Abstract

PURPOSE: To obtain tools applied for hard to cutting material capable of milling by a method wherein a side edge having an angle of relief on the outer periphery and a cutting lip having a point angle of a specific value are provided on a body having the ratio of an outer diameter to a core thickness which exceeds a specific value and a plurality of surfaces of relief having angles of relief of respective specific values are provided on the cutting lips.
CONSTITUTION: Side edges 16 having a desired angle α of relief on the outer periphery are provided on a body 15 having a ratio of 40 or more % of the outer diameter to the core thickness and cutting lips 19 having point angles 130W160° are provided on the point part of the tool body 15. The corner parts 17 take obtuse angles by θ and the strength of the cutting edges of these parts can be improved. A rake surfaces 18 is provided on the side edge 16, further the 1st, the 2nd surface of relief 10, 11 are provided respectively on the cutting lips 19 and the angles of relief of these surfaces 10, 11, though they differ by the diameter of the tool body 15, are preferred to take respectively 3W10° and 30W65° to surfaces rectangular to the central axis of the body 15. Flat surfaces 12 are generated on the surfaces 18 of rake at the vicinity of the cutting lips 19 in order to straighten the cutting lips 19 linearly. For the purpose of the shape of the cutter point, thinning is conducted to generate the cutting edge 13 of the central part.
