段減速式割出刃物台。 NC where the turret is rotated and indexed by fluid pressure drive
In an indexing tool post for a machine tool, a neutral position is provided in a fluid pressure motor that drives the turret indexing shaft and a hydraulic circuit that drives the fluid pressure motor, and that switches the rotational direction of the fluid pressure motor and communicates with the supply/discharge circuit. and a speed adjustment circuit provided on the discharge circuit side of the three-position solenoid switching valve to adjust the rotational speed of the fluid pressure motor in two stages, high and low, when switching the rotation speed of the turret. Based on the command from the NC device, the three-position electromagnetic switching valve is placed in the neutral position for a short period of time, stopping the supply of pressure oil to the fluid pressure motor, and at the same time connecting the fluid pressure motor's supply/discharge circuit to reduce the inertia of the turret rotating section due to the viscosity of the oil. A two-stage reduction type indexing turret that absorbs
