METHOD OF BURNISHING Russian patent published in 2013 - IPC B24B39/02

Abstract RU 2475348 C1

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, namely, to mandrelling. Part hole and mandrel surfaces are lubed. Mandrel is pushed through part deformable hole. Mandrel is used with taper lead and inverse cone and gaging working surface with regular micro relief to allow continuous lubing of plastic deformation. Lubrication material represents machine oil with addition of 20%-copper-bearing additive that features antiwear, antioxidant and oil-soluble properties to form servovite metal-plating films in plastic strain zone.

EFFECT: higher wear resistance and decreased mandrelling force.
