Burnishing Machines TRIZ Cases

Impact media in a reactive fluid form solid lubricant on complex surfaces, improving adhesion and low-friction retention without post-machining.

A spring-biased spherical roller applies static load while rolling smoothly, reducing skidding and driving compressive stress below the surface.

An offset-arm roller tool deep rolls complex blade roots without hydraulics, speeding machining while inducing compressive stress for longer fatigue life.

Piezo-driven pressure pulses create uniform indentations on metal sealing surfaces, improving wear resistance and sealing effectiveness.

A smooth mandrel plus spinning and burnishing lowers fixing sleeve inner-surface roughness, improving thermal conduction and thin-wall manufacturability.

Real-time adjustment of pressure, current, and feed rate keeps ultrasonic roller burnishing stress within the target range across workpiece areas.

A convex smoothing element matches the target contour to finish cone sections, punctures, and corners without rounding or distortion.

A rotating flexible line with clustered peening elements reaches confined surfaces while simplifying manufacture and improving peening control.

Fluid pressure drives opposed burnishing wheels into thread roots, simplifying setup while avoiding net force and custom support structures.

A pivoting holder arm replaces straight-line roller motion, reducing adjustment resistance while preserving base body strength and alignment.

A radially movable knife holder keeps the cutting edge stable and counters passive forces, improving cylinder peeling on curved hot-rolled pipes.

Real-time motor power feedback adjusts burnishing depth, pressure, current, and feed rate to control area-specific residual compressive stress.

Housing vibration drives shots inside the workpiece to raise internal compressive residual stress without the roughness limits of larger or faster particles.

Laser welding joins stainless steel hemispherical shells without filler metal, eliminating porosity and material loss from traditional MAG processes.

Asymmetric cylindrical features prevent inverted mounting of hard-rolling rollers, ensuring correct deep rolling force distribution on crankshafts.

Replacing hydraulic transmission with rigid gears eliminates leakage and positioning fluctuations during workpiece surface smoothing.

A portable automated peening device uses a programmable logic controller to adjust axial and circumferential slide assemblies for precise positioning.

Dual rolling elements prevent grain detachment during cylinder surface machining by applying controlled pressure.

Segmented burnishing components on a tapered cam shaft apply pressure to remove burrs from plastic containers without generating chips or dust.

Replacing hydrostatic bearings with a polymer bearing eliminates fluid supply needs while maintaining controlled burnishing force.

Axial guide rollers engage crankshaft oil collars to stabilize deep rolling units, eliminating axial vibrations caused by long lever arms.

Multiaxial vibration peening creates uniform compressive residual stresses by controlling impact density and intensity.

A tool head follows a virtual control surface to induce compressive residual stress on irregular workpieces.
