Right angle profile, side shaping cutter tooth and top surface the shaping respective tail end of cutter tooth is equipped with what is radially extended along the cutter head
Corner is molded, the shaping corner is for the groove at shaping mobile phone shell inner wall fastening.
Specifically, the cutter head is set there are two side shaping cutter tooth and two top surfaces shaping cutters tooth, side shaping cutter tooth with
The circumferential direction of top surface shaping cutter tooth along the cutter head, which is stated, to be interspersed.
Specifically, axial first relief angle of side molding blade is a1,4 °≤a1≤6 °, side molding blade axial second after
Angle is a2,7 °≤a2≤9 °.
Specifically, axial first relief angle of top surface molding blade is b1,4 °≤b1≤6 °, top surface molding blade axial second after
Angle is b2,7 °≤b2≤9 °.
Specifically, the shaping corner has two profile sides, and the first profile side is laterally set, the second shaping
Angle between the axial direction of profile side and the side set forming cutter is C, 42 °≤C≤46 °.
The beneficial effects of the utility model are：
The inner end of top surface molding blade is located within the molding blade rotational trajectory face of side, and the inner end of side molding blade is located at top surface
Within molding blade rotational trajectory face.Side molding blade is with top surface molding blade for the right angle profile of shaping step jointly so that this
The compound side set forming cutter of utility model just can be processed the right angle profile of step, by one-pass so as to improve
Processing efficiency.In addition, the right angle profile is jointly molding by two cutting edges, the processing quality higher of right angle profile.Side
Shaping cutter tooth is equipped with the shaping corner radially extended along the cutter head with the top surface shaping respective tail end of cutter tooth so that this
The compound side set forming cutter of utility model, can be by the groove one at mobile phone shell inner wall fastening during right angle step is processed
And process and draw, so as to by a cutter, process two features, so as to save process, improve processing efficiency.

Specific embodiment
The utility model is further described With reference to embodiment.
See Fig. 1, compound side set forming cutter provided by the utility model, including cutter head, cutter head be equipped at least one side into
Type cutter tooth 1 and at least one top surface shaping cutter tooth 2.Side is molded cutter tooth 1 and is respectively provided with into top surface shaping 2 respective head end of cutter tooth
Type notch.The shaped notch of side shaping cutter tooth 1 has axially disposed side molding blade 11 (see Fig. 2, Fig. 3).Top surface into
The shaped notch of type cutter tooth 2 has the top surface molding blade 21 being disposed radially (see Fig. 4, Fig. 5).The inner end position of top surface molding blade 21
Within 11 rotational trajectory face of side molding blade, the inner end of side molding blade 11 be located at 21 rotational trajectory face of top surface molding blade with
