With the decoration materials market development , greatly increased the demand for stone , stone processing, increasing demand for diamond tools . However, the current market diamond saw on Yunfu quality is not good enough . Often start very sharp, diamond- cut to half when the blade is not good, shedding serious , or less cut the number of man-hours to change a blade head several times , resulting in processing efficiency is not high.

    Stone enterprises need efficient high-quality, cost-effective good diamond saw .

    The status quo , after repeated practice , a set of production efficiency, quality diamond saw the advent of technology solutions .

    1, with stable performance, coarse particles , good thermal stability (ti and tfi direct nearly ) high-strength diamond . Diamond tools consisting essentially of diamond on the carcass under certain conditions fixed working base , mainly by diamond grinding agent, to process various stone cutting action . Thus , raw materials ( diamonds ) mass , particle concentration on the diamond tool has a decisive role.

    2 , although charcoal powder into a strong element to improve the diamond holding force . Diamond saw blade process , if there is a good tip carcass holding force on the diamond, diamond blade is a good , not too early fall , when cutting sharp , high efficiency. Usually the surface by plating a layer of diamond strong carbon compound , a metal element , such as plating, titanium, chromium, nickel, tungsten, etc., in order to improve the bonding of diamond powder with the matrix and help prevent oxidation and high temperature sintering the diamond graphitization ; matrix powder can also add a small amount of strong elements of carbon powder , such as: molybdenum, chromium, tungsten powder. Since this type of powder gold , diamond and pro- wetting force is better, when sintered diamond and matrix metal surface to form carbide alloys , diamond and matrix metal in favor of chemical bonding and metallurgical bonding , thus greatly improving the carcass of diamond holding force .

    3 , to improve the diamond size ratio . Traditional ratio, sharp blade to more, spend more coarse diamond , and vice versa with a fine diamond . Admittedly , such as , but always less than optimal efficiency. Since the hardness and elastic modulus of the diamond high surgery , plastic deformation hardly occurs when the high temperature sintering . Selected ratio, improved bulk density before sintering diamond particles , to improve the tool wear than favorable . After several experiments draw general head coarse , coarse, fine diamond particles composed of three kinds , the optimal particle size ratio 1:0.0227:0.071 .

    4 , the use of ultra-fine powder pre-alloyed powder. Ultra-fine powder helps reduce the sintering temperature, increase matrix hardness . And the pre- alloy powder , through the three-dimensional mixing, greatly reducing the contact time of the powder and the air , to prevent premature loss of the low melting point metal segregation and help to improve the strength of sintered products , increasing the gripping force of the diamond .

    5 , add the appropriate amount of matrix powder rare earth elements ( such as lanthanum , cerium , etc. ) . Can significantly reduce the wear performance bond to improve diamond saw cutting efficiency.

    6, using a hot cold sintering , vacuum sintering protective atmosphere . By cold pressing and sintering after a very sharp blade sawing process performance , productivity increased a lot, and vacuum sintering protective atmosphere to prevent oxidation of the powder , activated sintering , both to improve the performance of the head , and extend the life of the graphite mold , but also lower production costs

    7 , the correct welding technology, nowadays Diamond Park saw both high frequency welder to weld , the welding head prone second " burn " off the head phenomenon . Not only unsafe , and the impact on production , and therefore should be made of high strength , good permeability silver solder pieces for welding processing.

    Based on the above points , a high quality and efficient diamond saw that successfully developed . However, the use of diamond tool production process , the tool affected by many factors , have "because of the stone ," depending on the stone texture, different sawing machine and adjust , reasonable choice and the proper use of the saw blade , saw blade performance into full play, so as to get a good results.
