Abstract
Disclosed herein is a gantry type hybrid parallel linkage five-axis machine tool composed of a machine framework a parallel spatial linkage mechanism, a feeding shaft mechanism, and a controller unit. The parallel spatial linkage mechanism is formed of three straight feeding molding dies rotatably hinged together with a base so that enabling this rotatable base to perform uni-dimensional linear motion and two-dimensional swiveling. Besides by controlling the operation of the feeding shaft mechanism with the controller unit, the parallel spatial linkage mechanism fixed to the machine framework is able to perform two-dimensional planar motion so as to operate the machine tools more accurately and efficiently in refining work.
