Tunesi from Bulgaria, has been tortured by a hydraulic cartridge relief valve with 1μm accuracy spool for 3 months. At the beginning of this year, they developed a set of hydraulic manifold that requires the use of hydraulic cartridge relief valves, with high accuracy requirements, especially for valve spool that need to be controlled within 1μm. Tunesi chose an old hydraulic cartridge valve manufacturer in China to make samples. It took 3 months. Every time, among the 10 pcs of hydraulic cartridge relief valve testing samples, there were always several valve spools did not meet the standards. The original manufacturer gave up. The newly developed hydraulic manifold has not been successful due to poor procurement of hydraulic cartridge relief valves, and Tunesi is very annoyed. Tunesi found AAK and inquired via email,‘Can AAK control the spool accuracy of each hydraulic cartridge relief valve within 1μm?’For customers who send inquiry for the first time, whether the answer is yes or no, it is meaningless. I sent him a hydraulic cartridge pressure control valve that we customized for a Russian customer last year, with a focus on valve spool accuracy of within 1μm. Tunesi immediately sent the drawings and sample images of their hydraulic cartridge relief valve. After communication, it was learned that the original manufacturer cannot meet the spool accuracy of within 1μm. I told him that to guarantee the valve spool accuracy within 1μm, AAK has 3 steps: first, selecting high-precision equipment, second, programming and experienced technicians, one-on-one landing, and third, after processing, each valve spool needs to be inspected, screening out the valve spools exceeding the accuracy standard. After 45 days, AAK sent out 10 samples of the reprogrammed hydraulic cartridge relief valve. 2 weeks later, Tunesi informed us that their engineers had tested each spool of AAK hydraulic cartridge relief valve and they all met the standards. The hydraulic cartridge relief valve that the original manufacturer did not succeed for 3 months was finished successfully by AAK in half the time. Tunesi was very curious, and I reported to him that compared to the original manufacturer, the advantage of AAK should be in testing, because some of the hydraulic cartridge relief valves sent by the original manufacturer every time can meet the spool accuracy standard, but cannot be 100% qualified or some are unstable. AAK detected in this way: using the VX8000 series flash tester, with high- resolution optical lens, 20 million high pixel industrial camera, and autofocus. Firstly, place the precision machined valve spool on the internal platform of the instrument, set the accuracy requirements for the testing program, press the start button, and the testing instrument will start working. The lens will automatically align with the valve spool for projection. The lens can automatically locate, focus, measure, compare with the program, and then automatically determine whether the valve spool accuracy meets the standard. The entire process eliminates the need for manual labor and avoids human error. Each valve spool is tested to make sure an accuracy of within 1μm, it's not difficult. Most hydraulic cartridge valve manufacturers in China do not have this instrument, and for high-precision valve spools, they can only rely on precision machining, so the stability of valve spool accuracy cannot be guaranteed 100%. AAK hydraulic cartridge relief valve, spool accuracy within 1μm. Welcome to give it a try.

Ilona is from a hydraulic equipment company in Turkey. At the beginning of last year, less than 3 months after joining the company, he needed to purchase a batch of hydraulic pressure reducing valves for their new hydraulic equipment. Ilona placed the order with an old supplier of hydraulic pressure reducing valves that has cooperated for 3 years. After 45 days, the equipment began to be installed and debugged, but the pressure supply of the equipment was unstable. The problem lies in the leakage of the hydraulic pressure reducing valves. The specific problem lies in the error between the angle of the cone in the valve sleeve and the requirements. The engineer asked Ilona to replace the hydraulic pressure reducing valves. The manufacturer of the hydraulic pressure reducing valves said that the error control was already the limit. Ilona contacted several other hydraulic cartridge valve manufacturers and didn't get a reply. He was very helpless. Ilona noticed AAK hydraulic valve online and left a message on AAK website: Can AAK produce the hydraulic pressure reducing valves with the angle error of ± 0.8 ° of the cone in the valve sleeve? At that time, I felt that it was a customer with high quality, so I became interested. Ilona also sent the technical parameter requirements and drawings of the hydraulic pressure reducing valve. Our technical team was aware of the challenge of this hydraulic pressure reducing valve. The error of the cone angle in the valve sleeve needs to be controlled within ± 0.8 °, and the maximum axial grinding tolerance of the corresponding sealing circle is 7.5μm. These two precision requirements are difficult for most manufacturers to achieve, but our engineers are confident. 50 days later, AAK shipped the trial order of 30 hydraulic pressure reducing valve. Two weeks later, Ilona emailed that AAK hydraulic pressure reducing valve was installed on their hydraulic equipment. The problem of abnormal pressure supply had been solved and the equipment operated well. Their engineers told Ilona that the measurement error of the inner cone angle of AAK hydraulic pressure reducing valve was only 0.06 °, which was 30% higher than the standard, and the measurement error of the axial dimension of the sealing circle reached 2μm. It is 3 times higher than the standard. Their engineers wanted to know how AAK achieved it? The reason why AAK hydraulic pressure reducing valves achieved what other hydraulic cartridge valve manufacturers can't, and the two error standards are increased by 30% and 3 times, is that AAK control the quality in 3 aspects: modeling, processing and detection, which most hydraulic cartridge valve manufacturers can't do. 1. Through the process analysis of the hydraulic pressure reducing valve, our engineers establish the manufacturing error model to control the change relationship between the internal cone angle error and the grinding amount, which is the core of doing a good job of error. 2. GILDEMEISTER turning milling compound machining center is adopted, which can compensate the errors caused by tool wear and other reasons during the machining process. At the same time, the double reading head c-axis position detection technology enables the positioning accuracy of c-axis to reach 5 angular seconds, so as to ensure the minimum error of the conical surface in the valve sleeve. 3. Then use the special 3 coordinate detection device to quickly measure the axial dimension of the sealing circle of the valve sleeve, so that the manufacturing error falls within the control range, and ensure that the inner cone angle and the axial dimension of the sealing circle of the hydraulic pressure reducing valve meet the standard. AAK hydraulic pressure reducing valves, modeling, processing, testing, 3 checks for accuracy error, you can also have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-pressure-reducing-valves- aak282

A hydraulic valve giant came to talk business with you. Have you started to panic? If the other party places a large order of 1 million US dollars, which is a big business and also a big customer, what should be done to him, such as credit and price reduction? It seems to be not calm. From the perspective of quotation, I listed 3 DO principles and 3 DO NOT principles for myself and our sales department: 1. We do not pursue windfall profits, but take reasonable profits. 2. We do not do market common goods, but only benchmark SUN, HydraForce, HAWE, Honeywell and other first-line hydraulic valve brands. 3. We do not give rebates, but only provide hydraulic cartridge valves with the best cost performance In fact, many people don't understand the concept of cost performance. They think that cost performance means cheap. To understand it simply, we can use a formula: product unit price/product life=cost performance. For example, for a certain hydraulic valve, the price of Factory A is 100, and the service life of the hydraulic valve is 12 months; The price of AAK is 120, and the service life of the hydraulic valve is 24 months. The cost performance ratio of Factory A is 8.3; Similarly, the cost performance ratio of AAK is 5. This is the root cause of AAK hydraulic valve's insistence that "although the price is 20% higher, the service life is twice that of its peers". Of course, price negotiation is not only a mathematical calculation, but also requires pattern and thinking. Let me start with myself. 13 years ago, I produced hydraulic cartridge valves for trade and earned 100,000 US dollars. Of course I was happy. Later, after several years of accumulation, I made a total of 1 million US dollars, which is even more pleasant. If, after a few years or over 10 years of hard work, I have earned 10 million or 100 million yuan. Although I can't earn this money at present, think about it. As Jack Ma of Alibaba said, "Dreams must exist in case they come true". Let me take this order of magnitude as an example to analyze. When you make 100,000 yuan, what is the scope of your thinking if you buy something? What is the scope of your thinking after earning 1 million yuan? By analogy, with 100,000 yuan, the way of thinking must be different from that with 100 million yuan. When you have 100,000 yuan. would you like to buy a yacht? No. When it is 10 million or 100 million, the idea will be different. A basic truth is that when we talk about business and price, it is actually related to the cognitive pattern and is determined by the money we earn. 10 years ago, Honeywell, one of the world's top 500 companies, came to talk about hydraulic manifolds with me. They were satisfied with the first 2 trial orders, and were ready to increase the purchase from AAK hydraulic valve. The buyer specially emphasized that the delivery date should be accurate and the quality of the hydraulic valves should be good. I asked him how to understand the good quality of the hydraulic valves, and he said that just the current quality, same quality as the trial orders. The quality shall not fluctuate. It can not be the case that the first batch is good, but the third batch is not good. I don't require the quality to be best, but cannot fluctuate. At that time, I realized that the customers of industrial products wanted stable quality with fewer failures, rather than the best quality. For example, the hydraulic valve is of good quality at the beginning, but a few months later, some screw thread was adjusted, some seal ring was replaced, and the manual assembly was not in place sometimes. Although these are minor faults and can be solved as soon as possible, they are very troublesome. This refers to reliability, and they will not need to be reported for repair within a year or even longer. When talking about prices with key customers, what pattern and thinking height we should have. Take this buyer of Honeywell as an example. Because I had done business with him 3 times, I prepared some kickbacks for him privately according to the convention. He said no, really no. He said, I purchase more than 100 million yuan a year totally, and just more than 1 million yuan a year from you, why should I take rebates? When 1 million yuan of business is given to you from the Fortune 500, if you think this is a big customer, you should offer a low price, give rebates or something others, you think too much and think wrong. For the Fortune 500 or the global first-line brands, in fact, they are most concerned about your quality and service. As for the price, as long as it is not exceed their authority, it will be OK. If you used to do small business, it is difficult to do big business. Do not use the thinking of small boss to measure big customers. If a customer only purchases 2 million hydraulic valves a year, and 1 million are purchased from you, he will pay close attention to price negotiation. This has no comparability with the purchase of more than 100 million yuan a year totally but just 1 million yuan from you by the Global Top 500 companies. In his eyes, he didn't raise his eyebrows for 1 million yuan, and he didn't want to bargain with you, which is also the reason for doing business with a high-quality customer. In the process of our enterprise development, we will certainly encounter big customers to talk with you about business. Don't think of an elephant in your mind, because fixed ideas are flawed and difficult to eradicate. In general, if we often talk business with small customers and small bosses, our pattern and thinking will be limited. When encountering a big customer, we will not be confident and are afraid of big customer running away, and blindly compromised. In the end, the quality was not guaranteed, and the business with the customer died. Enterprises move forward in waves, from high to low. This is also a problem for small enterprises. For small boss, once business is good, the whole world seems to be mine. Once the business is poor, the end of the world is coming. He will be thinking hard about whether his price is too high and has more requirements for customers, so he starts to feel uneasy. Of course, this psychological quality also depends on whether you earn money. If you earn money, your psychological quality will be better. If you can't earn money, your psychological quality will be worse. Nothing can be insisted on without a sense of achievement. AAK hydraulic valve, adhering to the 3 DO principles and 3 DO NOT principles, originates from the support of the world's top 500 companies. https://www.aakindustry.com/info-detail/hy , draulic-cartridge-valves-416
