2. Description of the Related Art Conventionally, generally, a counter boring surface Z is formed on a building material K made of lightweight foam concrete as shown in FIG. 3A by cutting with an end mill. On the other hand, use of a diamond tip as a chain saw blade of a chainsaw has been proposed by Japanese Utility Model Publication No. 60-183119.

Since the spot boring by the end mill is performed from the vertical direction of the surface of the building material K, for example, as shown in FIG. 3B, the building materials K 1 and K 2 are arranged so as to overlap each other. It is impossible to improve work efficiency by forming Z 1 and Z 2 spot facing surfaces on both building materials at once. On the other hand, in order to realize such one-shot machining, it is conceivable to adopt a machining method that can cut from parallel direction like a chain saw, but with a conventional chain saw blade with a steel blade, the blade wear is severe and the above proposal It has not been realized, probably because it is not familiar with the configuration of the diamond tip.

Each cutting link 1 with a blade attached
Has the configuration shown in FIG. The side link 2 is a link to which no blade is attached. In FIG. 2A, reference numeral 4 denotes a blade supporting portion projecting from the link 1 and having a thickness T of 2.1 mm. A chip 5 having a width H of 3 mm is provided on the supporting portion 4 with a groove 6 on the supporting portion 4. It is fixed by brazing and so on. The tip 5 is a cemented carbide base 8 having a cutting edge 7 and a groove 6 made of sintered diamond or sintered CBN on the upper surface.
It is formed by combining and in one body.

FIG. 2B shows a state of a cutting edge in which the fixed tip 5 cuts and cuts into a work by rotating the chain in the direction of the arrow, and the scooping surface S has a positive scooping angle and a flank surface. N is formed in the direction in which the clearance angle projects.

With this structure, the tip 5 is completely fixed to the blade supporting portion 4 and does not fall off during the rotary cutting. Moreover, due to the positive scooping angle and the protruding clearance angle, the cutting edge of the cutting edge is broken. Since cracking does not easily occur and the protruding flank of the cemented carbide base 8 is worn faster than the cutting edge by cutting, there is no problem such as an increase in cutting resistance due to the protrusion.

As shown in FIGS. 1A and 1B, the chip 5
Is fixed only when the cutting links 1 constituting the endless chain arranged in a plurality of rows in the traveling direction of the chain (14 rows in the embodiment) have a required space both in the traveling direction and in the vertical direction. To form a blade. There are 130 fixed blades, and the trajectories of the blades in the 14 rows are formed so as to overlap one another. Therefore, when the endless chain is rotated, each blade sequentially hits the work piece and individually cuts, and the cutting of the array width progresses as a whole of the individual cuttings.

In addition to the construction of the cutting blade 7 made of sintered diamond or sintered CBN firmly fixed and the scooping surface and flank surface, the cutting edge of the cutting blade 7 is shown in FIG. 1A. As described above, since it is installed to the right or left side of the cutting surface of the work depending on the traveling direction of the chain, cutting resistance is reduced and the flow of chips is improved, so smooth and long-term cutting is possible.

As shown in FIG. 3B, the building materials K 1 and K 2 are arranged so as to overlap with each other by the chain saw 9 using the chain saw blade of the above-mentioned embodiment, and the counterbore surface Z 1 , Z 2
When it was cut, it was extremely smooth, and it was possible to perform spot facing work for 2 months or more without replacing the chain saw blade. For comparison, a steel chain saw blade was used, and the same work was performed. However, the cutting blade was worn out and the work became impossible in 2 or 3 days. Moreover, it was confirmed that the efficiency was extremely high as compared with the conventional end mill processing.
