How to reduce the cost of processing single hole by 70% and increase the production efficiency by 10 times with finishing reamer processing in engineering hydraulic valve block？

Hydraulic control valve is a very important component in the construction machinery industry.

Its function is to control and adjust the flow direction, pressure and flow of hydraulic oil in the hydraulic system, so that the actuator and its driven working mechanism can obtain the required movement direction, thrust(torque) and movement speed (rotation) etc. No matter the structure is simple and complex, any hydraulic system can not lack of hydraulic (control) valve.

There are many holes need to be finishing reamed in the hydraulic valve block of the hydraulic control valve, it is a difficulty to process these holes with high efficiency and quality in the cutting tools industry, especially some finishing reamer of deep holes.

The traditional carbide reamers usually can achieve about Ra1.6 roughness in finishing reaming for hydraulic (control) valve, the linear velocity is generally not higher than 50m/min, tool processing life is usually less than 300 pieces. For this situation, Shanghai Nagoya’s technology R&D team has designed and developed a high-speed machining scheme in brazed reamers of special flute and cutting edge with patent protection after repeated verification and trial cutting.

Compared with the traditional carbide reamer, the brazed reamer developed by Shanghai Nagoya can produce the parts with surface roughness less than Ra0.5, and has a huge improvement in processing efficiency and tool life.

Up to now, the brazed reamers of shanghai Nagoya has popularized and used in many well-known customers and end-user, which has solved the technical difficulty of finishing reaming hydraulic valve blocks in the construction machinery industry.
