A tool magazine receives a plurality of tools which are provided for arrangement on a tool spindle of a machine tool, and a method for changing tools using a tool magazine. The tool magazine exhibits a guide rail arranged in a fixed position on a machine base, a magazine carriage displaceably mounted on the guide rail, a rotary drive arranged on the magazine carriage and having a magazine shaft which can be rotated around a shaft axis of rotation, at least two magazine wheels arranged non-rotatably on the magazine shaft and having a plurality of tool holders, and a transfer device linearly displaceable along a transfer axis transverse to the guide rail and which picks up a tool arranged on one of the tool holders of the magazine wheels and transports the tool to the tool spindle and back.

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.

A tool magazine for tools of a machine tool for processing workpieces includes a first magazine unit that is close to a processing station of the machine tool and a second magazine unit that is remote from the processing station of the machine tool. The second magazine unit includes a permanent tool carrier and a temporary tool carrier. The permanent tool carrier is permanently accessible to a tool handling device. The temporary tool carrier is temporarily accessible to the tool handling device.

A machine tool setup changing method includes mounting a master workpiece onto a tool spindle axis, deforming a gripping part by gripping, with the gripping part of a jig, a mock clamped portion of the master workpiece mounted on the tool spindle axis, and removing the master workpiece from the tool spindle axis and mounting a tool supported on a tool support device onto the tool spindle axis, wherein the workpiece gripped at the clamped portion by the gripping part, which was deformed in accordance with the mock clamped portion, can be machined with the tool.

A fast tool changing method with pre-unclamping step for controlling operations of the spindle, tool unclamping cylinder, and tool changing arm. The spindle has one end clamping the tool at the clamping position. The method includes following steps. In a tool pre-unclamping step, the clamp end of the spindle moves the used tool to a pre-unclamping position; the tool unclamping cylinder pushes the used tool to leave a taper of the spindle. In a tool changing step, the tool changing arm rotates to clamp the used tool and pulls the used tool away from the clamp end, and further aligns a target tool with the clamp end. In a tool inserting step, the tool changing arm inserts the target tool into the clamp end, to be clamped therein. Therefore, the tool unclamping and tool clamping operations are accelerated.

A removable die of a joining tool comprising a die head having an upper side, a bottom side and a die shaft extending from the bottom side and receivable and lockable in a die dome without rotation. The die shaft comprises: at least one first radial web forming an axial undercut on two sides by which the die shaft is lockable in the die dome by a linear inserting movement, at least one second exposed radial web, the radial length of which is adaptable to a diameter of the die dome to ensure a lateral guiding of the die shaft in the die dome and which is arranged between the die head and the first radial web, and an ejection surface by which the removable die can be moved out of the die dome and which is arranged at the free end of the die shaft opposite to the die head.

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.
