HPSF-The southern hemispheres market leader in isotropic super-finishing services and high end forged ceramic wheel polishing. REM isotropic super-finishing and shot-peening services, as well as receiving JDM Parts (30+ Business Days on Special Orders!). It would not be appropriate to treat those. DOD funded several studies including qualification testing for the AH-64 and CH-47, as well as coupon level testing of ISF and black oxide surfaces [3]. . Isotropic superfinishing is a customizable manufacturing operation whereby tens or hundreds of gears can be simultaneously processed in the same piece of vibratory equipment, or where a small number of highly critical gears can be processed in an isolated (compartment-based) fashion. These isotropic superfinishes achieve the highest performance ratings in terms of friction, heat, noise and wear in the bearing, gear, and turbine industries. This finishing process is widely used in racing applications where a conventional break-in process is not feasible, and where optimum. By: Martin McCormick. - isotropic superfinishing: extremely fine surface finish to boost the lambda value and reduce friction. Simply put, Isotropic Superfinishing significantly reduces the surface imperfections that remain after a Ring and Pinion Gear set is manufactured. This process is also called chemically accelerated vibratory finishing, where a highly active compound plays an essential role in the process.
