The invention relates to a processing plant (1) comprising: at least one first working spindle (2); a tool magazine (6) for storing different processing tools (4), wherein at least one storage plane (10) having several tool receiving spaces (11) arranged next to one another is provided in the tool magazine (6); a tool change device (5) comprising at least one first gripper device (13) for exchanging the processing tool (4) held in the working spindle (2), wherein the gripper device (13) comprises at least one first gripper unit (15) and one second gripper unit (16) which are positioned at a gripper-unit distance (17) from one another. The gripper units (15, 16) can be displaced between the working spindle (2) and the tool magazine (6).

A machine tool includes a tool spindle, a tool intermediate device, and a tool storage which includes first tool magazines, a first tool magazine support mechanism, an additional first tool magazine support mechanism, and a tool carrier. The first tool magazine support mechanism includes a first shaft to support at least one of the first tool magazines to be rotatable about a first rotation axis. The additional first tool magazine support mechanism includes an additional first shaft to support at least one of the first tool magazines to be rotatable about an additional first rotation axis. The tool carrier includes a first guide extending along the first and additional first rotation axes, a second guide extending along a line connecting the first and additional first rotation axes, and a lift configured to move along the first guide. The first guide is movable along the second guide.

A tool exchange device for tool magazine includes a base having a driving member, a pressure cylinder, a movement member pivotally connected to the base adjacent to the driving member, and a tool retrieving member disposed on the movement member. The driving member has a connection portion and a twisting portion. The pressure cylinder has a piston rod pivotally connected to the connection portion for driving the driving member. The twisting portion is removably received in a receiving portion of the movement member. With the rotation of the driving member, the twisting portion forces the movement member to move along an arc shape route, such that the movement member rotates by an angle, and the tool retrieving member sways between a vertical and horizontal positions. Therefore, the tool exchange device is driven with a lower force, and the tool retrieving tool stably sways.

A cutting blade supplying apparatus includes a cutting blade stocker that stocks a plurality of cutting blades, a carrying unit that carries out the cutting blade from the cutting blade stocker and carries the cutting blade to a cutting apparatus, a transferring unit that transfers the cutting blade carried by the carrying unit to a blade replacing unit of the cutting apparatus, and a control unit. The control unit selects the cutting blade needed by the cutting apparatus and causes the cutting blade to be carried by the carrying unit to the cutting apparatus.

A tool magazine includes a magazine arm and a gripper plate. The magazine arm has a tool pot to hold a tool. The magazine arm is pivotable around a pivotal axis such that the tool pot pivots around the pivotal axis. The gripper plate has at least one gripper to hold the tool at a holding position on a circular arc track along which the tool moves when the magazine arm pivots. The at least one gripper is open in a tangent direction of the circular arc track at the holding position.

A cutting blade supplying apparatus includes a cutting blade stocker that stocks a plurality of cutting blades, a carrying unit that carries out the cutting blade from the cutting blade stocker and carries the cutting blade to a cutting apparatus, a transferring unit that transfers the cutting blade carried by the carrying unit to a blade replacing unit of the cutting apparatus, and a control unit. The control unit selects the cutting blade needed by the cutting apparatus and causes the cutting blade to be carried by the carrying unit to the cutting apparatus.

A movable fixture for milling rail heads of slide rails arranged in a track bed includes: a rotating milling head mounted in a milling head drive mechanism supported by a chassis. The milling head has at least one cutting tooth comprising several cutting plates for milling the rail heads and a disc-shaped tool carrier connected to the milling head drive mechanism. The tool carrier includes cassettes assembled with cutting plates arranged around their periphery. The cassettes are arranged in several carrier segments connected to the tool carrier so they can be detached. The cassettes are arranged peripherally on the tool carrier with at least two assembled cutting plates, the cassettes being different with regard to at least one of: a number of cutting teeth; distances of the cutting teeth from each other; rake angle of the individual cutting plates; or inclination angle of the individual cutting plates.
