Unisig’s Gundrill Grinder enables concurrent grinding and measuring operations to help ensure process repeatability and accuracy while speeding the gundrill grinding process. According to the company, users can seamlessly move tooltips back and forth from the grinding wheel to the grinder’s high-power camera measuring unit while drills remain in their fixturing. Additionally, drills ground on the system are said to last longer, create more precise holes and provide better chip evacuation.

The machine’s grinding head assembly is equipped with a 220-grit diamond grinding wheel and delivers 360-degree adjustability. The grinder’s measuring software provides detailed on-screen measurements, and other gaging features include a digital 20× to 90× extended-range magnification microscope, LED light and mounted swing-arm digital depth micrometer. The company says it can fixture the grinder to accommodate virtually any range of gundrill diameters, and options for standard (sweep) and facet grinds are also available.
