Whether your goal is deburring, polishing, edge preparation, or surface preparation for coatings, our team develops customized processes to deliver optimal performance. We adapt our technologies to meet your part specifications, ensuring consistent quality and efficiency.
To guarantee superior results, we provide free sample processing. Our advanced metrology tools, including non-contact 3D white light interferometry, measure and document before-and-after surface data. Our detailed metrology report includes 3D imagery and Ra and Sa surface roughness values, offering full confidence in the process.
Once you are satisfied with the results, we quote the necessary equipment, media, and compounds to replicate the process at scale. We also offer post-sale support, including media replenishment, maintenance, and process optimization, ensuring your finishing system continues to meet evolving production needs.
