AAK Hydraulic Cartridge Valve Cage High Accuracy Surface Finish Grinding

Recently, an IP from Germany left a message on the website of hydraulic cartridge valve manufacturer AAK: Can AAK process a hydraulic cartridge valve with the surface finish of the valve cage controlled within Ra0.2μm and with a dimensional accuracy tolerance within 0.5μm? I was a little pleasantly surprised to see this message because:

1. There are not many inquiries from German customers regarding hydraulic cartridge valves, although hydraulic cartridge valve manufacturer AAK has supplied more than 30 countries, this should be the third German customer's inquiry.

2. Not many customers seem to have special requirements for the surface finish of hydraulic cartridge valve cage.

After 3 rounds of communication, I learned that Frank is a procurement engineer for hydraulic equipment company.
