Surface Finish Analysis

Surface Finish Analysis Banner

 

Q-PLUS offers advanced surface finish analysis and surface mapping and metrology capabilities 
including graphical depictions, numerous sensor configurations, many algorithm and post-processing options, and even the raw surface finish data. All surface finish measurements comply with ASME-B46.1.

How we acquire surface finish data:

  • Skidded 2D Contact Profilometry
    This type of measurement process involves a gage with a sensitive stylus contained within a probe attached to the metal rest pad, or skid that rests on the object being analyzed. The stylus and skid move together to measure the average roughness of the part's surface.

  • Skidless 2D & 3D Contact Profilometry
    Skidless surface finish analysis is a contact measurement method of acquiring finish data with a stylus. Because the skidless gages use an internal precision reference surface, these gages can measure form and waviness in addition to roughness on a micro-inch level.

  • Noncontact 2D & 3D Optical Profilometry
    This profilometry is a non-contact method which accommodates many sample geometries via chromatic confocal technology which uses white light to collect measurement data. However, whereas interferometry uses the superposition of waves after they are reflected off the object, chromatic confocal sensors measure the wavelength as it hits the surface of the object.

  • Nano Scanning

    Nano Scanning involves 3D scanning at the sub-micron level and is accomplished with a chromatic confocal sensor. This type of scanning can be used to measure or digitize very small geometry and can also acquire surface roughness data.

Q-PLUS Labs Introduces the GapGun Pro for Revolutionary Speed in Portable Measurement

June 2017: Q-PLUS Labs adds the GapGun Pro to its expansive measurement arsenal. A versatile, hand-held, in-process quality inspection solution, the GapGun Pro rapidly captures measurement data for gap and flush, radius, edge break, burr, countersink, scratch, weld, seal, angle and more. Along with its ability to measure across a wide range of applications, the GapGun Pro also accommodates measurements from carbon fiber to high gloss black paint and chromes. It can also distinguish between different colored parts due to its VChange sensors’ Hi-Range measurement capability which dynamically adjusts the system’s output to allow measurement on multiple surface conditions. Its intuitive user interface enables the operator to always have a read on the results of the GapGun’s full color screen, even in difficult to reach measurement scenarios, allowing the operator to cut down on the amount of time it takes to collect data and increasing overall measurement throughput.
