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” 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.
