Overheating during operation is the number one enemy of diamond tools. The excessive heat can weaken the bonding material that holds the diamond particles in place resulting to the cutting tip to lose shape or break off. A diamond tool may crack when exposed to temperatures above 700° Celsius.
A common cause for overheating is the insufficient amount of coolant used during operations. In order to ensure that the cooling system is working perfectly, frequent inspection and timely repair are needed. Other causes of overheating includes using improper speed configuration for the material. This problem is often evidenced by burn marks which indicates that the speed of the cutting tool is too great.
Knowing when to replace diamond blades is almost as important as preventing it from getting damaged. Using a worn out tool not only affects the quality of work but also puts in danger other part of the machine like the motor. Because the blades are not cutting as fast as it normally does, the operator will have the tendency to add more pressure than what is safe for the machine.
