S -7- 201221322 [發明的效果] 依據本發明的第1態樣的旋轉工具，因爲第1倒V形 刀片、第2倒V形刀片皆設有導角，將各倒V形刀片的 傾斜刀端刃的傾斜角度比成爲切邊刃的傾斜切邊刃的傾斜 角度小地形成，將第1倒V形刀片及第2倒V形刀片在 圓周方向交互地配置，所以可減輕切削阻力，且在一方的 倒V形刀片的切邊刃側，基板是由銳角被尖銳地切削而不 會發生毛邊。在刀端刃側因爲切削殘部會殘留且爲鈍角而 容易發生毛邊，但是藉由沿續另一方的倒V形刀片的切邊 刃使該切削殘部被尖銳地切削而使毛邊被除去。因此，可 進行無毛邊的V溝加工。 依據本發明的第2態樣的旋轉工具，第1倒V形刀片 ，是各別設有與一方的傾斜切邊刃及另一方的傾斜刀端刃 的下端連續並加大傾斜角度的倒角刃，第2倒V形刀片， 因爲是與第1倒V形刀片正面視左右對稱地形成，所以第 1倒V形刀片及第2倒V形刀片的各倒角刃是成爲將被切 削的V溝的角部一邊形成倒角一邊削去。因此在V溝的 角部不易發生毛邊。且，因爲各倒角刃部是將被削材的基 板朝內方按壓，所以從上下兩側進行V溝加工時基板不會 上下晃動，使被V溝加工的殘部的板厚成爲一定，可獲得 局品質的製品。 依據本發明的第3態樣的旋轉工具，第1倒V形刀片 ’因爲設有與一方的傾斜切邊刃的下端連續並加大傾斜角 度的倒角刃，所以將基板從上下兩側對於端面進行V形切S -7 - 201221322 [Effects of the Invention] According to the rotary tool of the first aspect of the present invention, since the first inverted V-shaped blade and the second inverted V-shaped blade are each provided with a lead angle, the inclination of each inverted V-shaped blade is The inclination angle of the blade end edge is smaller than the inclination angle of the inclined cutting edge which is the edge cutting edge, and the first inverted V-shaped blade and the second inverted V-shaped blade are alternately arranged in the circumferential direction, so that the cutting resistance can be reduced. Further, on the side of the cutting edge of one of the inverted V-shaped blades, the substrate is sharply cut by an acute angle without burrs. The burr is likely to occur on the blade edge side because the cutting residue remains and is obtuse. However, the burr is sharply cut by the cutting edge of the other inverted V-shaped blade. Therefore, V-groove processing without burrs can be performed. According to the rotary tool of the second aspect of the present invention, the first inverted V-shaped blade is provided with a chamfer which is continuous with one of the inclined cutting edge and the lower end of the other inclined blade end edge and increases the inclination angle. The second inverted V-shaped blade is formed symmetrically with respect to the front side of the first inverted V-shaped blade, so that the chamfered edges of the first inverted V-shaped blade and the second inverted V-shaped blade are to be cut. The corners of the V groove are cut off while forming a chamfer. Therefore, burrs are less likely to occur at the corners of the V groove. Further, since each chamfering blade portion presses the substrate on which the material to be cut is inward, the substrate does not sway up and down when the V groove is processed from the upper and lower sides, and the thickness of the residual portion processed by the V groove is constant. Get a quality product. According to the rotary tool of the third aspect of the present invention, since the first inverted V-shaped blade is provided with a chamfering blade which is continuous with the lower end of one of the inclined cutting edges and which increases the inclination angle, the substrate is moved from the upper and lower sides.

Therefore, burrs are less likely to occur at the corners cut into a V shape. [Embodiment] Hereinafter, embodiments for carrying out the invention will be specifically described based on the drawings. As shown in Fig. 1 and Fig. 2, the rotary tool 10 according to the first embodiment of the present invention is a rotary tool having inverted V-shaped blades 11 (lla, lib), and a disk-shaped rotating body (pedestal) 12 The outer periphery of the saw blade-shaped blade table 13 is formed at equal intervals in the circumferential direction. The blade stage 13 is formed in a front-side inverted V shape, and a mounting portion 14 that is concavely cut into a side view type L is formed on the surface side in the rotation direction of the blade stage 13, and the inverted V-shaped blade 11 (1 la, Lib) is fixed to the placing portion 14. The inverted V-shaped insert 11 has a polycrystalline diamond layer (PCD layer) 16 on the front side of the super-hard alloy layer 15, and the PCD layer 16 is placed on the mounting portion 14 toward the surface side (the top surface side) on the rotational direction side. And it is fixed by soldering by silver solder or the like. The inverted V-shaped insert 11 is a first inverted V-shaped insert 11a having a guide angle 5 on the right inclined cutting edge (one inclined cutting edge) 17 7a which is a cutting edge, and is a cutting edge. The second inverted V-shaped blade lib having the lead angle 5 on the left inclined cutting edge (the other inclined cutting edge) 18a side is fixed to the blade table 13 of the rotary tool in the circumferential direction (Fig. 3). In the first inverted V-shaped insert 1 la (Fig. 2 (a)), the left inclined blade end edge which becomes the blade end edge of the center line Y which hangs from the tip end (upper end) of the blade edge (the other inclination) The inclination angle K2 of the blade end edge 1 7b is smaller than the inclination angle K1 of the right-inclined edge-cutting blade (one inclined cutting edge) 17a which is a cutting edge -9-201221322 blade. On the other hand, the second inverted V-shaped blade lib (Fig. 2(b)) is formed such that the center line Y and the first inverted V-shaped blade iia are formed in a front-rear direction. In other words, in the second inverted V-shaped insert 11b, the inclination of the right inclined blade end edge (one inclined blade end edge) 18b which is the blade end edge of the center line Y which is suspended from the tip end (upper end) of the blade edge is made. The angle K2 is smaller than the inclination angle K 1 of the left oblique cutting edge (the other inclined cutting edge) 18 8 which becomes the cutting edge, and specifically, the angle of the V groove is 45 degrees. In the first inverted V-shaped insert 11a, the inclination angle K1 of the right inclined cutting edge 17a which is a cutting edge is 22.5° with respect to the center line Y, and the inclination angle K2 of the left inclined blade end edge 17b is 22 to 14°. On the other hand, in the second inverted V-shaped blade lib, the inclination angle K1 of the left inclined cutting edge 18a which is a trimming edge is 22.5° with respect to the center line Y, and the inclination angle K2 of the right inclined blade end edge 18b is 22~14°. When the inclination angle K2 of the inclined blade end edges 17b and 18b is smaller than the inclination angle K1 of the inclined cutting edges 17a and 18a, the rigidity is lowered. On the other hand, if the difference is too small, burrs are likely to occur. The lead angles 5 in the first inverted V-shaped insert 11a and the second inverted V-shaped insert lib are each 10 to 20°. For example, in the case of another size, the diameter of the rotary tool 10 is 120 mm, the thickness T of the pedestal 12 is 2 mm, the number of blades is 6 to 30, the width T1 of the blade is 1.5 to 2 mm, and the rake angle α is 10 to 20 °, and the outer circumference is Escape angle 5~10°, the side escape angle 5~10°, the width of the apex cut (knife nose) Β, is 0.02~0.1mm.

S -10- 201221322 一例，當然可對應用途適宜地變更。 習知，在V溝加工或切成V形用的旋轉工具中的倒V 形刀片中，未考慮設置導角。這是因爲先端爲銳角，且V 溝加工或切成V形的深度只有1 · 5mm程度很淺，所以即 使設置導角其所産生的效果也小，另一方面，設置導角用 的加工也很麻煩等。 對於此，在本發明中，因爲在各倒V形刀片設置導角 ，並且將傾斜刀端刃的傾斜角度比成爲切邊刃的傾斜切邊 刃的傾斜角度小地形成，將各倒V形刀片交互地配置，所 以可減輕切削阻力，且可在一方的倒V .形刀片的切邊刃側 使基板不會發生毛邊地被尖銳地切削。在刀端刃側的切削 殘部，毛邊雖容易發生，但是接著藉由另一方的倒V形刀 片的切邊刃使切削殘部被尖銳地切削而使毛邊被除去，就 可進行無毛邊的V溝加工。 說明使用本發明的第1實施例的旋轉工具1〇對於鋁 基板施加V溝加工的情況。如第4圖所示，在上下配置旋 轉工具10、10，使上旋轉工具10右旋轉並且使下旋轉工 具10左旋轉，將鋁基板19朝箭頭方向運送，就可在鋁基 板19從上下形成剖面V形的溝（V溝）。 藉由第5圖說明此時的由旋轉工具1〇所進行的V溝 形成過程。從第5圖（a)的加工前的狀態，如同圖（b)所示 ，在下面側藉由右切邊刃（第1倒V形刀片1 la)形成v溝 ，另一方面，在上面側藉由左切邊刃（上下同樣爲正面視 右切邊刃（第1倒V形刀片1 la))形成V溝。 -11 - 201221322 接著，如同圖（c)所示，在下面側藉由左切邊刃（第2 倒V形刀片1 lb)使V溝的切削殘部20被切削加工，在上 面側藉由右切邊刃（上下同樣爲正面視左切邊刃（第2倒V 形刀片11b))使V溝的切削殘部20被切削加工。 在第5圖（b)右切邊刀17a側因爲是由銳角被尖銳地切 削，所以可不發生毛邊地漂亮地精整完成，左刀端刃17b 側因爲是鈍角，所以容易發生毛邊。但是，在同圖（c)中， 因爲藉由左切邊刃18a使切削殘部20被尖銳地切削，所 以毛邊被除去，可漂亮地精整完成。 如此，如同圖（d)所示，完成上下V溝的角度K各別 爲45度的V溝加工。因此，可由一步驟進行v溝加工， 作業效率更高。 第6圖的照片是顯示在鋁板上施加了銅電鍍的鋁基板 施加了 V溝加工的V溝剖面的照片，可了解在v溝的角 部未發生毛邊。 接著，由本發明的第2實施例的旋轉工具21，是與第 1實施例同樣，如第7圖、第8圖所示，具有倒V形刀片 22(22a、22b)的旋轉工具，在圓板狀的旋轉體（台座）丨2的 外周將鋸齒狀的刀刃台13在圓周方向等間距形成。此刀 刃台13是形成正面視倒V形狀，並且在該刀刃台13的旋 轉方向兩側形成被凹切成側面視L型的載置部1 4，將倒V 形刀片22(22 a、22b)固定在該載置部14。倒v形刀片22 ，是在超硬合金層15的正面側具有多結晶鑽石層（pcD層 )16’將PCD層16朝向旋轉方向兩側（刀頂面側）載置在載S -10- 201221322 An example can be appropriately changed depending on the application. Conventionally, in an inverted V-shaped insert in a V-groove or a rotary tool for cutting into a V shape, the provision of a lead angle is not considered. This is because the tip end is an acute angle, and the V groove is cut or V-shaped to a depth of only 1. 5 mm, so even if the lead angle is set, the effect is small. On the other hand, the processing for setting the lead angle is also Very troublesome. In this regard, in the present invention, since the guide angle is provided on each of the inverted V-shaped blades, and the inclination angle of the inclined blade end edge is formed smaller than the inclination angle of the inclined cutting edge which becomes the edge cutting edge, each inverted V shape is formed. Since the blades are alternately arranged, the cutting resistance can be reduced, and the substrate can be sharply cut without burrs on the side of the cutting edge of one of the inverted V-shaped blades. In the cutting residue on the blade edge side, the burrs are likely to occur, but then the cutting edge is sharply cut by the cutting edge of the other inverted V-shaped blade to remove the burrs, and the V-groove without burrs can be performed. machining. A case where the V-groove processing is applied to the aluminum substrate by using the rotary tool 1 of the first embodiment of the present invention will be described. As shown in Fig. 4, the rotary tools 10 and 10 are disposed above and below, the upper rotary tool 10 is rotated rightward, and the lower rotary tool 10 is rotated to the left to transport the aluminum substrate 19 in the direction of the arrow, so that the aluminum substrate 19 can be formed from the upper and lower sides. A V-shaped groove (V groove). The V-groove forming process by the rotary tool 1 此时 at this time will be described with reference to Fig. 5. From the state before the processing of Fig. 5(a), as shown in Fig. (b), the v groove is formed on the lower side by the right-cut edge (the first inverted V-shaped blade 1 la), and on the other hand, The V groove is formed by the left cutting edge (the upper and lower cutting edges (the first inverted V blade 1 la)). -11 - 201221322 Next, as shown in (c), the cutting residual portion 20 of the V groove is cut by the left cutting edge (the second inverted V-shaped blade 1 lb) on the lower side, and the right side is cut by the right side. The cutting edge (the upper and lower left cutting edge (second inverted V-blade 11b) is also formed in the upper and lower sides) so that the cutting residual portion 20 of the V groove is cut. In the fifth figure (b), the side of the right-cutting blade 17a is sharply cut by the acute angle, so that the edging can be beautifully finished without occurrence of burrs, and since the side of the left-edge blade 17b is an obtuse angle, burrs are likely to occur. However, in the same figure (c), since the cutting residue 20 is sharply cut by the left cutting edge 18a, the burrs are removed, and the finishing is beautifully completed. Thus, as shown in Fig. (d), the V-grooves of the angles K of the upper and lower V grooves are each 45 degrees. Therefore, the v groove processing can be performed in one step, and the work efficiency is higher. The photograph of Fig. 6 is a photograph showing a cross section of a V-groove in which a V-groove was applied to an aluminum substrate to which copper plating was applied, and it was found that no burrs occurred at the corners of the v-groove.

Similarly to the first embodiment, the inverted V-shaped insert 22 has a first inverted V shape at the guide angle 5 on the right inclined cutting edge (one inclined cutting edge) 2 3 a side which is a cutting edge. The blade 22a' and the second inverted V-shaped blade 22b' having the lead angle 5 on the side of the left inclined cutting edge (the other inclined cutting edge) 25a which is a cutting edge are alternately arranged in the circumferential direction and fixed to the rotary tool. The blade table 13 (Fig. 9). In the first inverted V-blade 22a (Fig. 8(a)), the left inclined blade end edge which becomes the blade end edge for the center line Y which hangs from the tip end (upper end) of the blade edge (the other inclined blade end) The inclination angle K2 of the blade 23b is formed smaller than the inclination angle K1 of the right oblique cutting edge (one inclined cutting edge) 23a which is a cutting edge. The height H1 of the right inclined cutting edge 23a and the left inclined blade end edge 23b is formed to be somewhat lower than the depth W1 (Fig. 11) of the V groove. Further, the lower end of the right inclined cutting edge 23a is formed with chamfered edges 24a, 24b which are continuous with the lower end of the left inclined blade end edge 23b and which increase the inclination angle K3 'K4 with respect to the center line Y. The chamfering blades 24a and 24b are chamfered (27) from a corner portion (H1) which is shallower than the depth W1 of the V groove. On the other hand, the second inverted V-shaped insert 22b (Fig. 8(b)) is formed such that the center line Y and the third inverted V-shaped insert 22a are bilaterally symmetrical. That is, 'in the second inverted V-blade 22b', the inclination angle of the right inclined blade end edge (the side inclined blade end edge) 25b which is the blade end edge of the center line Y which is suspended from the tip end (upper end) of the blade edge K2 is formed smaller than the inclination angle κ 1 of the left inclined cutting edge (the other inclined cutting edge) which becomes the cutting edge of 2 5 a. Further, the lower ends of the left oblique cutting edge 25a are formed with chamfered edges 26a and 26b which are continuous with the lower end of the right inclined blade end -13 - 201221322 blade 25b and which increase the inclination angles κ3 and Κ4 of the center line γ. The inclination angle K1 of the inclined cutting edges 23a and 25a which are the cutting edges, the inclination angle K 2 of the inclined blade end edges 2 3 b and 2 5 b which become the blade edges, the guide angle 6, the diameter of the rotary tool 21, and the pedestal The specific number of the thickness T of the 12, the number of cutting edges, the width T1 of the blade, the forward inclination angle 〇: the outer peripheral escape angle, the side escape angle, and the like are the same as in the first embodiment. Further, the inclination angles K3 and K4 of the chamfered blades 24a, 24b, 26a, and 26b are about 40 to 50 degrees, or about r〇.5 to R2.0. Further, these numbers are only an example, and of course, they can be appropriately changed depending on the application. A case where the V-groove processing is applied to the aluminum substrate by using the rotary tool 21 of the second embodiment of the present invention will be described. As in the first embodiment, as shown in Fig. 1, the rotary tools 21 and 21 are placed up and down, the upper rotary tool 21 is rotated rightward, and the lower rotary tool 21 is rotated to the left to transport the aluminum substrate 19 in the direction of the arrow. The aluminum substrate 19 is formed with a V-shaped groove (V groove) from above and below. The V-groove forming process by the rotary tool 21 at this time will be described with reference to Fig. 11. From the state before the processing of Fig. 1(a), as shown in Fig. (b), the V groove is formed on the lower side by the right-cut edge (the first inverted V-shaped blade 22a), and on the other hand, The V groove is formed on the side by the left cutting edge (the upper and lower sides are also the right side cutting edge (first inverted V blade 22a)). At the same time as the formation of the v groove, chamfers are formed at the corners of the V groove by the chamfered edges 24a, 24b. At this time, the substrate 19 is pressed inward by the chamfered blades 24a and 24b of the upper and lower inverted V-shaped blades 22a, respectively (the chamfering blade on the upper side is lower than the chamfering blade on the lower side is above).

Next, as shown in Fig. (C), the cutting residual portion 20 of the V groove is cut by the left cutting edge (the second inverted V-shaped blade 22b) on the lower side by the right cutting edge on the upper side (upper and lower sides) Similarly, the front left edge cutting edge (second inverted V blade 22b) cuts the cutting groove 20 of the V groove. At this time, since the substrate 19 is also a chamfered blade by the upper and lower second inverted V-shaped blades 2 2b (the lower side is the left chamfering edge 26a, and the upper side is the right chamfering edge (the upper and lower sides are also the front side left chamfering edge) 26a)) Each side acts inwardly, so the substrate 19 does not sway up and down. In the first aspect (b), since the right-cut side edge side 23a is sharply cut by the acute angle and the chamfering (24a) is formed, the finishing is completed without the occurrence of burrs, and the left-edge end edge 23b side is an obtuse angle. So it is prone to burrs. However, in the same figure (c), since the cutting residue 20 is sharply cut by the left cutting edge 25a and chamfered (26a) is formed, the burrs are removed, and the finishing can be beautifully finished. Thus, as shown in Fig. (d), the angle κ of the upper and lower v grooves is 45 degrees of V groove processing. Moreover, when the v groove is processed, the chamfering process is also completed. Therefore, the efficiency of work by one-step V groove processing and chamfering is very high. At this time, since the substrate 19 does not sway up and down, the residual thickness s of the substrate 19 after the V-groove processing is constant, and a high-quality processed product can be obtained. The photograph in Fig. 12 is a photograph showing a V-groove cross-section of a V-groove processed by an aluminum substrate on which an aluminum plate is applied on an aluminum plate, and no burrs are formed at the corners of the v-groove, so that it can be understood by chamfering The blade beautifully forms a chamfer -15- 201221322. Further, the photograph of Fig. 1 shows a state in which the cross-section of the substrate after the V-groove processing is displayed, and it is understood that the effect of the chamfered blade is such that the blade does not swing and the thickness S of the residual portion is constant, and the processed surface is also good. In the rotary tool 30 according to the third embodiment of the present invention, the basic configuration of the rotary tool 30 is the same as that of the first embodiment and the second embodiment. The rotary tool 30 is a first inverted V-shaped blade 32a having a guide angle 5 on the side of the product side inclined cutting edge (one inclined cutting edge) 3 1 a side, and a tilting edge edge on the end material side The second inverted V-shaped blade 3 2b having the lead angle 5 on the other side of the inclined cutting edge 33a is alternately arranged in the circumferential direction and fixed to the blade table 13 of the rotary tool. In the first inverted V-shaped blade 32a, the center line Y which is suspended from the tip end (upper end) of the blade edge is the end plate side inclined blade end edge (the other inclined blade end edge) 3 1 b of the blade end edge. The inclination angle K2 is formed smaller than the inclination angle K1 of the product side inclined trimming knife (the square inclined cutting edge) 3 la. The height H1 of the product side inclined cutting edge 31a is formed to be somewhat lower than the depth W 1 (Fig. 7) which is cut into a V shape. Further, a chamfering edge 3 4 a which is continuous with the lower end of the product side inclined cutting edge 3 1 a and which increases the inclination angle with respect to the center line Y is formed. The chamfering edge 3 4a is chamfered from a corner portion which is cut into a V-shape from a height H1 which is shallower than the depth W1 which is cut into a V shape. Further, a chamfered blade may not be provided on the lower end side of the end material side inclined blade end edge 3 1 b. Since the end material side is discarded, chamfering is not required. However, in order to maintain the strength of the blade, and in consideration of the processing work of the blade, etc., the blade end chamfer 35 of the inclined angle is provided at the lower end of the end-side inclined blade end blade 31b. Moreover, the height of the end piece side inclined blade end edge 3 1 b is cut to be -16-

On the other hand, in the second inverted V-blade 32b, the inclination angle K2 of the product side inclined blade end edge (one inclined blade end edge) 33b which is the blade end edge of the center line Y is inclined obliquely to the end material side. The inclination angle K 1 of the edge edge (the other inclined cutting edge) 3 3 a is formed small. Further, since the second inverted V-shaped blade 32b does not help the chamfer, it is not necessary to provide a chamfering edge. However, in order to maintain the strength of the blade, and in consideration of the processing work of the blade, etc., the lower end of the inclined edge end edge 3 3b of the product side and the lower end of the inclined edge edge edge 3 3a of the end material side are provided with a blade end chamfer 35 which increases the inclination angle. 35. Further, the height of the end material side inclined cutting edge 33a and the product side inclined blade end edge 3 3b is higher than the depth W1 which is cut into a V shape. Specifically, when the angle cut into a V shape is 35°, in the first inverted V-shaped blade 3 2a, the inclination angle K1 of the product side inclined cutting edge 3 1a which is the edge cutting edge is the center line. Y is 17.5°, and the inclination angle K2 of the end-side inclined blade end edge 31b is 17 to 14°. On the other hand, in the second inverted V-shaped blade 32b, the inclination angle K1 of the edge-side inclined cutting edge 33a which is the cutting edge is 17.5° with respect to the center line Y, and the inclination angle K2 of the product-side inclined blade end edge 33b. It is 17~14°. When the inclination angle K2 of the inclined blade end edges 31b, 33b is smaller than the inclination angle K1 of the inclined cutting edges 3 1 a, 3 3 a, the rigidity is lowered. On the other hand, if the difference is too small, it is easy to cause burrs. The lead angles 5 in the first inverted V-blade 32a and the second inverted V-shaped blade 32b are each 10 to 20°. For example, in the case of another size, the diameter of the rotary tool 30 is 120 mm, the thickness T of the pedestal 12 is 2 mm, and the number of blades is 6 to 30'. The width T1 of the blade is 1.5 to 2 mm, and the rake angle α is 10 to 20. -17- 201221322, the outer escape angle is 5~10°, and the side escape angle is 5~10°. Further, the inclination angle of the chamfered blade 34a is about 40 to 50 degrees, or about r〇.5 to R2.0. In addition, the above-described dimensions are an example, and it is a matter of course that the end surface of the printed circuit board can be cut by using the rotary tool 30 of the third embodiment. As shown in Fig. 16, the upper and lower rotating tools 30, 30' are arranged to be displaced away from the front and rear (left and right of Fig. 16), and the upper rotary tool 30' is rotated to the left and the lower rotary tool 30 is rotated to the right. The printed circuit board 36 is transported in the direction of the arrow, and the printed circuit board 36 is cut from the upper and lower sides into a V-shaped cross section. Here, the first inverted V-shaped blade and the second inverted V-shaped blade in the lower rotary tool 30 are formed symmetrically with respect to the front view of the upper rotary tool 30', so that it is called the third in the upper rotary tool 301. Inverted V-shaped blade and 2' inverted V-shaped blade. The V-shaped cutting formation process performed by such a rotary tool 30, 30' is explained by Fig. 17. In the state before the processing from Fig. 17(a), as shown in Fig. (b), the V-groove is formed on the lower side by the right-cut edge (the first inverted V-blade 32a). On the other hand, the V groove is formed on the upper side by the right-cut edge (the left-cut edge (the first 'inverted V-blade 32'a) which faces the tip end side upward). At the same time as the V groove is formed, the corner portion cut into a V shape is chamfered by the chamfering edges 34a, 344. Next, as shown in Fig. (c), the cutting residue 20 is cut on the lower side by the left cutting edge (the second inverted V-shaped blade 32b), and the left cutting edge is provided on the upper side (the tip end is made) The right-side cutting edge (the second 'inverted V-shaped blade 32'b)) faces upward to cut the cutting residue 20. Thus, as shown in (d), the angle at which the upper and lower sides are cut into a V shape is completed.

Further, the chamfering process (27) of the corner portion cut into the v shape at the same time as the V-shaped machining while the product side (Fig. 17 (b) to (d) is the right side) is also completed. Therefore, since the v-cutting and chamfering can be performed in one step, the work efficiency is very high. Further, in Fig. 17 (b) to (d), since the left side portion of the substrate 36 is an end portion which is to be discarded, it is not necessary to perform chamfering. For the V-shaped cutting insert and the chamfering insert (the two inserts are not provided with guide angles), the rotating tool is alternately arranged in the circumferential direction, and the number of cutting edges needs 30'. The same performance is used in this embodiment. The number of blades can be reduced to 12. Therefore, the number of high-priced diamond blades can be reduced, and the cost can be reduced.
