Endless cutters such as band saws and belt saws are widely used for grooving and cutting glass, precious metals, etc.This type of endless cutter is shown in Figure 7.
A hollow band base 1 is formed by connecting the end faces of flat steel plates, and abrasive grains having a U-shaped cross section as shown in FIG. It consists of a blade 2.

During this rotation, the workpiece 6 is pressed against the tip surface 2a of the abrasive cutting edge 2, thereby achieving cutting and grooving of the workpiece 6.

よく加工することが困難になるという問題があった。As described above, the conventional endless cutter has an abrasive cutting edge 2 formed at the edge of a band base 1 made of a flat thin plate. In this way, when the flat thin plate band base 1 is used, when the endless cutter is run around between the pulleys, the stress distribution applied to the band base 1 is large at the center and small at the edges. Therefore, the tension state of the edge part, that is, the tension state of the abrasive grain cutting edge 2, cannot be obtained sufficiently, and the abrasive grain cutting edge 2 causes "runout", etc., and the workpiece 6 is machined with precision. The problem was that it was difficult to do so.
本発明は上記従来の問題点を解決するためになされたも

ーを提供することにある。The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to provide an endless cutter that ensures a sufficient tension state of the abrasive cutting edge and enables high-precision precision machining. It is in.
本発明は上記目的を達成するため次のように構成されて

されている。In order to achieve the above object, the present invention is configured as follows. That is, the present invention has a hollow band-shaped band base and an abrasive cutting edge provided around the edge of the band base, and an endless belt that is wound between pulleys and travels around between the pulleys. The Kanku is characterized in that the band base is provided with at least one of a groove or a hole that tensions the abrasive cutting edge during circular travel between the pulleys.

加工が達成されるのである。In the present invention having the above configuration, by providing grooves or holes, for example, along the longitudinal direction of the band base, in the cross section of the band base, a very small cross-sectional portion where the grooves or holes are provided and the other The maximum cross section is formed,
Of these, the largest cross-sectional area, which has a large cross-sectional area, receives most of the driving force from the pulley. Therefore, by providing a groove or a hole inside the edge, the cross-sectional area of the edge becomes much larger than the area where the groove is formed, and this edge accounts for a large portion of the driving force received from the pulley. It will bear the power of As a result, the edge is subjected to concentrated tension and becomes tense, so the abrasive cutting edge formed at the edge inevitably becomes tense, thereby preventing the abrasive cutting edge from wobbling. As a result, highly accurate precision machining of the workpiece can be achieved.
以下、本発明の実施例を図面に基づいて説明する。なお

In each embodiment of the present invention, the same components as those in the conventional example are denoted by the same reference numerals, and redundant explanation thereof will be omitted.

張り力により加工をする上での適切な緊張状態を保つ。1 and 2 show the structure of a first embodiment of the present invention. The difference between the embodiment of the wood brush 1 and the conventional example is as follows.
A desired number of grooves 7 are provided in the longitudinal direction of the band base 1 by appropriate means such as cutting or etching. This groove 7 is provided inside the abrasive cutting edge 2. Therefore, as shown in FIG. 2, when the cross section of the endless cafter 3 is taken, the abrasive cutting edge 2 is formed in a section of the band base 1 that has a large cross-sectional area. As is well known, when tension is applied to a member whose cross-sectional area varies drastically, the part with the larger cross-sectional area will bear most of the tension. Therefore, similarly in the case of the endless cutter 3 in the embodiment of the wood brush 1, the forming part of the abrasive cutting edge 2, which has an extremely larger cross-sectional area than the groove part, receives most of the pulley driving force. The abrasive cutting edge 2 maintains an appropriate tension state during processing due to its tensile force.
この緊張状態においては、砥粒切れ刃２が「振れ」等を
起こすことはないから、被加工物６に対する精度のよい
精密加工を達成することが可能となるのである。In this tensioned state, the abrasive cutting edge 2 does not "run out" or the like, so it is possible to perform precise machining on the workpiece 6 with high precision.

に対する横滑りを防止することができる。In the embodiment of the wood brush 1, the grooves 7 are provided not only on the front side of the band base 1 but also on the back side.
If a fitting protrusion corresponding to this groove 7 is provided around the surface of J 4.5, the band base 1 and the pulley 4.5 will be in a fitted state, and the band base 1 (endless cutter 3) will not slide sideways with respect to the pulley. can be prevented.

状態を保つこととなり、これにより、前記第１の実施例
と同様に、被加工物６に対する精！加工が可能となる。FIG. 3 shows the configuration of a second embodiment of the present invention. A characteristic feature of the embodiment of the wood brush 2 is that a plurality of pins 8 are arranged in the longitudinal direction (cutter traveling direction) in the central width portion of the band base 1. In this way, when tension is applied to the band base 1 with 68 arranged around the center,
Most of the tension is carried by the edge of the band base 1 without the holes 8. Therefore, even in the case of the second embodiment, since most of the pulley driving force is carried by both end edges of the band base 1, a relatively large tensile force acts on the abrasive cutting edge 2. The abrasive cutting edge 2 maintains sufficient tension for machining, and as a result, as in the first embodiment, the precision of the workpiece 6 is reduced. Processing becomes possible.
なお、本実２の実施例の場合も、六８に嵌合する凸部を
プーリ５．６に周設すれば、穴８と凸部との嵌合により
、エンドレスカッター３のプーリ５．６も対する横滑り
および走向方向の滑りを共に防止することができる。In the case of the second embodiment as well, if a convex portion that fits into the sixth 8 is provided around the pulley 5.6, the engagement between the hole 8 and the convex portion will cause the pulley 5.6 of the endless cutter 3 to Both side-slip and strike-direction slip can be prevented.

被加工物６の精密加工が達成できる。Another embodiment of the invention is shown in FIGS. 4 and 5. The embodiment shown in FIG. 4 has grooves 7 diagonally provided in the band base 1, and the embodiment shown in FIG.
is installed in the horizontal direction. By providing the grooves 7 obliquely or horizontally in this manner, the so-called stiffness of the band base 1 is increased. As a result, it is possible to prevent the abrasive cutting edge 2 from wobbling when the endless cutter 3 runs around, and as a result, it is possible to obtain the same effect as when the abrasive cutting edge 2 is directly tensioned. . In other words, by providing the grooves 7 as shown in FIGS. 4 and 5, it becomes possible to indirectly (as a result) tension the abrasive cutting edge 2,
Precision machining of the workpiece 6 can be achieved.

きる。Furthermore, if the grooves 7 are formed as shown in FIGS. 4 and 5, the cooling water supplied during processing of the workpiece 6 can easily reach the grinding part (cutting edge) through the cutting surface 7, and the grinding process The cooling effect of the area can be sufficiently increased. Also, in the embodiment shown in FIG. 5, if a protrusion corresponding to the groove 7 is provided around the pulley 4.5, the fitting between the groove 7 and the protrusion allows
It is possible to prevent the endless cutter 3 from slipping in the longitudinal direction.

Furthermore, although the grooves are provided at the same position on the front and back sides, the present invention is not limited to this, and the grooves 7 may be provided on one side of the front and back, or on both sides of the front and back. Even when provided, the positions of the grooves on both sides may be shifted from each other. Further, the number of grooves 7 can be arbitrarily set according to the width, thickness, material, etc. of the band base 1 so that the abrasive cutting edge 2 can obtain an optimal tension state. Further, the shape of the groove 7 is not limited to the rectangular groove of this embodiment, but may take any desired shape such as a 7-shaped groove or a U-shaped groove.

Further, in this embodiment, each hole 8 has the same size and shape, but the holes may be individually arranged in different sizes. Further, in the second embodiment, the holes 8 are provided one by one at equal intervals, but the holes may not be spaced evenly, and a plurality of holes 8 may be connected to form a long shape.
