Document Type and Number:
Japanese Patent JP3200665
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cutter structure wherein good durable film can be formed by a physical deposition on side relief faces in the neighborhood of valley bottoms in projected cutter blades or on outer diameter relief faces of bottom cutter blades without making a sacrifice of strength.
SOLUTION: In a milling cutter for slotting wherein a cutter body 22 comb- likely arranged with a plurality of projected cutter blades 24 are mounted on the peripheral direction of a cutter main body by a specified pitch and a bottom cutter blade is formed on the same face as the rake face 28 of the projected cutter blade on the valley bottom between the projected cutter blade 24 and an adjoining projected cutter blades, a bottom groove 38 with a width of 90-100% of the width of the bottom cutter blade is formed so as to cut the bottom cutter blade and then, the cutter body 22 is coated with a hard film. In addition, in this milling cutter for slotting the bottom groove 38 with a width of 70-100% of the width of this bottom cutter blade is formed by a press angle of 0-105° so as to cut the bottom cutter blade and then, the cutter body 22 is coated with a hard film.
