after execution of the cleaning process, to bring the holding unit (18) and at least one further cleaning region (24) of the reprocessing unit (16) together for an execution of a further cleaning process.

A machine tool includes a camera fixed to a predetermined imaging area and for imaging a tool inserted into the imaging area, a tool holding portion to which a tool is attachable, and a machining control portion for controlling the tool holding portion in accordance with a machining program and machining a workpiece with the tool. The machining control portion moves the tool toward the imaging area after rotating the tool to image the tool.

A machine tool includes a spindle including a tool insertion portion having a shape of an opening into which a shank of a tool is inserted and configured to attach the tool thereto, a tool change unit configured to change the tool attached to the spindle while gripping the tool, an air supply unit configured to supply air to a gap between the tool insertion portion and the shank of the tool when the tool change unit changes the tool, and a controller configured to control driving of at least any one of the spindle and the tool change unit to allow the tool and the tool insertion portion to reciprocate relative to each other in a predetermined direction with the shank of the tool inserted into the tool insertion portion and with a gap provided between the tool insertion portion and the shank of the tool.

The present disclosure relates to an engine-driven tool (1) comprising a rotatable work tool (2), an engine (4) that is arranged to propel the rotatable work tool (2), a shielding cover (8) for shielding the rotatable work tool (2), and a dust channel (11) that is formed between the shielding cover (8) and the rotatable work tool (2). A dust hose (14) is arranged to connect the dust channel (11) to a dust container (17) and an electrically driven fan (16) that is arranged to convey air from the dust channel (11) into the dust container (17) via the dust hose (14). The engine-driven tool (1) comprises an electrical generator (18) that is electrically connectable to the fan motor (26) and is arranged to be at least indirectly driven by the engine (4). The electrical generator (18) is furthermore arranged to generate an electrical current when driven, where said electrical current at least indirectly is arranged to propel the fan motor (26).

An apparatus for converting elongate stringy turnings from a workpiece being machined to short chips. There is an endless conveyor carrying grapples to grab the stringy turnings and move them along the length of the conveyor and then preferably to a metal chipper assembly which converts the stringy turnings into short chips.

An accessory for a hand-held power tool has a first air channel and a second air channel. In the first air channel, a first air stream for transporting dust particles is routed into a dust-collecting box. In the second air channel, a second air stream for transporting dust particles into the dust-collecting box or into a further dust-collecting box is routed.

A tool changer is used for changing tools in a machine tool. The tool changer has a support structure on which a lifting carriage is guided along a vertical lifting direction. A pivot arm is pivotably mounted to the lifting carriage about a vertical pivot axis. A plurality of tool holders arranged vertically one above the other form a tool magazine. A tool gripper is attached to the pivot arm. The tool gripper grips a tool. The tool is subsequently moved between one of the tool holders and the tool spindle of the machine tool by a combined lifting and pivoting movement of the pivot arm. Optionally, an auxiliary arm pivotably attached to the pivot arm can be used to change a workpiece clamping means of the machine tool.

A reprocessing apparatus, in particular a cleaning and/or preserving apparatus, for tools, tool holders and/or tool units is proposed, with at least one reprocessing unit, in particular for a reprocessing of used and/or contaminated tools, tool holders and/or tool units, with at least one holding unit for an exchangeable holding of the tools, tool holders and/or tool units, and with at least one handling unit which is configured, for an execution of a cleaning process on the tools, tool holders and/or tool units, to bring the holding unit and at least one cleaning region of the reprocessing unit together in an at least semiautomated manner, and after execution of the cleaning process, to remove the holding unit and the cleaning region of the reprocessing unit from each other in an at least semiautomated manner, and/or after execution of the cleaning process, to bring the holding unit and at least one further cleaning region of the reprocessing unit together for an execution of a further cleaning process.

A tool cleaning device for a machine tool has a chip removing device which removes the chip, a moving device to which the chip removing device is attachable, a detecting device which detects a storing state of the chip to the tool of the machine tool, an information processing device which processes information according to the storing state of the chip acquired by the detecting device and judges a region where a chip removing is necessary, and a controller of the moving device which moves the chip removing device to the region where the chip removing is necessary judged by the information processing device. The chip stored on the tool is cleaned by the chip removing device.
