For a higher level of precision, consistency and repeatability, SUN Automation Group’s MicroGrind ® Die Cut Accuracy System hits the mark. For years, machine designers attempted to trim the anvil with several different methods. While those methods were effective, none have been as successful as MicroGrind. Sun’s MicroGrind system uses a tungsten carbide grinding roll to grind the anvil flat and true. This inventive idea allows the surface to be treated in micro amounts (0.001” or 0.025 mm) automatically with grinding precision every 10,000 impressions without operator intervention.
