Machine tools and working systems

Abstract

This invention provides a technology that enables the reuse of regenerated energy from peripheral machines employing resistance regeneration to work machinery, thereby achieving overall system power saving. The work machinery (10) includes: a CNC (Computer Numerical Control) device (105); an amplifier (103) that drives a motor (104); a power system (102) that supplies power to the amplifier (103) to drive the motor (104); and a voltage converter (106) that matches the voltage of the regenerated power from the inverter (201) of the peripheral machine (20) that drives the auxiliary work machinery (10) to the voltage of the power system (102). none
