WESTport Gage manufactures a complete line of standard taper ring and taper plug gages;Morse, Jarno, Brown & Sharpe, Jacobs, National Machine and any other special taper gage made to your blueprint specifications. WESTport also manufactures tapered arbors to your print or our engineering team will gladly assist in developing drawings for your application based on common gaging practices.
The ANSI standard on Machine Tapers can be a bit confusing to the average user. If you order a taper ring and plug gage to the ANSI standard they will not true to each other. The machine taper ID is made with a decreasing taper, while the tool holder’s OD is made with an increasing taper. The proper ordering procedure is to order a PLUG to the standard and a “check ring” to check the plug for wear, and vise versa the RING to the plug. All Standard Tapers manufactured to ASME/ANSI B5.10 class Z unless otherwise specified. To learn more about Cylindrical Taper Gages CLICK HERE.
