Before Precision CNC Machining Non-Standard Parts, You Must Understand What Non-Standard Parts Are?

We know that precision CNC machining parts can be divided into standard parts processing and non-standard parts processing according to the processing object. Relatively speaking, standard parts are relatively easy to process. CNC machining of non-standard parts is more difficult, and many people do not distinguish between standard parts and non-standard parts. Then, we VMT will introduce to you what non-standard parts are:

First of all, we know that non-standard parts are proposed relative to standard parts, so before we understand non-standard parts, we need to know what are standard parts? Standard parts refer to the structure, size, drawing method, marking and other aspects that have been completely standardized . And common CNC machining parts produced by professional CNC machining manufacturers, such as threaded parts, rolling bearings, etc. In a broad sense, it includes standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other precision CNC machining parts. In a narrow sense, only standardized fasteners are included. Commonly known as standard parts in my country is the abbreviation of standard fasteners. , is a narrow concept, but the existence of a broad concept cannot be ruled out. In addition, there are industry standard parts, such as automobile standard parts, mold standard parts, etc., which also belong to general standard parts.

Non-standard parts processing professionals explained that the country has not formulated strict standards and specifications, and there is no relevant parameter regulation, and other accessories are freely controlled by the enterprise. There are many varieties of non-standard parts, and there is no standard classification yet. They are roughly classified as follows:

Metal non-standard parts:

The drawings are provided by the customer, and the precision CNC machining parts manufacturers use the equipment to make the corresponding products according to the drawings, usually most of them are molds. Tolerance requirements and smoothness are specified by the customer. There is no definite paradigm. Products from casting to finishing completely need corresponding quality control, the process is complex and changeable, and the general cost is higher than standard parts.

Non-metallic non-standard parts:

It is the processing of some non-metallic materials, such as plastic, wood, stone, etc. In recent years, the development of the injection molding industry and plastic molds has become more and more mature, and the introduction of surface design and programming CNC has greatly improved the cost and tolerance of non-standard processing.

The above is the non-standard parts that Xiaobian introduces to you. Before precision CNC machining parts, you must understand what non-standard parts are? I hope everyone has to help. If you have any more information you would like to know, please feel free to contact us.
