COATED ABRASIVE TOOL Russian patent published in 2016 - IPC B24D3/28 

FIELD: metal processing.

SUBSTANCE: invention relates to abrasive treatment. Abrasive article consists of a flexible substrate having a base surface, containing the elastic polymer capable of elastic extension and transversal compression, the strip of elastic polymer is 5.1 cm wide, 30.5 cm long and 0.102 mm thick, elongation in longitudinal direction at least 3 % at 22.2 N static load; synthetic resin, in contact with the base surface and spread over all the base surface by preset pattern of the surface discrete zones, abrasive particles in contact with synthetic resin and as a whole in combination with it, and adhesive resin in contact with abrasive particles, as well as synthetic resin, adhesive resin is in combination with abrasive particles and also with synthetic resin, whereas the areas of the base surface in contact with synthetic resin, in general are located in one plane with areas of the base surface not in contact with the synthetic resin.

EFFECT: technical result: abrasive article has excellent torsion, segregation, and load resistance, higher flexibility and lower materials-output ratio compared to common abrasive articles.
