What is PG optical grinding?
Maybe everyone may feel strange when they hear the word PG optical grinding. They don't even know what PG optical grinding is. They don't even know that it is a kind of processing method commonly used in precision mechanical parts or precision mold parts. Let the silver picture Xiaobian explain to you what is PG optical grinding, what kind of processing is it.
PG optical grinding is a popular precision machining method, which is mainly used to process key parts in precision equipment such as stamping dies. It is suitable for molding and grinding of high hardness materials. Reference parameters:
High hardness workpiece: workpiece hardness (HRA) ~~88-96
Surface roughness: RZ~~0.2um/F1.0mm/min
Workpiece thermal displacement: <=2um Machining accuracy: The tolerance can be stabilized within 0.001mm.
Processing method: It needs to be processed by the plotter. The plotter draws the graphic to be processed on the film, and the film is attached to the projection screen and corrected. The processor will perform the forming process according to the molding on the film.
