Especially the attrition between work object, the tool in the attrition aspect's life has not advantageous theory according to,The drop of the working efficiency because of the attrition has not a accurate estimation plan,this will cause the machine run in low mechanical efficiency long time,we need develop a estimation research about attrition.to accurately estimation attrition in the different material, expresses this kind of influence through certain parameter , We may through the concrete value estimate that the specific material the mechanical property which displays under the specific abrasion environment. From this we may estimate machinery's working life, may carry on the control in the new machinery's design process of manufacture to machinery's life, may know ahead of time the machinery later will present the low working efficiency movement, may before this condition appears replaces the influence efficiency the working part, guarantees the production efficiency. Key words: attrition; estimation; life; production efficiency II
