We know that non-standard parts are not the same as ordinary parts. This process is generally selected when necessary.So before choosing this processing method, we must understand what kind of processing method it is.Let's find out what kind of processing method is the processing of non-standard parts?
Non-standard parts processingFirst of all, we know that non-standard parts are proposed relative to standard parts, so we need to know what is called standard parts before understanding non-standard parts. Standard parts refer to commonly used parts, such as screw parts, rolling bearings, etc., which have been completely standardized in all aspects such as structure, size, drawing, and marking. In a broad sense, it includes standardized fasteners, couplings, transmissions, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. Narrow sense includes only standardized fasteners. The standard parts commonly known in China are short for standard fasteners, which are narrow concepts, but the existence of broad concepts cannot be ruled out. In addition, there are industry standard parts, such as automotive standard parts, mold standard parts, etc., which are also broad standard parts. Non-standard parts processing professionals explain that the country has not set strict standards and specifications, and there are no other parameters beyond which other components are controlled by the enterprise. There are many types of non-standard parts, and there is currently no standard classification.
The general classification is as follows:Non-standard metal parts:The drawings are provided by the customer, and the manufacturer uses the equipment to make the corresponding products according to the drawings. Usually, the molds are mostly, the tolerance requirements, and the finish are specified by the customer. There is no certain paradigm. Products from casting to finishing require corresponding quality control, with complex procedures and great variability, and generally cost more than standard parts.
Non-metallic non-standard parts:It is the processing of some non-metal materials. Such as plastic, wood, stone, etc. In recent years, the injection molding industry, the development of plastic molds has become increasingly sophisticated, and the use of curved surface design and programming numerical control has increased the cost and tolerance level of non-standard with CNC-machining.
