MULTIPLE SMOOTH ELEMENTS BONDED TO A GROUND; NOVEL TOOLS AND METHODS FOR SURFACE IMPROVEMENT OF METALS AND OTHER MATERIALS
20180207766 · 2018-07-26 ·

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.

Brake conditioning

A wheel carrier assembly (104) for a vehicle (110) is clamped on a frame (14) and a carbon composite brake disc 41 of the assembly is bedded by pneumatically applying the brake pads to the brake disc so as to heat the disc in cycles, the wheel carrier assembly then being removed from the frame and fitted to the vehicle.

Burnishing head
09694471 · 2017-07-04 · ·

This invention concerns a burnishing head for smooth rolling of the ring-shaped flat end faces (3, 4) at the thrust bearing of crankshafts by means of two cylindrical burnishing rollers (1, 2) which are arranged to be rotated and are side by side in parallel to each other within a burnishing head housing (12) that is pivotable about its longitudinal axis (20) to reach its the working position. Each burnishing roller (1, 2) is pivoted in a cage (10, 11) which is provided in the burnishing head housing (12) with low play (13) and lateral relocatability.
