Cutting device for use in cutting machine to cut parts, has blade holder whose clamping surface is tilted with respect to bearing surface at open acute angle toward slot, where blade holder includes bearing surface forming support plane

摘要

The device has a rotary tool holder (1) formed of an annular or cylindrical hollow cylindrical body. The body comprises an external peripheral notch. Blade holders (2, 3) include a bearing surface (262) forming a support plane on a bottom of the notch to allow displacement by slipping the blade holder in connection direction of a side (180) of the notch of the blade holder by a reception slot for reception of a blade (4). A clamping surface of the blade holder is tilted with respect to the bearing surface at an open acute angle toward the slot.
