HELICAL CUTTER MILL Russian patent published in 2017 - IPC B23C5/04 

FIELD: machine engineering.

SUBSTANCE: cutter comprises at least one linear cutter attached to the outer peripheral surface of the circular body. The incisors are arranged at predetermined intervals in the circumferential direction on the outer peripheral circumference and are inclined by a predetermined angle α A helical line from a straight line on an outer peripheral surface parallel to the central axis of rotation. The surfaces for attaching cutters are tilted at an angle equal to the corner and on the main front corner β towards the elevation of tangent to the exterior surface of the peripheral and formed stage, arising from the tilt in the direction of the angle of elevation. Each cutter is secured detachably by means of the holder. Cutter fastening portion has L-shaped cross-section obtained at the expense of the environment of its surface for attachment and the tool stage. Provides high economic and operational characteristics due to the minimization of the economic losses caused by damage to the cutter.

EFFECT: simplified mounting and replacement of the cutter.
