Gage Enables Accurate In-Process Measurement
The Heidenhain-Specto ST 3087 RC gage has a special housing for in-process measurements.
The Heidenhain-Specto ST 3087 RC gage has a special housing for in-process measurements. In the plunger’s rest position, it houses the plunger, the rubber bellows surrounding it and a splash guard cap to close the exit opening for the plunger in the housing. For measurement, which is normally made when the cooling lubricant is switched off, only the plunger and its bellows extend out of the housing, driven by compressed air.
Measurement is often isolated to quality islands or labs rather than fully integrated into the ongoing process. This system increases productivity and efficiency by enabling the integration of this measuring device directly into a contaminated production process.
The optical scanning provides highly accurate position values with a maximum error of ±1 µm over a 30-mm measuring range. Because of its 30-mm stroke and high accuracy over the entire measuring range, it measures diverse components from the same fixture. Optical scanning with the ball guide enables consistent repeatability when scanning oblique surfaces. The cycle time for measurements is said to be under 1.5 sec.
Simple "roughness" measurements remain useful in the increasingly stringent world of surface finish specifications. Here's a look at why surface measurement is important and how to use sophisticated portable gages to perform inspections on the shop floor.
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.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
