Posted: March 12, 2018
Designed as a complete system, the Gundrill Grinder from UNISIG (Menomonee Falls, WI) comes equipped with all necessary software, hardware, high precision fixturing and measuring capability for concurrent grinding and measuring operations to ensure absolute process repeatability and accuracy, as well as faster speed in the overall gundrill grinding process. Whether resharpening existing points or generating new geometries, users can seamlessly move tool tips back and forth from the grinding wheel to the high power camera measuring unit, all while drills remain in their fixturing. Drills ground on this system last longer, provide better chip evacuation and create more precise holes as compared with those ground on other similar types of systems. The intuitive measuring software provides detailed, on-screen measurements. Other gauging system features include a digital 20X-90X extended-range magnification microscope, LED light and swing arm mounted digital depth micrometer.
The Gundrill Grinder can be fixtured to accommodate any range of gundrill diameters. The grinding head assembly, outfitted with a 220-grit diamond grinding wheel, delivers 360 deg adjustability, and fixture options for standard (sweep) and facet grinds are available. In addition to the Gundrill Grinder, UNISIG also offers their UNE Series of gundrilling machines that combine high performance and value in standard machine models that allow any shop to cost effectively add deep-hole drilling capability to their machining operations. Within the series are one or two-spindle machine configurations and several models for various maximum drilling diameters and depths. The UNE6 model drills diameters to 0.24 in (6 mm) and hole depths up to 10 in (250 mm), the UNE12 and 12-2 up to 0.5 in (12 mm) diameters and depths of 30 in (750 mm), and the UNE20 drills diameters up to 0.790 in (20 mm) at depths up to 30 in (750 mm).
