The machine tool may be a multi-axis machine tool and the stop block can be fixed to the machine tool or may be integrated therein.

A power/signal transmission structure includes: a movable body which has an electrical device, and at least a part of which moves in a processing chamber of a machine tool; a robot provided in the processing chamber; a first connector which relays at least one of power and signals, and which is provided in the movable body 48 and is electrically connected to the electrical device; and a second connector which relays at least one of power and signals, and which is provided in the robot, and is electrically connectable to and disconnectable from the first connector as the robot is driven, wherein at least one of power and signals is transmitted from outside to inside or from inside to outside of the electrical device through the first connector and the second connector.

A high frequency vibration spindle system which includes a spindle having a spindle housing and a spindle shaft disposed in the spindle housing; a toolholder, engaged with the spindle and adapted to be engaged with a tool; an electric power transmission device disposed at the front end or a rear end of the spindle, including a first coil and a second coil; the first coil is disposed on the spindle housing, and the second coil is disposed on the spindle shaft to be rotated with the spindle shaft coaxially; the first coil and the second coil are spaced with a gap; the second coil is adapted to receive an electric power from the first coil with a non-contact induction method; and a transducer, adapted to be controlled to vibrate the tool and disposed in the toolholder and electrically connected with the second coil to receive the electric power.

A measurement apparatus includes: a measuring probe; a power supply unit provided to the measuring probe; a first communication unit supplied power from the power supply unit and configured to perform communication of a type-1 signal via first communication means, the type-1 signal containing information regarding measurement performed in the measuring probe; and a second communication unit supplied power from the power supply unit and configured to perform communication of a type-2 signal via second communication means, the type-2 signal containing information regarding power supply performed in the power supply unit, the second communication means being more reliable than the first communication means. The measurement apparatus and a measurement system both having this configuration are capable of ensuring continuity of measurement performed with the measuring probe.

A machine tool that processes a workpiece with a tool includes a holding device that holds a workpiece or a tool used in processing the workpiece, a first connector attached to the holding device, a transmission line that transmits at least one of fluid, powder, electricity, and light, and including a second connector connectable to the first connector, a storage unit that stores and protects the transmission line, and a transmission line transport mechanism that transports a tip end of the transmission line and switches the transmission line between an expanded state and a recovered state. The transmission line is pulled out from the storage unit and connected to the holding device via the second connector in the expanded state, while being recovered by the storage unit in the recovered state.

A measuring system monitors a spindle. The measuring system includes a cylindrical housing which can be arranged in and mechanically firmly connected to a spindle housing.
