[Video Now Available] What is buffing? Buff Grandpa's Artisan Skills Part 1 - Polishing Mysterious Items!

ユー・コーポレーション ユー・コーポレーション
Acrylic (PMMA) and polycarbonate (PC) tend to whiten and become cloudy on the surface when machined. However, by using a buff polishing method for mirror finishing, we can reproduce a clearer transparency! Our skilled technicians perform buff polishing by hand, and our customers have praised the high quality of our work. If you are having trouble with mirror finishing on resin products, please feel free to contact us. *Please watch the video on buff polishing at the URL below! At You Corporation, we achieve ultra-precision machining in the micron order using our years of accumulated know-how and high-precision equipment environment for both resin and metal materials. We handle various types of resin machining, such as PC, acrylic, PPS, and PEEK, as well as metal machining for stainless steel, titanium, Inconel, and Kovar at our own factory. If you have any difficulties with complex shapes, tight deadlines, or cost issues, please consult with us!
