Analysis Of High Quality Technical Solutions Developed By Diamond Saw
With Decorative Materials Market development, Stone Demand is greatly increased, in Stone Processing, diamond tools, the growing demand. However, the present Yunfu quality diamond saw blade on the market is not ideal. Often start very sharp, cutting edge to the half diamond out of a bad, off severely, or cutting a small number, a number of working hours for the first blade, resulting in processing efficiency is not high.
Stone enterprise demand for high quality, cost-effective good diamond saw blade.
For the status quo, after repeated practice, a set of production efficiency, high-quality technical program of diamond saw blade come out.
1, with production of stable, coarse grain, good thermal stability (ti and tfi directly near) the high strength of diamond. Diamond tool is essentially a diamond with the matrix under certain conditions was fixed to the substrate, mainly by diamond grinding agent to process the role of different stone cutting. Therefore, the raw material (diamond) the quality, size and concentration on the diamond tool has a decisive role.
2, although the carbon powder into the strong elements, improve the diamond holding force. Processing in the diamond saw blade, diamond segment matrix if there is a good holding force, Diamond will be a good blade will not fall off prematurely, cutting sharp and efficient. Generally surface coated by a layer of strong diamond carbon compounds to form metals, such as plating, titanium, chromium, nickel, tungsten, to enhance the diamond powder with the matrix bonding, and helps prevent high temperature sintering of diamond oxide and graphite; also available through the matrix powder, add a small amount of carbon powder strong elements, such as: molybdenum, chromium, tungsten powder. As such powder of gold, diamond and the affinity of the wettability of better sintering of metal matrix in diamond and charcoal alloy surface is conducive to diamond and the chemical bonding and metal matrix Metallurgy Combine to greatly enhance the holding force matrix on the diamond.
3, improve the diamond’s size ratio. Traditional ratio, the blade should be sharp more, spend more coarse-grained diamond, and vice versa with the fine diamond. Indeed so, but always reach the best efficiency. As the diamond hardness and elastic modulus of high technique, high temperature sintering is difficult to occur in the plastic deformation. Selected ratio before sintering diamond particles to improve packing density, to improve the tool wear ratio is favorable. After several experiments obtained the general head coarse, coarse, fine diamond particles composed of three, the best size ratio 1:0.0227:0.071.
4, use of superfine powder and pre-alloy powder. Ultrafine powder helps reduce the sintering temperature, increased matrix hardness. The pre-alloy powder, through the three-dimensional mixing, greatly reducing the powder and the air contact time, to prevent premature loss and segregation of low melting point metal, and help to improve the strength of sintered products, increase the holding force on the diamond.
5, add the appropriate amount in the matrix powder rare earth elements (such as lanthanum, cerium, etc.). Can significantly reduce the wear performance bond to improve the efficiency of diamond saw cutting.
6, with a hot cold sintering process, sintering atmosphere, vacuum protection. Carried out by cold pressing and then sintering the segment performance in the cutting process is very sharp, a lot of production efficiency, while protecting the atmosphere of vacuum powder sintering prevents oxidation, activated sintering, both to improve the blade performance, but also extended the graphite mold life and reducing production costs.
7, the correct welding process, nowadays diamond saw blades are high frequency welding machine park to welding, welding prone segment of the second “burn” and heads out the phenomenon. Not only unsafe, and the impact of production and should therefore be high strength, good permeability of silver solder pieces to be welded processing.
The above points, a high quality and efficiency of the diamond saw blade that is developed. However, the production of diamond tools used in the process, many factors that affect the tool, must “for stone” stone under different texture, different cutting machine and adjust, reasonable choices and proper use of the saw blade, saw blade performance to be give full play to get a good use of effects.
