In the process of production, its large-scale machining is very important. To a certain extent, everyone needs to carry out according to its relevant standards and requirements, in this way, the machining accuracy can be ensured to a certain extent, so that accessories with suitable sizes and shapes can be produced, and our work can be carried out more continuously and normally, will not cause too much impact and loss. To a certain extent, the processing technology of large-scale mechanical processing is to use its corresponding processing methods to process and manufacture mechanical parts, in this way, its shape, nature and size can conform to its corresponding standards to a certain extent, to a certain extent, it mainly includes rough machining, finishing, assembly, inspection and packaging, etc. As long as everyone ensures the accuracy of each processing process, the finished product can be more standardized and reasonable, ensure that it meets relevant standards. Large-scale machining can effectively remove the oxide scale on the parts to a certain extent, and the appearance of the parts processed at the same time should not have scratches, scratches and other defects to a certain extent. When the assembly is too heavy, it should ensure that its shape, length, size and temperature conform to relevant standards, and at the same time ensure the sealing performance of the whole system so as not to affect the assembly hydraulic system. In the process of assembly of large-scale mechanical processing, to a certain extent, it is best to effectively avoid scratches, corrosion, corrosion and other conditions of parts, which will affect the large-scale mechanical processing, the performance of the product is affected and damaged, and our work cannot continue normally. Large-scale machining is mainly composed of many surfaces in the manufacturing process, and the surfaces of its parts are relatively related. To a certain extent, a benchmark must be determined, in operation, its reference is the point, line and surface on which the position of other points, lines and surfaces is determined. According to the different functions of the benchmark, the benchmark can be divided into two types: Design Benchmark and process benchmark. Design datum: the datum used to determine the positions of other points, lines and planes on the part drawing is called design datum. Process benchmark: the benchmark used in the processing and assembly of parts is called process benchmark. Process benchmarks are divided into assembly benchmarks, measurement benchmarks and positioning benchmarks according to different uses.
