GT-610 CNC: Infeed/Thrufeed Precision CNC Centerless Grinder

The Glebar GT-610 CNC Infeed / Throughfeed Precision Centerless Grinder is the complete “lights-out” solution for applications where a high degree of automation, data gathering, and gauging feedback is required. The fully automated system is capable of grinding and gauging multiple components per cycle. Challenging components such as arthroscopic shavers, bone drill blanks, and small powdered hard metal components can easily be processed. The GT-610 CNC excels in high production or frequent changeover operations with the assurance of automatic size compensation and 100% inspection. Common applications include aerospace fasteners, arthroscopic shavers, transmission bushings, small hard metal components, and more.
