GENERAL RULES FOR DIAMOND BLADE PERFORMANCE....

Keep in mind.... Hard Bond for Soft Abrasive Materials Soft Bond for Hard Dense Materials

1. Increasing diamond concentration, reducing diamond size, increasing the cutting depth or blade width will make the blade act as if had a harder bond. This is caused by decreased load on the individual diamonds.

2. Increased bond hardness will make the blade act harder because the increase in the amount of resistance required to expose new diamond.

3. Higher R.P.M. on the blade will make it act harder. Due to the fact that the diamonds are not in contact with the material being cut as long.

4. Increasing the travel speed, faster feed rates, will make the blade act softer. Increased pressure on the diamonds cause them to be removed from the bond at a faster rate.

5. Increasing the horsepower will make the blade act softer. Increased pressure on the individial diamonds cause them to be removed from the bond at a faster rate.

6. Increased coolant volume will make the blade act harder. The coolant assists in the removal of the cuttings which reduces the amount of wear on the bond.

7. These rules are general and may not always apply to every application due to the number of variables in most cutting applications.
