Recent developments in grinding methods and superabrasive product technology have demonstrated improvements in productivity of over 40% on certain hydraulic components. Quality specifications for surface roughness and geometry can be achieved in a predictable and repeatable process. 3M will review data generated on popular carbide thermal spray coatings on aerospace and heavy equipment components, where as-sprayed surfaces were processed to finish specifications of 4 µinch Ra or better and geometry specifications of +/- 0.00025”. A new class of flexible Diamond abrasives designed for finishing wear resistant coatings will be described. Equipment requirements and operating parameters in production conditions will also be presented.
Summary: Advancements in grinding & finishing methods and superabrasive technology will be described, which yield reduction in total costs and provide significant improvements in productivity on a variety of thermal spray coatings.
