TYPE:
The specimens are electroformed replicas of original cast surfaces.

MATERIAL:
This MICROFINISH COMPARATOR Surface Roughness Scale is made of nickel. It will not corrode.

APPEARANCE:
Each specimen has the surface roughness characteristics of a cast metallic material.

It is recognized that the RMS roughness designation which specifies the required finish of a part in micro-inch (millionths of an inch) and is the average amount by which the finish may vary from the nominal surfaces is not a satisfactory method of specifying cast finishes.

The RMS designation reflects the tool marks which are more or less constant across a surface while the casting reflects one or more of the following:

A. The grain size of the cooling metal surface.

B. The sand grain size of the mold.

C. The grain size of the ceramic wash on the steel mold.

D. The grain size of the ceramic investment mold.

Surface roughness, for purposes of this forum, is the result of some machining process and its effect on the material surface in question. 

Skid type surface roughness testers are common instruments used on the shop floor. A diamond stylus is traversed across the specimen and a piezoelectric pickup records all vertical movement. Peaks and valleys are recorded and converted into a known value of a given parameter. 

Parameters differ in how they approach looking at peaks and valleys. The most popular parameter is “Ra”. Ra is commonly defined as the arithmetic average roughness. While the Ra parameter is easy and efficient, there are other parameters that can be more specific and useful depending on the application requirements. It is the parameters that enable us to define surface roughness.

Today, for the purpose of checking Ra values, the use of portable, hand held, surface roughness testers are not only economical, but are digital and easy to use. These surface roughness testers are a given necessity for any shop floor that receives work with Ra requirements.

 Features

·         Pocket-size & economical price

·         Large measuring range suitable for most materials

·         Measures flat, outer cylinder and sloping surface

·         Both Ra and Rz parameters in one instrument

·         Features external calibration at keyboard

·         Standard conform to ISO and DIN

·         Rechargeable batteries, work while charging

·         TR110 is equipped with Li-ion battery and backlight

                                                            MEANING of DIFFERENT PARAMETERS

 

·         Ra : Arithmatic Mean Deviation of the Profile is Arithmatic Mean Value of the deviation of the profile within the sampling Length

·         Rz: The Maximum Height of irregularities is the distance between maximum depth of the profile peaks and maximum depth of profile valley with in the sampling range .

·         Rq: RooT mean Square Deviation of profile of devaiation

·         Rt; Total Peak to Valley Height

·         Rt is the sum of height of the highest peak and the depth of the deepest valley over the evaluation length
