CNC Machine Energy Efficiency: How Much Can You Realistically Save

Machine Tool Energy Efficiency: How Much Can You Really Save

Rising electricity tariffs and power capacity limits are forcing manufacturers to scrutinize every kilowatt. Modern metalworking equipment responds to this challenge not with slogans, but with concrete engineering solutions — from variable frequency drives to the full replacement of hydraulics with electric servo systems.

A clear example is the CoastOne CONE C9 electromechanical press brake: switching to an electric servo drive instead of traditional hydraulics cuts cycle time by roughly 30%, while electricity is consumed only during the actual bending phase. According to the manufacturer, running one shift per day, this delivers savings of up to 3,000 kWh per year compared to a hydraulic equivalent.

Similar solutions — frequency converters, "smart" standby modes, servo drives — are now being implemented across a wide range of equipment, from presses to lathes and band saws.

A detailed breakdown of energy-saving technologies, with real examples from our catalog, is coming soon in a new article on the MACHENTECH blog.
