Abstract

A horizontal machining center includes: a table driven in first and second directions (directions indicated by arrows 530p and 530q, respectively) allowing the table to approach and move away from a spindle, respectively; a magazine having a plurality of tool gripping claws; and a coupling mechanism for coupling the table and the magazine together and moving the magazine in one of the first and second directions when the table is driven in the other of the first and second directions. When a tool attached to the spindle is removed from the spindle, the table is driven in the first direction, and when a tool accommodated by the magazine is attached to the spindle, the table is driven in the second direction. A horizontal machining center having a simple structure and prevented from having a bulky structure can thus be accomplished.

Claims3

Dependent claims

A horizontal machining center comprising:

a spindle rotating a tool about a horizontal, predetermined axis and driven in a plane orthogonal to said predetermined axis;
a table, driven in first and second directions parallel to said predetermined axis to approach and move away from said spindle, respectively, for securing a workpiece;
a magazine having a plurality of grippers capable of gripping tools, and movable in a direction parallel to said predetermined axis for accommodating said tools;
and
a coupling mechanism for coupling said table and said magazine together and moving said magazine in one of said first and second directions when said table is driven in the other of said first and second directions, wherein:
when a tool attached to said spindle is removed from said spindle, said tool attached to said spindle is gripped by one of said grippers, and in that condition, said table is driven in said first direction;
and
when a tool accommodated by said magazine is attached to said spindle, said tool accommodated by said magazine, gripped by one of said grippers, is positioned on said predetermined axis, and in that condition, said table is driven in said second direction.
