Introduction to non-standard parts processing knowledge

Non-standard parts processing refers to mechanical equipment that is not manufactured according to uniform standards in terms of type, specifications, performance, dimensions, drawings, tolerances and fits, technical document numbers and codes, technical languages, measurement units, and materials and process equipment used.

Non-standard parts are non-standard equipment, not equipment manufactured in accordance with the unified industry standards and specifications promulgated by the country, but equipment designed and manufactured by oneself according to their own use needs. And the appearance or performance of the equipment is not in the national equipment catalog.

In order to meet the needs of large-scale industrial production, the mechanical equipment that has been produced and proved to have good performance is finalized and serialized, called standard products. According to user requirements, on the basis of standard products, products produced, modified or customized are called non-standard products.

The fields where there are more occasions for non-standard products are mainly the chemical and petrochemical industries. Because there are so many products in this industry, the craftsmanship is very different, so there are many non-standard products.
