Hydraulic Cartridge Valve Spool Upgraded Automatic Processing - China

price: 30.00 Dollar US$

Due to the presence of an operator, Frank rejected AAK hydraulic cartridge flow control valve, but I am happier now Last week, the video I sent to Frank about how hydraulic cartridge valve manufacturer AAK processes the valve spool of hydraulic cartridge flow control valves using a centerless grinder was not approved by him, which made me very disappointed and also helped me understand the requirements of German customers for automated production.

Frank from Germany needs to develop a hydraulic flow control valve, but there is a requirement for the accuracy of the valve spool, which requires centerless grinding equipment for precision machining.

Frank learned that hydraulic cartridge valve manufacturer AAK has this equipment, so he asked me to take a video of the work for his reference.

The next day, Frank said, "Why does it still need a person to assist in completing it?"? I realized that Frank rejected the hydraulic cartridge valve manufacturer AAK because of this.

But I'm not too worried, because the automated production process is a strong point of hydraulic cartridge valve manufacturer AAK.

Although there is no chance for the hydraulic flow control valve this time, Frank, a customer who is meticulous, will definitely return to AAK.

3 days later, I said to Frank, ‘thank you for your reminder.

The mechanical arm plan for automatic material retrieval and feeding equipped for the centerless grinder is already in place.

It is expected that in 3 months, I will provide a video of the fully automatic centerless grinder processing the hydraulic flow control valve spool.

At the same time, I will also send you some previously unmanned fully automatic processing processes’.

Let's go back to last week's video to Frank that using a centerless grinder to process the spool of a hydraulic flow control valve.

This CNC centerless grinder is equipped with an automatic conveyor belt.

The operator only needs to place the rough machined valve spool on the conveyor belt, and the valve spool is sequentially fed into the grinding area.

After one machining is completed, it is automatically placed in the next one.

The grinding wheel adopts diamond grinding wheel, which provides a basis for the stable accuracy of the valve spool due to its hardness and wear resistance.

The control system of the centerless grinder is stable, with no faults during long-term processing, and the stability of grinding provides assurance for the accuracy and stability of the valve spool.

Thanks to Frank's advice again.

In fact, the more requirements customers have for you, the more they hope you will grow until you meet the qualifications of their preferred supplier.

I like this type of customers.
