摘要： A weight measurement system and a weight measurement method using a robot, by which a weight greater than a weight capacity of the robot can be measured. The system has a robot, a robot controller for controlling the motion of the robot, and an arithmetic processing unit for calculating the weight of an article to be measured. The robot is configured to apply a force to a working point connected to a tank so that at least one of support points or a part of a support surface of the tank is lifted, and simultaneously, the remaining support point or the remaining part of the support surface of the tank is grounded. The weight of the tank containing processing fluid can be measured based on a relationship between the force applied to the working point by the robot and a lever ratio.

摘要： A tool gripping mechanism includes a tool holder and a shaft to which the tool holder is attached. The shaft is fixed to a rotary shaft of a spindle device. A plurality of magnets are disposed in pairs on concentric circles on surfaces of the tool holder and the shaft which face each other. When the tool holder is in a specific phase with respect to the shaft, the magnets of the tool holder and the magnets of the shaft attract each other, and the tool holder is aligned with respect to the shaft in that phase.

摘要： A linear drive unit and a machine tool having the linear drive unit, capable of being applied to various applications, while taking into consideration the balance between the thrust force and the cogging of a linear motor. The linear drive unit has a magnetic gap changing mechanism which is configured to change a magnitude of a magnetic gap between a coil and a magnet, by displacing at least one of the coil and the magnet so that the coil and the magnet approach or are separated from each other.

摘要： A tool holder holding a rotating tool can be sucked in a direction of a rotational axis of a spindle and a direction perpendicular to the direction of the rotational axis, using a chuck. A projection is provided on an outer peripheral surface of the tool holder, and caused to collide against another projection with the spindle kept rotating, to displace the tool holder. Thus, runout and dynamic balance of the rotating tool are adjusted.

摘要： A precision machining/measurement device and a robot that conveys a workpiece to the device are covered by a cover, and a space covered by the cover is partitioned by a partition cover into a space where the precision machining/measurement device is installed and a space where the robot is installed. When a temperature inside the space where the robot is installed falls within a predetermined temperature range, a door provided in the partition cover is opened, and the robot supplies the workpiece to the precision machining/measurement device through the opened door.
