The present invention is an apparatus and method for replacing used electrode tips of a TIG welder. The apparatus has a main housing structure with a socket adapter assembly that is operatively supported by the main housing structure. The socket adapter assembly is used to both remove and re-attach the gas shield and the electrode nut of the TIG welder. A vacuum tip suction device that is operatively supported by the main housing structure is used to both remove and install electrode tips for the TIG welder.

The present disclosure relates to a tool holder to receive and lock a tool taper on a tool magazine, an unlocking device to unlock a tool taper that is received and is locked in a tool holder of this type, and a tool magazine for a machine tool comprising one or more tool holders of this type and an unlocking device of this type.

A thermal displacement correction method is provided, including a first step of setting an initial tool temperature, a second step of estimating a temperature of a tool or a position measurement sensor based on the initial tool temperature and a temperature of a spindle, a third step of estimating an amount of thermal displacement of the tool or the position measurement sensor with a preliminarily set tool thermal displacement estimation formula based on the estimated temperature, and a fourth step of moving a feed shaft of the machine tool based on the estimated amount of thermal displacement to perform a correction. In the second step, the temperature of the spindle is measured, then a tool-mounted portion temperature of the spindle is estimated from the measured temperature.

Disclosed is a gripping system for receiving a processing tool, and to a storage system. These processing tools are used in processing machines or centres in the woodworking industry. Also disclosed is a processing machine with the above-mentioned storage system. This processing machine is used for processing elongate pieces of wood.

A manufacturing system includes a base and multiple work machine modules that are attachable and detachable to and from the base arranged in the arrangement direction on the base or on the side of the base, in which the plurality of work machine modules include one or more processing work modules that perform machine processing work on a workpiece using a tool, and one or more supplementary work modules that perform supplementary work that is work supplementarily performed to the machine processing work. Since it is possible to easily increase and decrease the number of processing work modules and supplementary work modules or sort the modules, it is possible to easily recombine the modules with respect to modification of the manufacturing process.

An apparatus for interchanging welding tips of a spot welding gun. The apparatus replaces a welding tip installed in a robot arm and includes welding tip removal componentry combined with the robot arm, welding tip mounting structure combined with one side of the welding tip removal componentry, and a welding tip supply spaced apart from the welding gun at a specific distance and configured to supply a welding tip to the welding tip mounting componentry.

The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.

The present disclosure provides a nozzle cleaning device, a doctor blade replacing apparatus and a doctor blade replacing method. The doctor blade replacing apparatus includes a first doctor blade box, a second doctor blade box, a transferring assembly and a clamping and conveying mechanism. The transferring assembly includes a first tray which is disposed between the first doctor blade box and the second doctor blade box and a pushing assembly which is configured to push the first doctor blade in the first doctor blade box to the first tray and push the second doctor blade on the first tray into the second doctor blade box. The clamping and conveying mechanism is disposed between the first tray and the nozzle cleaning device for clamping and conveying the first doctor blade and the second doctor blade between the first tray and the nozzle cleaning device.

Tool magazine for the provision of tools for a machine tool, wherein the tool magazine has a multiplicity of receiving positions for tools. A first tool can be removed from or inserted into a first receiving position along a removal direction, and at least one further receiving position for receiving a further tool is provided.
