FIELD: machine building.
SUBSTANCE: it is fed on treated surface hydroabrasive suspension. In the capacity of abrasive of hydroabrasive suspension there are used fine-dispersed particles with hardness on the Mohs scale 8÷9. Fine-dispersed particles allows dimension from 50 up to 80 mcm. Jet pressure of compressed gas, providing feeding of hydroabrasive suspension, is held in the following range: more or equal to 3.0 bar and less than 3.5 bar.
EFFECT: there are completely removed residues of grease lubricant and different pollutions from surfaces of products, it is provided required roughness of treated surface and increases processing speed.
