Workpiece requirements polishing is generally based on two reasons, namely functional requirements and decorative requirements. No matter what function of the workpiece, the substrate metal surface can not have defects, such as needle eyes, mechanical damage, scaling, etc., which is the premise of quality control. When the workpiece is surface polished for functional requirements, the surface provided should be able to meet the specified special application, and whether this special application can be provided as the quality control and acceptance standard of the polished workpiece.
In most cases, the workpiece polishing is based on the requirements of decoration, and the main criteria to be considered are as follows.
① The polished surface should have a pre-designed appearance.
② Each batch of workpieces should be consistent.
The above two criteria are usually qualitative requirements, which are related to the distance between the position of use and the observer, as well as to the use of the end product. For the workpiece with decorative requirements, the following specific inspection can be used as a method of quality control.
① Measure the surface roughness.
② Measure the surface reflectance or surface gloss.
③ Compare with the standard sample. There is an element of subjective judgment in this approach.
The first two methods provide objective or quantitative. The roughness test recorder can provide a complete record of the surface structure, but because the decorative effect is judged by the human feeling, the reflectivity measurement results will be more recognized in the actual detection. For very smooth surfaces, it is appropriate to measure the reflectivity of the polished surface, but the strong harsh light generated by the polished surface will hinder the measurement of the surface reflectivity, so the measurement of reflectivity is sometimes difficult to use as a quality inspection standard. Although the method of comparing with the standard sample has a lot of subjectivity, it is still a common test method for polishing quality.
