Portable Surface Roughness Tester – Sufttest SJ-410 Series

In metrology, we work with surfaces every day. Whether measuring an object, putting a part together, troubleshooting an issue, or more, the surface of materials is central to what we are doing. Surface roughness in particular is more than just a tactile observation. Surface roughness is important to know because of how it impacts the ability of surfaces to hold together. In general, knowing how rough a surface is can help us determine whether it is the best surface for a particular purpose. This brings us to the roughness tester. A roughness tester is a tool designed to efficiently and accurately determine a measurement of roughness or texture. Portable roughness testers go even further by taking roughness measurement on-the-go. We would like to highlight a few of our favorite new portable surface roughness testers. Today, we are talking about the Sufttest SJ-410 Series.

What the Sufttest SJ-410 Series Can Do

The Mitutoyo Sufttest SJ-410 Series portable surface roughness testers are top of the line tools that will improve your workshop. The roughness tester determines a measurement of depth (Rz) and a measurement of mean value roughness (Ra). Both depth and mean are reported in micrometers or microns (µm). The Sufttest SJ-410 Series is one of the finest measurement tools available, upgrading the process of measuring surface roughness in ease, safety, quality, and efficiency.

 

Unique Benefits of the Sufttest SJ-410 Series

Portable surface roughness testers from the Mitutoyo Sufttest SJ-410 Series were created with the user in mind. The unique benefits of the Sufttest SJ-410 Series come from the user experience.

Utility and Safety

First and foremost, the Sufttest SJ-410 Series portable surface roughness testers have improved the ease and safety of taking roughness measurements. When working with these portable roughness testers, anyone can perform accurate and efficient roughness measurements. With the new auto set unit, you can perform measurements with the single push of a button while the machine controls the detector’s decent. By removing this task from the operator’s responsibility, the Sufttest SJ-410 Series eliminates concern for human error or accidental damage. The auto-set unit on these portable roughness testers automatically engages in the process of contact, measurement, and retraction, with an on-off option of both the stylus retraction and the detector auto-return. Additionally, when completing one measurement you can now conduct two different evaluation analyses at the same time. Efficiency of the Sufttest SJ-410 Series is excellent since you can calculate parameters and analyze filtered profiles with only one collection of data. The available 3-axis adjustable table also allows for quick measurement of roughness on cylindrical surfaces by correcting for pitch and swivel angle. A built-in guide on the screen will walk you through leveling the table to align with the detector reference plane. Finally, the Sufttest SJ-410 Series portable roughness testers come with an easy to use height and tilt adjustment unit. Highly accurate alignment and skidless measurements are possible because of the powerful leveling support.

Quality Control

Again, with the user in mind Mitutoyo made the Sufttest SJ-410 Series to offer a higher level of quality control for any operator. With a built in wireless communication system and advanced analysis functionality, any user can complete complex high-level data collection as well as analysis no matter your specific background. Data input and analyses have never been simpler. With the U-Wave wireless input tool, you can remotely load calculations into a spreadsheet on an external computer. Additionally, with the USB one-touch input tool, you can also transfer data onto a computer through USB connection. With a simple touch, values are transferred from the portable surface roughness tester to your logging spreadsheet, whether wirelessly or using the USB connection. With the included free software, the simplified communication program, users of the Sufttest SJ-410 Series can enable measurement condition set up and starting, as well as create inspection record tables on your computer. The Formtracepack-AP assists in further processing of data resulting in higher accuracy measurements with the selectable drive unit and extended measurement of narrow features. The required run-up distance prior to taking a roughness measurement on the Sufttest SJ-410 Series is set to 0.5mm, but can be easily adjusted to 0.15mm through the narrow-part function. You can even use this feature to take measurements of piston-ring grooves and O-ring grooves. Finally, parabollical, ellipsoidal, spherical, and cylindrical surfaces can all be evaluated be removing the radius with a filter, resulting in the R-surface data being processed as though it is collected from a flat surface. Advanced analysis, accurate measurements, and creation of inspection record tables have never been easier than they are with the Sufttest SJ-410 Series portable roughness testers.

Space Saving

The Sufttest SJ-410 Series portable roughness testers are not only capable of excellent roughness testing, but also of contour and fine contour measurement, making these machines space savers by doing the work of two tools. With a simple contour analysis function, the Sufttest SJ-410 Series uses point group data to complete step, step height, area, and coordinate difference measurements. In fact, it goes a step further assessing minute forms that the standard contour measurement machine misses. Users can complete either skidless or skidded measurement depending on individual roughness measurement needs. If you need to collect a measurement of surface features relative to the drive unit reference surface, complete a skidless measurement with the Sufttest SJ-410 Series; if you need to collect a measurement of surface features relative to a skid following close behind the stylus, complete a skidded measurement with the Sufttest SJ-410 Series. Every Sufttest SJ-410 Series portable roughness tester comes equipped with externally controllable interfaces (USB, RS-232C, SPC output, and foot switch I/F), optional memory card for extra data storage and easy printouts after on-site measurement, as well as a high-speed thermal printer for fast and clear standard printouts in addition to prints on a BAC or ADC curve. Finally, the Sufttest SJ-410 Series portable roughness testers all come with a convenient carrying case that simplifies the travel process and makes storing the device simple and compact.

Conclusion

A surface high in roughness will tend to wear down faster than a surface low in roughness. In other words, smoother surfaces result in less wearing. Higher roughness can be a helpful factor when it comes adhesion properties. Overall, knowing the roughness of a surface is vital to completing proper measurement and assembly. The Sufttest SJ-410 Series of portable surface roughness testers can help you to measure roughness quickly and properly, without the challenges presented by normal roughness testing tools.

GLOSSARY TERMS

Interferometer

An interferometer is a tools that uses merged sources of light to develop an interference pattern. Once the pattern is recognized by the interferometer, it can be measured and analyzed. Sometimes used by surface roughness testers to determine surface measurements of an entire area, the interferometers can be used to make very small measurements, as small as 1/10,000th the width of a proton.

Roughness Tester

A roughness tester is a metrological device design to measure surface roughness. By collecting data from a mechanical stylus that moves along a surface, a roughness tester provides data concerning depth and mean value roughness. Typically, measurements from a roughness tester are reported as micrometers or microns. Depending on the design, a roughness tester may provide areal roughness data using lasers, optics, or interferometers.

Portable Surface Roughness Tester

A portable surface roughness tester functions identically to a standard surface roughness tester, but by design is meant to be used on the go. Typically, smaller in size and lighter in weight, portable surface roughness testers provide data about surface roughness and come with features that make them durable with high usage and across measurement environments. Data collected using a portable surface roughness tester will often be stored on the device itself and then later transferred via USB or wirelessly to a computer.
