ABSTRACT:
A method for manufacturing a rotor, in particular for a power steering rotary valve, wherein a rotor is positioned in which a plurality of axial grooves have previously been designed. Tools are radially applied against the cylindrical surface portions separating two consecutive grooves of the rotor. The end surfaces of said tools has a shape adapted to match with said cylindrical surface portions when the tool comes into contact with the rotor. Each tool comprises protuding portions each forming a punch having a predetermined shape and adapted to realize chamfers in the adjacent edges of two consecutive grooves by repelling metal towards the bottom of said grooves. Radial penetration of said grooves is precisely determined, since it is limited upon contact of the tool cylindrical end surface with the corresponding cylindrical surface portion of the rotor.
