<p>The utility model provides a cutting machine tool. Processing precision can be improved when a cam is used without need of particular increasing the rigidity of the cam. The cutting machine tool comprises a processing tool processing workpieces, a main shaft supporting the processing tool, a support body supporting the main shaft, and a base part supporting the support body by allowing the support body to swing freely, a main shaft driving mechanism, and a support body swinging mechanism. The main shaft driving mechanism allows the main shaft to reciprocate in the shaft direction of the main shaft and to rotate around the main shaft in the support body. The support body swinging mechanism is installed on the base part and allows the support body to swing from a reference position. The support body swinging mechanism comprises a slide block, a guiding part, a connecting part and a cam mechanism; the slide block is capable of reciprocating in a reference direction parallel to the main shaft in the reference position; the guiding part supports the slide block by allowing the slide block to reciprocate; one end of the connecting part can be connected with the slide block in a swinging manner, and the other end is connected with the support body in a swinging manner; and the cam mechanism allows the slide block to reciprocate.</p> |
