This particular blades locking shows a helical form; Meccanica Precisa has realized it for the automatic machineries industry of paper processing.
The function of the component is that of blocking a blade on a roll, called punching machine, in order to make the paper tears carving the same paper.
The precision level of the manufacturing is decimal.
For the realization of the helical blocking, made through automatic milling, they have used the following machine tools and equipment:
The component is realized in C45 with surface phosphating treatment, in order to improve the resistance of the material to the corrosion.
