Abstract
When cutting metal rods, for instance, percussion machines are used that utilize stored kinetic energy which has been produced either mechanically or by the use of compressed gas. A drawback is the inability to accurately control the cutting process. The present invention makes use of hydraulics to control the process, thereby achieving total control of the course of the function.
