There are many factors influencing the cutting effect of diamond circular saw blades,there are two aspects the manufacturing and use factors. Manufacturing factors include raw materials, manufacturing processes (diamonds, binders, core blanks and formulars, hot pressing, welding, shaping), etc.; use factors refer to the choice of saw blade, the saw machinery, the selection of sawing parameters, and the installation of the saw blade. , operation, etc.

Diamond grit 30/35-60/70 is mostly used in blade. When cutting high abrasive material the grit should be coarse, cutting very hard,high density Granite and crisp glass, the grit should be fine.

1. the struture and size selection of saw blade:
The salesman is required to be familiar with the conventional structure, size, and maximum cutting depth  (which can be 1/3 of the diameter of the saw blade) of the circular saw blade of diameter ¢105-2200mm, and should be able to recommend a reasonable structure and size according to the processing conditions.
Table 1 is the circular saw blade size

(1) The Selection of core material:
     The core must have sufficient strength, rigidity and hardness. Genarally, the hardness of core requires HRC 35-42, the maximum surface roughness is Ra 3.2um; the surface may not have cracks, burrs, or rust; the core must be eliminate distrorted forces, micro-cracks, to ensure tensile stress balance, flatness and other shape requirments and appearance, internal quality requirements.
     At present , hot-pressed, high-frequency welding core material used high quality spring steel 65Mn, 50Mn2V, laser welding saw blade core use tempered steel 30CrMo, 35CrMo, because of its low carbon content, laser welding and the transition layer solder well.

Therefore, in addition to adjusting the diamond and the anchoring agent, it is necessary to increase cutting speed, enlarge cutting depth and decrease feeding for reducing the crush and shedding of the diamond, as well as the wear of the anchoring agent. This method can enhance cutting efficiency and prolong the lifespan. By contrast, when the diamond has excessive wear resistance, the stone will be ground into a flat or smooth arc surface, and it is hard to produce micro crushing, which means that the anchoring agent matrix is over wear-resistant or it has too much control of the diamond; the cutting depth of the saw blade is large; the feeding is small; the processed material is hard and fine;

Usually, the crush & impact resistance of good quality diamond is better, wearing out slowly and little broken when cutting, so it is very suitable used for cutting strong abrasiveness material like:sandstone, concrete pavement, bituminous pavement, refractory material. In the mean time, Diamond should easy plating,Coarse grit, low Concentration, the bond bond should be high abrasiveness with strong holding force for diamond; the lower grade diamond, cuz the rush & impact resistance is relatively worse,is suitable for cutting easy-cutting material, and the grit should be fine, concentration should be higher, bond should be softer.
