DEVICE FOR VIBRATION NEEDLE HOBBING

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to machine building and may be used for deflashing, chamfering and planar machining at milling, multiposition and hybrid machine tools. Proposed device comprises case with its bottom to be secured to machine table and its top to support billets to be machined. Round plate is fitted on said washer by flexible and rigid rings and provided with dead hole to receive rotor journal to run in bearing. Said journal is offset relative to main journals. The latter run in bearings of rotary air engine rotor. Stator is arranged at case center and provided with chamber to feed compressed air acting on rotor vanes. ^ EFFECT: expanded operating performances, higher quality and efficiency, reduced costs. ^ 13 dwg
