For a hydraulic manifold block with many deep holes and great difficulty in finishing, the original hydraulic manifold block manufacturer worked on the trial order for 15 days. After 15 days of processing, the single hole processing cost increased by nearly 30%, and the production efficiency was only 1/5 of the normal. Leon understood that the processing cost was not affordable and had to change the manufacturer of the hydraulic manifold block. After AAK took over, the welding reamer with special groove and blade design was used to replace the conventional hard reamer. The linear speed was up to 680m/min, the production efficiency was increased by more than 10 times, and the processing cost of single hole position was only 1/3 of that of the original hydraulic manifold block manufacturer
Leon, from Germany, is one of our old customers, mainly purchases hydraulic valves. Leon contacted me a few days ago and asked me to try a special hydraulic manifold block test order, and specifically reminded that the original manufacturer used a hard reamer in the finishing process, the roughness can only reach about Ra1.6, the linear speed is not higher than 50m/min, and the tool processing service life is not more than 300 pieces. The aperture tolerance of this hydraulic manifold block shall be ± 0.005mm, and the hole wall roughness shall meet Ra0.8 and Ra3.2 at the same time. If the conventional coating hard reamer is used, the machining accuracy is difficult to reach the standard, and the service life of the tool is very short, which greatly increases the single hole processing cost, that is, increases the customer's purchase cost.
After 3 days of research and discussion, we replied Leon that AAK was 90% confident. After 25 days, AAK sent 6 hydraulic manifold block samples. 2 weeks later, Leon told us that the precision of AAK hydraulic manifold block fully conforms to the system error standard, and hoped that we could provide a competitive development price. Leon was surprised that how did AAK hydraulic manifold block achieve that the hole processing cost was 1/3 of the original manufacturer's, and the production efficiency was more than 10 times higher?
In view of the structure and processing technology of the hydraulic manifold block, AAK technical team realized that the traditional hard reamer processing technology was not suitable for the processing of this hydraulic manifold block. Through repeated design verification and trial cutting, it is finally determined that the welding reamer with special groove and blade design should be used to replace the conventional hard reamer, with the linear speed of 680m/min, the efficiency increased by more than 10 times, the tool processing service life increased from 300 pieces to 2,500 pieces, and the processing efficiency and tool service life increased significantly.
