| Message: | Alcander is from Greece. At the beginning of this year, they developed a large volume hydraulic manifold that requires hydraulic valve blocks. Alcander made 5 samples from a local hydraulic valve block manufacturer, but there was leakage in the assembled hydraulic manifold. The main reason was the large deviation in the size accuracy of some holes on the hydraulic valve block. The original manufacturer shifted the blame, and it is normal for the pore size of the large volume hydraulic valve block to deviate slightly. Alcander was very helpless. His boss asked him to search for a new hydraulic valve block manufacturer who can produce the large volume hydraulic valve block with hole size within accuracy of ± 5μm. Alcander felt the dissatisfaction of his boss. After checking with other hydraulic valve block manufacturers for 3 days, none of them was able to ensure that the accuracy of the pore size of large volume hydraulic valve blocks can be controlled within ± 5μm. |
