The original manufacturer was unable to meet the valve hole requirement for the hydraulic valve block, and Caltha returned to AAK 2 months later

China [CN]

Caltha is from Mexico and has been purchasing hydraulic valve blocks in Ningbo China for 5 years. AAK is also one of his suppliers of hydraulic valve blocks. At the beginning of this year, their old buyer left the company and Caltha began to be responsible for the procurement of hydraulic valve blocks. The first inquiry I received from Caltha was for hydraulic valve blocks. A week later, Caltha informed AAK that the price was 17% higher and she chose another hydraulic valve block manufacturer in China. Upon seeing this big price difference, I had to give up.

2 months later, Caltha emailed me asking if the hydraulic valve blocks quoted at the beginning of the year could be completed for 5 samples within 25 days. I felt Caltha's anxiety, and after communication, I learned that the hole accuracy of the hydraulic valve block produced by the original manufacturer was not up to standard. However, the manufacturer blamed some valve hole accuracy deviations on being normal, and using electric sealant could solve the leakage. Caltha didn't want to take any risks and came back to AAK

I can understand Caltha's emotions, after all, their company is a loyal customer of AAK. Our technical team started to decompose the hydraulic valve block drawings immediately. Within 25 days, AAK sent 5 hydraulic valve block samples. 

2 weeks later, Caltha informed AAK that their hydraulic manifold had been tested successfully. She asked me to wait for the batch order of hydraulic valve blocks. The processing of hydraulic valve block valve holes that the original manufacturer cannot handle mainly depends on the selection of equipment and the control of accuracy.

The processing of this AAK hydraulic valve block adopts the Taikan Group Processing Center, which has 3 major advantages:

1. The machining is stable, and its spindle structure adopts high-quality mihanna cast iron, with stable movement. For the same batch of hydraulic valve blocks, using the same tool and processing program, the motion trajectory of the tool is the same, and its CNC program achieves computer control, which can avoid human error. Most hydraulic valve block manufacturers do not choose this equipment.

2. High precision. The valve hole accuracy is within 0.005mm, and the repeated positioning accuracy can reach 0.003mm, and precision correction and compensation can be carried out simultaneously using CNC software.

3. High production efficiency. The spindle speed can reach 24000 RPM, and it also has functions such as automatic speed change, automatic tool change, and other auxiliary operation automation. Compared to ordinary machine tools, the production efficiency is 3-4 times higher.

AAK hydraulic valve block, fast processing, and guaranteed accuracy, you can also give it a try!
