| Detailed Description: | Cas No. : 5 factories failed to pass the proofing for 3 times, and AAK achieved the ± 1 μm precision hydraulic relief valve in only one time In July this year, Bowen, an Australian customer, visited 5 hydraulic valve factories before and after, and made samples of hydraulic relief valve with ±1μm inner hole for 3 times, but none of them reached the accuracy requirements. AAK sent samples and met the standard for the 1st time, Bowen finally chose to cooperate with AAK. The inner hole accuracy is not enough, which is mainly caused by the different built-in equipment of honing machines equipped by many hydraulic valve manufacturers. Conventional honing machines use diamond reamers., Because the main cutting part of the diamond reamer is at the tool head, the tool head wears quickly. After the head is worn, it is very easy to cause the size of the hole bottom to be small, resulting in the poor cylindricity of the whole hole and affecting the accuracy. This is the key to the 5% accuracy error. Many hydraulic valve manufacturers are not aware of this key point. Bowen, a purchaser from a hydraulic valve company in Australia, has an inquiry for a special hydraulic relief valve, and the inner hole accuracy must be controlled within 1μm. Bowen checked with the original hydraulic valve supplier, and got reply that only the hydraulic valve manufacturer equipped with high-precision honing machine is able to make the hydraulic relief valve with 1μm inner hole accuracy. According to the equipment configuration, Bowen has contacted with more than 10 hydraulic valve manufacturers, determined to visit 5 hydraulic valve manufacturers, and asked 3 powerful factories to sample the hydraulic relief valve. After testing and comparing the samples received from these 3 hydraulic valve factories, all failed to meet the standard. Bowen asked the manufacturer with the highest accuracy to continue to improve the proofing, and there is still ±0.1μm gap. The factory gave up and introduced AAK HYDRAULIC VALVE to him, maybe AAK can do the hydraulic relief valve with ±0.1μm inner hole accuracy. According to his hydraulic relief valve drawing, we advised that we can send 1pc hydraulic relief valve quality sample after 10 days. 5 days after AAK successfully sent the hydraulic relief valve sample, Bowen informed that the accuracy met the standard. He wanted to know why so many hydraulic valve manufacturers could not achieve ±1μm inner hole hydraulic relief valve, even if the hydraulic valve manufacturers promised to do so and they also have high precision honing machines, but several proofing did not meet the standard. How did AAK hydraulic valve achieve it? Honing machine is really helpful for the machining of high precision inner hole. Due to different equipment configuration, not every hydraulic valve manufacturer can produce the hydraulic relief valve with ±1μm inner hole accuracy. Different from conventional hydraulic valve manufacturers, AAK adopts sintered diamond tools, equipped with 15 tool position tool magazine and automatic tool change mechanism, which can automatically change tools and add deburring tools. At the same time, it has XY axis worktable, which can automatically change the hole for porous work pieces. At the same time, we have installed an online measurement system in the machine tool to automatically detect the initial diameter of the hole. The system also detects the hole distance, which can automatically alarm abnormalities and 100% eliminate human errors. Bowen's doubts are completely eliminated and asked us to do preparation for material. After he confirms the order with the customer, he will start placing order for this hydraulic overflow valve. The peers can not guarantee high precision even with the same equipment, but AAK hydraulic valve has always been the leader in precision. You can also have a small try.
