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

Ways to improve the processing efficiency of precision parts

Earlier, we introduced to you where the main advantages of precision parts processing are reflected. Today https://cncmachining.wiki/ will introduce some methods to improve the efficiency of precision parts processing:

In the processing of non-standard equipment parts, common problems such as accelerated tool wear, poor processing appearance, and difficulty in chip removal will occur. This has seriously affected the quality, production cycle and processing cost of precision parts of such materials.

The processing of non-standard equipment parts requires super-lubricated processing appearance and high processing accuracy, which requires the knife to have a high standard life. Whether the tools of CNC precision processing plants are worn or not will be based on whether the processing surface quality is reduced or not. The standard life of diamond tools is very high, and the tool wear is very slow during high-speed cutting. Therefore, the cutting speed is not restricted by the tool life during ultra-precision cutting, which is different from the general cutting rules.

The cutting speed selected for non-standard equipment parts processing practice is often selected according to the dynamic characteristics of the ultra-precision machine tool used and the dynamic characteristics of the cutting system, that is, the speed with the smallest vibration is selected, because the surface roughness is the smallest and the processing quality is at this speed. The highest, to obtain high-quality non-standard machining appearance is the primary question for non-standard equipment parts processing. Good quality, especially good dynamic characteristics, ultra-precision machine tools with low vibration can use high cutting speeds and increase processing power.

The selection of processing parameters of non-standard equipment parts mainly includes the selection of cutting tool viewpoint, the selection of cutting speed, the selection of cutting depth and feed speed, etc. From past experience, we know that if you choose a larger rake angle when processing plastic materials The tool can effectively inhibit the formation of built-up edge. This is when the rake angle of the tool increases, the cutting force decreases, the cutting deformation is small, and the contact length between the tool and the chip becomes shorter, which reduces the basis for the formation of built-up edge.
