| Message: | Chase is the purchaser of a hydraulic valve company in the United States. The purchase of hydraulic valves has been very smooth for 2 years, but a recent order for hydraulic valve blocks made him very difficult. In the sample approval stage of the hydraulic valve block, the samples had been revised for 4 times, but during the test, it was still found that there were different degrees of burrs at the cross holes of the valve block. Although the last sample had been greatly improved, there were still subtle burrs, which was easy to cause system faults such as unbalanced pressure regulation. His customer did not accept the pre-production sample of hydraulic valve block, and the hydraulic valve manufacturer was still exploring the solution of burr. The customer was pushing, the boss was asking, and the manufacturer had no effective plan. What should he do? He had trouble in sleeping and eating because the delivery date would not wait for him.
Chase found AAK hydraulic valve through Google search. He emailed us some common questions about the hydraulic valve block. I felt that he had encountered a problem, but he was not sure whether I could solve it and also afraid of wasting time. I directly asked him to tell me the problem of the hydraulic valve block. If it could be solved, I would make the sample directly for him to test.
How to remove burrs? Different manufacturers have different treatment processes. The hydraulic valve factory cooperated with Chase uses manual method to remove burrs. The work piece is polished and deburred with tools such as file, sandpaper and grinding head. This method has blind spots, general effect and low efficiency, especially for the burrs in complex cross holes.
After Chase received our hydraulic valve block sample, he did simulation test. The previous problems such as unbalanced system pressure regulation were solved. The system pressure regulation became more sensitive and the problem was smoothly solved. Chase asked us to help deliver the goods as soon as possible.
