How to choose deburring technology and its detection method

1.Proposal of the problem When designing a part of the hydraulic system of the roadheader, I wrote the words "Remove the burrs at the intersection of the holes" in the technical requirements, but some people have difficulty in processing, inconvenient to inspect, and increase processing. The cost is based on the question. Workers often neglect the deburring process, and some designers do not pay much attention to it. In the drawings, they often miss out on "deburring" or "edge blunt". In fact, deburring is a very important process. In the hydraulic system, once the burr on the part falls off and enters the component, it will jam the sliding valve, damage the surface of the part, cut the hose or block the liquid outlet, etc., affecting the performance of the main engine and even stopping the machine. If the burr falls on the positioning base, it will affect the processing accuracy; the burr is also easy to scratch the worker, affecting the assembly quality and the life of the part.

The accuracy of the steel tape will directly affect the measurement accuracy, so the quality of the steel tape must be verified during use. At present, most metrology institutes are still using manual operation to complete the inspection of steel tapes. Use a microscope to compare the error of the measured steel tape with the standard steel tape on the steel tape long inspection platform. This method is automated, low in digitization, and labor-intensive. Big.
