Taper ring gage 1:30 for 219.2 ± 0.015

The technical specifications speak for themselves and show the variety of requirements and challenges a gage manufacturer must be able to control. An angle of 0°56'17˝ ± 5˝ with a surface finish of Rt <3, an outside diameter of 290.00 mm / 260.00 mm, a length of 192.00 mm and a weight of approximately 37 kg, that’s something to cope with indeed. To mount a cone of that weight for grinding with the required precision is challenge enough.
