AAK can deliver 500 pcs of hydraulic directional control valves PC08-30 within 30 days, due to higher efficiency unmanned operation

China [CN]

Snova is from Russia. A few days ago, she left a message on AAK hydraulic valve website:

1．Can AAK deliver 500 pcs of hydraulic directional control valves PC08-30 within 35 days?

2. The outer diameter accuracy of the valve cage needs to be higher than HydraForce standard, as our original system has a higher accuracy setting than HydraForce.

3. Can we ship first and make payment later?

Upon seeing this message, I estimated that she encountered difficulties in purchasing the hydraulic directional control valve PC08-30. After communication, I learned that she had chosen a hydraulic cartridge valve manufacturer in Ningbo China. In fact, the manufacturing quality of this manufacturer should not be a problem compared to that of HydraForce PC08-30. Snova advised that the main issue is the unstable accuracy of the outer diameter of the valve cage, as their standard is higher than that of HydraForce PC08-30. Based on the 3 points in her message, I replied that point 1 and 2 are a challenge, but we are confident in surprising her. Point 3 is impossible, AAK never does credit business.

Snova mentioned that because the original hydraulic cartridge valve manufacturer wasted 6 weeks, she must find a manufacturer who is able to deliver 500 pcs of hydraulic directional control valves PC08-30 within 35 days, and the outer diameter accuracy of the valve cage needs to be higher than HydraForce PC08-30 standard. The valve cage that happens to be being processed in AAK workshop is somewhat similar to PC08-30. I sent her a video to show the production process. Whether it is precision control or production efficiency, this video can dispel Snova's concerns.

For precision machining of the outer diameter of the hydraulic directional control valve cage, especially the precision requirements in 1-2μm, it can be done by using Japan's Tsugami CNC centerless grinding machine. The biggest advantage of this equipment is the grinding wheel shaft, which uses Tsugami's high rigidity dynamic pressure bearings, without any possibility of deviation, providing guarantee for accuracy without deviation. Before the production of the hydraulic directional control valve cage, according to the accuracy requirements of the valve cage, set the system program, adjust the height of the workbench, ensure that the installation position of the workbench, valve cage, and the distance and angle between the spindle axis meet the requirements, which tests the skills of the technician. AAK has also equipped the device with an automatic turntable. We only need to place the valve cage to be processed into the turntable. After starting the device, there is no need for technicians. The centerless grinding and precision machining does not need manual labor, with an efficiency increase of over 30% and an accuracy 1μm higher than HydraForce FC08-30. 

30 days later, last week, AAK delivered 500 pcs of hydraulic directional control valves PC08-30. Snova is very happy, at least AAK's production efficiency is higher than other hydraulic cartridge valve manufacturers in Ningbo China. I told her that there was no need to worry about the outer diameter accuracy of the valve cage, as AAK's standard was 1μm higher than the HydraForce standard. 

AAK hydraulic directional control valve, with an efficiency increase of over 30% and an accuracy increase of 1μm, you can also give it a try!
