The valve lifter for thermal propulsion engines is a component realized in the precision factory Meccanica Precisa for the automotive industry.
They have made the manufacturing with a precision centesimal level through the milling process and the help of the CAD CAM software for the 3D design and the machinery placement.
The component does an oscillating movement during which it hooks the valve, and then to reposition it at the piston passage.
The machine tools used for the realization are:
They have realized the valve lifter in steel through a thermal treatment of quenching and cementation, in order to increase the hardness of the material and to make it more resistant to wear.
