For the Hydraulic Flow Control Valve that more than 20 manufacturers failed to produce, AAK optimize

Peter is from Australia. One of his old customers wanted to purchase a special hydraulic flow control valve. Peter realized that the valve hole of this hydraulic flow control valve has high accuracy and is difficult to process. If the surface roughness and cylindricity error cannot be well controlled, it is easy to cause the valve spool to be stuck.

Peter accidentally found AAK hydraulic valves. I told him that most hydraulic valve manufacturers still use traditional processing methods to process the valve hole of this hydraulic flow control valve. According to the requirements of the drawing parameters, they also know that the surface roughness is a threshold. For example, the abrasive particles are easy to be embedded in the workpiece surface, and the cutting is not easy to be separated from the grinding oil, resulting in poor cleanliness of the grinding oil. All these affect the surface roughness.
