PROBLEM TO BE SOLVED: To simply and effectively obtain a plate mold with a desired shape by a method wherein a tool having a drilling part and a cutting part is arranged in a tool fixing part so as to form a vertical shaft. ;SOLUTION: When a plate material 9 is properly arranged, a drill motor 33 is driven so as to rotate a sawblade-housing tube 13 and simultaneously a sawblade cylinder is lowered so as to drill the surface of the plate material, when the drilling is completed, by means of a stop signal given to the drill motor 33, the rotary speed of a sawblade 21 past through the plate material 9 gradually becomes lower and simultaneously the sawblade 21 works to its lowest point by pressurizing the sawblade cylinder 17, resulting in chucking the sawblade to a chucking part 43. In this case, since a rotary motor 79 rotates synchronously with the drill motor 33, the chucking position of the sawblade 21 always coincides with the chucking part 43, resulting in precisely chucking with the sawblade 21. Accordingly, the damage and break of the sawblade 21 are prevented from developing.;COPYRIGHT: (C)1999,JPO
