ABSTRACT:
A machine tool which has a swingable spindle head comprises a base member 1, a retaining member 5 attached swingably by a support shaft 3 to the base member 1, a spindle head 7 attached onto the retaining member 5, a lateral slider 15 being capable of linearly reciprocating in a linearly reciprocating direction along a chord of a circular arc described by an end portion of the retaining member 5, a longitudinal slider 21 provided in the lateral slider 15 reciprocating in a direction perpendicular to the chord, a connecting shaft 23 pivotally connecting the retaining member 5 to the longitudinal slider 21, and a linear drive system connecting to the lateral slider 15. When the linear drive system drives, the retaining member 5 can be swung around the support shaft 3, so that swing of the spindle head 7 can be permitted.
