How to define precision hardware processing in the field of manufacturing?

　　In the field of industrial manufacturing,different practitioners or researchers may have different understandings of precision hardware processing.So,how to accurately understand precision hardware processing?How to define it accurately?What is the definition of precision hardware processing?

 

　　Wuxi Caiyuan Machinery believes that precision hardware processing refers to the process of completing the final processing of the main surfaces according to the established steps and processes,so that the processing accuracy and surface quality of the parts meet the requirements of the drawings.This process involves many key indicators of the workpiece,such as parallelism,surface finish,surface verticality,surface hardness and so on.

 

　　Parallelism requirements for precision hardware processing

 

　　The parallelism requirement is mainly related to the tolerance control of the workpiece periphery.Take a rectangular workpiece as an example,the thickness of its four corners should be within a specific tolerance range.If the thickness of the four sides of the workpiece is measured and the result exceeds the tolerance requirement,it indicates that the parallelism requirement is not met.At this time,it is necessary to check the processing process.The possible reasons include:the grinding machine sucker is worn due to long-term use,resulting in deviation when the workpiece is adsorbed,thus affecting the parallelism;the grinding wheel is not properly trimmed,or cracks,gaps and other conditions occur,resulting in errors in the grinding process,at this time,the grinding wheel needs to be refinished;the sucker is not cleaned up,and the residual impurities affect the placement flatness of the workpiece,so the sucker needs to be carefully cleaned again;The workpiece itself is not finished well in the early treatment,and there are burrs,which affect the measurement and processing accuracy.

 

　　Verticality requirements for precision hardware processing

 

　　The perpendicularity requirement means that the side and bottom surfaces of the workpiece must meet the specified tolerance requirements.Taking a cube workpiece as an example,the XZ plane and the YZ plane are generally required to meet the tolerance requirements from the perspective of the number axis dimension.When a perpendicularity error occurs,the cause is roughly similar to the cause of a parallelism error.When dealing with the problem of perpendicularity error,we can usually refer to the troubleshooting and solution of parallelism requirements.

 

　　Other requirements for precision hardware processing

 

　　In addition to parallelism and perpendicularity,surface finish is also one of the important indicators.In some precision hardware processing,the surface of the workpiece is required to meet specific finish standards such as mirror effect,in order to meet the needs of high-precision use and appearance requirements.
