Surface Roughness Testing
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 is 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 profilo-meter 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.
This machine helps Pharmalab increase the quality in its finished product to match the best international practices and cGMP guidelines.
