機構。[Claims for Utility Model Registration] A tool rest in which three blades are arranged in a direction Y perpendicular to the cutting direction In the mechanism for selecting a cutter, the fluid pressure drive mechanism has two piston/cylinder mechanisms having a small diameter D1 and a large diameter D2 in parallel, and the small diameter piston/cylinder mechanism has a small diameter piston in a small diameter cylinder with a stroke of 2H. The small-diameter cylinder is divided into a first chamber and a second chamber, and the small-diameter piston and the turret are connected by a small-diameter rod having a diameter of d1 that passes through the second chamber, and the large-diameter piston cylinder The mechanism has a large-diameter piston arranged in a large-diameter cylinder with a stroke H, and is divided into a third chamber and a fourth chamber on the sides corresponding to the above-mentioned first chamber and second chamber, and is connected to a tool rest. The large-diameter rod is passed through the fourth chamber, and when the small-diameter piston is at the stroke H position, the tip of the large-diameter rod is brought into contact with the large-diameter piston at the end position on the fourth chamber side. , The diameter of the piston and rod is D22>D12-d
A blade selection/positioning mechanism for a movable spindle lathe characterized by the following relationship:
