An intelligent production line for turning tool bit cavities and an application method are provided, which solve the problem that a production line in the prior art has low working efficiency. The intelligent production line has the beneficial effects of a compact arrangement structure, higher safety and improved working efficiency. The intelligent production line for turning tool bit cavities includes a robot. Material tables and at least one machining center are arranged around the robot. A transfer station used for transferring materials is arranged between the machining center and the robot. A protective fence is arranged between a position above the material tables and the robot, and between the transfer station and the robot. The robot is provided with a mechanical arm including a base plate. The base plate is provided with at least one clamping jaw and fixed with a laser detecting unit for detecting the materials.

A machine tool can prevent cutting fluid or the like, which has occurred within a cover, from leaking out through an opening when a door provided in the cover is open. The machine tool includes a door for opening and closing an opening provided in a cover for defining a work space, and a partition member which is attached, as a member separated from the door, to the cover and which shields a part of the opening to define a small opening smaller than the opening.

An object of the present invention is to provide a sealing member for machine tools which has excellent reliability because excellent sealability can be maintained for a long period of time and which can be manufactured efficiently at low cost. The sealing member for machine tools of the present invention includes a supporting member; a plate-shaped elastic member; and an adhesive layer which bonds the elastic member to the supporting member. The supporting member has a shape of a bent plate-like body, the elastic member is bonded to the supporting member via the adhesive layer laminated on a part of a front face of the elastic member so as to be curved along the bent shape of the supporting member, and a corner portion formed by a back face and one side face of the elastic member is assumed to be an edge portion in contact with an opposite material, and the one side face is formed by cutting.

A work-machine splash guard for enclosing a space for machining a workpiece, and preventing the spraying of chips and machining fluid, is equipped with: a front-surface door for opening and closing in the horizontal direction via an arc-shaped movement, and positioned on the front-surface side of the work machine; a side-surface door for opening and closing by performing an arc-shaped movement that is concentric with the front-surface door, and overlapping with the front-surface door; and door-locking switches for selectively allowing the opening/closing of the front-surface door and the side-surface door according to an opening/closing pattern.

A processing machine includes: an external cover that forms an appearance of the processing machine and defines and forms an internal space; and a safety belt connection portion that is disposed in the internal space and to which a safety belt is connectable. The external cover includes an openable lid. The safety belt connection portion is exposed to an outside of the internal space through an opening that is generated in the external cover when the lid is in an open state.

The application describes a machine tool adapted and arranged to carry out removal and addition of material on a work piece located in a work station, the machine having a first head arranged to remove material from the work piece and at least a second head arranged to process the work piece, each of the first and second heads being arranged to be moveable in at least two axes and preferably in 3, 4 or 5 axes and wherein the machine is arranged to control an environment of the work station. The work station is at least partially sealable. The machine has a clean side and a dirty side. Novel processing heads particularly adapted for use in the new machine tool are disclosed. These may also be retrofitted to CNC machines. The novel heads include heads adapted to carry out two processes simultaneously. Heads adapted to carry out heat and pressure treatment are also disclosed. Use of the processing heads to carry out analysis in manufacturing steps is disclosed as is the provision and use of heads that can carry out analysis as well as processing.

A processing machine comprises: a cover that is provided with an opening and defines a processing area; a first door that is slidable between a first position in which the opening is opened and a second position in which the opening is closed; a second door that is disposed to overlap with the first door inside the processing area and slidable between the first position and a third position that is opposite to the first position with respect to the second position and in which the second door cooperates with the first door to close the opening; and a rail member that includes a grooved portion and an abutment that engage with the first door and is provided at the second door to allow the second door to slide with respect to the first door. The grooved portion and the abutment are disposed outside the processing area.

A machine tool includes a bed that includes a guide unit, a first structure and a second structure that are each mounted over the bed, a first drive unit that moves the first structure along the guide unit, and a protector that covers at least part of the first drive unit. The protector is extendable and retractable with movement of the first structure, at least one of the first structure and the second structure includes a protector housing portion that houses at least part of the protector, and the protector housing portion is a space that is provided in a base portion of at least one of the first structure and the second structure and opened in a movement direction of the first structure. Accordingly, structures such as a headstock and a tool post can easily approach each other and the convenience of machining a workpiece by a machine tool can be increased.
