Air Gage Readout Accurately Measures Tapered Diameters
IMTS 2018: Western Gage’s Micro IIi air gage readout provides fast and accurate measurements of tapered internal and external diameters.
Western Gage’s Micro IIi air gage readout is said to provide fast and accurate measurements of tapered internal and external diameters. The air gage instrument features a built-in microprocessor, digital and analog displays, RS-232 serial data output, and auto calibration with master gages. Taper angles and datum diameters are displayed with a resolutions as fine as 5 micro-inches or 0.1 micron. Applications include measurement of machine tool spindle tapers, toolholders and medical implant tapers.
Just because dial indicators have been around since the early 1900s, don't expect them to fade away with the last century. This tool's long-term popularity is well earned.
Virtually every machine tool builder lists, as part of a machine's specification, accuracy and repeatability figures. What's generally not given is the method used to arrive at the figures. Though these methods are defined in linear positioning standards, not all builders use the same standards.
Few manufacturing companies rely on ballbar testing to maintain machine tool accuracy as thoroughly as Silfex. Now, advanced training and a move to a Renishaw QC20-W wireless system have enabled the company to take the benefits of ballbar testing to a higher level.
