The cleaning device includes a base, an indexed table, a driving mechanism and a power transmission mechanism. The driving mechanism includes a driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear.

A needle screw fitted to a compressed fluid supply part that is provided on a nozzle main body of a dust removing device adjusts the jet flow rate of a first compressed fluid from a jet nozzle by adjusting the flow path area of a first fluid supply path. Meanwhile, the suction flow rate of a second compressed fluid to be discharged into a discharge flow path is adjusted by adjusting the flow path area of a second fluid supply path by turning a nozzle main body-side adjustment screw that is provided on the nozzle main body and a suction nozzle-side adjustment screw that is provided on a suction nozzle.

A driving device including a drive shaft and a first engaging member. The drive shaft rotates around a first axis. The first engaging member is disposed on the first axis to rotate integrally with the drive shaft. The power transmission mechanism includes a second engaging member, a propeller shaft, a piston, and a reduction gear. The second engaging member is disposed on the first axis engageable with/disengageable from the first engaging member. The propeller shaft is rotatable integrally with the second engaging member around the first axis. The piston reciprocates the second engaging member between a first position and a second position along a direction of the first axis. The reduction gear is joined to the other end side of the propeller shaft to decelerate the rotation of the propeller shaft. The reduction gear causes an output shaft joined to an object to rotate around a second axis.

An air-blowing method includes the steps of blowing, inside a machine tool, air onto a workpiece after machining, issuing a workpiece pick-up advance notice signal for notifying beforehand of pick-up of the workpiece by a robot or a worker, on the basis of a task state of the robot or an operation of the worker, and calculating the additional time for air blow on the basis of a time required by the robot or the worker to arrive at a workpiece pick-up position in front of the machine tool after the workpiece pick-up advance notice signal is issued, where air blow is extended by just the additional time in the step of blowing air.

In a post-processing method for a workpiece, a workpiece machined by a machining device is conveyed by a robot, from the machining device to a post-processing device, information regarding a state, at the machining device, of the workpiece after machining is acquired, a processing time for post-processing of the workpiece by the post-processing device is determined by a control device on the basis of the information regarding the state of the workpiece after machining, and the post-processing is performed on the workpiece by the post-processing device for just the processing time that is determined.

A chip conveyor includes: a cover body; a guide plate configured to guide chips, which are conveyed inside the cover body, so as to be directed from a chip receiving position toward a chip discharging position; a case attached to the cover body and having an internal space provided therein; and a float switch configured to detect, based on a coolant flowing from inside the cover body into the internal space, that a liquid level of the coolant inside the cover body is equal to or greater than a prescribed liquid level. The cover body includes a first space and a second space that are partitioned from each other by the guide plate. The cover body is provided with: a first opening allowing communication between the first space and the internal space; and a second opening allowing communication between the second space and the internal space.

A machining system includes: a working machine that machines an article while supplying a dielectric working fluid to the article; a robot that transports the machined article from the working machine; a controller that controls the robot; and a recessed wall part that is provided outside the working machine so as to demarcate the transport path of the article. The robot includes a gripping part that grips the article and a rotating part that rotates the gripping part. The controller is configured to move the gripping part with the machined article along the transport path while rotating the gripping part in the recessed wall part by means of the rotating part.

A tool for machining surfaces, edge regions, and contours comprising at least one disk-shaped base body rotatable around a tool axis and a plurality of flexible machining means, which are arranged on a circumference of the base body, wherein the machining means are formed rod-shaped and are arranged spaced apart from one another and extend substantially radially outward from the circumference of the base body, wherein at least two disks, between which the machining means are arranged, are arranged in the direction of the tool axis.

A machine tool is equipped with a second supply pipe having elasticity and having one end side fixed to a spindle head and the other end side fixed to an arm portion, a cover provided within a machining area, and rollers. When the spindle head is moved in a direction to come close to the arm portion, the second supply pipe is bent and then a portion of the second supply pipe is brought into abutment against the cover. The rollers are provided at a portion of the cover against which the second supply pipe is brought into abutment, and are configured to reduce friction between the cover and the second supply pipe when the second supply pipe moves relative to the cover in an abutment state against the cover.

A cutting tool holding mechanism for detachably holding a cutting tool includes: a collet chuck configured to clamp and unclamp the cutting tool; a piston disposed deeper on the proximal side of the spindle than the collet chuck and configured to urge the collet chuck by the pressure of a fluid supplied from the proximal side of the spindle in the direction from the proximal side toward the distal end side of the spindle so that the collet chuck unclamps the cutting tool; a spool valve provided in the piston and configured to open thanks to centrifugal force at the time when the spindle is turned, so as to supply the fluid fed from the spindle side to the cutting tool.
