A numerically controlled machine tool can simultaneously perform a variety of machining operations using work on a first main shaft and work on a second main shaft. A first tool post is movable together with a second main shaft in the direction of a main shaft axis and in a direction orthogonal thereto in a plane, while a second tool post is movable at least in the same biaxial direction as the directions of movement of the first tool post. A control device superposes the movement required for the first tool post to machine work on the movement required for the second tool post to machine work, so that the machining operation of the work by the tool on the first tool post and the machining operation of the work by the tool on the second tool post are simultaneously performed.

Disclosed is a bar feeder, which comprises a swing member designed to be swingably moved by a rotation shaft located above a guide rail. In normal mode, the swing member is kept in a standby in the vicinity of an upper position where the swing member is located to extend across and over a guide rail up to a bar rack The swing member normally rotated to a lower position where the swing member is located on a far side from the bar rack with respect to the guide rail. During the process, the swing member receives a bar from the bar rack, and loads the bar to the guide rail. When a bar is removed from the guide rail, the movement of a bar to the swing member is inhibited by an inhibition member, and the swing member without a bar is moved to the lower position to create an ejection space between the rotation shaft and the bar rack The present invention makes it possible to readily remove the bar loaded in the guide rail therefrom.

A numerically controlled machine tool that is capable of simultaneously effecting a variety of machining operations using work on a first main shaft and work on a second main shaft, with a high machining efficiency. A first tool post 300 is movable together with a second main shaft 210 in the direction of a main shaft axis C2 and in a direction X1 orthogonal thereto in a plane, while a second tool post 400 is movable at least in the same biaxial direction as the directions of movement of the first tool post 300. A control device superposes the uniaxial or biaxial movement required for the first tool post 300 to machine work W1 on the uniaxial or biaxial movement required for the second tool post 400 to machine work W2, and issues an instruction for movement to the first tool post 300 or second tool post 400, so that the machining operation of the work W1 by the tool on the first tool post 300 and the machining operation of the work W2 by the tool on the second tool post 400 are simultaneously effected.

A turret (11) is clamped to a tool rest main body (10) by a pair of coupling members (27). During indexing rotation for selecting a tool, the tool rest main body (10) and the turret (11) are moved relatively in a Z-axis direction, and the pair of coupling members (27) are unclamped. At this time, the tool rest main body (10) is moved in the Z-axis direction relative to a lathe main body (100) in synchronism with the relative movement in the Z-axis direction between the tool rest main body (10) and the turret (11). This movement of the tool rest main body (10) is adjusted in direction and moving distance so that the relative movement between the turret (11) and a spindle table (1) is eliminated. As a result of this movement control, the turret (11) and the tool fitted to the former do not have relative displacement to the spindle table (1) and to a work, so that the danger of mutual interference among these constituent elements and the work can be eliminated.

A temperature-compensated crystal oscillator for correcting frequency variations caused by temperature changes by means of a differential amplifier which detects an unbalanced voltage in a bridge circuit including a temperature sensitive element for controlling a capacitance of a variable capacitor. The oscillator includes a circuit element having a temperature characteristic responsive to a temperature characteristic of the variable capacitor. The aforesaid circuit element is positioned in a current sink path of the differential amplifier.

The present invention provides a power-supply management device which can efficiently connect and disconnect power supply to an electric-powered section, and a machine tool including the power-supply management device. The power-supply management device (101) detects a synchronization command of a control program, and compares an operation time of the electric-powered section between synchronizations in each control system which is a synchronization target by the synchronization command on the basis of the detected synchronization command. Then, the power-supply management device (101) disconnects the power supply to the electric-powered section belonging to the control system except the control system having the maximum operation time of the electric-powered section between the synchronizations, and restarts the power supply at the end of the synchronization in each control system.
