Like stamping presses, servo-controlled CNC punching machines deliver benefits of both mechanical and hydraulic units, and much more. From the venerable mechanically driven workhorses that still dot fabrication shops to hydraulic units enabling position control of the rams, punching machines have proven their worth over decades. In the early '90s, the entrance of servo drives fostered another revolution in CNC punching machines. Since then, servo-controlled rams have provided the heart of these machines, benefitting from ever-increasing performance and reliability of servo motors and the capabilities of the machines' control and software brains.
