AAK hydraulic valve, adopts URMA reaming technology of Swiss quality to process the valve spool hole in the hydraulic valve block. With the precision, reliable and efficient URMA reaming technology, the high precision of the valve spool hole of the hydraulic valve block is ensured, and the stable surface quality and tolerance range are maintained in the whole hole diameter. Brody, an American customer, had asked about no less than 20 hydraulic valve manufacturers, but no hydraulic valve block manufacturer had the ability to undertake his order for hydraulic valve blocks with special valve spool holes. After 3 days of communication with AAK hydraulic valve, he directly placed a trial order for 200 hydraulic valve blocks.

The valve spool hole is the key point in the hydraulic valve block. Many hydraulic valve block manufacturers do not have their own high precision equipment, so they can only process outside. Generally, the outside processing centers only process according to the process parameters, and rarely consider the properties, use scenarios, and service life of machining components. It is difficult to continuously and stably grasp the diameter dimensional tolerance of valve spool hole, coaxiality, cylindricity and roughness. Once such a hydraulic valve block is used, it will directly affect the quality and operation stability of the whole hydraulic system.

Brody, who needed to purchase a batch of special hydraulic valve blocks, asked no less than 20 hydraulic manufacturers, but no manufacturer was able to undertake this order. Brody browsed our website, www.aakindustry.com, emailed us, listed us the process parameters of the valve spool hole in the hydraulic valve block, and the internal anatomy diagram, and asked if we could do it? This hydraulic valve block had high precision requirements due to the existence of most segmented structures in the valve spool hole, small diameter dimensional tolerance of the valve spool hole, and many precision requirements such as coaxiality. This processing was very difficult. I was also curious why Brody didn't ask us like other customers what tools we used. Brody said he didn't need a tool for machining holes, but holes.

When Brody learned that we AAK hydraulic valve could meet the process requirements of his hydraulic valve block and was willing to make a sample for him to test, he seemed to feel that perhaps only AAK hydraulic valve could help him solve the problem of this hydraulic valve block. When he received our hydraulic valve block samples, he informed us by email on the 3rd day that the test results of hydraulic valve block met the requirements. He was also curious about how we AAK hydraulic valve achieved it.

AAK hydraulic valve, adopts URMA reaming technology of Swiss quality to process the valve spool hole in the hydraulic valve block. With the precision, reliable and efficient URMA reaming technology, the high precision of the valve spool hole of the hydraulic valve block is ensured, and the stable surface quality and tolerance range are maintained in the whole hole diameter. The 4 process points of URMA reaming technology ensure that the hydraulic valve block meets Brody's special requirements.

1. Guide bar support: the guide bar support structure ensures that the tool is in the most correct position at all times during cutting.

2. Cooling requirements: the concentration of coolant shall be 12% ~ 15%, the guide bar cutter must be fully lubricated, and the cooling pressure shall be sufficient to ensure smooth chip removal.

3. Runout requirements: the flange interface is adopted, and the runout can be adjusted in both radial and axial directions to ensure that the tool is always in the best state during cutting, and the error control can remain unchanged.

4. Blade replacement: when the blade is worn and the hole diameter is less than or equal to the diameter of the support strip, replace the blade.

Brody was in a good mood after receiving our process explanation and finding the hydraulic valve block pass the test. He directly placed a trial order for 200 hydraulic valve blocks, and the communication time was only 3 days.

AAK hydraulic valve, with guaranteed accuracy, you can also have a small try.
