Overview

Roller Burnished surface are smoother and more wear-resistant than abraded surfaces. Abrasive finishing processes remove metal by cutting or tearing it away. Roller burnishing processes displaces metal rather than removing it thereby creating a smoother surface than an abraded surface. Roller burnished surfaces last longer under working conditions than abraded surfaces
.... Cost-Effective ! 

Roller Burnishing tools can be used on lathes, drill press machining centers or any rotating spindles with either tool or part rotating. Any ductile or malleable material like cast iron, Aluminum Steel, Stainless, Alloy, Copper, Brass, Bronze, virtually any material (hardness <40 Rc) can be sized obtaining surface finish as high as 0.2 Ra with 5% to 10% or more increase in tube surface hardness and improving the fatigue life as much as 300% or better in One Single Pass

Tristar Roller Burnishing tools are already burnishing internal / external diameter & taper/flat faces. These tools are used in the manufacture of components for automobiles, piston & oil engines, textile machinery, material handling equipments, gears, motors & pumps, pneumatic & hydraulic Cylinders, valves, fluid control equipments, precision components etc.

Single roller multi-purpose tools to burnish external diameters & grooves are also manufactured.
