Kuplin is from a Russian hydraulic equipment manufacturing company, he has purchased hydraulic valve blocks from China for a long time, which is also relatively smooth. However, a hydraulic valve block he purchased at the end of last year put him into a hard situation.

 

A batch of hydraulic climbing cars sold by their company were complained by customers. During the routine maintenance of the hydraulic system, several cartridge valves on several equipment cannot be taken down, the nose end is stuck in the socket of the hydraulic valve blocks, and there is a small amount of leakage around the socket. The hydraulic valve block manufacturer replied that when processing the hydraulic valve blocks, the technician processed the nose end of the socket into a conical surface, which made it easy to install and difficult to take down, and also affected the seal, resulting in a small amount of leakage. The hydraulic valve block can be replaced free of charge, but no one will bear the loss of those hydraulic cartridge valves that cannot be disassembled. After the boss learned that, he asked Kuplin to find a new manufacturer of hydraulic valve blocks. Kuplin contacted more than 10 new factories and required that there was no abnormality in the processing of valve holes of each hydraulic valve block. After a round, he did not find any suitable supplier of hydraulic valve blocks. Kuplin began to worry.

 

By chance, Kuplin met his old friend Petrov and learned about AAK's ability to process hydraulic valve blocks during the communicating with each other. After several communications with him, AAK started to make samples directly. 1 month later, AAK sent the hydraulic valve blocks. Petrov informed by email that their engineer specially inspected each valve hole, and the tolerance was controlled 100% without deviation. He wanted to know how AAK achieved it?

 

AAK hydraulic valve block has no deviation from the processing of the installation socket, is due to 3 strict points:

 

1. For tool inspection, it is in the charge of a specially assigned person, who regularly inspects each tool equipped in each machining center to confirm whether there are cuts or cracks on the leading edge of the tool, so as to avoid the problem of machining finish caused by tool wear or damage.

 

2. Clean the cutter. AAK uses a diamond file to remove the debris of the cutter material and ensure that the positioning shoulder on the reamer remains sharp. AAK will check the size of the ground tool based on the tool positioning shoulder to ensure that the depth and diameter meet the processing requirements.

 

3. After machining, use diameter gauge and thread gauge to check the dimensional accuracy according to the requirements of the socket drawing, and carry out the final socket dimensional check. Especially, the nose part of the cartridge valve socket will be measured from the front end of the nose to the supporting end of the nose, so as to ensure that there is no cone at the nose.

 

AAK hydraulic valve block is easy to install and take down without deviation, and 100% free of burrs. You are welcome to have a try!
