Webinar: Shop Floor Surface Finish Measurement with 3D Optical Gauges
2025-04-02 12:00 - 13:00 (America/New_York) | OH
Join us on Wednesday, April 2, 2025, from 12:00 p.m. to 1:00 p.m. EST, to learn how you can take advantage of our rugged, portable roughness system to provide 3D surface finish measurements with nanometer resolution right on the shop floor.
REGISTER >
Until now, companies have typically relied on 2D stylus-based systems or expensive, non-portable optical profilers that can be time consuming and extremely sensitive to environmental factors, typically confining them to extremely quiet vibration-isolated lab environments. Optical profilers have the added burden of being stationary and therefore limited in sample sizes and geometries that can be measured.
This exclusive webinar demonstrates how to take advantage of our rugged, portable roughness system to provide 3D surface finish measurements with nanometer resolution right on the shop floor.
The 4Di InSpec® SR employs patented technology for rapid surface measurements unaffected by vibration.
You’ll learn how to beat the most difficult metrology challenges:

3D roughness of hard-to-reach areas and large samples
3D roughness in any orientation – right on the shop floor
Automating 3D roughness measurements
Integrating 3D roughness systems into process machining systems

See firsthand how user-friendly the 4Di InSpec® SR is with live demonstrations measuring various industrial samples manually.
With a roughness accuracy of better than 0.5% and its small, portable form factor, the 4Di InSpec® SR can measure in any orientation on applications including:

Aviation & aerospace parts such as engine rotors, turbine blades, shafts, and gears
Automotive parts including engine cylinders, cranks, bores, gears, brake pads, and EV batteries
Medical implants
Precision machined surfaces
Precision bearings
Shot peen surfaces
In-situ precision machining (grinding, polishing, lapping)
Additive manufacturing
Semiconductor bare and processed wafers

Who should attend this webinar? If you’re in these fields:

Aerospace, aviation, MRO, medical device industries
Parts manufacturing
Machining or 3D printing
Inspection and qualification
Engine / component repair
