In modern industrial manufacturing and quality inspection, the accurate measurement of surface roughness is crucial. The emergence of POMEAS spectral confocal sensors has brought a new solution for surface roughness measurement, which has demonstrated extraordinary application value.

Advantages of non-contact measurement

Traditional methods of surface roughness measurement often have limitations, such as the possibility of damage to the surface of the object being measured by contact measurement, or the introduction of errors in the measurement of certain delicate or soft materials. POMEAS spectral confocal sensors avoid these problems by using a non-contact measurement method. This non-contact feature makes the measurement process gentler and does not alter the surface condition of the object under test. This ensures that the accuracy of the measurement results is not disturbed by external factors, whether the measurement is on high-precision mechanical parts or fragile materials such as optical lenses. Furthermore, since direct contact with the object surface is not required, the service life of the sensor is extended, reducing problems such as loss of accuracy due to frequent contact wear.

Measurement accuracy at the micron level

POMEAS spectral confocal sensors are capable of measuring surface roughness with micron-level accuracy, a high-precision feature that makes them stand out in a wide range of application scenarios. At the microscopic level, micron-level accuracy means that it is able to capture extremely subtle variations in surface undulations. For some demanding industrial manufacturing areas, such as aerospace components and high-end precision instrument manufacturing, even small differences in surface roughness can affect the performance of the entire product. The sensor can accurately measure these tiny roughness values, providing reliable data support for quality control. For example, in the manufacturing process of aero-engine blades, the roughness of the blade surface affects the flow characteristics of the airflow, which in turn affects the efficiency and stability of the engine. POMEAS spectral confocal sensors are able to accurately measure the blade surface roughness to ensure that it is within the design requirements, guaranteeing high engine performance.

Application in the judgement of sealing and surface quality of parts

In industrial production, the sealing and surface quality of parts are key indicators for assessing product performance. POMEAS spectral confocal sensors play an important role in these aspects. For parts that need to be sealed, such as cylinder blocks in automotive engines and seals in hydraulic systems, the surface roughness is directly related to the sealing effect. If the surface is too rough, it may lead to poor sealing and cause problems such as leakage.

By accurately measuring the roughness of the sealing surface of a part, the spectral confocal sensor can detect potential sealing problems in time and help manufacturers make adjustments and improvements in the production process. In terms of surface quality judgement, it can comprehensively assess the flatness, texture and other characteristics of the part surface. Through the analysis of a large amount of measurement data, it can determine whether there are scratches, pits and other defects on the surface of the parts, thus achieving effective monitoring of product quality. For example, in the production line of automotive parts, the sensor is used to measure the surface roughness of key parts such as brake discs and pistons, so that unqualified products can be quickly screened out and the overall quality and safety of the products can be improved.
