The Moore Tool Co. (Bridgeport, C T) H-500 CPWZ jig grinder handles both wet and dry grinding of holes and contours and work in four axes simultaneously. It features a hydrostatic main spindle for ultra-round holes and contours, and a GE Fanuc 180i-MB CNC control with a PC front end. During recent beta tests, the grinder consistently held roundness within 10 micro inches (0.000010 in., 0.00025 mm) and linear accuracy within 50 micro inches (0.000050 in., 0.00012 mm.). These accuracies are reported to be more than three times better than anything achieved with the best available technology today.
