MODE OF COMBINED NEEDLE-MILLING CUTTING Russian patent published in 2007 - IPC B23C3/00 

FIELD: the invention refers to the technology of machine building, to metal processing by cutting.

SUBSTANCE: the mode is in that a needle-milling cutter has a body having freely placed buckets with a bundle of pile is given a rotary motion and a longitudinal feed. For expansion of technological possibilities due to controlling the depth of the removable layer and the microrelief of the finished surface they by turns impart rigidly on work surface with installed bundles of pile and with bundles of pile mobile in radial direction displacing under the impart of shocking pulse loading. The body is rigidly fixed on a spindle and is fulfilled in the shape of a disk with radially located sockets in which there are buckets mobile in radial direction. At that the needle-milling cutter is provided with an unmovable support contacting with the bottom of a mobile bucket and with unmovable buckets with bundles of pile interleaved with mobile buckets rigidly fixed in the longitudinal grooves of the body having in transversal section a form of trapeze expanding to the center. They are fixed with the aid of a wedge. At that the unmovable buckets have a form reciprocal to the form of the groove.

EFFECT: expands technological possibilities of the needle-milling cutter.
