A device which includes a guide member which includes a first end portion and an opposing second end portion. The first end portion defines a first plane and an opening is defined by the guide member, wherein the opening extends along the guide member in a direction perpendicular to the first plane. The device further includes a first bubble vial attached to the guide member wherein the first bubble vial extends within a second plane. The device further includes a second bubble vial attached to the guide member, wherein the second bubble vial extends within a third plane, the second and third planes are in angular relationship relative to one another and the first and second bubble vials are each rotationally adjustable relative to the guide member.

A machine tool system includes a machine tool including a processor to process a workpiece with a tool, and a bed on which the processor is mounted, a transport apparatus including two, left and right, legs spaced apart from the bed to transport the workpiece and feed the workpiece to the processor or discharge the workpiece from the processor, and a plate that connects the bed to the legs and is elastically deformable. The plate is upright such that a plate surface is aligned with a front-rear direction, and a connection portion of the plate that connects with the bed and a connection portion of the plate that connects with the legs are displaced in a front-back direction.

A turning tool includes a power receiving coil, a sensor, and a wireless unit. The power receiving coil receives power transmitted from a power transmitting coil in a non-contact manner. The sensor is electrically connected to the power receiving coil. The wireless unit transmits data detected by the sensor to an outside.
