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

Calculation of high unit braking energy of vehicle retarder

 

The anti-overspeed performance of the vehicle retarder is reflected by testing the high unit braking energy of the retarder. For the three-part reducer, the unit braking energy of the reducer design is h=0.12 (m/m), and in rainy days or oil-stained wheels, it will be reduced to the level of 0.10 and 0.03 (m/m) respectively. If the unit braking energy of the reducer with the brake beam installed in the new design is guaranteed to be greater than the design value of the reducer, the problem of overspeeding of the dump truck can be completely solved. The test method is to calculate the acceleration of the vehicle through the radar speed curve of the control system, and calculate the unit braking energy high.

Through systematic analysis of the causes of overspeeding and braking noise of the retarder, combined with laboratory and field tests to test the oil-water sensitivity and noise reduction performance of the materials, the composition, organization, structure and hardness of the test materials are constantly changed. And so on, * finally successfully developed the retarder anti-over and noise-reducing brake beam.

The anti-super noise reduction brake beam has low sensitivity to oil and water, and has obvious anti super effect. The unit braking energy is high and fully meets the design requirements, which effectively guarantees the safety of shunting operations.

Compared with ordinary brake rails, the noise reduction efficiency reaches 100%, of which more than 80% can reduce 20dB (decibel), the highest decibels are distributed below the frequency of 2kHz, and there is no sudden change in the decibels from 0 to 10kHz, no more The harsh screaming noise with high sound pressure level greatly improves the noise environment around the marshalling yard, which is beneficial to the physical and mental health of the operators. During a major repair period, there is no need to replace the brake beam, only the segmented composite brake pads need to be replaced, and the total cost is low. Moreover, the splint is light in weight and easy to replace. By adjusting the composition, organization, structure and hardness of the brake splint material, the inner brake splint of the target brake position reducer can be used for 5 to 8 years, and the outer brake splint can be used for 3 to 5 years, which can meet the requirements of use.
