeed so, but still less than optimal efficiency. The hardness of the diamond tools and the elastic modulus, high technique , sintering at high temperature plastic deformation hardly occurs . Selected ratio, before sintering to improve the bulk density of the diamond particles , to improve the tool wear ratio is beneficial. After several experiments generalizations head coarse , coarse , fine diamond particles composed of three kinds , the optimum particle size ratio of 1:0.0227:0.071 .

    5, in the amount of rare earth matrix powder is added ( such as lanthanum , cerium , etc. ) . Binding agent can significantly reduce the wear performance, improved cutting efficiency of diamond blades .

    6, using a thermal sintering process cold , protective atmosphere for a vacuum sintering . Then carried through the cold sintering performance during sawing blade is very sharp increase in productivity a lot, and vacuum sintering protective atmosphere to prevent oxidation of the powder , activated sintering , both to improve blade performance, but also extend the graphite mold life and reducing production costs.
    7 , the correct welding process, nowadays diamond saw blades are high frequency welder garden to welding, welding heads prone secondary " burn-in" and head off phenomenon . Not only unsafe , and the impact of the production , it should be made ​​of high strength , good permeability silver solder pieces for welding processing.

In summary , depending on the stone texture, different sawing machine is adjusted , a reasonable choice and the proper use of the blade , the blade performance into full play, so as to get a good use of effects.
