Wet Blasting Technology, Part 3

Numerous technical features combine to make wet blasting an effective method of surface finishing. When expertly combined by an experienced finishing expert such as Rosler, this method can achieve precise and repeatable results on a variety of work pieces from a wide range of industries. A general understanding of the essential technical elements of a wet blasting machine will help you select a machine for your specific needs as well as prolonging the efficiency and life of existing wet blasting equipment.

Mass Finishing

Mass finishing processes are effective because the motion of media against work pieces transforms the surface of the work pieces. The deflashing, descaling, edge rounding, polishing/smoothing, cleaning/oil removal/degreasing, and/or grinding effects change the surface of the media itself along with the work pieces. As a result, media wears down over time, losing its shape, size, and effectiveness. Known as undersized media, this worn media must be discharged and replaced with fresh media to ensure proper processing and safety. Whether a process uses ceramic, plastic, or polishing and drying media, Rosler stresses the importance of monitoring media levels and the mix of new and worn media for precise and safe mass finishing results.

The aerospace industry demands high repeatability and adherence to strict production tolerances. As we discovered in Aerospace, Part 2, Rosler Metal Finishing’s drag finishing systems produce exact results every time. Airbus Helicopters After using Rosler drag finishing systems for a number of years, Airbus Helicopters knew just who to turn to for help with a new helicopter model. We took on the challenging task of finishing larger gear components for the new design as well as incorporating expanded capacity for their existing helicopter models, developing an innovative drag finishing system with automatic work piece clamping and a clever work piece handling system. Based on numerous processing trials in our test center, Rosler developed an entirely new drag finishing concept that meets all customer requirements. Flexible yet robust, the new drag finisher is capable of finishing approximately 35 different work pieces made from special, high-performance steel alloys with diameters from 40-800 mm and individual weights of up to 75 kg.

Wet Blasting 2

Unlike dry blasting in which only solid abrasive media is used, wet blasting processes use a slurry in which the media is embedded in water. This greatly cushions the impact energy on the work pieces, providing gentler, yet effective results for delicate work pieces. As the utilization of wet blasting increases, Rosler reminds manufacturers to review their traditional, dry shot blasting applications and consider if wet blasting could provide additional efficiencies, reduced costs, and better results. Understanding the Differences Visual comparison of wet, dry shot, and dry grit blastings' impact on surfaces As in any surface finishing process, the starting condition of the work piece, its material composition, shape, and final finish largely dictate which finishing application is most appropriate. Understanding how the application changes the work piece is a key consideration.. Weiterlesen [...]
