| Message: | AAK hydraulic valve block, from a five axis CNC machining center, is milled with a thread milling cutter, completely replacing the traditional radial drilling machine processed with a formed tap, and the thread surface roughness value is Ra1.6μm. The traditional Ra is at 12.5μm. Ra alone has increased sevenfold. Archie purchased AAK hydraulic valve blocks, which not only stopped losing more than 30,000 dollars, but also made an additional profit of more than 10%.
For the hydraulic valve block with conical pipe thread, the pipe thread cannot completely seal oil, which is an industry problem. The vast majority of hydraulic valve block manufacturers use traditional radial drilling machines and formed taps for processing. The surface roughness of their threads is a "mine", especially the processing of offset holes, which is a hot potato.
