摘要： A machine tool with an automatic tool change function wherein a rotatable tool spindle carries a movable key engageable with either of a pair of key-ways formed on a tool. A tool changing arm, serving as a tool support device, friction-rotatably supports at least one tool for being selectively inserted within and removed from the tool spindle. When tool changing operation is to be performed, rotation of the spindle is changed to a predetermined speed permitting key-engagement. A first confirming device is provided for confirming the fact that the spindle has reached a first predetermined position during rotation thereof. The tool change arm is then operated to remove the tool from the spindle in response to the first confirming device. A second confirming device is provided for confirming that the spindle has reached a second predetermined position during rotation thereof. Prior to insertion of the tool into the spindle, the movable key is withdrawn, and in response to the second confirming device the movable key is moved outwardly into engagement with the predetermined key-way of the first and second key-ways.

摘要： In a machine tool with an automatic tool change function, a rotatable tool spindle carries a movable key engageable with a key-way formed on a tool. A tool changing arm, serving as a tool support device, friction-rotatably supports at least one tool for selectively inserting and removing same into and from the tool spindle. When a tool change operation is to be performed, rotation of the spindle is changed into a predetermined speed permitting key-engagement. A detecting device is provided for detecting movement of the movable key to confirm engagement of the movable key with the key-way of the tool. A clamp device clamps the tool inserted into the spindle in response to the detecting device. After the tool is clamped on the spindle, rotation of the spindle is changed into a machining speed. A confirming device is provided for confirming that the spindle is reached at a predetermined angular position during rotation thereof. The tool change arm is operated to remove the tool from the spindle in response to the confirming device.

摘要： A tool storage magazine of the type wherein a plurality of tool sockets each for removably storing a cutting tool therein are pivotably carried on an indexable element is provided with an engaging member moved by a hydraulic cylinder for pivoting each tool socket at a tool taking out position from a horizontal position to a vertical position through engagement with a pair of engaging rollers which are rotatably supported by each tool socket and located outside the side faces of each tool socket. The magazine is further provided with a locking mechanism which prevents a holding plunger of any tool socket indexed to the tool taking out position from being disengaged from a tool received in the tool socket until the tool socket is pivoted to its vertical position.

摘要： In a grinding machine, a grinding wheel is digitally fed toward a workpiece being supported by a rest apparatus. Means is provided to measure a diametral dimension of the workpiece during a grinding operation. A taper amount of the workpiece ground under the support of the rest apparatus being positioned at its advanced position is calculated at the time when the measuring means generates a signal for finishing a grinding operation on the workpiece. An advanced position of the rest apparatus is compensated for a next grinding operation in response to the calculated taper amount.

摘要： A numerical controller for a machining center comprising a microprocessor, which selectively executes an automatic programming function and a numerical control function. The microprocessor selectively displays on a CRT display unit various information which instructs an operator to input machining information regarding the blank and finished shapes of a workpiece and the mounting position of the workpiece on a work table. The operator inputs the machining information with a key board-type data input device in response to the information displayed on the CRT screen, and the machining information is stored in a data storage device. Based upon the stored machining information, the microprocessor then displays on the CRT screen the blank shape and the finished shape of the workpiece so that the operator can observe if the machining information has been correctly input. Unless modification of the stored machining information is required, the microprocessor prepares the numerical control (NC) program based upon the stored machining information. The microprocessor, in response to a machining start command, executes the numerical control function and controls the operation of the machining center in accordance with the NC program.

摘要： A guard device for a grinding wheel in a grinding machine comprises a side guard plate pivotably mounted upon a guard body for covering one side face of the grinding wheel. A front cover member is slidably mounted upon the top portion of the guard body for covering the upper front portion of the grinding wheel. A latch member is mounted on the front cover member to be engaged with a saw-toothed member so as to restrict movement of the front cover member away from the periphery of the grinding wheel but to allow movement of the front cover member toward the periphery of the grinding wheel. A locking member is pivotably mounted on the top of the guard body to lock the side guard plate in a closed state. When the locking member is pivoted to be disengaged from the side guard plate, the saw-toothed member is also disengaged from the latch member.

摘要： A numerical controller for a machining center comprising a microprocessor connected to a data input device, a CRT display device and a data storage device. The microprocessor prepares an NC program for a workpiece to be machined, based upon machining information manually input by the use of the data input device and stored in the data storage device. The debugging of the prepared NC program is then executed, wherein the microprocessor obtains by calculation a workpiece interference space defined outwardly from the outer periphery of the workpiece, based upon workpiece blank shape and dimension data and workpiece mounting position data stored in the data storage device. The microprocessor further calculates, based upon the NC program, a tool path along which a tool spindle of the machining center would be moved relative to a work table in accordance with the NC program. The microprocessor ascertains based upon the tool path, a tool interference space, defined outwardly from the outer periphery of each tool, and the workpiece interference space, whether or not the tool interference space would enter the workpiece interference space in any rapid feed movement if relative movement between the tool spindle and the work table were effected in accordance with the NC program. When detecting the entry of the tool interference space into the workpiece interference space, the microprocessor displays on the CRT screen a message informing an operator of the occurrence of an interference.
