A processing apparatus includes a chuck table having a holding surface for holding a workpiece; a horizontal moving mechanism that moves the chuck table in a horizontal direction and is supplied with a first oil; and a vertical moving mechanism that moves a processing unit in a vertical direction and is supplied with a second oil. Before mounting the workpiece on the holding surface, the holding surface is imaged by a camera while being irradiated with light, and it is examined whether or not the picked-up image is emitting light. If there is a light-emitting part in the picked-up image, it is determined that oil is adhered to the light-emitting part.

The present invention provides a machine tool system including a machine tool body and a control device. The machine tool body includes: a cover that covers a machining region; chip expelling mechanisms that are disposed at a plurality of different positions inside the cover, that expel chips generated during processing, and a discharging ability of which is changeable; and a chip information obtaining unit that obtains information related to scattering directions of the chips during the processing. In accordance with the information related to the scattering directions of the chips and obtained by the chip information obtaining unit, the control device controls the discharging ability of one of the chip expelling mechanisms corresponding to a direction in which a largest amount of the chips have scattered so as to be larger than the discharging ability of another of the chip expelling mechanisms.

A processing machine line including multiple processing modules arranged in a width direction and loaded on a base where a machine body is movable in a front-rear direction; an automatic workpiece transfer machine to perform transferring of a workpiece by moving a conveyance robot in front of the base; an external cover to cover the processing module; a front cover to form a conveyance space of the conveyance robot, the front cover being provided with, for each processing module, an upper section cover that is open-and-closable in a lifting up manner, and a lower section cover configuring a cover front surface with the upper section cover; and a chip receiving box to be removable and attachable by being attached between the lower section cover and the base via an installation bracket that is attachable and removable with respect to a top section of the lower section cover.

A machining system comprises a machining device that machines a workpiece, a set-up station with which pallet workpiece attachment/detachment is carried out, and a pallet conveyance device that conveys the pallet between the machining device and the set-up station. A partially cylindrical operator door, which can rotate around a set-up table on which the pallet is mounted, includes a partially cylindrical outer door and a partially cylindrical inner door which rotate following coaxial circular trajectories of different radii. The set-up station is provided with an interlocking mechanism that causes the outer door and the inner door to rotate in an interlocked manner so that a shielded state is constantly maintained between the operator side and the pallet conveyance device side.

A machine tool system includes a machine tool having a processing chamber covered by a cover and a door for covering or uncovering an opening formed on the cover; a stocker for being removably mounted on the machine tool to thereby define a storage space outside the processing chamber; and a robot having a movement range spanning the storage space and the processing chamber when the stocker is mounted on the machine tool. In the machine tool mentioned above, the stocker includes a safety fence that defines, in cooperation with the outer surface of the machine tool, a protective space when the stocker is mounted on the machine tool. The protective space is a space for accommodating the storage space.

A mist extraction system is provided that includes a plenum box having an inlet configured to be coupled in fluid communication with a machine tool enclosure. A blower is coupled in fluid communication with the plenum box and is configured to draw air into the plenum box from the machine tool enclosure via the inlet of the plenum box and exhaust the air back into the machine tool enclosure via an outlet of the blower. A baffle plate is arranged in the plenum box to redirect the air drawn into the plenum box through the inlet of the plenum box and a filter panel is arranged in the plenum box to filter the air redirected by the baffle plate prior to the air entering the blower. A collector arranged to collect mist from the air condensed on the baffle plate and the filter panel.

Techniques are disclosed implementing a lighted guard system, which changes from one color (e.g. white) when the guard is down (i.e. closed) and/or a machine associated with the guard is operational, to another color (e.g. red) when the guard is up (i.e. open) and/or the machine associated with the guard is not operational. The triggering of the change in state of the guard may be facilitated by a switch that changes state based upon a position of the guard.

A blade mounting and dismounting jig is provided for mounting a blade on and dismounting a blade from a flange of a cutting apparatus which includes a boss, a blade mount for mounting the blade fitted thereover, the flange having an annular end face for supporting the blade thereon and being fixed to a distal end of a spindle, and a holder that cooperates with the flange in gripping and securing the blade in position. The blade mounting and dismounting jig includes a cylindrical jig body, a grip coupled to the jig body and having a diameter larger than the jig body, a plurality of first air ejection ports defined in a distal end portion of the jig body, a plurality of second air ejection ports defined in the jig body at a juncture between the jig body and the grip.

A disclosed system enables easy installation and removal of an in-machine robot for use in a machine tool and further enables easy replacement of a robot with another robot to suit an intended purpose. A machine tool system includes a machine tool with a cover that covers a machining space, and a robot unit on which an articulated robot is mounted. A portion of the cover of the machine tool has an opening to allow insertion of the articulated robot of the robot unit into the machining space through the opening. The articulated robot of the robot unit is inserted through the opening, and the opening is closed by a lid of the robot unit.

This machine tool is provided with: a partition that partitions a machining chamber and a tool storage chamber and that has an opening; a shutter; and a receiving member that is formed so as to receive cutting fluid. The partition includes a sidewall member that extends in the vertical direction and an inclined wall member inclined in such a manner so as to become lower from the sidewall member to the interior of the machining chamber. At least part of the opening is formed in the inclined wall member. The receiving member is positioned beneath the shutter, and in such a position so as to receive cutting fluid that drops down along the sidewall member when the shutter is opened.
