Multi-spindle drilling machines HMDD

Horizontal multi-spindle drilling machines HMDD are used in the energy and chemical industries for deep drilling in sheets and baffles for heat exchangers.
 
In the standard configuration, the machine is equipped with 3 horizontal spindles providing the highest smoothness of the surface of the holes made. The possibility of personalization ensures that the equipment and parameters are adapted to your technological requirements.
