The precise polished grinding tool of class is that the abrasive material with sanding and polishing function is combined with polymer base material, as inventor has applied
Application for a patent for invention（Publication No. CN105313033A）Disclose a kind of elastic TPU polishing composite membrane, the technical scheme be by
Abrasive material is bonded to TPU base materials and is made, due to the flexible excellent characteristic such as good, flexible, environment-protecting and non-poisonous of TPU base materials so that
Turn into the polishing abrasive tool with excellent flexibility and elasticity after abrasive material and TPU are compound.However, although TPU base materials improve throwing
The elasticity and flexibility of tarry matter tool, but its mechanical strength, high temperature resistant, friction resistant performance is insufficient, wants to make polishing abrasive tool simultaneous
Has function above, inventor attempts several high polymer materials with function above being combined with each other, but tests and find, right
In TPU and other variety classes high polymer materials, all it is very difficult to the flexible of cohesive high polymer material, particularly TPU
Property is larger so that the adhesion difficulty between TPU and other high polymer materials is very big, so as to cause it is compound after polymer base material
Performance is unstable, can not meet the requirement of high precision polishing.This is exactly difficult to the key technology overcome at present；It is in addition, existing
Polishing abrasive tool, due to the adhesion deficiency between abrasive material and base material, there is the phenomenon that sand grains comes off, and grindstone dust during polishing
Coalescence occurs and causes the phenomenon blocked, the quality dissatisfactions such as cut occurs in the surface of product after polishing, grinding tool makes so as to cause
The problem of with short life, therefore, existing polishing abrasive tool, can not meet the needs of in irregular shape or curved surface etc. is precise polished.
