AAK Hydraulic Relief Valve, Valve Element with Inclined Hole

Janice, from Canada, wants to purchase 600 hydraulic relief valves. The core
difficulty of this hydraulic relief valve lies in the processing of valve
elements. Most factories can only bemoan their inadequacy for the valve
elements with inclined holes and included angles. The American hydraulic relief
valve manufacturer who has been cooperating with Janice has failed 4 times in
30 days and had to surrender. Janice found more than 20 hydraulic relief valve
manufacturers online and offline, at home and abroad, but they either replied
that there was no time for sampling or no response. Janice has been tossing
about for a week and is a little frustrated.

Pablo, an old customer of AAK, after learning about Janice's procurement
problems, suggested that she send the hydraulic relief valve drawing to AAK for
a try. Pablo also specially wrote me an email to ask AAK to help Janice. I am
willing to try to solve such a difficult problem of hydraulic relief valve.
Once it is solved, I have won the admiration of two people at the same time.

According to the hydraulic relief valve drawing sent by Janice, except for the
valve core, other requirements are also conventional. The valve core of this
hydraulic relief valve is different from the conventional straight hole valve
core, which is marked in the drawing Φ4- Φ3.7mm inclined hole, and the axis
line of the Φ3.7mm hole forms an included angle of 60 ° with the axis of the
valve core parts. It is difficult and requires high precision in the clamping
and positioning process of hole processing. The hydraulic relief valve
manufacturers without high-precision equipment and over 15 years old
technicians will fail even if they try to make samples for 100 times.

AAK technical team discussed for 2 days, and they were 70% confident that the
sample would be successful. Although Janice is a little disappointed, it is
also the best news she has received recently. She is in urgent need of this
hydraulic relief valve. AAK has been brainstorming for 2 weeks, constantly
changing the material of the hydraulic relief valve core, adjusting the process
parameters, and sending the hydraulic relief valve sample for the first time.
After 5 days, Janice informed that there was an error of 0.1% in the inclined
hole of the hydraulic relief valve spool. AAK carried out the second hydraulic
relief valve sample and optimized the process again on the high-precision
turning milling composite locomotive to improve the accuracy of the inclined
hole. A few days after AAK's second hydraulic relief valve sample was sent,
Janice sent an e-mail. The American manufacturer spent 4 weeks on this
hydraulic relief valve, but all 4 samples failed. She tossed and turned for a
week and failed to find a hydraulic relief valve manufacturer that dared to
make samples. However, AAK succeeded in 2 proofing within 2 - 3 weeks.

AAK high-precision turning milling compound machine tool is the core of the
success of the sample. This machine tool is equipped with upper and lower tool
towers. The main shaft can be 360 ° indexed. The upper shaft is the milling
main shaft, with a rotation angle of 225° and 40 tools. At the same time, it
can complete the machining of axial hole, radial hole, inclined hole drilling
and reaming, inclined groove and tapping under one-time clamping. The key to
the success of AAK sample is our old technician, who has 32 years of practical
operation experience. With specially assigned person and special machine, AAK
has unique skills in turning and milling compound machine tools.

AAK hydraulic relief valve, valve element with inclined hole and included angle
can also be produced. You can also have a small try!
