（産業上の利用分野）
本発明は鋸刃に係り、さらに詳細には、例えば帯鋸、丸
鋸あるいはハクソーのごとき鋸刃に関するものである。DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Industrial Application Field) The present invention relates to a saw blade, and more particularly to a saw blade such as a band saw, a circular saw, or a hacksaw.
（従来の技術）
従来、例えば金属性の大きなワークピースを切断（切削
）する装置として帯鋸盤が使用されている。(Prior Art) Conventionally, a band saw has been used as a device for cutting, for example, a large metal workpiece.
帯鋸盤に使用される帯鋸刃においては、切粉のスムーズ
な排出と、直進性維持のため鋸刃にあさり出しが行なわ
れ、このあさり出し作業は、あさりを付けない歯、すな
わち直歯に対してあさり打ち出し最を数値で規定しであ
る。Band saw blades used in band saw machines are set up to ensure smooth discharge of chips and maintain straightness. This set up work is performed on teeth that are not set up, that is, straight teeth. The maximum launch distance of the ball is specified numerically.
例えば第５図に示すごとく、鋸刃１０１の各歯（右あさ

Ｓ）の切れ歯で作る幅方向の線分ａ１〜ａ５は、所定の
数値で均等にあさり出しされている。For example, as shown in FIG.
The line segments a1 to a5 in the width direction formed by the cutting teeth of S) are evenly cut out by predetermined numerical values.
なぜならば、−歯に大きな切削抵抗をかけないよう切削
作用を分散させ、安定した高速重切削が行なわれるよう
構成されている。This is because - the cutting action is dispersed so that large cutting resistance is not applied to the teeth, and the structure is such that stable, high-speed, heavy-duty cutting can be performed.
（発明が解決しようとする課題）
上述のごとく、各歯が交差してなす幅方向の線分ａ１〜

A5 can be set, but the saw blade wears out with use and its shape becomes longer! ! l] cannot be maintained.
ずなわら、第６図に示すごとく、直歯１０７Ｓの摩耗ｆ

５Ｌの摩耗ＩＢも摩耗が進行する。However, as shown in Fig. 6, the wear f of the straight tooth 107S
Left and right bruises f@1 O3R1105m for il△
When comparing the wear ff18 of the straight tooth 107S, the wear ff of the straight tooth 107S is
As 1A wears, the left and right set teeth 103R, 10
The wear progresses in the wear IB of 5L as well.
摩耗が進行しＡが完全に摩耗してしまうと、直ｔｆＪ１
０７ｓの線分ａ２およびａ４は左右のあさり歯１０３Ｒ
１１０５Ｌの線分ａ１およびａ５に吸収されるかたちと

Ｌの切削抵抗の分散が均一でなくなる。When the wear progresses and A is completely worn out, the direct tfJ1
Line segments a2 and a4 of 07s are left and right set teeth 103R
It is absorbed by the line segments a1 and a5 of 1105L, and the straight tooth 107S and left and right set teeth 103R, 105
The cutting resistance of L will not be uniformly distributed.
このため、左右のあさり歯１０３Ｒ１１０５Ｌの方が直
歯１０７Ｓより抵抗が上廻り、更に第５図に示す分散切
削を可能とする直歯１０７８の有効高さｂがなくなるた
め切粉幅の分断が不可能となる。For this reason, the resistance of the left and right set teeth 103R1105L is higher than that of the straight tooth 107S, and furthermore, the effective height b of the straight tooth 1078 that enables distributed cutting shown in Fig. 5 is eliminated, so the chip width cannot be divided. It becomes possible.
このことは、鋸刃切断が溝切り切断であることを考える
と、有効ガレット面積を一定とするならば、直歯１０７
Ｓ、左右のあさり歯１０３Ｒ，１０５Ｌによる切粉の分
断作用がなくなり、鋸帯厚そのものの切粉幅となる。Considering that the saw blade cutting is a groove cutting, this means that if the effective gullet area is constant, the straight tooth 107
S, the cutting action of the chips by the left and right set teeth 103R, 105L is eliminated, and the width of the chips becomes the same as the thickness of the saw band itself.
このため、切削切粉の体積が増し高速重切削時において
は、安定したり粉の排出が困難となるという問題がある
。For this reason, there is a problem in that the volume of cutting chips increases and it becomes difficult to stabilize and discharge the powder during high-speed heavy cutting.
そこでこの発明は、上述した課題に鑑み創案されたもの
であって、鋸刃の摩耗が進行してもより長時間切削抵抗
の分散、スムーズな切粉の排出を維持し、安定した高速
重切削が行なえるあさり形状を備えた鋸刃の提供を目的
とする。Therefore, this invention was devised in view of the above-mentioned problems, and even if the wear of the saw blade progresses, it maintains the dispersion of cutting force and smooth discharge of chips for a longer period of time, and enables stable high-speed heavy cutting. The purpose of the present invention is to provide a saw blade with a scavenging shape that allows for cutting.

を行なっておく。At this time, the set-up launch ω of set-up machining must have an inclination angle θ1 of both lines of the tooth of 151! As described above, after the effective height H of the straight teeth that enables distributed cutting has been processed to 0.05 ml or more, processing is performed to a value that allows a regular punch a to be obtained.
なお、各歯（右あさり歯３Ｒ１左あさりｆＩ５Ｌ、直歯
７８）が交差してなず幅方向の線分Ｌ１〜Ｌ５は、所定
の数値で均等に配分加工されていることは勿論である。It goes without saying that the line segments L1 to L5 in the width direction where the teeth (right set tooth 3R1, left set tooth 3R1, left set fI5L, straight tooth 78) intersect and are evenly distributed with predetermined numerical values.
また、第３図に示す符号１３は、掬い面を表わす。Further, the reference numeral 13 shown in FIG. 3 represents a scooping surface.
