Below, specify the mode that is used for embodiment of the present invention based on accompanying drawing.Like Fig. 1, shown in Figure 2, are throws according to the throw 10 of the 1st embodiment of the present invention with inverted V-shaped sheet 11 (11a, 11b), on the periphery of discoideus rotary body (base member) 12 along the circumferential direction with the jagged sword platform 13 of equidistant formation.This sword platform 13 forms the front and sees the word of falling V shape, and to form incised notch in the direction of rotation face side of this sword platform 13 be that the side sees that carrying of L type put portion 14, puts affixed inverted V-shaped sheet 11 (11a, 11b) in the portion 14 in this year.Inverted V-shaped sheet 11 has polycrystalline diamond layer (PCD layer) 16 in the face side of hard alloy layer 15, PCD layer 16 is carried to put carrying towards direction of rotation face side (rake side) put in the portion 14 and weld affixed through silver solder etc.
Inverted V-shaped sheet 11 along the circumferential direction alternately disposes the 1st inverted V-shaped sheet 11a and the 2nd inverted V-shaped sheet 11b and they is fixed on the sword platform 13 of throw; The 1st inverted V-shaped sheet 11a has lead angle δ in right bank sword (an inclination sword) the 17a side that constitutes sharp sword (sharp I
), and the 2nd inverted V-shaped sheet 11b has lead angle δ (Fig. 3) in left bank sword (another inclination sword) the 18a side that constitutes sharp sword.
In the 1st inverted V-shaped sheet 11a (Fig. 2 (a)), the angle of inclination K2 that the left bank that formation is dodged sword is dodged the center line Y that sword (sword is dodged in another inclination) 17b hangs down with respect to the front end (upper end) from blade tip forms forr a short time than the angle of inclination K1 of right bank sword (an inclination sword) 17a that constitutes sharp sword.
On the other hand, the 2nd inverted V-shaped sheet 11b (Fig. 2 (b)) sees from the front and forms with respect to center line Y and the 1st inverted V-shaped sheet 11a left-right symmetric.Promptly; In the 2nd inverted V-shaped sheet 11b, the angle of inclination K2 that the right bank that formation is dodged sword is dodged the center line Y that sword (sword is dodged in an inclination) 18b hangs down with respect to the front end (upper end) from blade tip forms forr a short time than the angle of inclination K1 of left bank sword (another inclination sword) 18a that constitutes sharp sword.
Particularly, be under 45 ° the situation in the angle of V groove, in the 1st inverted V-shaped sheet 11a, the angle of inclination K1 of the right bank sword 17a that constitutes sharp sword is made as 22.5 ° with respect to center line Y, the angle of inclination K2 that left bank is dodged sword 17b is made as 22～14 °.On the other hand, in the 2nd inverted V-shaped sheet 11b, the angle of inclination K1 of the left bank sword 18a that constitutes sharp sword is made as 22.5 ° with respect to center line Y, the angle of inclination K2 that right bank is dodged sword 18b is made as 22～14 °.The angle of inclination K2 dodge sword 17b, 18b if tilt compares too small with the angle of inclination K1 of inclination sword 17a, 18a, then rigidity descends.On the other hand, if difference is too small, then be easy to generate burr.
Lead angle δ among the 1st inverted V-shaped sheet 11a and the 2nd inverted V-shaped sheet 11b is made as 10～20 ° respectively.If enumerate an example of other sizes, then the diameter of throw 10 is 120mm, and the thickness T of base member 12 is 2mm; The blade number is 6～30; The width T1 of sheet is 1.5～2mm, and anterior angle α is 10～20 °, and periphery cutting edge oblique angle (escaping the げ angle) is 5～10 °; Cutting edge oblique angle, side is 5～10 °, and the width B of front end cutting edge is 0.02～0.1mm.In addition, the above-mentioned example that is of a size of can suitably change according to purposes certainly.
In the past, in the inverted V-shaped sheet in processing of V groove or the incisory throw of V, we can say and do not consider to be provided with helical pitch.Its reason is and since front end be the depth as shallow of acute angle, the processing of V groove or V cutting to for about 1.5mm, so even helical pitch is set, also less by the effect of its generation, on the other hand, be used to be provided with the processing trouble of helical pitch etc.
With respect to this; On each inverted V-shaped sheet, lead angle is set in the present invention; And the angle of inclination of inclination being dodged sword forms forr a short time than the angle of inclination of the inclination sword that constitutes sharp sword; And alternately dispose each inverted V-shaped sheet, so when alleviating cutting resistance, substrate can not produce burr ground by cutting tartly in the sharp sword side of an inverted V-shaped sheet.Though in residual of the cutting of dodging the sword side, be easy to generate burr, the sharp sword through ensuing another inverted V-shaped sheet cut residual quilt and cuts tartly, and burr is removed, and can realize that carrot-free V groove processes.
