The machining process of precision parts is the process of making and processing workpieces or parts. The process of directly changing the shape, size and surface quality of the blank to make it into a part is called the machining process. For example, the machining process of a common part is rough machining - finishing - assembly - inspection - packaging, which is an abstract process of machining.

Shenzhen machinery precision parts processing skills are based on the process, changing the shape, scale, relative orientation and nature of the production target to make it into a finished product or semi-finished product. It is a detailed description of each process, each process, for example, the above mentioned, rough machining may include rough making, grinding, etc. Finishing may be divided into cars, fitters, milling machines, etc. Each process requires detailed data, such as how much roughness to reach, how much tolerance to reach.

Skilled personnel determine the selected skill process based on the quantity of products, equipment conditions, and the quality of workers, and write the relevant content into a skill document, which is called a skill program. This comparison is targeted. Each factory may be different, because the actual situation is different.

Overall, the skill flow is the program, the processing skills are the detailed parameters of each process, and the skill program is a specific processing skill written by a factory according to the actual situation.

Machinery processing plant tools have the following points:

The selection of machining skills for mechanical precision parts may be unreasonable, which will directly affect the machining accuracy, production power and economic benefits of the workpiece. Skills and equipment should be selected according to the type of production, detailed processing conditions, workpiece construction characteristics and skill requirements.

Selection of fixtures.

Single-piece and small-batch production should primarily use a variety of general-purpose fixtures and machine tool accessories, such as chucks, machine tool pliers, and indexing head numbers; for large-scale and large-scale production, special high-efficiency fixtures should be selected to improve productivity; adjustable fixtures or group fixtures can be selected for various types of medium and small-batch production.

Selection of knives

Standard tools are usually preferred. If a mechanical assembly is used, a variety of efficient special tools, composite tools and multi-edged tools can be selected. The type, standard and accuracy grade of the tool should meet the processing requirements.

III. Selection of measuring tools.

Single-piece and small-batch production should be widely used for general-purpose measuring tools, such as vernier calipers, percent measures, and micrometers. Large-scale and large-scale production should use limit measuring blocks and efficient special inspection fixtures and gauges. The accuracy of measuring tools must be compatible with the processing accuracy.
