PNEUMATIC GENERATOR OF OSCILLATIONS IN HONING Russian patent published in 2011 - IPC B24B33/08 B06B1/18 

FIELD: process engineering.

SUBSTANCE: invention relates to cutting of hard-to-process metals and may be used in finish diamond-abrasive machining, for example, honing of bores. Pneumatic generator comprises case rigidly fixed on spindle and diamond-abrasive bar holders arranged outside. Said case has holes bored in lengthwise direction along its periphery to accommodate spring-loaded plungers reciprocating therein. Every plunger has a hinge at its center with rocker supporting helical coil compression springs on its ends to load bar holder to machined surface. Plungers with rockers and bar holders are subjected to lengthwise vibrations by compressed air feed through manifold and channel in pulley hub into cylinder head section. There is a bore to release compressed air into atmosphere in plunger down travel. Also, plunger vibration frequency may be adjusted by pulley rpm.

EFFECT: higher precision, efficiency and quality, simplified design.
