An electromagnetic hammer device adapted to provide non-contact mechanical treatment of a material in planar items, cylindrical items, or tubular items including a conductor provided along a predetermined path within the material being treated and being supplied with a first pulsed current and a second linearly configured conductor or V-shaped conductor or conductive tube lined on top of conductor and being supplied with a second pulsed current, a layer of insulating material being lined intermediately between the first and second conductors. The simultaneous application of the first and second pulsed currents in the same direction results in exerting tensile forces onto the material and application of the currents in opposite directions results in exerting compressive forces therein. A pair of auxiliary conductors is preferably provided in each side of the second conductor, which provides adjustment of the angle in which the tensile or compressive forces are applied. A method for the mechanical treatment of a material using the hammer device.

Embodiments of the present disclosure provide surface treatment tools, methodologies, and/or repaired turbomachine components. A surface treatment tool according to the present disclosure can include a lathe assembly having a lathe chuck for receiving a component thereon, wherein the lathe chuck rotates the component about a first axis of rotation, and wherein the component includes an exposed axial target surface; and a sander or burnishing tool coupled to the lathe assembly and including a sanding or burnishing surface thereon, coupled to a drive system, wherein the sanding or burnishing surface rotates about a second axis of rotation substantially non-parallel with the first axis of rotation, such that the sanding or burnishing surface selectively contacts the target surface of the component to yield a polished target surface.

The invention relates to a tape drive, which may include a transport mechanism which may include a tape head. The tape drive may be adapted to receive a magnetic tape with the transport mechanism, and to transport the magnetic tape by the transport mechanism. The tape head may be adapted to perform read-write operations on an oxide side of the magnetic tape. The tape drive may include a burnishing unit, which may include a burnishing roller and a burnish controller having an abrasive shell. The burnishing roller may be installed in the tape drive upstream of the tape head such that the abrasive shell supports the received magnetic tape on the oxide side. The burnish controller may be adapted to control the movement of the burnishing roller.

A burnishing tool uses a relatively small pressing load in burnishing. The burnishing tool for machining a target surface of a workpiece includes a base and a tip portion located on a distal end of the base. The tip portion includes a linear slide-contact portion that linearly contacts and slides on the target surface.

A machine for processing a screen printing frame includes an upstream end and an opposed downstream end, a grinding assembly located between the upstream and downstream locations, wherein the grinding assembly includes a first grinder configured to grind a first pattern into the screen printing frame and a second grinder configured to grind a second pattern into the screen printing frame different from the first grinding pattern.

The Present Invention introduces novel methods and tools for improving the surfaces of metals and other flowable materials with smooth-surfaced tools, such as fibers and spheroids bonded to a ground. The new tools deform and compress rather than remove material, thereby increasing surface hardness, density, reflectivity, electrical conductivity, impermeability and corrosion resistance. Benefits include economies in production and maintenance, an improved work environment, and reduced costs for energy, stock materials and precious metal reclamation.
