Thrufeed Centerless Grinder: TF-9D
The Glebar TF-9D Infeed/Throughfeed Centerless Grinder uses computer controls to grind both hard and soft materials including catheters, medical guidewires, and spinal cord stimulators. Inside the compact footprint is a 7HP main spindle motor powering an 8.625 in wide work wheel combining to remove more material faster, and with better surface finishes, than similar machines with narrower grinding wheels. The TF-9D is designed to enhance productivity through a simple control interface and automation integration. Common applications include guidewires, catheter bodies, spinal cord stimulators, pins, and other engineered materials.
