PULSE TYPE NEEDLE MILLING CUTTER Russian patent published in 2007 - IPC B23C5/00 

FIELD: manufacturing processes in machine engineering, working materials by cutting.

SUBSTANCE: needle milling cutter includes body with seats having turnings on inner surfaces and lid. In each seat bushing with pile bundle is freely mounted. Bushing has on outer surface shoulder whose width is less than width of turning. In order to enlarge manufacturing possibilities due to controlling depth of cut-off layer and micro-relief of worked surface, body is rigidly mounted on spindle and it is made in the form of disc along radiuses of which seats having rectangular cross section with rounded angles are formed. Bushings have shape reciprocal to that of seat. Needle milling cutter is provided in addition with stationary support in the form of pipe arranged in the same axis as spindle and supporting cam engaged with bottom of bushing. On peripheral surface of disc ring with apertures for pipe bundles is mounted.

EFFECT: enlarged manufacturing possibilities of milling cutter.
