In-house inspection proves machining capabilities for precision manufacturer.
For a number of years, the GCH Group out of Warren, MI had successfully used outside resources for their quality inspection and reverse engineering needs. Now they wanted to bring precision inspection in house to reduce machine setup and run-off times, and more importantly to prove that their machining capabilities were top-notch. With a lot of custom parts having target tolerances in the micron and submicron range, they were looking for automated inspection systems that could perform various types of measurements with high accuracy and fast throughput.
The GCH Group needed these quality inspection systems for two of their divisions: the machinery division that provides re-manufactured grinding solutions and the tool group that provides a dependable source for new spare parts and assemblies for machinery. Reverse engineering and quality inspection were needed for the tool group and the machinery division needed to qualify incoming parts and measure parts for machine run-offs. Since most of the machines the GCH Group produces grind round and flat parts, they also needed to measure cylindricity, roundness, squareness and flatness. Machine surface finish inspection was also required. They check waviness, profiles, radiuses and surface finish, meeting customer specifications to print.
