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 tool transport system includes a display unit, a plurality of machine tools, a tool storage unit, a transport device for transporting a designated tool among tools stored in the tool storage unit to a designated machine tool among the plurality of machine tools and a controller for controlling the tool transport system. The controller executes a process of acquiring stocked tool information defining identification information of each tool stocked by the tool transport system, a process of specifying a plurality of tools to be used in the plurality of machine tools on the basis of a machining schedule of workpiece in the plurality of machine tools, a process of specifying an unstocked tool that is not defined in the stocked tool information among the plurality of tools to be used, and a process of displaying identification information of the unstocked tool on the display unit.

A numerical controller performs control for changing a tool mounted on a spindle to another tool stored in a tool magazine based on a machining program. The numerical controller analyzes a command by a block of the machining program, predicts a time required for machining by the analyzed command, and selects a tool changeable before a tool change command, during tool selection, based on the predicted time.

A machine tool includes a motor configured to rotate a spindle, a tool magazine holding a plurality of tools, and a controller. The controller has a storage unit storing motor information indicating that the motor is a synchronous motor. When the machine tool stops, while a tool exchange process is carried out, due to electric power outage, operation of a stop button, a value of a drive current of the motor, or a value output from the sensor, the controller uses a command for the synchronous motor, based on the motor information, as a part of a series of commands for recovery of the machine tool, where the tool exchange process is a process in which a tool attached to the spindle is changed with one of the plurality of tools of the tool magazine.

An automatic tool exchange system which allows a tool management mode to be arbitrarily selectable between a fixed address scheme and a memory random scheme in operation of the same machining center. The control unit for controlling the respective drive units of the tool exchanger and the magazine includes a storage unit for storing tool information containing a registered correspondence relationship between the tools and corresponding addresses of the stowage parts of the magazine, a modifying unit for modifying the tool information, and a tool exchange instruction unit for sequentially designating the tool to be used in each of the machining steps in accordance with the machining program, and driving the magazine to move the stowage part at the address corresponding to the designated tool to a predetermined position based on the tool information so that the tool is located at the exchange position at a predetermined timing. The control unit is configured to manage the tool in a mode selectively switchable between a first tool management mode in a fixed address scheme for returning the tool after use to a corresponding address, and a second tool management mode in a memory random scheme so as to stow the tool after use at an unoccupied address where the tool for next use has been previously stowed, and allow the modifying unit to modify the correspondence relationship between the tool after use and the address, which has been contained in the tool information.

A machine tool having a tool magazine for changing a tool attached to a spindle is equipped with an initial operation speed setting unit configured to set the operation speed of the tool magazine to an initial operation speed, an operation speed adjusting unit configured to be operated by the user to thereby adjust the operation speed of the tool magazine relative to the initial operation speed, an actuator configured to actuate the tool magazine, an operation speed acquisition unit configured to acquire the operation speed of the tool magazine after adjustment of the operation speed made by the operation speed adjusting unit, and an actuator control unit configured to control the actuator to actuate the tool magazine at the operation speed acquired by the operation speed acquisition unit.

A machine tool includes: an imaging unit for capturing an image of a tool from a side of the tool; a shape extraction unit for extracting the shape of the tool from the image of the tool captured by the imaging unit; a wear detection unit for detecting the degree of wear of the tool based on the shape of the tool; and a changing unit for changing at least one of the pitch and the depth of cut according to the degree of wear.

A container treatment system (1, 13) that has at least two working areas (AP). Each of the working areas (AP) respectively comprises at least one exchangeable working tool (2) and/or one adaptable format part. Furthermore, the container treatment system (1, 13) comprises at least one automatic exchange machine (10) which is movable, in particular drivable, to the at least two working areas (AP), which automatic exchange machine (10) can be connected selectively to any of the respective working areas (AP), in particular using centering means (22, 32), and which automatic exchange machine (10) comprises tools for exchanging the working tools (2) and/or for adapting the format parts of the respective working area (AP). The invention further relates to an automatic exchange machine (10) for exchanging working tools (2) and/or for adapting the format parts of at least two different working areas (AP) of a container treatment system (1, 13).

A method of priming a minimum quantity lubrication (MQL) tool includes determining a category of the tool, supplying a short-prime MQL dosage if the tool is a first category or if both a second category and lubricated within a first predetermined timeframe, and supplying a long-prime MQL dosage if the tool is the second category and has not been lubricated within the predetermined timeframe. The category is based on internal passage complexity of the tool.

Provided is a method and device for computer-assisted optimization of the occupancy of magazine spaces by tools within at least one tool magazine for a machine tool, one or more workpieces of a workpiece type being manufactured with the aid of the tools provided by a magazine unit at a provisioning place. A step of the claimed steps of the method described in the description is the optimization of the occupancy of the magazine spaces by tools so that the total waiting time is minimized, wherein the total waiting time is composed of individual waiting times which result in each case from the difference between the detected provisioning period and the detected working step duration if the value of the difference is positive, otherwise the individual waiting time assumes the value zero.
