The technological process of large-scale machining mainly refers to the steps of manufacturing and processing of workpieces or parts. When operating, the method of machining is mainly used to directly and effectively change the shape, size and surface quality of the blank to make it a part. The process is called the machining process. For example, the processing process of an ordinary part is rough machining-finishing-assembly-inspection-packaging, which is a general process of processing.

The process of large-scale machining is to effectively change the shape, size, relative position and nature of the production object on the basis of the process to make it a finished product or semi-finished product. It is a detailed description of each step and each process. For example, as mentioned above, rough machining may include blank manufacturing, grinding, etc. Finishing machining may be divided into turning, fitter, milling machine, etc. Each step must have detailed data, for example, how much roughness should be achieved and how much tolerance should be achieved.

Large-scale mechanical processing will effectively determine the process according to the quantity of products, equipment conditions and the quality of workers, and write the relevant contents into process documents, which are called process regulations. This is more targeted. Each factory may be different, because the actual situation is different.

The large-scale machining procedure is one of the process documents that stipulate the machining process and operation method of parts. It is to write a more reasonable process and operation method into a process document in accordance with the prescribed form under specific production conditions. After approval, it is used to guide production. Machining process regulations generally include the following: the process route of workpiece processing, the specific content of each process and the equipment and process equipment used, the inspection items and inspection methods of workpieces, cutting dosage, time quota, etc.

In the process of formulating the technological process, large-scale machining often makes effective adjustments to the contents that have been preliminarily determined in front, so that its economic benefits can be improved. In the process of implementing the technological procedures, unexpected situations may occur, such as changes in production conditions, the introduction of new technologies and new processes, and the application of new materials and advanced equipment, all require timely revision and improvement of the technological procedures.

Composition of data machine

The composition of CNC machine tools CNC machine tools are generally composed of input and output equipment, numerical control devices (CNC), servo units, drive devices (or actuators), programmable logic controllers (PLC) and electrical control devices, auxiliary devices, machine tool bodies and measuring devices.

Automatic Lathe in Taiwan: Current Status of Compound Machining Machine Tools

Composite processing machine tools generally have these characteristics: fewer settings, sometimes even one-time; Complex workpieces do not need to be processed on multiple machine tools; Reduce the number of clamping workpieces; The number of machine tools on the processing site is reduced, and there is no need to invest a lot on the site.

Cd pattern screws must choose stainless steel material?

The benefits of CD pattern screw probably need not be said, it can be seen in our mobile phone parts. But do you find that the CD grain material is made of stainless steel, carbon steel, aluminum material can not be selected? Let's talk about why the CD grain screw must be made of stainless steel.
