We may have different understandings of precision hardware processing. How to understand precision hardware processing? How to define precision hardware processing? What is the definition of precision hardware processing?
Smile Precision believes that the definition of precision hardware processing is the process of completing the final processing of various main surfaces according to steps and processes, including workpiece parallelism, surface finish, surface verticality, surface hardness, etc., to ensure that the machining accuracy and surface quality of the parts meet the requirements specified in the drawing.
Parallelism requirements for precision hardware processing
The so-called parallelism requirement refers to the tolerance requirement around the workpiece. For example, for a rectangular workpiece, the thickness of the four corners of the workpiece is required to reach a certain tolerance range. If the thickness of the four sides cannot meet the tolerance requirements, then the parallelism requirements cannot be met. This requires readjusting the workpiece, as the problem may arise in the grinding machine suction cup, which may wear out due to excessive use, resulting in parallelism errors; It may also be that the grinding wheel has not been properly repaired, or there are cracks or gaps in the grinding wheel, which requires re grinding the grinding wheel; It is also possible that the suction cup has not been cleaned thoroughly, so it is necessary to clean the suction cup again and carefully; It is also possible that the workpiece has not been properly trimmed, resulting in burrs.
Perpendicularity requirements for precision hardware processing
The so-called perpendicularity requirement refers to the requirement that the side and ground of the workpiece meet the tolerance requirements. The best understanding is the legitimate entity, which is divided into XYZ three sides from the number axis. Generally, it is required that XZ and YZ meet the tolerance requirements. The occurrence of errors is generally consistent with the requirements for parallelism. Generally, it can be processed according to the requirements of parallelism.
Other requirements for precision hardware processing
For example, smoothness. It is required to achieve, such as mirror effect.
