Our hydraulic valve customer Pablo from the Netherlands has an order for hydraulic relief valves. Although the order qty is only 800, it requires very high precision of grooves. He asked me for a quotation at the first time, but he thought that the quotation of AAK hydraulic relief valve was 20% higher. I also agreed with him to check with the price other hydraulic relief valve manufacturers. Pablo consulted all the hydraulic valve suppliers on hand, and most of them said that they could not achieve the groove accuracy of the hydraulic relief valve drawing. Only 2 factories could have a try, but the price was at least 60% higher than that of the conventional hydraulic relief valves. Moreover, only after the sample was made, they could know whether the groove accuracy could meet the standard. Pablo was a little confused. After wasting a week, he returned to AAK Hydraulic Valve.

 

Pablo was surprised that most manufacturers could not do the groove precision of hydraulic relief valve, which seemed to be a very conventional process. I told him that the cutting and processing area of this hydraulic relief valve was closed, with high resistance of the cutting tools, fast wear and tear, and difficult chip removal. The groove precision was even more difficult to ensure, that is, the conventional processing technology was not feasible, which was also the reason why so many hydraulic relief valve manufacturers gave up. At the same time, I told him that the two hydraulic relief valve manufacturers who were willing to try were 60% more expensive because they used high-speed milling to avoid tool damage and improve groove accuracy. This technology is not only costly, but also has very strict requirements for the entire processing system. Otherwise, the accuracy cannot be guaranteed, and most manufacturers cannot control this technology.

 

Pablo was surprised by our understanding of the industry. It seems that he can only choose AAK to make the samples. Two weeks later, we successfully sent 6 samples of hydraulic relief valve. Their engineers approved AAK hydraulic relief valve samples at one time after receiving them. I fed back to Pablo that AAK adopted UG CAD module to solve this processing problem. No hydraulic relief valve manufacturer in Ningbo would think of using this technology.

 

This technical point is imported from Germany. The CAD module of UG is used to model the geometric parameters of the groove, and then the CAM module of UG is used to NC program the machining of the groove of the hydraulic relief valve. The tool path and cutting method are set by programming. The NC program thus obtained can carry out the precise machining of the groove and solve the problem of chip removal. The reason why AAK can effectively deal with the high-precision machining of hydraulic relief valve groove is that after generating the tool path of machined parts, the whole process is simulated by using the simulation function of UG software. Our technicians can clearly see the processing path of the processing tool, that is, turn the closed area into a visible area. After the simulation, determine the tool direction through UG software, and then import it into the file of the NC machine tool to generate the code for executing the command.

 

AAK hydraulic relief valve groove processing adopts simulation modeling technology, which not only reduces the cost, but also ensures the accuracy. You are welcome to try the order.
