The so-called non-standard parts processing, in essence, it refers to the process of forming these parts are not produced and made in accordance with the relevant regulations and requirements. Parts of this nature are used in both the metal and non-metal industries. Depending on what is actually required, many models are not produced with the specifications intact as designed. After all, every device has its error values. The machining of non-standard parts has a great significance and role for the equipment industry.
Non-standard parts processing refers to the type, specification, performance, size, drawing, tolerance and fit, technical file number and code, technical language, unit of measurement and the materials and process equipment used, etc., not manufactured according to a unified standard of mechanical equipment.
Non-standard parts are non-standard equipment, not in accordance with the uniform industry standards and specifications promulgated by the state manufacturing equipment, but according to their own use needs, self-designed and manufactured equipment. And the appearance or performance of the equipment is not in the national equipment catalog. In order to meet the needs of large industrial production, the machinery and equipment that have been produced and proven to perform well in use are stereotyped and serialized, called standard products. And according to the user requirements, on the basis of the standard products, production, transformation or customized products are called non-standard products. The field that mentions more occasions of non-standard products is mainly the chemical and petrochemical industry. Because there are many products in this industry and the process is very different, so there are more non-standard products.
