The present invention relates to a steel plate cutter, and more particularly, to a cutter that can cut the steel plate with the correct dimensions by supporting the steel sheet to be cut so as not to fall.

In general, a steel sheet cutter may be used for various purposes as a machine for cutting steel, but the cutter of the present invention is used for a test piece production. The steel sheet to be cut in the present invention is used as a basic material for electromagnetic products. Among these steel sheets, oriented electrical steel sheets become materials for transformers and high-efficiency motors, and non-oriented electrical steel sheets become materials for motor rotating machines. Material grade determination of such steel sheet is determined by magnetism. Among them, iron loss and magnetic flux density are the key to determination. At this time, the test piece is cut and manufactured to determine the material grade, and the cutting length and the cutting width of the test piece directly affect the iron loss and the magnetic flux density. Therefore, the work of cutting the steel sheet with the correct dimensions of the cutter is very important for the accurate production of the test piece.
