Aak Used Imported Tools To Solve The Problem Of Rough Inner Hole For Hydraulic Relief Valve - China
price: 100.00 Dollar US$
Half a year ago, David, an American customer, sent an inquiry to AAK about 500 pilot operated hydraulic relief valves.
This hydraulic relief valve is difficult to process the inner hole.
Our cost accounting department gave a reasonable price.
3 days later, David informed AAK that the price of the hydraulic relief valve was 16% higher than that of other manufacturers and he could only place the order with other hydraulic relief valve manufacturer.
As far as I know, there are not many manufacturers who can make this hydraulic relief valve.
The price provided by AAK this time should be very cost-effective.
As David is our old customer, we never quote prices indiscriminately.
I always believe that it is also a sign of dishonesty to quote prices indiscriminately.
Last month, David asked again whether the hydraulic relief valve quoted last year could maintain its original price.
I asked him curiously, hasn't this hydraulic relief valve placed an order yet? David truthfully told us that last time, the pilot operated hydraulic relief valves purchased in another manufacturer were reported by the users that the stability was poor and the valve was often stuck.
They decided to get replacements.
David contacted the original manufacturer of the hydraulic relief valves, but the manufacturer was unwilling to offer replacements.
Because there were too many complaints, David did not dare to ask the original manufacturer to re produce, so he emailed AAK.
David was very cautious this time.
He specially sent us 5 samples of hydraulic relief valves from the original manufacturer.
After receiving and checking, we found that the inner hole of the hydraulic relief valve has a taper, the processing size is not accurate, and the surface roughness Ra is as high as 1.6μm.
The root cause of these problems is that the processing tool rotates improperly, which also shows that the original manufacturer is not good at processing this special inner hole.
No wonder there are so many complaints.
It is wise for David to change the factory.
David was satisfied with our diagnosis of this hydraulic relief valve and asked us to make samples as soon as possible.
1 week later, AAK sent the samples of hydraulic relief valve, and David approved our samples at one time.
They specially compared AAK hydraulic relief valves with that of the original manufacturer.
Their engineers admired the inner hole processing of AAK, which not only has no taper, but also has more than twice the accuracy of the original manufacturer.
For the special inner hole of this pilot hydraulic relief valve, AAK adopts CBN cubic boron nitride cutter from Sumitomo company of Japan to replace the conventional ceramic cutter.
Most hydraulic relief valve manufacturers dare not use this cutter, which is not only costly, but also exquisite in operation.
After the program is set, the tool completely avoids the taper of the inner hole.
At the same time, for the machining of inner holes, we also customized the CBN boring cutter of integral cemented carbide steel, which can ensure the roughness value Ra below 0.8μm.
Our technicians deliberately adjusted the cutting parameters to: n=400r/min, f=0.08mm/r, which improved the production efficiency and dimensional stability.
AAK has never been stingy with the cost to ensure the processing quality.
For the inner hole processing with high quality, AAK only uses the latest and most efficient cutting tools in the industry.
AAK hydraulic relief valves most welcome customers with high quality.
You are welcome to give it a try and be repaid with AAK unique skills.
