Zusammenfassung: | Disclosed is a machine tool capable of simplilfying its structure and machining at a high degree of fixation and at high speed by minimizing vibration and thermal displacement of the machine tool. The machine tool includes: a base having a mounting space on which a workpiece is mounted, shaft holes formed on facing wall surfaces, and a pair of first shaft sliding parts formed to face each other at both sides of the mounting space; a pair of saddles combined with the first shaft sliding parts of the base to slide to a first shaft and having a pair of second shaft sliding parts formed to face each other at both sides in a direction intersecting the first shaft; a cross piece combined with the second shaft sliding parts to slide to a second shaft and having a pair of third shaft sliding parts formed to face each other at both sides in a direction perpendicular to a flat surface formed by the first shaft and the second shaft; a vertical ram combined with the third shaft sliding parts of the cross piece and sliding in a direction perpendicular to the flat surface formed by the first and second shafts, wherein a tool for machining a workpiece is mounted at an end portion of the vertical ram; and a table arranged in the mounting space of the base and mounted on the base to relatively rotate with respect to the base through the shaft holes of the base.
내부에는 가공물이 장착되는 장착공간이 구비되고, 마주하는 벽면에 축홀이 형성되며, 장착 공간의 양측으로 마주하도록 한 쌍의 제1축슬라이딩부가 형성된 베이스; 베이스의 제1축슬라이딩부와 결합되어 제1축으로 슬라이딩되며 제1축과 교차되는 방향의 제2축슬라이딩부가 양측으로 마주하도록 한 쌍으로 형성된 새들; 새들의 제2축슬라이딩부와 결합되어 제2축으로 슬라이딩되며 제1축 및 제2축이 이루는 평면에 수직한 방향의 제3축슬라이딩부가 양측으로 마주하도록 한 쌍으로 형성된 크로스피스; 크로스피스의 제3축슬라이딩부와 결합되어 제1축 및 제2축이 이루는 평면에 수직한 방향으로 슬라이딩되며 단부에 가공물을 가공하기 위한 공구가 장착되는 수직램; 및 베이스의 장착공간에 배치되며, 베이스의 축홀을 통해 베이스와 상대회전 가능하도록 베이스에 설치된 테이블;을 포함하는 공작기계가 소개된다. |
