How to Extend Tungsten Carbide Tool Life
Optimize Cutting Parameters: Use appropriate speed, feed, and depth of cut for the material being processed. Excessive speed or load can accelerate wear and cause premature failure.
Use Proper Cooling and Lubrication: Apply sufficient coolant or cutting fluids to reduce heat generation and friction, which helps prevent thermal cracks and prolongs tool life.
