Detailed description of the invention
Hereinafter, the mode for implementing the present invention is illustrated based on accompanying drawing.As shown in Figure 1 and Figure 2, the throw 10 of the 1st embodiment according to the present invention is the throw with inverted V-shaped sheet 11 (11a, 11b), along the circumferential direction equidistantly to form jagged sword platform 13 on the periphery of discoideus rotary body (base member) 12.This sword platform 13 is formed as front and sees the shape of falling V, and is the mounting portion 14 that L-type is seen in side at the side, direction of rotation face of this sword platform 13 formation incised notch, affixed inverted V-shaped sheet 11 (11a, 11b) in this mounting portion 14.Inverted V-shaped sheet 11 has polycrystalline diamond layer (PCD layer) 16 in the face side of hard alloy layer 15, is positioned in mounting portion 14 by PCD layer 16 towards side, direction of rotation face (rake side) and welds affixed by silver solder etc..
Inverted V-shaped sheet 11 along the circumferential direction alternately configures the 1st inverted V-shaped sheet 11a and the 2 inverted V-shaped sheet 11b and they is fixed on the sword platform 13 of throw, and the 1st inverted V-shaped sheet 11a is constituting sharp sword (profit I) right bank sword (one tilt sword) 17a side there is lead angle δ, the 2nd inverted V-shaped sheet 11b has lead angle δ (Fig. 3) in left bank sword (another tilts sword) the 18a side constituting sharp sword.
In the 1st inverted V-shaped sheet 11a (Fig. 2 (a)), dodge the left bank of sword and dodge sword (sword is dodged in another inclinations) 17b by constituting and formed less than the angle of inclination K1 of right bank sword (an inclination sword) 17a constituting sharp sword relative to the angle of inclination K2 of the centrage Y hung down from the front end (upper end) of blade tip.
On the other hand, the 2nd inverted V-shaped sheet 11b (Fig. 2 (b)) is formed as symmetrical relative to centrage Y and the 1 inverted V-shaped sheet 11a in terms of front.Namely, in the 2nd inverted V-shaped sheet 11b, dodge the right bank of sword and dodge sword (sword is dodged in an inclination) 18b by constituting and formed less than the angle of inclination K1 of left bank sword (another the tilts sword) 18a constituting sharp sword relative to the angle of inclination K2 of the centrage Y hung down from the front end (upper end) of blade tip.
Specifically, when the angle of V groove is 45 °, in the 1st inverted V-shaped sheet 11a, relative to centrage Y, the angle of inclination K1 constituting the right bank sword 17a of sharp sword being set to 22.5 °, the angle of inclination K2 that left bank is dodged sword 17b is set to 22～14 °.On the other hand, in the 2nd inverted V-shaped sheet 11b, relative to centrage Y, the angle of inclination K1 constituting the left bank sword 18a of sharp sword being set to 22.5 °, the angle of inclination K2 that right bank is dodged sword 18b is set to 22～14 °.If the angle of inclination K2 tilting to dodge sword 17b, 18b is too small compared with the angle of inclination K1 tilting sword 17a, 18a, then rigidity declines.On the other hand, if difference is too small, then burr is easily produced.
Lead angle δ in 1st inverted V-shaped sheet 11a and the 2nd inverted V-shaped sheet 11b is set to 10～20 °.If enumerating an example of other sizes, then the diameter of throw 10 is 120mm, the thickness T of base member 12 is 2mm, blade number is 6～30, the width T1 of sheet is 1.5～2mm, anterior angle α is 10～20 °, and it is 5～10 ° that periphery angle of relief (escapes げ angle), side angle of relief is 5～10 °, and the width B of nose-cut-ting edge is 0.02～0.1mm.It is of a size of an example it addition, above-mentioned, certainly suitably can change according to purposes.
In the past, in the inverted V-shaped sheet in the processing of V groove or the incisory throw of V, it may be said that do not consider to arrange helical pitch.Its reason is in that, owing to the depth as shallow that front end is acute angle, the processing of V groove or V cutting is to for about 1.5mm, even if so arranging helical pitch, the effect being generated by is also less, on the other hand, is used for arranging the processing trouble etc. of helical pitch.
Relative to this, in the present invention lead angle is set on each inverted V-shaped sheet, and the angle of inclination tilting to dodge sword is formed less than the angle of inclination tilting sword constituting sharp sword, and alternately configure each inverted V-shaped sheet, so while alleviating cutting resistance, substrate is cut in the sharp sword side of an inverted V-shaped sheet with will not producing burr tartly.Although easily producing burr in the cutting residual part dodge sword side, but by the sharp sword of another inverted V-shaped sheet ensuing, cutting residual part is cut tartly, and burr is removed, it is possible to realize the processing of carrot-free V groove.
The situation of aluminium base enforcement V groove processing is illustrated by the throw 10 using the 1st embodiment according to the present invention.As shown in Figure 4, configuration throw 10,10, makes throw 10 to right rotation up and down, and makes lower throw 10 to anticlockwise, and conveying aluminum substrate 19 in the direction of the arrow, from the groove (V groove) of upper and lower Formation cross-section V-arrangement on aluminium base 19.
By Fig. 5, now V groove forming process according to throw 10 is illustrated.From the state before the processing of Fig. 5 (a), as shown in Fig. 5 (b), V groove is formed by right-handedness sword (the 1st inverted V-shaped sheet 11a) in lower face side, on the other hand, V groove is formed in upper surface side by sinistration sword (making identical, front up and down be seen as right-handedness sword (the 1st inverted V-shaped sheet 11a)).
Next, as shown in Fig. 5 (c), cutting residual part 20 at lower face side V groove is cut processing by sinistration sword (the 2nd inverted V-shaped sheet 11b), and the cutting residual part 20 at upper surface side V groove is cut processing by right-handedness sword (making identical, front up and down be seen as sinistration sword (the 2nd inverted V-shaped sheet 11b)).

So as shown in Figure 11 (d), complete the angle K of the upper and lower V groove respectively V groove processing of 45 degree.Further, while carrying out V groove processing, chamfer machining is also completed.Thus, V groove processing and chamfer machining is carried out with an operation, working performance is high.Now, as described above, substrate 19 will not be moved in the vertical direction, so the residual thickness S of the substrate 19 after the processing of V groove is certain, it is possible to obtain the converted products of high-quality.
The photo of Figure 12 represents the photo implementing the V slot cross-section after copper-plated aluminium base enforcement V groove is processed on aluminium sheet, it is known that does not produce burr in V groove angle portion, has been carried out chamfering by chamfering blades gallantly.Additionally, the photo of Figure 13 represents the form in the substrate segmentation cross section after the processing of V groove, it is known that due to chamfering blades effect, it does not have produce the runout of blade, the thickness S of residual part is certain, and machined surface is also good.
Then, being applicable to the end face of cutting substrate according to the throw 30 of the 3rd embodiment of the present invention, its basic comprising and the 1st embodiment, the 2nd embodiment are identical.This throw 30 along the circumferential direction alternately configures the 1st inverted V-shaped sheet 32a and the 2 inverted V-shaped sheet 32b and they is fixed on the sword platform 13 of throw, 1st inverted V-shaped sheet 32a rolls oblique sword (one tilts sword) 31a side at product and has lead angle δ, and the 2nd inverted V-shaped sheet 32b rolls oblique sword (another tilts sword) 33a side at end material and has lead angle δ.
In the 1st inverted V-shaped sheet 32a, roll and tiltedly dodge sword (sword is dodged in another inclinations) 31b by constituting the end material dodging sword and formed less than product rolls the angle of inclination K1 of oblique sword (one inclination sword) 31a relative to the angle of inclination K2 of the centrage Y hung down from the front end (upper end) of blade tip.Product rolls the height H1 of oblique sword 31a and is formed more lower than the degree of depth W1 (Figure 17) of V cutting.Further, the lower end rolling oblique sword 31a with product forms chamfering blades 34a continuously, makes the chamfering blades 34a angle of inclination relative to centrage Y become big.Corner after V cutting processing, from the height (H1) more shallow than the V degree of depth W1 cut, is carried out chamfering by chamfering blades 34a.
Alternatively, it is also possible to do not roll, at end material, the lower end side tiltedly dodging sword 31b to arrange chamfering blades.Reason is in that owing to end material side is discarded, so being made without chamfering.But, for the intensity of retention tab, consider the processing operation etc. of sheet in addition, roll, at end material, the lower end tiltedly dodging sword 31b and the relief portion 35 making angle of inclination change big is set.It addition, the degree of depth W1 that end material rolls the aspect ratio V cutting tiltedly dodging sword 31b is high.
On the other hand, in the 2nd inverted V-shaped sheet 32b, by constitute dodge sword product roll tiltedly dodge sword (sword is dodged in an inclination) 33b relative to the angle of inclination K2 of above-mentioned centrage Y formed than end material roll oblique sword (another tilts sword) 33a angle of inclination K1 little.
It addition, the 2nd inverted V-shaped sheet 32b does not contribute to chamfering, so chamfering blades need not be set.But, for the intensity of retention tab, considering the processing operation etc. of sheet in addition, the lower end roll, at product, the lower end tiltedly dodging sword 33b, holding the material oblique sword 33a of inclination arranges the relief portion 35,35 making angle of inclination change big.It addition, end material rolls oblique sword 33a, product rolls the aspect ratio V tiltedly the dodging sword 33b degree of depth W1 height cut.
Specifically, when the angle of V cutting is 35 °, in the 1st inverted V-shaped sheet 32a, the angle of inclination K1 of the product oblique sword 31a of inclination constituting sharp sword is set to 17.5 ° relative to centrage Y, and end material rolls the angle of inclination K2 tiltedly dodging sword 31b and is set to 17～14 °.On the other hand, in the 2nd inverted V-shaped sheet 32b, the angle of inclination K1 of the end material oblique sword 33a of inclination constituting sharp sword is set to 17.5 ° relative to centrage Y, and product rolls the angle of inclination K2 tiltedly dodging sword 33b and is set to 17～14 °.If the angle of inclination K2 tilting to dodge sword 31b, 33b is too small compared with the angle of inclination K1 tilting sword 31a, 33a, then rigidity declines.On the other hand, if difference is too small, then burr is easily produced.
Lead angle δ in 1st inverted V-shaped sheet 32a and the 2nd inverted V-shaped sheet 32b is set to 10～20 °.If enumerating an example of other sizes, then the diameter of throw 30 is 120mm, and the thickness T of base member 12 is 2mm, blade number is 6～30, and the width T1 of sheet is 1.5～2mm, anterior angle α is 10～20 °, periphery angle of relief is 5～10 °, and side angle of relief is 5～10 °.Additionally, the angle of inclination of chamfering blades 34a is about 40～50 °, or it is about R0.5～R2.0.It is of a size of an example it addition, above-mentioned, certainly suitably can change according to purposes.
The situation using the throw 30 according to the 3rd embodiment that the end face of printed base plate is cut is illustrated.As shown in figure 16, upper and lower throw 30,30 ' is configured along front and back (in figure 16 for left and right) staggered positions, make throw 30 ' to anticlockwise, and make lower throw 30 to right rotation, conveying printed base plate 36 in the direction of the arrow, by printed base plate 36 from entering to be cut into cross section V-type up and down.Here, owing to the 1st inverted V-shaped sheet in throw 30 lower in terms of front and the 2nd inverted V-shaped sheet are symmetrically formed in upper throw 30 ', so in upper throw 30 ', being called the 1st ' inverted V-shaped sheet and the 2nd ' inverted V-shaped sheet.
By Figure 17, the V-type according to this throw 30,30 ' is cut forming process to illustrate.From the state before the processing of Figure 17 (a), as shown in Figure 17 (b), form V groove in lower face side by right-handedness sword (the 1st inverted V-shaped sheet 32a).On the other hand, V groove is formed in upper surface side by right-handedness sword (making blade tip front upwards for sinistration sword (the 1st ' inverted V-shaped sheet 32 ' a)).While forming V groove, by chamfering blades 34a, 34 ' a, V is cut corner and carry out chamfering.
Next, as shown in Figure 17 (c), cut residual part 20 in lower face side and be cut processing by sinistration sword (the 2nd inverted V-shaped sheet 32b), cut residual part 20 in upper surface side and be cut processing by sinistration sword (making blade tip front upwards for right-handedness sword (the 2nd ' inverted V-shaped sheet 32 ' b)).
So as shown in Figure 17 (d), complete the angle K respectively V-type cutting processing of 35 degree of upper and lower V cutting.Further, while carrying out V cutting processing, also complete product side (for right side in Figure 17 (b)～Figure 17 (d)) V cut the chamfer machining (27) in corner.Thus, carrying out V cutting processing and chamfer machining with an operation, working performance is high.
It addition, in Figure 17 (b)～Figure 17 (d), the left part of substrate 36 is the end material part of waste treatment, so not needing chamfer machining.
In the throw along the circumferential direction alternately configuring V cutting sheet and chamfering sheet (two panels is all without arranging helical pitch) in the past used, needing blade number is 30, but the blade number of the structure of same performance can be cut down to 12 by the present inventor in the present embodiment.Thus, it is possible to reduce the quantity of the diamond chip of high price, it is possible to realize the reduction of cost.
