The intelligently polished AAK hydraulic valve block is 100% burr free

Last Wednesday, there was a repeat order from Peppe for a hydraulic valve block, which was tested in the second half of last year. Peppe required that the repeat order quality should be 100% burr free as same as the hydraulic valve block tested samples last year. Peppe comes from a hydraulic equipment company in Italy. At the beginning of last year, the paper cutter equipment they sold would stop automatically and was complained by customers. It was found that the hydraulic relief valve was stuck on the site, and the after-sales servicer thought that there was a problem with the hydraulic relief valve. After the original hydraulic valve block manufacturer disassembled it, it was found that there were debris at the moving part of the valve spool. At the same time, foreign matters were also found in the hydraulic oil, so it was known that it was caused by the incomplete burr cleaning of the hydraulic valve block.

The original hydraulic valve block manufacturer also does not deny it. The burr cleaning of the inner cavity of the oil channel, the cross hole and the blind hole of this hydraulic valve block was indeed less than 100%. As long as the hydraulic oil can be replaced every 3 months, the problem can be solved. Peppe was very speechless and had to find a new hydraulic valve block manufacturer, and deliberately required 100% burr free. She contacted more than 10 hydraulic valve block manufacturers, they either gave no reply or could only have a try, but Peppe didn\'t have time to test, and began to worry.

Peppe noticed the introduction of \"100% burr free hydraulic valve block\" in AAK on Google, so she directly sent us an email. I told her, \"according to your hydraulic valve block drawing, there are many inner cavities and cross holes in the oil duct, especially the burr cleaning at the blind hole is a difficult problem. The traditional abrasive flow deburring method to remove this hydraulic valve block has hidden dangers. AAK suffered from it 5 years ago, and it was not until we used the new deburring technology that we dared to ensure 100% burr free\". Peppe asked us to make samples as soon as possible. A month later, AAK sent 5 hydraulic valve blocks.

6 months later, Peppe emailed us that the paper cutter installed with AAK hydraulic valve block has been working normally. I told her that AAK adopted an intelligent grinding processing system to replace the traditional abrasive flow process. If this hydraulic valve block is deburred with abrasive flow, and the blind hole is easy to form a dead corner. The intelligent grinding and processing system can realize automatic solution. In the grinding process of the hydraulic valve block, with continuous power support and stability, the main shaft of the equipment can swing 360 °, which can realize the grinding of any angle and any inclined plane. No matter in the fixture positioning, or in the automatic optimization compensation of the simulation path simulation of the hydraulic valve block structure, the intelligent grinding processing system has no dead corner. No matter the surface of the hydraulic valve body, or the inner hole, cross hole, blind hole of the hydraulic valve block, as well as the end face and inner and outer contour of the orifice, the burrs can be completely removed.

AAK hydraulic valve block, no burr, you can also have a small try!
