Technical Booklet

Glastonbury Southern Gage has specialized in cylindrical taper gages for many years with specially modified equipment for grinding and more importantly measuring a taper. The ANSI standard on Machine Tapers is confusing to the average user. These standards are written for the machine tool builder and tool holder manufacturer not the gage manufacturer or the customer trying to measure machine tapers. If you order a taper ring and plug gage to the ANSI standard they will not blue to each other. The machine taper ID is made with a decreasing taper, while the tool holder’s OD is made with an in- creasing taper. The proper ordering procedure is to order a PLUG to the standard and a “check ring” to check the plug for wear, and visa versa for the RING to the plug.
