Diamond tools and CBN inserts Manufacturers

For improving the caliber of diamond tools, we currently know 6 effective ways:

1. Adopt high hardness diamonds inside the diamond tools manufacture.

Diamond's quality, grit and concentration play decisive roles during the diamond tools' quality. There are already many famous diamond brands on earth. 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 both in quality and value worldwide market. So manufacturers have a very more great choice.

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

A good hold to diamonds will result in the diamonds not to ever fall off in the diamond tools early. Also, this will also make the diamonds have the good protrusion height, and so the diamond tools is going to be sharper and more durable.

Plating the diamonds with a bit of metal elements, for example Cr, Ni, Ti, W, etc., that will result in the formation of carbide, is a great way to enhance the diamond wire rope hold to diamonds. This is mainly for three reasons. First, the plated metals can prevent the diamonds' oxidation, graphitization as well as the hot corrosion of Fe element under a certain temperature, pressure along with the time of sintering. Second, the plated metals can form carbide alloy in the interface between your diamonds and the tool's bond inside the sintering. This will likely do much assist to the chemical bonding and metallurgical combining in the diamonds plus the metals in tool's bond. Third, after plated by using these metals, the diamonds' friction is improved.

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

Ultrafine powder enables you to limit the temperature of sintering, and improve 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, improve the tools' hold to diamonds, lessen the temperature of sintering, and lower the amount of time of heat preservation.

4. Use good granulation technique in producing segments.

Good granulation technologies will reduce the segregation of diamonds, distribute the diamonds more evenly, improve the cutting performance of segments, improve the mobility of the powder, help the cold pressing technique, and lower the dust hazards to workers.

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

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

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

Hot Isostatic Press (HIP) can decrease the porosity of the products, and boost the beads' density, hardness, toughness and gratifaction.

High temperature brazing will make the beads have: a fair diamonds distribution, chemical bonding and metallurgy combination, a formidable hold to diamonds, and good diamonds' protrusion heights. By applying this system, using diamonds helps you to save half, the cutting speed is going to be 2 to 4 days of the normal once the useful every day life is equal, plus the production costs will be lowered.
