An adjustable stroke mechanism has a housing with a central axis and a wall enclosing a cavity. At least one counterweight is movably disposed within the cavity. A mounting assembly is disposed within the cavity. The mounting assembly has a workpiece attachment mechanism. A stroke adjustor couples the at least one counterweight with the mounting assembly. The stroke adjustor enables the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.

The invention relates to a device with a machine tool and a braking device, the machine tool having an eccentrically supported, rotatable backing pad for receiving a tool. According to one embodiment, the braking device has a frame, which is attached to the machine tool; a spring, a first end of which is fixed on the frame; and a lever, which is connected to a second end of the spring. The braking device also has an actuator, which is designed to move the lever, wherein in the event of a movement of the lever, the spring is compressed and a part of the lever is pressed against the backing pad of the machine tool.

A cooling device for a rotating machine has a fan assembly coupled with a backing plate. A hub, on the backing plate, secures the cooling device with a shaft. The backing plate includes one or more vents to enable air to exit the cooling device. The fan includes an opening to enable air to enter the cooling device. A chamber is formed between the fan assembly and the backing plate. During rotation, air is drawn into the opening. The air is passed into the chamber and exits through the vents to cool a work surface or working pad attached to the backing plate.

A machine tool system includes at least one portable machine tool and at least one energy storage apparatus. The at least one portable machine tool includes at least one tool receptacle configured to be arrange a machining tool, and at least one receiving interface. The at least one energy storage apparatus is configured to be arranged on the at least one receiving interface of the at least one portable machine tool. At least in a state when the at least one energy storage apparatus is arranged on the at least one receiving interface, the at least one energy storage apparatus is arranged at least for the most part within a boundary region of the at least one tool receptacle.

A method and apparatus for deburring a metallic surface is disclosed. The method and apparatus utilizes a handheld orbital sander that is compact so that machine marks disposed in tight places can be reached. Additionally, a conformable sanding pad is utilized to allow the sanding pad to conform to the unique contours of the metallic surface to eliminate the machining marks.
