本発明は、石材等の剛性材の切断に用いられる切断砥石
に関する。詳細には、両側面に多数の突起が形成された
切断刃部を備えた突起付き切断砥石に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cutting wheel used for cutting rigid materials such as stone. Specifically, the present invention relates to a protrusion-equipped cutting grindstone having a cutting blade portion with a large number of protrusions formed on both sides.
（発明の背景）
従来、石材等の剛性材の切断加工技術において、リムタ
イプ、セグメントタイプ等の切断砥石が一般に用いられ
ている。(Background of the Invention) Conventionally, in cutting processing techniques for rigid materials such as stone, cutting wheels such as rim type and segment type have been generally used.
ところで、リムタイプは、金属製の基体の端縁に基体よ
りも肉厚な切断刃部が連続的に溶着されたものであり、
切断刃部が基体よりも肉厚であることから、切断加工技
術に基体が波切断材と接触することがなく、円滑に切断
加工し得るしのである。By the way, the rim type has a cutting blade that is thicker than the base and is continuously welded to the edge of the metal base.
Since the cutting blade portion is thicker than the base body, the base body does not come into contact with the wave cutting material during the cutting process, and the cutting process can be performed smoothly.
しかしながら、切断加工中、切粉の排出が円滑に行われ
ず、切断刃部に目詰まりを生じ、切れ味が低下し易く、
又切断刃部と被切断材との間に冷却水が供給され難いた
め、切断刃部及び被切断材が高温になり、夫々熱的影響
を受け、切断刃部は早く摩耗して寿命が短く、又被切断
材は切断面が変色したり脆（なり、良好な切断面に形成
され難い等の問題点がある。However, during the cutting process, chips are not discharged smoothly and the cutting blade becomes clogged, which tends to reduce sharpness.
In addition, since it is difficult to supply cooling water between the cutting blade and the material to be cut, the cutting blade and the material to be cut become hot, and each is affected by heat, causing the cutting blade to wear out quickly and shorten its lifespan. In addition, there are problems such as the cut surface of the material to be cut becomes discolored or brittle, making it difficult to form a good cut surface.
一方、セグメントタイプは、基体の端縁にセグメント状

ら、切断効率及び寿命が必ずしも実用」ユ充分なもので
はない。On the other hand, the segment type has a segment-shaped cutting blade welded to the edge of the base, and compared to the rim type cutting wheel, the gaps between the segments facilitate the discharge of chips and the supply of cooling water. Since the cutting blade part is not clogged, its sharpness is maintained for a long time, the cutting process can be performed with high cutting efficiency, and the service life is maintained for a long time due to less thermal influence. In addition, the material to be cut has a cut surface with less discoloration and less brittleness due to thermal effects. However, the cutting efficiency and lifespan are not necessarily sufficient for practical use.

A gap is formed in between, so that chips can be easily discharged and cooling water can be supplied easily.

される。(a) The heat dissipation area of the cutting blade part 3 is wide and the heat dissipation property is good, and during the cutting process, gaps are formed between both sides 4.5 of the cutting blade part 3 and the material to be cut, and cooling water is Since the material is smoothly supplied between the cutting blade part 3 and the material to be cut, the temperature rise of the cutting blade part 3 is suppressed, and deterioration of the cutting blade part 3 due to the temperature rise is prevented, so that it can be used for a long period of time. On the other hand, the material to be cut is cut into a good cut surface without being thermally affected by the temperature increase.

Furthermore, clogging of the cutting blade portion 3 and temperature rise can be further prevented, and thermal effects on the material to be cut can be suppressed to a low level.

等の恐れが少なく、長期間使用し得る。8 a, 8 b are at different positions from the symmetrical position,
For example, the protrusion 6a on one side 4 is the protrusion 6 on the other side 5.
The protrusions are arranged at positions corresponding to the gaps between the protrusions B and are formed so that the gaps C on both sides 4.5 do not coincide, so that during cutting, the impact force acting on each protrusion is applied to the cutting blade 3
The stress is not concentrated at the same time at symmetrical positions on both sides 4.5 of the cutting edge 3, and no stress concentration point occurs in the cutting blade portion 3. Therefore, there is little fear that the cutting blade portion 3 will break during the cutting process, and it can be used for a long period of time.

8a and 8b are hemispherical bodies whose tops are substantially flat, and are surrounded by curved lines;
Since there are no sharp corners and the impact force during cutting is dispersed, it is less likely to break and can be used for a long period of time.
（へ）切断刃部３の放熱面積が広く放熱性が良好である

Since a gap is formed between the blades, chips are discharged smoothly, the cutting blade does not become clogged, and its sharpness is maintained for a long time. In addition, cooling water is supplied smoothly, and the cutting blade has a wide heat dissipation area and has good heat dissipation, so the cutting blade and the material to be cut are prevented from rising in temperature and are not affected by thermal effects. is reduced, and deterioration is prevented. Furthermore, since the cutting blade has a large heat dissipation area and good heat dissipation, dry cutting can be performed without using cooling water.
