The precision numerical control hydraulic press has no reaction from top to bottom. What's going on?
The reason why there was no response from the upper and lower parts of the precision numerical control hydraulic press could be due to the following reasons: ** 1. Regarding the hydraulic system ** 1. ** Problem with the hydraulic oil ** - The hydraulic oil is contaminated or deteriorated: During long-term use, impurities and dirt may be mixed in the hydraulic oil. When the contaminated hydraulic oil enters the pump and valve, it will affect the normal operation of the various components, resulting in no reaction from the top and bottom. For example, impurities could block the oil path, preventing the hydraulic oil from transmitting pressure to drive the hydraulic press up and down. - Insufficient oil: If there is insufficient oil in the oil tank, it may cause air to enter the oil suction port, affecting the normal operation of the hydraulic system, so that the upper and lower parts of the hydraulic press do not respond. 2. ** Failure of the hydraulic components ** - Main valve core problem: If the main valve core is stuck, whether it is in the pilot relief valve or other hydraulic valve, the main valve core will cause the pressure to be unable to be established normally or the hydraulic oil cannot flow normally, thus making the upper and lower parts of the hydraulic press unresponsive. The main valve core may be stuck in a certain position due to excessive oil dirt, wear, and other reasons, preventing the normal passage of the hydraulic oil. - Failure of the electromagnetic valve: The control of the flow direction of the hydraulic oil will be affected if the electromagnetic valve is burned out or the valve core is stuck. For example, if the electromagnetic valve could not be switched to the corresponding position normally, the hydraulic oil could not be controlled to enter or flow out of the main cylinder, which would cause the upper and lower parts of the hydraulic press to not respond. - Worn main oil cylinder seal ring: After the main oil cylinder seal ring is worn, the upper and lower pressure oil may collude with each other, resulting in the inability to establish a normal pressure difference to drive the hydraulic press up and down. - Failure of the main cylinder filling valve: The spring of the main cylinder filling valve is broken, causing the filling valve to be poorly sealed, which will also affect the normal operation of the hydraulic press, resulting in no response from the upper and lower. ** 2. Electric System ** 1. ** Power supply problem ** - Unstable power supply, voltage or current that does not meet the requirements may cause the electrical control system of the numerical control hydraulic press to fail to work normally, which in turn will affect the up and down movement of the hydraulic press. For example, a low voltage may not be able to provide enough energy for the motor or other electrical control components to drive the hydraulic system. 2. ** Control line malfunction ** - The aging of the control circuit, poor contact, or short circuit would affect the transmission of signals. For example, if there was a problem with the circuit between the operation panel and the control components of the hydraulic system, the operation instructions could not be transmitted normally, causing the upper and lower parts of the hydraulic press to not respond. 3. ** Ender malfunction (if any)** - If the hydraulic press's servo-system had an programmer, the damaged or loose programmer would cause the system to lose its position feedback, affecting the normal operation of the hydraulic press, including up and down movement.

Ten Pithy Words of Numerical-Control Program
The following are some of the chants for numerical control programming: 1. Planar processing, flat bottom priority, less ball cutter selection, saving time key. 2. Open the thick broadsword, the remaining material knife, the remaining amount is the same, and then use the light knife. 3. The bronze workers were rough, the alloy throwing knives were used, and the white steel was rarely used. The speed of rotation was not high. 4. Copper workers clean the angle, first check the R angle, the size of the ball knife, according to the needs of the selection. 5. Calibrating the surface of the table, the four corners of the gong are flat, the slope is rounded, and the inclined knife is used for processing. 6. If the work piece is too high, open it in layers and choose a reasonable route with a long knife and a short knife. 7. To be able to go with the finisher instead of the ROUGH, WCut programming, this was the way of thinking. 8. Knife path programming was mainly simple. It circled around the same height and walked as little as possible. 9. Program the tolerance, set it reasonably, drive the rough and fine car, and weigh the difference. 10. The shape of the knife is smooth, rough first and then fine, the work piece is too high, the edge first and then the bottom. " When a programmer meets a psychologist " is equally exciting.

What is the role of contactors in the numerical control machine tool?
In a numerical control machine tool, the functions of the contactors were as follows: 1. It is used to control the motor, quickly cut off the main AC and direct current circuits, and frequently open and close the high-current control circuit. 2. It can be used to control factory equipment, electric heater, machine tools, and various power units and other power loads. It can not only connect and cut off the circuit, but also provide low-voltage protection. Contactors were known as contactors in English, and their pronunciation was English. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the top stories in hydraulic fracturing?
Well, some of the top stories in hydraulic fracturing could be the exploration of new areas for fracking. Companies are always on the lookout for new shale deposits that are suitable for hydraulic fracturing. This not only expands the industry but also has implications for energy security. Additionally, there are stories about the safety measures in hydraulic fracturing. Ensuring the safety of workers during the fracking process is crucial. This includes protecting them from potential chemical exposures and the high - pressure situations involved in the operation. And, of course, stories about the competition between different energy sources. As the world moves towards more sustainable energy, hydraulic fracturing has to compete with renewables, and this is a big topic of discussion.
I recommend a few books on programming for beginners in numerical control
Did you recommend any books on the numerical control lathes?
A novel that produces five-axis numerical control machine tools
I recommend " Infinite Fusion of the Heavens." It was a novel written by Liu Xiaowu about the infinite heavens. It was like a game war, starting with a small village, merging and annexing other villages, and various races fighting for survival. It was super exciting. " Industrial Overlord " had to be written by Qi Cheng. Lin Zhenhua, a graduate student of the Mechanical Department, traveled to 1979 and became a young factory worker. He built a heavy industrial group with his own abilities. The book had the aura of that era. Although some of the plots were ridiculed, it was still a classic industrial novel. 'Snatching Twelve Talismans at the Beginning, Invincible in the Heavens and Realms' was not bad either. It was written by a 70% done salted fish. The protagonist transmigrated into a defective dragon egg at the beginning and relied on the system to transmigrate through the heavens and devour resources to evolve. At the age of eight, he was comparable to the Dragon King and could travel through many interesting worlds. You could also watch " A Hundred Years in Prison ", a wuxia fantasy novel written by Fat Tiger 159. The name was super interesting. The male lead was funny and nonsensical, while the female lead was a cold-faced God of War. " Industrial Empire " was written by King Sewarn. The male protagonist obtained a future intelligent life and started building heavy industries from the machinery factory. If you like industrial industries, you can try them.

How long does it take to learn numerical control programming?
The basic learning of a numerical control programming apprentice usually took three months. If the company required it, it would take half a year, but this depended on the individual's comprehension ability. In the longer term, for students who had just graduated from school, if they wanted to be a numerical control programmer, they would need to have a wealth of processing experience. It would take a short one or two years, and a long three or five years to meet the requirements. If it was a person who had a certain foundation in machine processing and knew how to operate a machine, the purpose of learning was to operate a machine. Two hours would be enough.
