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

Process Analysis of CNC Machining Parts Drawing

Process Analysis of CNC Machining Parts Drawing

 

(1) The method of dimensioning in the drawings of CNC machining parts

 

The size on the part drawing is an important basis for manufacturing and inspecting parts. In the production (Produce), the size of the part drawing is required to be free of any errors. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, laser cutting china, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In addition to correct, complete, and clear requirements for marking the size on the part drawing, rationality should also be considered. It should not only meet the design requirements, but also facilitate processing and measurement. ? Regarding dimensioning, it mainly includes functional dimensions, non-functional dimensions, nominal dimensions, basic dimensions, reference dimensions, repeat dimensions, and so on. The dimensions marked on the part drawing are complete and correct, making it easy for the processor to analyze, measure, and process. According to these dimensional accuracy (accuracy), the blank is determined to be Φ95*250mm and the material is 45 steel.

 

(2), analyze (Analyse) the geometric elements of the contour of the CNC machining aluminum parts

 

The contour of the part is mainly composed of cylindrical surface, spherical surface, groove (gōucáo), keyway, inner hole and so on. CNC machining is a process method for parts processing on CNC machine tools. The process regulations of CNC machine tool processing and traditional machine tool processing are generally the same, but significant changes have also taken place. A machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batches, complex shapes, and high precision, and to achieve high-efficiency and automated processing.

 

(3) Analyse the structure and craftsmanship of CNC machining parts

 

The part is a slender shaft. The slender shaft has the characteristics of small diameter and too long length. The length of the suspension body is too long when processed, and it is easy to vibrate the knife or the surface roughness value of the processing is too low, so it must be used for processing. Auxiliary tool holder and auxiliary fixture. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, metal forging and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. There is also something to pay attention to during heat treatment, because it will deform after being hardened by cold work, resulting in a bowing or S-shape.

 

(4) Analyse the precision (precision) and technical requirements of CNC machining parts

 

The precision (precision) and various technical requirements of this part are complete and reasonable

The CNC machining precision (precision) in this process is required to be high. This requirement can be met in the CNC machine tool (attribute: automated machine tool). The machining is divided into three types: rough machining, semi-finishing and finishing. The procedure is carried out.

. The left end of the outer circle size of Φ90 in the figure has higher position accuracy (precision) requirements. All procedures in this section should be completed in one clamping process, except for the keyway.

. For surfaces that require high surface roughness, the circumferential constant linear speed should be used for cutting.
