Diamond saw blade selection parameters standard profiles

Diamond saw bladeThe selection parameters of the standard profile:

1. diamond size selection

When coarse diamond size and single size, the saw blade sharp, high cutting efficiency, but agglomerated diamond drop bending strength; diamond distribution concentration of choice, within a certain range, when the diamond concentration changes from low to high When, sharpness and cutting efficiency of the blade is gradually decreased, while life gradually extended; diamond strength of selection, diamond cutting strength is to ensure that an important indicator of performance. Diamond cutting strength is to ensure that an important indicator of performance. High strength makes crystal is broken, when using abrasive polishing is lowered, sharpness, resulting in deterioration of the tool; diamond strength is not enough when, in the easily broken by the impact, it is difficult to assume the task of cutting; sintering process of selection, with the the temperature, the densification of the carcass of improved flexural strength also will increase, and with the holding time.

1. diamond size selection

When coarse diamond size and single size, the saw blade sharp, high cutting efficiency, but agglomerated diamond drop bending strength; when the diamond size fine or coarse grained mixed, Saw Blade high durability, but less efficient. Considering the above factors, the choice of diamond particle size of 50/60 mesh more appropriate.

2. The choice of the concentration of diamond distribution

Within a certain range, when the diamond concentration changes from low to high, sharpness and cutting efficiency of the blade gradually decreased, while gradually extend the service life; but the concentration is too high, the blade becomes blunt. The use of low concentrations of coarse-grained, efficiency will be increased. Using different effects at different parts of sawing heads, using different concentrations (i.e., three or more layer structure of the intermediate layer may be a lower concentration), the saw blade during work head recess formed in the middle, there are It helps prevent blade deflection, thus improving the quality of stone processing.

3. Selection of Diamond Strength

Diamond cutting strength is to ensure that an important indicator of performance. High strength makes crystal is broken, the grains in the use of polished, sharpness decreased, resulting in deterioration of the performance of the tool; diamond strength is not enough when, in the easily broken by the impact, it is difficult to assume the task of cutting. You should choose the strength of the 130 ~ 140N.

4. Select the binder phase

We saw not only depend on the performance of the diamond, but on the diamond and the binder with the overall performance of the proper configuration of the tip of such composites. For marble and other soft stone, the requirements of the mechanical properties of the tip is relatively low, the choice of copper-based binder. But copper-based binder low sintering temperature, strength, low hardness and high toughness, combined with low intensity diamond. When adding tungsten carbide (WC), with WC or W2C as a skeleton of metal, with the right amount of cobalt to improve strength, hardness and binding properties, and add a small amount of low melting point, low hardness of Cu, Sn, Zn and other metals for bonding phase. The main ingredient plus 200 mesh size should be fine to add ingredients to be finer than 300 mesh size.

5. The sintering process selection

With increasing temperature, densification carcass increased flexural strength also will increase, and with the holding time, after the blank matrix and diamond agglomerated bending strength reduced to improve, you can choose 120s sintering process at 800 ℃ to meet the performance requirements.
