Guidewire Grinder: GT-9AC

The Glebar GT-9AC Automated Guidewire Grinder excels at precision grinding of medical guidewires with multiple tapers, paddles, and parabolic shapes with speeds as fast as a centerless grinder. Instead of using sensors to detect the wire position and trigger diameter changes, high-speed imaging technology and a 1-micron encoder run the entire length of the feeder providing constant updates displayed on the touchscreen HMI allowing for quick, simple adjustments. The result is crisp, clear tapers and virtually no limit to the number of tapers, paddles, and parabolic shapes which can be ground.
