PATENTED SILICON NITRIDE CMM STYLI On August 23, 2003, the United States Patent and Trademark Office awarded a US Patent to Q-Mark Manufacturing, Inc. for Drilled Silicon Nitride Balls used in coordinate measuring machine (CMM) styli. Each year, Q-Mark manufactures and delivers thousands of these innovative, high-productivity tools to CMM users worldwide. Q-Mark’s drilled silicon nitride balls are extremely hard (78 Rc), have a lower coefficient of friction than ruby balls, and have highly polished surfaces. Q-Mark’s silicon nitride styli exhibit less tendency to accumulate material on their surface, and better wear resistance than ordinary ruby ball styli. Scanning CMM users report up to 5 times longer tool life using Q-Mark’s drilled silicon nitride balls in place of ruby balls. Q-Mark offers drilled silicon nitride styli in ball sizes from 1 mm to 12 mm diameter. Our free 68-page M5 stylus catalog features hundreds of CMM styli with drilled silicon nitride balls. A free sample of a Q-Mark drilled silicon nitride stylus is available to CMM users. Call 800-776-2388 for more information. |
