HIGH-SPEED MACHINING DEVICE

PROBLEM TO BE SOLVED: To provide a high-speed machining device to reduce a time needed for work machining and also reduce an impact of a machining tool against a work when performing work machining by a machining device which moves toward and from the work. SOLUTION: A main body 93 of a drilling device 7 is made movable by a cylinder toward a work, a drill 100 as a working fool is installed reciprocatedly on the main body 93 on the work side, and the main body 93 is moved at a high speed until a drill 100 energized elastically by a spring 105 is brought in contact with the work. When the drill 100 is moved backward from the main body 93 when the main body is brought in contact with the work, a switch 107 is operated so as to reduce the moving speed of the main body 93.
