At the beginning of last month, as soon as I turned on the computer after arriving at the office, I saw an email from Berton with the theme of "damn hydraulic valve block", which surprised me. I thought there was something wrong with the hydraulic valve block purchased by Berton from AAK. After reading the email, I learned that he purchased the hydraulic valve block from a German company. There was a leakage problem in the two proofing, and each time the sampling modifying process was very slow, which affected the commissioning of the whole equipment. The technical team had complained to the boss, who was a little annoyed and asked him to get the modified sample of the hydraulic valve block approved for the third time within 1 month. The German factory advised that the third hydraulic valve block sample could be solved at one time, but 1 month was not enough, which made Berton very helpless.
 
Because this series of hydraulic valve blocks has been purchased in Germany before, Berton has to wait for the revised sample from the German factory, and find a new hydraulic valve block supplier at the same time. He wanted to check if AAK has any good suggestions. I asked him to send the hydraulic valve block design drawings to us, note the working conditions, and also send the second unconfirmed hydraulic valve block samples to AAK for comparison.
 
According to Berton's drawings and the samples of the hydraulic valve block from the German factory, the finished product quality is good and worthy of being produced by the German factory. The root cause of the leakage is that the perpendicularity tolerance between the thread of the hydraulic valve block and its mating surface reaches 0.08mm, which should not be higher than 0.05mm according to the working conditions. This tolerance dimension is difficult to control and has high requirements for the operator, We recommend changing the system design of the hydraulic valve block. If it is successful, samples of hydraulic valve blocks can be sent within 25 days. Berton has no better choice but to wait passively.
 
5 days after sending the sample, Berton was excited to inform that the sample of AAK's newly designed hydraulic valve block met the system requirements of the equipment and did not leak. The accuracy and efficiency of the hydraulic valve block were both improved compared with the hydraulic valve block of the German factory. Berton is curious about why AAK dares to change the design of the German factory. Even the engineers of his technical team admire the new design of AAK hydraulic valve block.
 
Based on the design of the German factory, AAK changed the whole oil circuit design. Some valve holes can be combined with the same unit to perform a specific type of control function, which is conducive to improving the execution efficiency of the hydraulic power system. At the same time, the pressure regulation loop, flow control loop and power supply loop are newly designed. The reason why AAK dares to make such changes is that we have an efficient machining center, MIKRON machining center and AMEC sinking drilling and milling cutter. This combined cutter can directly complete the processing of the dimensional accuracy required by the diameter of the threaded bottom hole and the sealing ring, and also the processing of the surface finish. Moreover, it has central internal cooling and allows faster cutting. In this way, man-made errors are eliminated in accuracy.
 
Berton said happily that he could finally ignore the arrogance of the German factory. The boss asked him to transfer the order directly to AAK, and the price was cheaper than that of the Germany factory. The boss was very satisfied with Berton's idea of finding a new supplier of hydraulic valve blocks.
 
AAK can not only make high-precision hydraulic valve blocks, including different types of hydraulic valves, but also help you with design solutions. You can try a small order.
