An edge-removing tool for sheet metal includes a head with a rotating cutting tool. The head has at least one guide for an edge. The head preferably includes a sleeve with the guide. The tool can be used to separate edges of an angled and/or welded sheet metal connection.

The invention relates to a stop for a rotating drilling, milling or countersinking tool which comprises a stop sleeve which is freely rotatably coupled, by means of a sliding or rolling bearing, around the tool. A first bearing bush of the bearing supports the stop sleeve. A second bearing bush of the bearing sits in a rotationally fixed manner on a shaft sleeve. The shaft sleeve can be pushed and fastened on a shaft of the tool. In a secondary aspect, the invention relates to a drilling, milling or countersinking tool having such a stop.

A router includes a motor assembly that is arranged and configured to hold a router tool and to impart rotation to the router tool and a frame that is fixed in size and that is configured to house the motor assembly.

A pipe milling machine for separating and/or cutting a pipe to length is disclosed. In an embodiment the pipe milling machine includes a milling wheel configured to separate the pipe and a motor configured to generate a feed of the pipe milling machine and to drive the milling wheel, wherein driving the milling wheel is independent of separating the pipe.

A method and apparatus for the refurbishment and repowering of wind turbines through the extension of existing installed blades so that they can catch more wind energy and therefore enable an increase in the overall average power output of the wind turbine.

An edge-removing tool for sheet metal includes a head with a rotating cutting tool. The head has at least one guide for an edge. The head preferably includes a sleeve with the guide. The tool can be used to separate edges of an angled and/or welded sheet metal connection.

The present invention is directed to a device that is removably secured to the exterior surface of a motor mounting plate to allow for milling of the mounting plate both in the field and off site. The adjustable attachment, positioning and securing frame of the device supports an operating frame that houses a travel mechanism and a cutting mechanism wherein a cutting tool attached to a cutting mechanism travels along a predetermined path, along and across the face of the motor mount plate, milling the surface of the motor mount plate true and flat.

Device for machining an end of an elementary panel for its subsequent friction stir welding, the elementary panel comprising a metal body defining two opposite faces, the machining device comprising a chassis, at least two guiding members configured to guide a first face of the elementary panel, at least one machining tool mounted on the chassis, the machining tool being positioned between the two guiding members and at least one pressure member mounted on the chassis and configured to exert a pressure on a second face of the elementary panel so as to press the elementary panel against the guiding members along the horizontal reference direction.

A power tool including a housing and a motor assembly arranged to rotate a cutting tool. The motor is mounted in the housing. At least one guide post is slidably mounted to the housing. The power tool includes a base fixed to the guide post. A depth adjustment mechanism is arranged to adjust the distance the cutting tool projects through the base. The depth adjustment mechanism has a depth rod adjustably mounted to the housing and arranged to engage the base when the housing is plunged towards the base. The depth adjustment mechanism also has a depth adjustment knob mechanically coupled to the depth rod and moving the depth rod with respect to the housing. The depth adjustment mechanism further has a locking knob for selectively locking the depth rod. One of the depth adjustment knob and the locking knob at least partially is nested within the other.

A chamfering device includes: a main body including, at a proximal end side thereof, a shank to be attached to a main shaft of a machine tool, the main body including, at a distal end side thereof, a shaft portion extending in a rotational axis direction; a movable body whose proximal end portion is mounted to the shaft portion, the movable body being configured to rotate together with the shaft portion and be movable in the rotational axis direction; an urging member configured to urge the movable body in a direction toward the distal end of the main body; a chamfering tool mounted to a distal end portion of the movable body and configured to rotate together with the movable body to perform chamfering on an edge portion of a workpiece; and a following member mounted to the movable body such that a position of the following member relative to the movable body in the rotational axis direction is invariable and the following member is rotatable relative to the movable body, the following member being configured such that a distal end thereof comes into contact with a surface of the workpiece.
