PROBLEM TO BE SOLVED: To provide a high quality product by having an X-axis cutting means furnished in parallel with an X-axis member on a device main body, a Y-axis cutting means arranged orthogonal against an X-axis circular saw and a Z-axis driving means to move in an Z-xis direction toward a work and machining it in less machining mandays. SOLUTION: A chain block is fixed on a Z-axis table, and the chain block is fixed on a chain. An X-axis cutting means 12 is mounted on the Z-axis table 7. X-axis curcular saws 25, 27, 29, 31 are installed on an X3 axis 23 of an X-axis drive transmission mechanism 17 in a state where specified intervals exist. A Y-axis cutting means is mounted on the Z-axis table 7. A Y-axis circular saw 45 is installed on a Y3 axis 43 of a Y-axis drive transmission mechanism 37. The Y-axis circular saw 45 is positioned at head end positions of the X-axis circular saws 25, 27, 29, 31. Consequently, it is possible to improve machining efficiency, to shorten machining time and to improve quality of a product.
