Diamond tools production technology development in three stages

The first stage is to use elemental powder as matrix plus diamond production process using mechanical mixing diamond tools. This process prone to segregation component; sintering temperature is high, likely to cause graphitization of diamond, lowering of the strength of the diamond. Due to a variety of matrix materials are mechanical bonding, not fully alloyed carcass of the diamond package inserts poor, difficult to produce high-end products.

The second stage is the use of pre-alloy powder as mixing matrix plus diamond diamond tool production process. This process is due to be fully alloyed matrix material, the sintering temperature is low, the diamond will not reduce the strength, to avoid component segregation, diamond package inserts produce good results, the diamond function play very well. For carcass production with pre-alloy powder diamond tools, high efficiency has, slow decay characteristics that can produce high quality diamond tools.

The third stage is the use of pre-alloy powder as matrix, using a diamond ordered (multi-layer, uniform diamond) technology. This technology is a technology to accommodate a pre-alloy powder, in turn ordered arrangement of diamond, the diamond had to make full use of each piece, to overcome the mechanical mixing process caused by the uneven distribution of diamond cutting performance seriously affect the defect , is the world's production of diamond tools of the latest technology.

In the usual 350mm diamond cutting blades, for example, cut the first stage of the technical efficiency of 2.0m (100%), the cutting efficiency of the second phase of technology to 3.6m (up to 180 per cent), the third phase technology The cutting efficiency 5.5m (up to 275%) or more. The first phase of the technology in China's current production of diamond tools business, 90 percent still use less than 10% of companies use the second phase of the technology, few companies use third stage technology. It is not difficult to see that the current Chinese enterprises in the production of diamond tools, few enterprises are fully capable of producing high-quality products. However, most companies still using traditional, outdated technology.
