Product Description

We are counted among the reputed business entities, engaged in offering Surface Roughness Test Service. It is performed to compare the actual condition of a manufactured part or component to the nominal condition as defined by engineering drawings and blueprints. We provide on-site testing, utilizing innovative technologies including laser tracking, dynamic retro-reflective tracking or portable coordinate measuring. We offer Surface Roughness Test Service at reasonable rates. 


  • Utilize the proper equipment for surface analysis
  • Measure the texture of a manufactured surface
  • Timely execution

Further Details:

The quality of machined surface is characterized by the accuracy of its manufacture with respect to the dimensions specified by the designer. Every machining operation leaves characteristic evidence on the machined surface. This evidence in the form of finely spaced micro irregularities left by the cutting tool. Each type of cutting tool leaves its own individual pattern which therefore can be identified. Alternatively surface finishes imparted by shot blasting, shot peening, Electro Discharge EDT, or other plating operations impart a specific surface finish.

This pattern is known as surface finish or surface roughness and can be measured by a surface profilometer machine which quantifies the surface roughness i.e. positive deviation from a datum plane (peak) or negative deviation from a datum plane (valley) as well as peaks per inch. The roughness is expressed in micro-inches or micro-meters and expressed as AR (arithmetic average) or RMS (Root Mean Square) values.


Narang Metallurgical & Spectro Services offer Surface Roughness Measurement parts at our facility which can provide a valuable evaluation for warranty and product issues, such as:                                        

  • Wear verification
  • Noise or mating part irregularities
  • Seal Leaks

Narang Metallurgical proficiency with surface measurement allows us to accurately identify the problem at hand, apply standards, and utilize the proper equipment for surface analysis.  

Narang Metallurgical can help you make sense of your surface roughness measurement requirements, provide the proper means of surface analysis, and establish the correct parameters necessary to help you qualify sensitive details of your part’s performance.
