We specialize in the manufacturing of Aircraft Quality Hardened and Ground Gears, as experts in bevel gear manufacturing, including Flight Safety Critical Parts. With applications in Formula 1, NASCAR, Indy Racing, SCCA Racing, Open Wheel Cart Series, and many other racing series, REM is the pioneer of surface finishing/polishing for the Racing/Motorsport industry and the company you should trust to deliver the quality you need. This paper discusses using a non-abrasive, high density media in conjunction with an isotropic superfinishing (ISF) chemistry. GIANT FINISHING, INC’S Post GIANT FINISHING, INC 468 followers 2yProviding Vibratory, Isotropic Superfinishing, Abrasive Blast, Shot Peening & Industrial Washing Solutions 1y Report this post Garrett and the team have been super awesome to deal with!. By a judicious choice of media and a chemical accelerator, the hypoid gearsets can be superfinished in less than five minutes to an Ra of less than 0. 25 µm or nominally 10 µin can be defined as having a superfinish. This study showed isotropic superfinishing technology increased a gear’s resistance to contact fatigue by a factor of three, and increased bending fatigue resistance by at least 10 percent. “When you turn or grind a part, the depths of cut could range from 50-100 microns or higher,” Keshavan says. HPSF-The southern hemispheres market leader in isotropic super-finishing services and high end forged ceramic wheel polishing. However any parts can be Superfinished that are not already coated like some wrist pins that come DLC coated. 6 Poon and Bhushan7 demonstrated the influence of the resolution of the applied measurement equipment . This paper presents performance test results on specimens and gears finished with a patented chemically accelerated vibratory finishing process10 referred to as the Isotropic Superfinish (ISF) process. This paper discusses using a non-abrasive, high density media in conjunction with an isotropic superfinishing (ISF) chemistry. Kotouč Gearboxes was one of the pioneering companies using the revolutionary super finishing process from REM on racing gearbox components before it became more popular throughout the racing industry as you see today. The Carbon Edition package for the Tremec TKX 5 speed will include: Custom aerospace polymer fork pads that can withstand more heat and friction than the best brass or bronze pads will endure for a more consistent and crisp shift.
