The basic introduction and technical requirements of large mechanical processing

by:NJPE     2020-06-26
In the process of production, it is very important to its large mechanical processing, to a certain extent, we need according to the relevant standards and requirements for, so that you can to a certain extent to ensure the precision machining accuracy, so as to produce the size and shape a suitable accessories, make our work more continuous normal, won't cause too big effect and damage. Processing technology of large mechanical processing to a certain extent, is the use of its corresponding processing method processing machinery spare parts for production, so that you can to a certain extent, make its shape, nature, size is accord with standard of its corresponding to a certain extent, to a certain extent, mainly including the rough precision machining, finish precision machining, assembly, inspection and packaging process, as long as you make sure the accuracy of each process and will be able to make product more standardized, reasonable, ensure that it conforms to the relevant standards. Large mechanical processing to a certain extent, can effectively remove the oxide coating on the parts, to some extent at the same time, the appearance of the processed parts should not appear defects such as scratches and bruises. In the assembly of the heavy, should ensure that its shape, length, size, temperature, comply with relevant standards, at the same time guarantee the sealing of the whole system, so as not to affect the assembly of the hydraulic system. Large mechanical processing in the process of assembly, to a certain extent, best can effectively avoid parts to the scratch, rust, corrosion, etc. , affect the large-scale machinery processing, makes the impact and damage from the performance of the product and let our work cannot continue to normal. Large mechanical processing in the production process is mainly composed of a number of surface, its parts surface is relative relationship, in a certain extent, must determine a benchmark, when operating with the benchmark is used to determine other parts of dot, line, the position is based on dot, line, face. According to the different function of the benchmark, the benchmark can be divided into two categories, design datum and technology datum. Design basis: on the part drawing to determine other point, line, face the benchmark, known as design basis. Process benchmarking: parts used in the process of processing and assembling of benchmark, known as benchmark process. Process benchmarking is divided into different according to the use assembly datum, measurement datum and position datum.
