What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the requirements for the division of CNC machining processes?

When Cnc Machining processes are divided, it must be flexibly controlled based on the structure and manufacturability of the parts, the functions of the CNC machining center machine tools, the number of parts CNC machining content, the number of installations and the production organization of the unit. It is also recommended to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but must strive to be reasonable. The division of processes can generally be carried out according to the following methods:

 

When CNC machining is divided into processes, it must be flexibly controlled according to the structure and manufacturability of the parts, the functions of the CNC machining center machine tools, the number of parts CNC machining content, the number of installations and the production organization of the unit. It is also recommended to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but must strive to be reasonable. The division of processes can generally be carried out according to the following methods:

 

1. Tool centralized sorting method.

 

This method is to divide the process according to the tool used, and use the same tool to process all the parts that can be completed on the part. In order to reduce the tool change time, compress the idle time, and reduce unnecessary positioning errors, the parts can be processed according to the method of tool concentration, that is, in one clamping, use one tool to process all the parts that may be processed as much as possible, and then Change another knife to process other parts. This can reduce the number of tool changes during the plasctic machining, reduce idle time, and reduce unnecessary positioning errors.

 

2, the order of processing parts.

 

The structure and shape of each part are different, and the technical requirements of each surface are also different. Therefore, the positioning methods are different during processing, so the process can be divided according to the different positioning methods.

 

For parts with a lot of processing content, the processing part can be divided into several parts according to its structural characteristics, such as inner shape, shape, curved surface or plane, etc. Generally, the plane and positioning surface are processed first, and then the hole is processed; the simple geometric shape is processed first, and then the complex geometric shape is processed; the parts with lower precision are processed first, and then the parts with higher precision requirements are processed.

 

3, the roughing and finishing are sorted in order.

 

When dividing the process according to factors such as the machining accuracy, rigidity and deformation of the part, the process can be divided according to the principle of separating rough and finishing, that is, roughing and then finishing. At this time, different machine tools or different tools can be used for processing; For parts that are prone to deformation during CNC machining, due to the deformation that may occur after rough machining, it needs to be corrected. Therefore, in general, all the rough and finishing processes must be separated.
