Hydraulic Cartridge Pressure Valves with 3 High Accuracy requirements, AAK solve

For a hydraulic cartridge pressure control valve with 3 high accuracy requirements, Jack spent 2 months on 3 cartridge valve manufacturers but the samples from all 3 factories failed. AAK completed the hydraulic cartridge pressure control valve with the main hole length diameter ratio of 10 in 25 days, and the main hole diameter tolerance is within 0.005mm, the cylindricity is 0.004mm, and the surface roughness is Ra 0.2μm.

Jack, from Melbourne, has been engaged in the procurement of hydraulic cartridge valves for nearly 3 years, with favorable wind and favorable water. Recently, he was trapped in troubles on the order of a hydraulic cartridge pressure control valve. His customer has strict requirements on the diameter tolerance, cylindricity and surface roughness of the main hole of the hydraulic cartridge pressure valve. He specially arranged 3 cartridge valve manufacturers to make samples at the same time. After 45 days, samples from only 1 of the 3 factories met the customer's requirements. However, in the first small batch order, the qualification rate of 120 hydraulic cartridge pressure valves was less than 60%. The customer requested to replenish the products, but the manufacturer had been prevaricating. Jack realized that he could only retain the customer by replacing the manufacturer of the hydraulic cartridge pressure valves.

Jack browsed the website of AAK hydraulic valves through B2B and found that AAK had produced hydraulic cartridge valves with high precision in cylindricity, roughness and aspect ratio. He felt that perhaps only AAK can help him. He directly emailed us the complete drawings of hydraulic cartridge pressure valves. After several rounds of communication, I suggested Jack directly order 60 hydraulic cartridge pressure valves, which can be completed in 25 days. Maybe the trust level hasn't arrived yet, I did not hear from Jack for a week and did not push him. A week later, he suddenly sent the PO of 60 hydraulic cartridge pressure valves.

Today, that is, 4 months after the 60 hydraulic cartridge pressure valves were shipped, Jack sent another PO for 300 hydraulic cartridge pressure valves of the same model. Jack's customers are very satisfied with AAK hydraulic cartridge pressure valves, and the 3 accuracies are all qualified. The diameter tolerance of the main hole of the hydraulic cartridge pressure valve is within 0.005mm, the cylindricity is 0.004mm, and the surface roughness is Ra0.2μm. The customer should quickly replenish the inventory and designate AAK for production.

AAK hydraulic cartridge pressure valve, meeting 3 precision standards, and is stable, because there are 3 guarantees in production:

1. Diamond reamers are used instead of conventional aluminum alloy reamers to avoid tool wear and effectively ensure the accuracy and quality of holes.

2. Set the best reamer parameters to ensure the form and position tolerance. The speed is 80-120 r/min, and the feed rate is 0.30 min/r.
