Wind Turbine

REM’s ISF®­­­ Process, an isotropic superfinishing process, brings a new standard of efficiency gains, extended component life and reduced part wear to customers in the Wind Turbine market. The ISF Process is capable of polishing parts weighing over 10,000 lbs./4,500 kgs.  The ISF Process offers the potential to finish multiple component features simultaneously (ex. gear flanks and integral bearing races) thereby reducing manufacturing costs.  The improved load carrying capacity of ISF Processed gears can offer increases in operating safety margins and/or design opportunities to increase power input or downsize components.  Lastly, the ISF Process is capable of turning used, damaged Wind Turbine Gears into better than new components via the removal of gear flank surface damage (up to ~0.003″/75 microns depending on available material stock). These refurbished parts outperform non-ISF processed new gears in terms of resistance to wear and contact fatigue. Request REM’s ISF Wind Turbine Gear Repair Selection Guide for detailed guidance on what damage types/gear failure modes are repairable.
