Deburring & Finishing
Nitinol, titanium, tungsten carbide, aluminum, brass, Kovar, PEEK, stainless steel, Delrin, and others. For high-production applications, micro-abrasive blasting can be integrated into semiautomated systems.
Mass Finishing is “Finding a Better Way”
“More and more automation is being included in our tradi- tional rotary vibratory bowl or vibratory tubs processing, often combining material handling and drying,” said Tim Gibson, general sales manager, Rosler Metal Finishing (Battle Creek, MI). “When we discuss a possible solution with our custom- ers we want to know the scope of the program, what’s the throughput, whether deburring, polishing or smoothing a part, or descaling is involved. Looking at the geometry of the part helps us marry a mass finishing vibratory process, whether it’s drag finishing, traditional tumbling, or high-energy disk ma- chining to the solution. We also offer shot blasting equipment, on the other side of the business,” said Gibson.
“A deburring or finishing solution includes equipment, au- tomation, and consumables. We manufacture the consumable media, which people call stones, in Battle Creek. Media can be as diverse as ceramic, plastic, steel, and even glass beads, and include the soap and compound. Selection depends on the requirements of the part being processed. Our mass finishing equipment comprises rotary vibrators, tub vibrators, high-energy disk machines, which are typically 10 times more aggressive than the standard bowl, and drag machines which are 40 times more aggressive than a standard bowl. The drag machines are used for applications where sensitive parts can’t touch one another and we’re trying to remove a lot of mate- rial,” said Gibson.
“Mass finishing or shot blasting has been around for years.
We continuously make improvements to the features of our equipment, but the biggest advancements are coming from the consumable side of the business where the media and the com- pounds are getting more and more advanced in terms of cutting performance, or wear performance, as well as preventing rust. One piece of new equipment is a wet blaster with an air- driven nozzle that shoots media, like glass beads, that are basically carried by water and cushioned when hitting the part, so you have no impingement. This equip- ment has made inroads in processing medical implants,” said Gibson. ME
