Title: Polishing Process Of China Mechanical Parts
Tags: China Mechanical Parts
Blog Entry: China Mechanical Parts surface treatment generally pursues three objectives: Change of the surface roughness You have two options here. You either polish the surface to make it smoother, or you roughen it to improve adhesion. 2. Cleaning and degreasing of surfaces This is to ensure that the surface is free from any foreign matter such as rust or scale, and, of course, for removing old coatings. 3. Densification of surfaces This method aims at creating more uniform structures or at achieving dimensional accuracy. Polishing - Finishing Processes Polishing is a smoothing finishing technique that is suitable for various materials. The smoothing effect is generally achieved by two mechanisms: On the one side, roughness peaks in the surface structure are plastically and partly plastically smoothed (also called burnishing). On the other hand, and depending on the kind of polish used, a minimum to very small amount of material is removed (buffing) And surface imperfections like pits or scratches are filled in. The smooth surface thus obtained often has a glossy appearance. Tools with rotary buffing wheels made of cloth, felt or leather are mainly used for polishing metal materials. The actual polish compound is either applied as a suspension or paste onto the wheels which are also referred to as a polish carrier. The polish compound consists of different greases, oils and the actual abrasive. This may be alumina, aluminum oxide, chromium trioxide or Similar. Grinding Grinding is an abrasive machining process in which material is removed by abrasive particles while the work piece and the grinding wheel are in relative motion to each other. It is a path-based cutting process to machine surfaces or to cut materials by using bonded abrasives. This process is classified into the main category "cutting". It also belongs to the group of cutting processes with a geometrically undefined cutting edge.
