This study concerns the design of a head that is commonly identified as ‘universal’ for general mechanical processing.
Historically, the classic Universal Head is equipped with a mechanical tool spindle and two indexed and mechanically operated orientation axes; the power take-off is unique and is provided by the motor-spindle of the machine tool which it is installed on, generally a milling machine. This configuration requires the axes to be directed one at a time (with spindle rotation disabled) and inclinations must have approximate angle values due to the Hirth system used as indexing.
The purpose of this study is to create a newly designed Universal Head, equipped with an electric spindle and continuous and lockable orientation axes, actuated by direct drive motors.
This innovative configuration allows important advantages to be obtained: possibility of directing the two A and C axes simultaneously with evident gains in terms of time, possibility of directing the axes continuously without depending on indexing, possibility of working in interpolation on both axes and possible installation on machines with no motor-spindle.
The TCH 45 is a head that is designed to equip 5-axis machines for milling operations in the various fields of mechanics.
The TCH 45 expresses the best compromise between robustness and dynamics and therefore, it is suitable for 5-axis processing where both roughing and finishing of complex surfaces are required. Processing components for machine tools or structural aeronautical components are examples of its use.
