The basic unit and process of large-scale machining

Large-scale mechanical processing is very important for the construction of this city, so their workload is very large, and the quantity that needs to be processed is very large. If you try to choose recyclable raw materials when processing, use energy-saving Environmentally friendly and low-consumption processing machines will produce less pollution. After a long time, when the machine needs to be updated, it can also be recycled to the relevant department for processing and re-production. Such a production concept is required for mechanical processing. Now Many companies need to buy a lot of machinery for their own business. They will also consider energy-saving and environmentally friendly machinery. Of course, they also value the cost-effectiveness of the product. The quality is required. The price is discounted compared to other products. For such products, they are There is no resistance.

Generally, large-scale mechanical processing has strict requirements for employees. The tasks must be completed within the specified time. In the production process, those processes that are directly related to the transformation of raw materials into products are called technological processes. It includes blank manufacturing, parts processing, heat treatment, quality inspection and machine assembly. The manufacturing of tools, fixtures, and machine tool adjustment and maintenance required for the normal process of the process are auxiliary processes. In the process, the processing method of large-scale mechanical parts in Dalian gradually changes the shape, size, relative position and performance of the blanks in a certain order, until the part of the process that becomes a qualified part is called the mechanical processing process.

Technical personnel of large-scale mechanical processing determine the technological process to be adopted according to the quantity of products, equipment conditions, and the quality of the workers, and write the relevant content into technological documents, which are called technological regulations. In order to facilitate the preparation, execution and production organization management of the process regulations, the process needs to be divided into units of different levels. They are process, installation, station, work step, and knife pass.

Large-scale machining of which process is the basic unit in the process. The machining process of parts consists of several processes. One process may include one or several installations, each installation may include one or several stations, each station may include one or several steps, and each work step may include one or several passes. .

The forced vibration of large-scale machining is the vibration caused by the external periodic interference force of the process system. The forced vibration in machining is no different from the forced vibration in general machinery. The frequency of the forced vibration is the same as the frequency of the interference force or a multiple of it.
