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 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

The amount of wear between the mating parts is very small

In the process of highway construction, a large number of construction machinery and construction machinery combinations are required. Due to the gradual deterioration of their technical conditions during use, the engine power decreases, fuel consumption increases, exhaust gas exceeds the standard, transmission component gaps increase, and operating mechanisms do not work well. An error occurs in the working device. This is mainly due to the wear of the parts, the structure of the parts, the processing quality of the materials, the working conditions (climate and construction environment), the quality of the fuel and lubricating materials, the reasonable degree of use, the operation methods in the construction, the configuration of the machinery, and technical maintenance Caused by repair quality, etc., we will analyze separately below. Wear and damage of construction machinery parts During the use of the machinery, wear occurs due to the friction between the parts. Under normal circumstances, the wear process of parts is divided into D stages. **The stage is the running-in stage. The surface of the processed parts is rougher before running-in, so the wear is larger. Such as the running-in period of a newly purchased mechanical vehicle. During this period, with the increase of time, the working surface of the parts gradually wears out, so that the fitting clearance between the parts reaches the initial clearance clearance. The second stage is the normal working stage of the parts. After the mating parts are run-in, the surface of the parts is smooth and smooth, and the mating clearance reaches the design standard. During the use of the machine, the amount of wear between the matching parts is very small, and the matching gap grows slowly. The third stage is the accident damage stage. During the use of the machine, due to the increase in the fit gap, impact load is generated, the lubrication conditions of the parts become worse, and the sharp increase in wear may damage the parts and cause mechanical accidents. Mechanical wear Mechanical wear is caused by the friction between the surfaces of the parts. Although the surface of the parts is machined, it is still impossible to be absolutely smooth. When the surfaces of the parts are in contact with each other, they are uneven and easy to embed in each other. When the parts move, the raised metal particles are constantly falling off. When the fit gap increases to a certain extent, the parts will increase due to the impact load, and the lubrication conditions will be destroyed and wear will continue to increase.
