How do you use the surface roughness comparator?

How to use a Surface Roughness Comparator

1. Place the roughness scale next to the work piece.
2. Slide the various scales next to each other so that the comparator scale area is adjacent to the surface you are measuring.
3. Compare by drawing your fingernail across each surface at right angles to the tool marks.

What is surface roughness gages?

The surface profile roughness gauge is a simple instrument for ultrafast measuring of the point peak-to-valley height of a surface. The shape of the base makes this instrument ideal to measure the height of welds.

What is a surface finish comparator?

Surface finish comparators are tools that quantify the surface quality of a material that has undergone machining and surface finishing processes. Surface finish comparators are available for many manufacturing processes, including: Milling. Turning. Casting.

What is a profilometer used for?

Profilometry is a technique used to extract topographical data from a surface. This can be a single point, a line scan or even a full three dimensional scan. The purpose of profilometry is to get surface morphology, step heights and surface roughness.

What is surface profile gauge?

A surface profile gauge is a type of profile gauge that measures the surface roughness of an object, usually to facilitate substrate preparation and the application of a protective coating. By looking at the gauge, the technician can determine the height or depth of surface irregularities.

How do you measure the roughness of a surface?

Roughness can be measured by manual comparison against a “surface roughness comparator” (a sample of known surface roughness), but more generally a surface profile measurement is made with a profilometer.

What is a roughness comparison specimen?

These are often unsuitable for workshop use, where roughness of machined surfaces can usually be assessed conveniently and with sufficient reliability by means of visual and tactile (fingernail) comparison of a workpiece with a standard set of surfaces machined in the same way. Such sets of surfaces are called roughness comparison specimens.

What is the roughness of the microsurf range?

Details of our Microsurf range. This comparator scale has 12 specimens of spark- eroded (EDM) surfaces, with roughness values corresponding to nos. 12 – 45 inclusive as specified in the internationally-used guideline document VDI 3400. A label on the back states the Ra roughness value for each patch.

Where are Rubert & Co Ltd located?

Welcome to Rubert & Co Ltd. We are world leaders in the design and manufacture of surface texture specimens and calibration standards and are UKAS accredited. Our factory and head office is located in beautiful surroundings in Cheadle near Manchester, in the UK.

What is the difference between the 015 and the 016 comparators?

No. 015 is the Superintendent’s version for office use. No. 016 is the Diver’s version for underwater use. These two comparators are specially designed to check the roughness of steel surfaces which have been blast cleaned to cleanliness grades SA 2.5 and SA 3 in preparation for painting. They conform to ISO 8503.
