Tool life and wear rate on

Tool life refers to the so-called post-sharpening cutting tool from the beginning to achieve blunt standards, the use of cutting time. The wear limit is determined, tool life and  cubic boron nitride . Wear the slower the speed, the higher durability, so any impact tool wear factors must affect tool life. Tool life and cutting tool is a measure of an important  abrasive grinding  of good or bad. So we have to analyze the factors that affect tool life, which effectively controls the relationship between these factors in order to obtain a reasonable tool life, the tool has good machinability.
