Renato comes from Brazil and recently developed a hydraulic cartridge directional control valve, which caused him trouble. In May this year, their improved hydraulic power unit required customized hydraulic cartridge directional control valves. Renato chose an old supplier to make samples. The samples were recognized by their technical department except for the valve hole accuracy of the hydraulic cartridge directional control valve. After sending samples several times, the original manufacturer still failed to achieve the stable accuracy, wasting more than 60 days and had to give up. The technical department complained that Renato did not choose high-quality hydraulic cartridge valve manufacturer for this directional control valve, which made Renato very worried. Renato left a message on AAK website: Can AAK finish 30 pcs of non-standard customized Hydraulic cartridge directional control valves in 30 days, with valve cage and hole accuracy within 2μm, cylindricity within 3μm and surface roughness within Ra0.2? Most hydraulic cartridge valve manufacturers will not give a reply for this small quantity of customization, either they don't like it or they can't handle it. After communication, we learned that the original manufacturer of the hydraulic cartridge directional control valve wasted too much time, making him very passive. I sent him some cases that AAK customized hydraulic cartridge directional control valves for customers in the past, involving detailed requirements such as accuracy, cylindricity, surface roughness, etc. Renato paid the development fee the next day, and 30 days later, AAK sent out 30 samples of hydraulic cartridge directional control valves. 2 weeks later, Renato informed us that their technical department had approved AAK hydraulic cartridge directional control valve samples, and his trouble was finally resolved. In fact, the accuracy of this hydraulic cartridge directional control valve is not too difficult. As long as the precision machining details are in place, the stability of accuracy should not be a problem. The original manufacturer's processing is not poor, and may not be thorough in the details. This hydraulic cartridge directional control valve hole is precision machined by AAK using an American vertical honing machine. The precision requirement is for military products, and AAK has also upgraded its pneumatic measuring instrument, from precision machining to measurement, in one step, without the need for replacement processes. The spindle speed of the honing machine is set between 220-250 rpm, and most hydraulic cartridge valve manufacturers prefer to choose between 260-300 rpm. However, for the stability of accuracy, AAK does not recommend this setting. After installing the hydraulic cartridge directional control valve into the fixture, it can achieve simultaneous precision machining of 8 models. The feed adopts stepless speed change, and the abrasive particles forcibly enter the machining valve hole to ensure that there are no dead corners in the valve hole. The valve cage bears constant grinding force, which is also conducive to the stability of accuracy. AAK hydraulic cartridge directional control valve, 1 equipment, 2 details, ensuring accuracy and stability, you can also give it a try!
