摘要： PROBLEM TO BE SOLVED: To propose a technical means compactly wiring a power cable of a built-in motor between a tool rest of a machine tool and a revolving type tool head mounted on the tool rest.SOLUTION: The power cable of a tool driving motor mounted on the revolving type tool head is relayed by a revolving connector and is reconnected to an electric cable of a type different from the power cable, and the electric cable is connected to a movable connector fixed to the tool rest mounted with the tool head and is further connected from the movable connector of the tool rest to a base supporting the tool rest through an electric cable whose bending radius is restricted by a Cableveyor (R). The revolving connector is supported by a protection member extending to a space of the tool rest formed on the side opposite to the tool head. The electric cable connecting the revolving connector and the movable connector fixed to the tool rest is a cable allowing twisting.

摘要： PROBLEM TO BE SOLVED: To prevent intrusion of cutting liquid into a motor by quickly detecting leakage of the cutting liquid with a compact and simple structure in regard to a technology for preventing intrusion of liquid, which is leaked from a rotary seal of a rotary joint provided between a non-rotating supply opening and a shaft end of a rotating shaft member, into a built-in motor for driving the shaft member, or the like.
SOLUTION: A seal member surrounding an opening of a liquid supply opening and the shaft end of the shaft member form a rotary seal. A first chamber is formed around the rotary seal, and the shaft member passes through a cylindrical hole of a fixed member, and the first chamber is communicated with a second chamber through a clearance 27 between the shaft member and the cylindrical hole. The clearance has an axial length and a clearance dimension which produce fluid resistance required to generate a pressure difference that can be detected by a pressure sensor provided in the first chamber when a normal quantity or more of fluid flows. The second chamber includes a drain opening.

摘要： PROBLEM TO BE SOLVED: To provide a machine tool which includes both functions of a lathe and a machining center, and allows cutting and machining of a wide plane with a large-sized rotary tool and heavy-duty cutting, and develops a machining program including tool change for two workpieces.
SOLUTION: A tool main spindle 51 is provided the traveling positions of which are controlled in 3-axis directions orthogonal to each other, and which is turnable around an axis (third direction, Y-axis) in the longitudinal direction to an operator, and rotates around an axis parallel to a face orthogonal to the axis in the third direction. The same structure as that of a conventional two-main spindle opposed lathe is provided as a workpiece retention part. At least one capstan rest 8 is disposed below the work axial line. Tool magazines 71R, 71L and tool changers 72R, 72L are arranged substantially above two workpiece main spindles 61R, 61L on both sides of the one tool main spindle 51.
