にナット４、フランジ３を順に取外した後、薄刃の切断
砥石１の取付け、取外しの作業をしていた。As shown in Fig. 2 (a), the cutting blade of the thin blade of the conventional cutting machine has a cutting edge portion in which abrasive grains are fixed to the annular metal plate 1a by electrodeposition or the like.
1b is made in one. Therefore, as shown in FIG. 2 (b), the nut 4 and the flange 3 were removed in this order, and then the work of attaching and removing the cutting blade 1 having a thin blade was performed.

薄刃の切断砥石11の取外し、取付けの作業をおこなうの
で、作業に時間がかかっていた。Especially with a cutting machine equipped with a grindstone shaft whose both ends are supported,
(See FIG. 1 (b)) Since both ends of the spindle 5 are supported by the spindle bearings 15, after releasing the support on one side,
Since the thin blade cutting grindstone 11 was detached and attached, it took a long time.

の再現性を確保する為に調整をする必要があった。Further, in a cutting machine equipped with a grindstone shaft whose both ends are supported, the support on one side of the spindle 5 is released every time when the thin-blade cutting grindstone 11 is detached and attached, so that the reproducibility of the support is ensured. I needed to make adjustments.
本発明の目的は、砥石軸の支持を解除することなく薄
刃の切断砥石の取外し、取付けのできる、両端を支持さ
れた砥石軸を備えた切断機を提供することである。An object of the present invention is to provide a cutting machine equipped with a grindstone shaft whose both ends are supported so that a cutting grindstone with a thin blade can be removed and attached without releasing the support of the grindstone shaft.
〔実施例〕 以下本発明を図面に基づいて詳述する。 [Examples] The present invention will be described in detail below with reference to the drawings.
第１図（ａ）、（ｂ）は本発明の一実施例を示すもの
である。1 (a) and 1 (b) show an embodiment of the present invention.

称に分割加工によってできる微小な隙間により２分割さ
れた、半円砥石11a、11bよりなる。FIG. 1 (a) shows a cutting blade 11 of a thin blade attached to a cutting machine of the present invention. The cutting stone 11 of a thin blade is divided into two parts by a minute gap symmetrically divided along the Y axis. It consists of semi-circular whetstones 11a and 11b.
分割加工によってできる微小な隙間により２分割され
ている半円砥石の各々には、砥石の装着精度を保証する
ための位置決め用穴11cが設けられている。Positioning holes 11c are provided in each of the semi-circular grindstones which are divided into two by a minute gap formed by the division processing so as to ensure the mounting accuracy of the grindstone.
薄刃の切断砥石を、２分割する方法は種々考えられる
が、例えば放電加工あるいはレーザー加工など一般的手
法である。しかし分割精度が良好で低歪みで分割できれ
ば前記の方法に限定されることはない。There are various methods for dividing the thin-blade cutting grindstone into two, but for example, a general method such as electric discharge machining or laser machining is used. However, the method is not limited to the above method as long as the division accuracy is good and the division can be performed with low distortion.

周振れの直接の原因となる。When the divided machining surfaces of the left-side semi-circular grindstone 11a and the right-side semi-circular grindstone 11b divided in this way are combined, the length is geometrically XX and YY due to the minute gap created by the division processing. Difference occurs. And this difference becomes a direct cause of the outer peripheral runout of the cutting blade of the thin blade.

る。Therefore, in order to prevent run-out on the outer circumference, the left half-circle grindstone
It is necessary to position and attach 11a and the right half-circle grindstone 11b. FIG. 1 (b) shows a holding structure for positioning and attaching the left semi-circular grindstone 11a and the right semi-circular grindstone 11b of the cutting machine according to the present invention. Both ends of the spindle 10 are supported by spindle bearings 15. Bushings 12 are located inside the supported ends of the spindle 10.
Is provided, and the screw for attaching the nut 14 is threaded. The grindstone 11 is sandwiched between a bush 12 and a flange 13, and is tightened with a nut 14 from the flange side.

る。Further, the bush 12 has a grindstone composed of semicircular grindstones 11a and 11b.
A plurality of positioning pins 12a for positioning and mounting 11 are provided. The positioning pin 12a is a semi-circular grindstone.
It corresponds to the positioning holes 11c provided in 11a and 11b.
第１図（ｂ）において薄刃の切断砥石11（半円砥石11
a、11b）の取り付けは以下に示す手順でおこなわれる。In FIG. 1 (b), a thin blade cutting wheel 11 (semi-circular wheel 11
Installation of a, 11b) is performed by the following procedure.
始めにナット14をゆるめフランジ13を移動させ（位置

の手順を逆におこなえばよい。First, loosen the nut 14 and move the flange 13 (the amount of protrusion of the positioning pin 12a + the thickness of the grindstone or more) to make space. Next, the positioning hole 11c of the thin-blade cutting grindstone 11 is inserted into the positioning pin 12a, the semicircular grindstones 11a and 11b are mounted, and then the nut 14 is tightened to press the flange 13. Removal of the thin blade cutting whetstone 11 (semi-circular whetstones 11a, 11b) may be performed by reversing the above procedure.
本発明に係る両端を支持された砥石軸を備えた切断機
によれば、両端の支持をを外す事なく薄刃の切断砥石を
交換することができる。更に、薄刃の切断砥石を外周振
れを少なく取り付けることができる。According to the cutting machine equipped with the grindstone shafts having both ends supported according to the present invention, it is possible to replace the thin-cutting grindstone without removing the support at both ends. Furthermore, a cutting blade with a thin blade can be attached with less runout on the outer circumference.
