<p>A working machine such as a machine tool, a spinning machine, a press machine, etc., for executing cutting, plastic machining, etc. The machining efficiency and machining accuracy are improved by inclining a driving portion or shaft members such as a bearing shaft and a main spindle for supporting and driving machining means such as tools so that the machining means can be arbitrarily oriented and inclined at an angle easily. This working machine supports tiltably one of the side of a shaft member for supporting the machining means or the driving portion for the machining means in an axial direction with a point of its axis as the center, supports movably the other side of the shaft member or the driving portion in an arbitrary direction in which the axis is inclined and is made eccentric and inclines the machining means by thus inclining the shaft member or the driving portion by its movement adjustment. The one of the sides is supported rotatably by using a spherical bearing while the other side is supported movably by using a double eccentric cam mechanism, two pairs of wedges opposing each other, a piezoelectric device, an electrostrictive device, a hydraulic or pneumatic cylinder, or the like, so that inclination by its movement adjustment can be effected easily and smoothly.</p> |
