PURPOSE:To have precision grinding of the rake face and flank of a cutting edge simultaneously in a single stage in processing, by using a disc-shaped brush wheel, which is constituted with brushes including grinder element as a honing tool. CONSTITUTION:When a brush wheel rotates, the tip of a brush filament 5 is put in contact from the rake face 2 side, and the filament 5 deflects for abrasion of the tip of said rake face 2 with abrasive grains at the foremost part of filament. After passage of the foremost part, said deflection of the filament 5 returns to the straight state, so that the tip of filament 5 causes abrasion also at the flask 3 side while passing there. The filament 5 is provided with a smooth honing surface, which includes a number of abrasive grains so as to cause abrasion of the tip of cutting edge. In the case of a twisted cutter, the tangential line of the spiral curve at its portion for honing shall be in parallel with the wheel shaft, while in the case of a straight edge the straight line of the tip of cutting edge in parallel with the wheel shaft. Thereby manufacture of endmills can be provided in good efficiency and with high economical performance. |
