According to one implementation, an attachment for a machining apparatus includes: a copying guide in a machining apparatus side and an air supply passage. The copying guide has a through hole for passing a tool through. The copying guide is contacted to a copying mold placed in a workpiece side. The copying guide is attached to a spindle holding and rotating the tool. The air supply passage is adapted to supply air ejected toward the workpiece side through a clearance between the tool and the through hole.

Cutting tools for pipe cutting frames are disclosed. Example split frame pipe cutting tools include a frame and a slide tool configured to position a cutting edge in contact with the workpiece to performing cutting or boring on the workpiece, the slide tool comprising: a radial advancement mechanism configured to provide radial advancement of the cutting edge based on circumferential advancement of the slide tool by the frame; and an axial guide rail; a recirculating bearing carriage configured to slide in an axial direction along the axial guide rail and to couple the cutting edge to the axial guide rail; an axial advancement mechanism configured to advance the cutting edge in the axial direction with respect to the workpiece by translating radial advancement by the radial advancement mechanism to axial advancement based on a cutting template coupled to the radial advancement mechanism.

A method of machining an attachment flange of an aircraft turbomachine case, the method also including a system to machine the two opposite surfaces of the flange, and including a shape follower machining module, this module being designed to follow the shape of the flange and including a first structure equipped with a first machining tool, and a second structure equipped with a second machining tool, the flange fitting between the structures such that its two opposite surfaces are machined by tools, the module also including shape follower elements carried by the structures; and a device to drive movement of the machining module along a circumferential direction of the flange.

A power tool including a housing mounted to be moveable with respect to, and spaced from, a base, said housing including a motor to rotate a shaft which includes, at its free end, a tool holder for a tool, said shaft extending from the housing such that the tool holder is located at or adjacent to the base and can pass through an aperture in said base, said housing connected to the base by one or more support assemblies, and a sleeve provided to be positioned on the base and form therein an area in which the said tool and aperture in the base are located when performing work on a workpiece. Dust extraction apparatus can be connected and the base can be selectively provided with guide means and also includes attachment means to allow the power tool to be selectively located with a worksurface or a guide plate.

Devices, kits, and methods for making a carved crayon are provided. In one aspect, a crayon carving device includes a base, a pantograph armature coupled to the base, a crayon positioner, and at least one guide template parallel to the crayon positioner. The pantograph armature includes a motorized drive shaft with a drill tip for carving an outside surface of a crayon body, as well as a guide tip for tracing along a guide template that directs where the drill tip carves. In some embodiments, the guide template includes a stationary bridge support and a plurality of removable carving bucks that insert into one of multiple openings on the bridge support. The surface features of each of the carving bucks may be traced by the guide tip to generate a corresponding carving on the surface of a crayon body.
