AAK hydraulic valve block, from a five axis CNC machining center, is milled with a thread milling cutter, completely replacing the traditional radial drilling machine processed with a formed tap, and the thread surface roughness value is Ra1.6μm. The traditional Ra is at 12.5μm. Ra alone has increased sevenfold. Archie purchased AAK hydraulic valve blocks, which not only stopped losing more than 30,000 dollars, but also made an additional profit of more than 10%.

 

For the hydraulic valve block with conical pipe thread, the pipe thread cannot completely seal oil, which is an industry problem. The vast majority of hydraulic valve block manufacturers use traditional radial drilling machines and formed taps for processing. The surface roughness of their threads is a "mine", especially the processing of offset holes, which is a hot potato.

 

Archie, from Australia, purchased most of his hydraulic valve blocks from India, but these hydraulic valve block manufacturers use radial drilling machines for processing. Archie did not know that this traditional process cannot afford to process tapered pipe threads. The order of more than 30,000 dollars in his hand had been involved for 4 months, but the sample of the hydraulic valve block had not passed the standard. The customer was not satisfied. Archie wanted to give up the order, but he was very depressed because of his high profit and unwilling to lose the customer.

 

Archie occasionally noticed many customer cases of AAK hydraulic valve blocks through B2B. He sent an email to ask if it is possible to produce a special hydraulic valve block for him. After AAK technical team refined the drawings, the whole processing process was implemented and had a foundation. I told him that the bottom diameter of the oil hole and valve hole of this hydraulic valve block is large, and most of them are offset holes. At the same time, the taper pipe thread of the oil hole is large, and the oil pressure under working conditions is large, so if accuracy can not be guaranteed, all efforts will be wasted. Archie may realize that when come to the point, and asked us to make samples.

 

After 25 days, 5 hydraulic valve block samples were sent out. 3 weeks later, Archie informed us that the customer had approved the manufacturing quality of AAK hydraulic valve blocks, and that there was no tooth breakage on the thread, especially the thread surface roughness value is Ra1.6μm, the customer was amazed, and the whole sealing performance of the hydraulic valve block was also recognized after the pressure test. 6 years ago, AAK hydraulic valve block was processed with a five axis CNC machining center, instead of the traditional radial drilling machine. A thread milling cutter is used to program for milling. At the same time, according to the pipe thread size, the spiral interpolation milling can obtain stable thread quality, and the thread surface roughness can reach Ra1.6μm. The hidden trouble that the pipe thread cannot seal oil is completely solved.

 

A few days ago, Archie told me privately that AAK hydraulic valve blocks not only saved the customer for him, but also increased his extra profit by more than 10%. The boss was very happy and his authority was also great.

 

AAK hydraulic valve blocks, good at high precision, you are welcome to have a small try!
