1. selection of diamond size
Single grain when the diamond grit size coarse and degree, saw blades sharp, high cutting efficiency, caking flexural strength of diamond when Diamond fine particle size or thickness, particle size mixed, saw blade cutter high durability, but are less efficient. Considering the above factors, 50/60 mesh select diamond size is more appropriate. Selection of diamond grit size diamond coarse granularity and when a single particle, saw blades sharp, high cutting efficiency, caking flexural strength of diamond when Diamond fine particle size or thickness, particle size mixed, saw blade cutter high durability, but are less efficient. Considering the above factors, 50/60 mesh select diamond size is more appropriate.

2. Diamond distribution of concentration of
In a certain range, diamond concentration changes from low to high, the sharpness of the blade and cutting efficiency decreased, and life is gradually extended, but concentration is too high, saw blade blunt. Using low concentration, coarse-grained, efficiency is improved. Head parts using knife when cutting the different roles with different concentrations (the middle tier in a three-layer or multi-layer structure using low concentration), saw blade cutters in the process forming the Middle Groove on to prevent blade runout, so as to improve the quality of stone processing.

3. selection of diamond strength
Strength of diamond cutting is an important indicator of performance. High strength makes crystal breakage, abrasive used is polished, sharp decline, resulting in performance deterioration of diamond strength is not enough, easily broken after the hit, it is difficult to take the cutting task. Strength should be chosen in 130~140N.

4. Binder choices
Saw blade performance does not only depend on the diamond, but depends on the diamond and adhesive appropriate tie heads consisting of the overall performance of the composite. For soft stone such as marble, demanding heads relatively low mechanical properties of some, the choice of bonding agent based on copper. But the low sintering temperature of copper-based Binder, strength, hardness and high toughness, low adhesive strength of diamond. When joining tungsten carbide (WC), WC or W2C as a skeleton of metal, coupled with the right amount of cobalt in order to increase strength, hardness, and binding properties, and adding a small amount of low melting point, hardness and low Cu, Sn, Zn metal binding phase. Principal and component size should be fine to 200 mesh, adding 300 components particle size should be fine.

5. selection of sintering technology
As the temperature rises, matrix densification increased flexural strength also improved, but with the extension of time, bending strength of blank matrix and diamond lumps first increased and then decreased, choose 800 ℃ 120s sintering process to meet the performance requirements.
