A device (1) for exchanging at least one cutting component (2a) of a rotating tool (2), in particular a milling tool (2), and more particularly, a hollow milling tool for machining workpieces made of plastic. The device has an aligning device (5) for orientating a position of the cutting component (2a) relative to a rotational axis (2c) of the tool (2) and an exchanging device (6) for releasing the cutting component (2a) from a part (2b) that remains on the tool (2) and for attaching another cutting component (2a) to the part (2b) that remains on the tool (2).

A cutting apparatus includes a blade changing unit demounting an old cutting blade from a blade mount and mounting a new cutting blade to the blade mount. The blade changing unit includes a blade holder for holding a support base of each cutting blade and a moving portion for moving the blade holder in the axial direction of a boss portion of the blade mount in the condition where each cutting blade is held by the blade holder, thereby mounting the new cutting blade to the boss portion or demounting the old cutting blade from the boss portion. The cutting apparatus further includes a control unit controlling the blade changing unit. The control unit measures a signal indicating a force applied to the moving portion in mounting or demounting, and determines the condition of the blade changing unit and blade mount according to the signal measured by the measuring portion.

This machine tool is provided with: a partition that partitions a machining chamber and a tool storage chamber and that has an opening; a shutter; and a receiving member that is formed so as to receive cutting fluid. The partition includes a sidewall member that extends in the vertical direction and an inclined wall member inclined in such a manner so as to become lower from the sidewall member to the interior of the machining chamber. At least part of the opening is formed in the inclined wall member. The receiving member is positioned beneath the shutter, and in such a position so as to receive cutting fluid that drops down along the sidewall member when the shutter is opened.

A machine tool includes a base, a table, a main spindle, and a trunnion unit. The table is installed on the base. A tool is mounted to the main spindle. The main spindle is caused to approach a workpiece on the table along an up-down direction. The trunnion unit is configured to rotatably hold the table on which the workpiece is placed using a rotation axis along a front-rear direction as a center. The trunnion unit is disposed movable in a right-left direction.

The present disclosure relates to a device for attaching and detaching tools in a magazine, and more particularly, to a device for attaching and detaching tools in a magazine of a machine tool, the device being capable of attaching or detaching a tool having directionality to or from each gripper of the magazine of the machine tool while accurately adjusting a fixed position of the tool.

A gripping device, rock drilling unit and method of gripping drilling tools is disclosed. The gripping device includes a frame and at least one elastic gripping element connected in a fluid-tight manner to the frame. The gripping element may be expanded by conveying pressurized fluid between surfaces of the frame and the gripping element, whereby the gripping element moves against surfaces of the drilling tool and generates friction forces and support.

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 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.

This machine tool is provided with: a partition that partitions a machining chamber and a tool storage chamber and that has an opening; a shutter; and a receiving member that is formed so as to receive cutting fluid. The partition includes a sidewall member that extends in the vertical direction and an inclined wall member inclined in such a manner so as to become lower from the sidewall member to the interior of the machining chamber. At least part of the opening is formed in the inclined wall member. The receiving member is positioned beneath the shutter, and in such a position so as to receive cutting fluid that drops down along the sidewall member when the shutter is opened.

A machine tool, which has a tool magazine for storing multiple tools and is for machining a workpiece with a tool held on a main shaft by moving the main shaft relative to the workpiece, wherein the machine tool is provided with: multiple feed shafts for moving the tool relative to the workpiece; a tool magazine drive motor for driving the tool magazine; and a manual pulse generator, which is for sending a positive or negative command pulse to the multiple feed shafts or tool magazine drive motor, the manual pulse generator being provided with a selection switch for selecting one of the multiple feed shafts or the tool magazine drive motor as the destination to which the command pulse is to be sent.
