CUTTER WITH A REPLACEABLE RESHARPENED PLATE Russian patent published in 1995 - IPC

FIELD: material mechanical machining. SUBSTANCE: bearing surface of the plate and the holders are not made smooth but they have riffles. The lateral bearing surface is located at an angle to the riffles and to the main cutting edge. During the regrinding the plate is moved for one step. In this case the plate geometry is preserved at the expense of the slanted chip-breaking flute. EFFECT: substitution of a tool with a non-resharpened plate for the analogous tool with a replaceable resharpened plate. 2 cl, 3 dwg
