Abstract

PURPOSE: To effectively use full length of the cutting edge of a cutting tool so as to prevent partial wear and heating and lengthen the life of a tool by rotationally driving a cutting device, and at the same time moving up and down a tool holder provided with a cutting tool on the lower part through a pressing device.
CONSTITUTION: An electromagnetic changeover valve 95 is actuated with a servo valve control part 113 by the position of piston 83 of a ram main body 27 and the command of a main control part 109, and oil feed circuits to the upper oil chamber 99 and the lower oil chamber 97 of the ram main body 27 are changed over. Hereby, the piston is moved up and down and the end mill 65 of a tool holder 63 is moved up and down. Meanwhile, a work W is clamed at one end with a work positioning device 9, and moved front and rear, right and left to move following to the desired cutting form. Namely, during cutting of the work W, the end mill 65 cuts the work W while moving up and down. Hereby, full length of the cutting edge of the end mill 65 is uniformly used, early partial wear is eliminated, the life of the tool is lengthened, chips are small to facilitate chip disposal, and heating is reduced.
