Tips For Improving the Quality of Diamond Tools
To improve the quality of diamond tools, we now know, 7 effective ways:
1. Adoption produce high hardness of diamonds in diamond tools.
Diamond's quality, grain size and concentration play key role in the quality of diamond tools. "There are already many famous diamond brands in the world. In August 2007, K 20/30 high hardness, large diamonds, which was produced with folding cubic China's press machine successful technical identification. This kind of diamondBenefits in quality and price on the world market. So manufacturers have a good choice.
2. Plate some metal elements for the formation of high carbide think diamonds you the tools "to improve the diamond.
A good hold for a diamond is the diamond lead does not fall too early in the diamond tools. Moreover, this is also the diamonds have good height advantage, and thus the diamond tools are sharper and more durable.
Support of Diamondswith some metal elements such as Cr, Ni, Ti, W, etc., which will cause the formation of carbide, is a good way to include the diamond tools "to improve diamond. This is especially for three reasons. First, the oxidation of metals can be plated diamonds ", graphitization and the hot corrosion of Fe-preventing element at a given temperature, pressure and time of sintering. Secondly, the metal can be plated alloy carbide at the interface between the diamond and the tool of borrowing in theSintering. This will contribute much to the chemical bonding and metallurgical connection between the diamond and the metal bond tool. Third, after plated with these metals, friction of Diamonds "will be improved.
3. Use ultra-fine powder and alloy powder in bonds of the tools.
Ultrafine powder helps to reduce the sintering temperature, and increase the hardness. Pre-alloyed powders can be metals with low melting point of loss and separation, to benefit the elastic limit and preventTo raise the yield strength of sintered products hold you reduce the tools "to reduce diamonds, the sintering temperature and time, the conservation of heat.
4. Use good granulation technique in the production of segments.
Good granulation technology is the separation of diamonds, the diamonds cut to distribute more evenly, to improve the cutting performance of the segments, the mobility of the powder to benefit the cold pressing technique and to reduce dust hazards toWorkers.
5. Use to protect the vacuum hot pressing atmosphere and facilities in the sintering process.
Sintering is a key technology in the manufacture of diamond saw blades. It will also impact on the saw blade segment, "density, hardness, cutting efficiency, technical capacity of the sinter plants, production costs and product quality.
6. Apply Hot Isostatic Press (HIP) and high-temperature soldering in the manufacture of diamondSaws.
Hot Isostatic Press (HIP) can reduce the porosity of the products, and to improve the density of the beads, hardness, toughness and performance.
High temperature brazing will have the pearls keep a proper allocation diamonds, chemical bonding and metal combination, a strong will to diamonds and diamond head start "heights. By applying this technique, the use of diamonds half is saved, the cutting speed 2 to 4 times the ordinary, when the utilizationequal, and the production costs.
7. Use of laser welding technology.
Laser welding machines can improve the quality of welding. They are characterized by great power, less gas consumption, low operating costs, less maintenance, reliability, quality of the beam, etc. With the laser welding, fixing the way the body of the saw blade and its segments from the "manual" last mode in the automatic mode, which is an accurate and reliable.
