William is a purchaser of a hydraulic equipment company in the United States. At the beginning of last year, a South American customer wanted to customize a drilling machine for geological exploration. The South American customer promised to order this equipment for a long time if it has excellent performance and stability. The boss asked the engineers to design and test samples. According to the working conditions, the maximum pressure of the hydraulic system is 450bar or above, which has a very high requirement on the pressure resistance and stability of the hydraulic pilot operated pressure control valves. When William received the task of purchasing this hydraulic pilot operated pressure control valve, he felt a big pressure, because the pressure resistance of normal hydraulic pilot operated pressure control valve is basically 250bar, and the maximum pressure resistance provided by previous hydraulic valve manufacturers was also only 380bar. He asked all the hydraulic valve manufacturers that he contacted before, they basically replied that according to this working condition, their hydraulic pilot operated pressure control valve can only ensure a service life of 3 months, but the customer asked for a service life of 1 year. William also contacted the local hydraulic valve manufacturers in the United States. They told him that he could not promise a service life of 1 year for this hydraulic pilot operated pressure control valve. They can only test the samples first, then to know the service life. One of his other hydraulic valve manufacturers in China introduced AAK to him. He told William that AAK shipped a hydraulic pilot operated pressure control valve for a working condition of maximum pressure 450bar before, but the service life required by that customer is 6 months. After receiving the drawings of the hydraulic pilot operated pressure control valve from William, AAK technical team found that the requirements of this hydraulic pilot operated pressure control valve were higher than those of our last shipment. The conventional No. 45 steel could not meet the requirements, so we had to find special steel. Later, after 5 times of material selection and testing, 2 months later, AAK internal sample testing was successful by using a German steel with high wear resistance and high fatigue resistance. After sending the samples of hydraulic pilot operated pressure control valve, we have been waiting for news from William. William said that no news from customer is the best news. Last month, 1 year after AAK samples were sent, William emailed us that he would order 100 hydraulic pilot operated pressure control valves at one time. The quality standard is the same as that of the hydraulic pilot operated pressure control valves sent last year. Because the other hydraulic valve manufacturers in China can only ensure the service life of 3 months, he did not request those manufacturers to make samples, but only asked a hydraulic valve manufacturer in the United States and AAK hydraulic valve to make samples for this hydraulic pilot operated pressure control valve at the same time. The test result from their customer is that the samples of hydraulic pilot operated pressure control valves provided by the hydraulic valve manufacturer in the United States needed to be treated after being used for 12 months, while the condition of AAK sample is still normal after 1 year. Therefore, they choose AAK as the supplier for this hydraulic pilot operated pressure control valve and think it is difficult to find a second one The core of this hydraulic pilot operated pressure control valve is material and heat treatment. AAK adopts 20CrNi2MoV high carburizing bearing steel imported from Germany, combined with carburizing pretreatment process, through secondary quenching + cryogenic treatment + low temperature tempering process, which is cooled to 650 ~ 700 ℃ and discharged after cooling to 450 ~ 500 ℃. The micro hardness is 237 ~ 247 HV, and its wear resistance and contact fatigue performance are increased by more than 3 times. AAK customized hydraulic pilot operated pressure control valve, is suitable for high pressure working condition and durable, welcome to have a small try! https://www.aakindustry.com/info-detai , l/pressure-control-valves-aak143

A high-precision hydraulic manifold block, has been adjusted by the original manufacturer for many times, the benchmark error of the hydraulic manifold block still cannot be eliminated. AAK took it over under the introduction of old customer, optimized the original processing technology, and added the finishing boring process before the vertical drilling sequence to re calibrate the positioning of the V-shaped block, so that the benchmark error of the hydraulic manifold block was controlled at 0. Tom sent the order of the hydraulic manifold blocks of more than 20000 dollars. Tom is from Holland. They should be the top 3 of the hydraulic companies in Holland. Tom, introduced by his friend Mathias, sent us an inquiry for hydraulic manifold block. After communication, we knew that Tom learned from Mathias that AAK hydraulic technology has changed every year in recent years, and have supplied hydraulic manifold blocks to the world's top 500 companies, so he contacted me. Tom told us the problems with the original hydraulic manifold block manufacturer. Turning Φ 215mm excircle and Φ 88mm inner hole, outer circle center as benchmark, turning Φ 205h8 uses a special fixture, which also uses the outer circle center as the reference for turning. There should be no datum misalignment error, but the hole position is out of tolerance. After 2 days of discussion, AAK hydraulic engineers basically determined that it was caused by the positioning error of V-shaped block in the machining center. Tom was surprised by our analysis and half believed it. I told him that AAK was willing to sample this hydraulic manifold block. If the parameters were not up to standard, the development cost would be refunded. After 30 days, AAK sent 5 hydraulic manifold block samples. 2 months later, Tom sent us the official order for hydraulic valve block of more than 20000 dollars. The reason why AAK can effectively solve the positioning benchmark error is that starting from the production process, it deliberately adds the finishing boring process before the vertical machining sequence drilling to re calibrate the positioning of the V-shaped block. After optimization of AAK hydraulic manifold block: vertical machining center, turntable rotates to 90 ° fine boring φ 88H7 inner hole → drill φ 215mm on cylindrical end face φ 25mm hole allowance → boring φ 25mm hole → rotary table rotates to 0 ° for fine boring φ 110H7 hole → finish milling φ Upper end face of 53mm hole → drill φ On 205mm excircle end face φ 22mm hole allowance → boring φ 22mm hole → rotary table rotates to - 90 ° fine boring φ 88H7 inner hole → drill φ 215mm on cylindrical end face φ 25mm hole allowance → boring φ 25mm hole. The optimized processing technology can reduce the influence of datum movement error to zero, and the positional and vertical accuracy can be better guaranteed. AAK hydraulic manifold block, zero benchmark accuracy error, welcome to try! https://www.aakindustry.com/info-detai , l/hydraulic-manifold-blocks-aak454

AAK hydraulic pilot operated relief valve adopts diamond reamer technology, and the valve hole accuracy of hydraulic relief valve is guaranteed to be within 3μm, the surface roughness reaches Ra0.2-0.4. AAK hydraulic relief valve is sensitive and the valve spool is not stuck. It exceeds 99% of its peers. Nick, who has cooperated for 6 years, still orders back from AAK. Nick is the buyer of John Deere company. He has cooperated with AAK hydraulic valve for more than 6 years. The boss trusts him very much. Recently, a batch of bulldozers they sold to South Africa were complained that the hydraulic system was unable to start. The problem was that the valve body hole roundness of the hydraulic pilot operated relief valve was poor and the valve spool was easy to get stuck. The boss felt very strange. In the past 6 years of cooperation with AAK hydraulic valve, there was no complaint about the hydraulic pilot operated relief valve. After checking, he knew that Nick found a new supplier for this hydraulic pilot operated relief valve, which is 17% cheaper than AAK. The approval samples of hydraulic relief valve provided by the hydraulic valve manufacturer are qualified. Unexpectedly, the accuracy of hydraulic relief valve shipment is uneven. The boss asked Nick to contact AAK hydraulic valve, reproduce the hydraulic relief valves, and ship them directly to South Africa. We were a little surprised when we received an email from Nick to purchase 100 hydraulic relief valves and ship them directly to South Africa. Nick frankly told us that there were problems with the shipments from the original hydraulic relief valve manufacturer and needed the help of AAK to solve the customer complaints together. The difficulty of customer is the difficulty of AAK. We give priority to the production of this batch of hydraulic relief valves. After 35 days, the South African customer of Nick received the replacement of hydraulic pilot operated relief valves, and the whole after-sales process satisfied the customer. Nick sent an inquiry for a new hydraulic relief valve a few days ago. He specially said that his boss asked him to take AAK as the first choice for future hydraulic relief valves, because the quality of AAK hydraulic relief valve has not had any quality complaints in the past 6 years. Comparing the hydraulic relief valves produced by AAK with its peers, it will show why AAK hydraulic relief valve is sensitive and the valve spool is not stuck, which exceeds 99% of its peers. Nick, who has cooperated for 6 years, still orders back from AAK. For the machining of hydraulic relief valve hole, most peers use rigid Boring Reamer or stepped reamer, which has high production efficiency, but the hole accuracy is generally 7μm or above, it is difficult to stabilize on one data, and the roughness is fluctuated at the range of Ra1.6-3.2. AAK uses the diamond reamer to process the valve hole of hydraulic relief valve. In the grinding process, the reamer moves regularly in circumference and axis, and the metal is cut completely without trace with the micro edge of diamond particles. The accuracy of the valve hole of the hydraulic relief valve is guaranteed to be within 3μm, the surface roughness reaches Ra0.2-0.4, which almost avoids the roundness and cylindricity errors of the valve hole, improves the coaxial accuracy, and unifies the accuracy data. AAK hydraulic relief valve is sensitive, and the valve spool is not stuck, exceeding 99%. The 17% more expensive AAK hydraulic relief valve, has its unique valve hole processing, incomparable quality.
