FIELD: process engineering. ^ SUBSTANCE: proposed tool comprises cutting head extending along rotational axis and having several main cutting edges extending radially outward, each terminating on cutting head circumference by cutting angle with angular chamfer. To increase durability of tool and decrease burrs, angular chamfers on cutting angle of appropriate main cutting edge differ, namely, both roughing and finishing chamfers. Note here that roughing chamber is larger than that of finishing. ^ EFFECT: higher quality reduced burring. ^ 10 cl, 6 dwg |
