Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: a ball end mill for machining a blade disc comprises a cutter body 1.

Further, a rear thread groove 10 is formed at the left end of the cutter body 1, and the cutter body 1 is connected with the milling machine spindle through the rear thread groove 10.

Anti-skidding recess 2 has been seted up to the upper end of cutter body 1, and fixed slot 3 has been seted up to the right-hand member of cutter body 1, and the shape of fixed slot 3 is the polygon, and the right-hand member fixedly connected with of cutter body 1 prevents interfering ladder 4, and prevents interfering ladder 4's centre and offer the opening the same with fixed slot 3 shape, fixedly connected with anticollision layer 5 in the fixed slot 3.
