VIBRATION HONER Russian patent published in 2012 - 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. Proposed device comprises body and hone holders accommodating diamond external abrasive hones. Sleeve-like body is rigidly fixed on spindle mandrel and provided with bored cylindrical holes arranged along its periphery to accommodate reciprocating plungers. Every plunger is equipped with pivot arranged at its center to support rocker with coil compression springs to create radial operating pressure of hone holder on 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 are orifices provided to release compressed air into atmosphere and compression spring is arranged at cylinder bottom. Plunger goes down unless cylinder cross section is aligned with said orifice and is forced up by compressed spring. Plunger vibration frequency is controlled by pulley rpm.

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