美しい切削肌を得ることが可能となる。2. Description of the Related Art In general, as shown in FIG. 8, when a workpiece W is machined by a circular saw, a cutting mark (cutter mark) on a cutting edge side becomes dense and looks beautiful. As it approaches the center of the axis, it becomes coarser, and irregularities become noticeable in the cutting trace. Therefore, it is desirable to use a circular saw having a small diameter and a small tooth width in order to obtain a beautiful cutting surface, but in this case, the maximum cutting thickness by the circular saw becomes small. In view of such a problem, conventionally, as shown in FIG. 6, as shown in FIG.
2) are arranged on the upper and lower sides, respectively, with the circular saw 4 attached to the main shafts 43 and 44.
There is provided a sawmill (circular sawing machine) in which the sawing lines (center lines in the plate thickness direction), which are processing lines 5, 46, are aligned and mounted on the same line. According to this, the yield is good,
It is possible to obtain beautiful cut skin.

４５，４６の寿命に差がでるなどの問題があった。In FIG. 6, a is the thickness of the workpiece W that can be machined by the circular saws 45 and 46, and b is the machining by the circular saw 46 on the lower side which is the preceding cutting side. This is the maximum thickness that can be achieved, and c is the thickness (c = ab) processed by the circular saw 45 on the upper side. However, in the conventional circular saw machine, since the relative positions of the upper and lower circular saws 45 and 46 with respect to the material feeding surface 41 are fixed, when a> b, the lower circular saw 46 always has the maximum thickness. Must be processed. As shown in FIG. 7A, a workpiece W having a material thickness a = b / 2 is processed, and a workpiece W having a material thickness a = b is processed as shown in FIG. When comparing the feeding speeds when cutting, the material thickness a =
It has been obtained that the feeding speed of the workpiece W of b must be about 30% slower than the feeding speed of the workpiece W having the material thickness a = b / 2. Further, since the loads on the upper and lower circular saws 45 and 46 are different depending on the thickness of the workpiece W, there is a problem that the life of the circular saws 45 and 46 is different.
