Diamond tools and CBN inserts Manufacturers

diamond tools and cbn inserts Diamond's quality, grit and concentration play decisive roles within the diamond tools' quality.

There are already many famous diamond brands on the planet. In August 2007, 20/30 big grit high hardness diamonds which had been produced with China's hinged cubic press machine successfully passed technical identification. These kind of diamonds have advantages in quality and cost in the world market. So manufacturers use a more good choice.

2. Plate some metal elements for the high formation of carbide on diamonds to increase the tools' hold on the diamonds.

An effective hold to diamonds can cause the diamonds not to ever fall off in the diamond tools early. Additionally, this will likely also create the diamonds possess the good protrusion height, and for that reason the diamond tools is going to be sharper and a lot more durable.

Plating the diamonds with many metal elements, one example is Cr, Ni, Ti, W, etc., which can make the formation of carbide, is a good way to increase the diamond grinding disc hold to diamonds. This is certainly mainly for 3 reasons. First, the plated metals can stop the diamonds' oxidation, graphitization and the hot corrosion of Fe element beneath a certain temperature, pressure as well as the period of sintering. Second, the plated metals can form carbide alloy for the interface between diamonds along with the tool's bond inside the sintering. This will likely do much help you to the chemical bonding and metallurgical combining from the diamonds and the metals in tool's bond. Third, after plated with all of these metals, the diamonds' friction is improved.

3. Use ultrafine powder and pre-alloyed powder in the tools' bond.

Ultrafine powder enables you to lessen the temperature of sintering, and increase the hardness.

Pre-alloyed powder can prevent metals of low melting point from losing and segregating, benefit the elastic limit and yield strength of sintered products, raise the tools' hold to diamonds, lessen the temperature of sintering, reducing the time of warmth preservation.

4. Use good granulation technique in the production of segments.

Good granulation technologies will decrease the segregation of diamonds, distribute the diamonds more evenly, strengthen the cutting performance of segments, enhance the mobility with the powder, benefit the cold pressing technique, reducing the dust hazards to workers.

5. Take advantage of the vacuum protection atmosphere hot pressing technique and equipments within the sintering process.

Sintering is a key technique in the diamond saw blades' manufacture. It is going to have an impact on the saw blades' segment density, hardness, cutting performance, technical performance in the sintering equipments, production costs, and product quality.

6. Apply Hot Isostatic Press (HIP) and high temperature brazing technique during the output of diamond wire saws.

Hot Isostatic Press (HIP) can lower the porosity with the products, and increase the beads' density, hardness, toughness and gratification.

High temperature brazing will make the beads have: an acceptable diamonds distribution, chemical bonding and metallurgy combination, a robust hold to diamonds, and good diamonds' protrusion heights. By using this procedure, the utilization of diamonds will save half, the cutting speed is going to be 2 to 4 times of the normal when the useful life is equal, and the production costs are going to be lowered.
