Frequently Asked Question

1. Which instrument is used to measure the surface roughness?

A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material. A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometers or microns (µm).

2. What is a good surface roughness?

A standard #4 finish could be about 0.8 (32) Ra, while a #4 Dairy or Sanitary finish have an roughness average between 0.3 (12) Ra and 0.4 (16) Ra. Two other finishes; #7 and #8 are buffed. The surface of #8 is very nearly flawless. The Ra on a #8 finish would be 0.025 (1) Ra.

3. How do you choose surface roughness?

You can calculate surface roughness by measuring the average surface peaks and valleys across that surface. The measurement is often seen as 'Ra,' which means 'Roughness Average. ' While Ra is a very useful measurement parameter.

4. What is a surface roughness gauge?

Surface roughness testers, also known as roughness gauges, are portable and have a stylus with a small, smooth contact point for tracing the surface of a workpiece to measure minute irregularities. The surface measurements are displayed on the LCD screen.
