Fuel regulator shell parts are the key components in aero-engine hydraulic products

characterized by numerous pore sizes

small aperture

large depth-diameter ratio

and so on. Considering the problems of a long processing cycle

a large number of cutting tools utilization

low efficiency

and high cost in the complex and high-precision hole machining of the fuel regulator shell

the personalized internal type composite forming cutting tools are designed and manufactured based on the structural characteristics and accuracy requirements of the hole. By improving the process plan and optimizing the cutting parameters and fulfilling the practical application in the product

the steady machining of the complex and high-precision hole can be efficiently achieved with high quality
