The Hydraulic Cartridge Flow Control Valve Failed In 3 Proofs With Old Supplier - China
price: 100.00 Dollar US$
The supplier who has cooperated for 3 years has failed to test the hydraulic cartridge flow control valve for 3 times.
After AAK took over, the accuracy requirements were met at one time for the sample.
The surface roughness of the inner hole of the hydraulic cartridge flow control valve was 0.15, and the cylindricity error was controlled within Φ0.003mm, the operating efficiency of the hydraulic system was also improved from 5% to 10%.
Brand finally came to the sunny day from the rainy day for more than 30 days.
Brand is from Brazil.
In March this year, he sent me an inquiry for customized high-precision hydraulic cartridge flow control valve.
The surface roughness of the inner hole is Ra0.2, and the cylindricity is Φ 0.003mm.
Compared with the conventional hydraulic cartridge flow control valve, the precision is improved by nearly 10%.
The cylindricity and the surface roughness of the inner hole are the core of the valve hole precision.
There are no more than 5 hydraulic cartridge valve manufacturers in Ningbo that can successfully sample at one time.
Seven days later, Brand told AAK that the price was 20% higher than that of the other hydraulic valve manufacturers.
With such a large difference, I knew that there was no comparability.
The price and hydraulic cartridge flow control valve were visible, but the manufacturing quality was invisible.
40 days later, Brand asked by email how long it would take to sample the hydraulic cartridge flow control valve quoted last time.
I was a little surprised.
After communication, we learned that the he chose the manufacturer who has cooperated with them for 3 years to make samples for this high precision hydraulic cartridge flow control valve, but proofing failed for 3 times.
There was still a 5% discrepancy on the surface roughness and cylindricity of the inner hole of the hydraulic cartridge flow control valve, which could not be achieved all the time.
Their engineer blamed brand for poor procurement, and the boss was also unhappy with him.
I told him that an American customer of AAK encountered similar problem a month ago, AAK solved it for him.
When Brand learned of our successful case, he saw hope and was relieved.
After 20 days, the samples of hydraulic cartridge flow control valve were sent successfully 2 weeks later, Brand informed that the surface roughness and cylindricity of the inner hole of the AAK hydraulic cartridge flow control valve and the accuracy parameters not only met the standard, but also improved by more than 10% compared with their original requirements.
What's more surprising is that the overall operating efficiency of the system was also improved from 5% to 10% when the AAK hydraulic cartridge flow control valve was installed, which surprised their engineers.
We were also complained about the surface roughness and cylindricity of the inner hole 5 years ago.
Now AAK uses rolling technology to replace the traditional cutting method, uses rollers to roll the metal surface, flatten the convex part of the surface, and make the concave part bulge, and then process it into a smooth surface like mirror.
The details of rolling technology need skills.
The surface roughness of the valve hole processed by an old experienced craftsman will be nearly 1% higher than that of grinding, which is why we can reach Ra 0.15, and the cylindricity error is controlled within 0.003 - After the working face is hardened, the wear resistance and fatigue strength are increased, which is also the advantage and feature of this process, but it requires experience to master it skillfully.
