Abstract:
1. A machine tool comprising: a bed including a base portion, and two side walls provided standing along respective sides of the base portion and opposing each other across an interval; a first saddle formed of a rectangular frame member having vertical sides paralleling a perpendicular first axis and transverse sides paralleling a horizontal second axis, both horizontal end portions of said first saddle being supported on rear faces of the side walls of the bed so as to be movable along the first axis; a second saddle having an upper portion and a lower portion each supported by the first saddle and provided to be movable along the second axis; a spindle head disposed within the first saddle and supported by the second saddle to be movable along a third axis perpendicular to the first axis and the second axis; a spindle for retaining a tool at the front thereof, the spindle axis paralleling the third axis and the spindle being supported by the spindle head to be rotatable about the spindle axis; a table for carrying workpieces, the table disposed on the bed; a first guide mechanism for guiding the travel of the first saddle along the first axis; a second guide mechanism for guiding the travel of the second saddle along the second axis; a third guide mechanism for guiding the travel of the spindle head along the third axis; a first feed mechanism for moving the first saddle along the first axis; a second feed mechanism for moving the second saddle along the second axis; a third feed mechanism for moving the spindle head along the third axis; and a rotary drive mechanism for rotating the spindle about the spindle axis.
