PURPOSE: To reduce the total length of a cutting machining table by making the superposing part on a bed of a slide table a machining slide area while making the projecting part from the bed of the slide table a non-machining slide area.

CONSTITUTION: Each slide table 14 is divided into a superposing part 141 nearly half the table on a machining position A side which is the center side of its bed and a projecting part 152 which is projected out from the side end part in the longitudinal direction X of the bed 11. The superposing part 141 is a part which is fixed and handled after being superposed on top of the bed 11 while the projecting part 142 forms an article housing space E which is positioned right under the projecting part 142 and on the outside of the side and face of the bed 11. The mechanical feed part 161 of a feed driving device 16 is installed being faced downward on the end of each projecting part 142 and a motor 162 is installed on its lower end and on the article housing space E side. Each of the superposing parts 141 and the projecting parts 142 of the slide tables 14 are determined to agree with each of the machining slide areas and non-machining slide areas of tables 15 which support cutting edges 20 respectively. Since a part of the feed driving device 16 can be housed in the article housing space E, the total length of the cutting machining table TM can be reduced.
