要するという問題があった。Conventionally, jigsaws and circular saws have been used to cut these heat insulation panels, but since the surface plate of the heat insulation panel is usually a metal plate, the notch is not easy and especially the surface plate is made of stainless steel. If it is made of a hard metal such as a steel plate or a general steel plate, the cutting part bends instead of becoming a straight line, the dimensional accuracy is poor, and so-called burrs occur at the cutting part. I have to
Further, there is a problem that it takes a long time to cut when the thickness of the metal surface plate is increased.
