The formation of 13 is facilitated. Further, since the inner peripheral portion of the sintered segment 16 is filled in the peripheral groove 13 and fixed to both sides of the outer peripheral end of the laminated saw body 10, the sintered segment 16 can be firmly joined to the laminated saw body 10. become.
Further, since the sintered ring 15 is divided by the laser beam to form the sintered segment 16, the circumferential length of the sintered segment 16 and the number of divisions can be arbitrarily set, depending on the application. A rotating saw can be easily obtained. Moreover, when the sintered ring 15 is divided by the laser beam, the split groove 17 is also formed by dividing the outer peripheral portion of the saw blade 10, so that the split groove 17 can be formed in a small number of steps. .

強固に接合することになる。 As is apparent from the above description, according to the present invention, the sintered segments are formed on both sides of the outer peripheral end of the laminated saw.
Since it sticks to the inner surface of the groove, the contact area is
Firmly join the sintered segment to the saw body.
You can In this case, the above-mentioned circumferential groove is located outside the two saw blades.
Form a recess in the peripheral edge that is recessed in the thickness direction, and
So that the parts face each other and are integrally fixed to each other
Therefore, the bonding force can be adjusted by changing the cross-sectional shape and the depth of the circumferential groove.
Easily shaped into a larger shape, such as a dovetail
Can be made. Also, the sintered pellets can be
Inside and around both sides of the outer edge of the saw by heating and compressing
After forming a sintered ring by adhering to the
And the outer periphery of the saw blades together with the laser beam.
The sintered segment and
Since the split groove is formed, the circumference of the sintered segment is
Direction length and number of divisions can be set arbitrarily,
To obtain a rotary saw according to the application easily and in a small number of steps
You can Also, after plating both sides of each saw,
If each saw blade is spot welded and a peripheral groove is
Form the boiled mushrooms and then sinter the pellets with a die
Inside and around both sides of the outer edge of the saw by heating and compressing
Since it is fixed to the
And press the sintered pellets into the combined saws
At this time, the plated copper melts at the bonding site and each member
It will be joined firmly.
