METHOD OF PULSED NEEDLE MILLING OF SURFACES Russian patent published in 2009 - IPC B24B39/00 

FIELD: process engineering.

SUBSTANCE: device comprising casing with wire frieze bundles gets rotation and lengthwise feed. Processed workpiece receives reciprocation. Proposed device creates additional interference. Device casing represents a plate with radial slots arranged on its end face to accommodate the plates with cutting elements representing aforesaid bundles of wire frieze. The latter represent bent metal wires with their one end rigidly attached perpendicular to the plate plane and their other end attached to waveguides the latter represent stepwise cylinders arranged in the guides of the casing peripheral lengthwise bores. The waveguide other ends are in contact with cams to create pulses lengthwise load onto bundles of wire frieze overcoming spring resistance. Aforesaid cams are arranged on fixed ring to allow waveguide lengthwise overhang.

EFFECT: expanded performances, higher efficiency, lower costs.
