Systematic approach across all automation technologies
Machine tools equipped with automation solutions from Rexroth consume almost 50% less energy while still maintaining the same high level of productivity. The drive and control technology manufacturer consistently uses the Rexroth 4EE concepts to boost energy efficiency throughout the machine's service life — from the engineering stage to day-to-day operation. This significantly reduces operating costs and therefore costs per unit over the machine's entire useful life.
The strategy is based on energy-efficient components such as optimized servomotors and switch valves featuring an energy-saving mode. In addition, lightweight linear components such as the new slimline roller runner blocks reduce the total mass to be moved, thereby lowering the amount of drive power required. Rexroth offers machine manufacturers a comprehensive mechatronics support service to help them select and dimension the various automation components and identify potential areas for savings. The groundbreaking new IndraMotion MTX cta (cycle time analyzer) and MTX ega (energy analyzer) analysis tools allow the user to accurately record a machine tool's duration of movement and energy consumption online during operation. When integrated into Rexroth system solutions, these tools show NC programmers how they can save energy through optimized motion control, while still maintaining a short cycle time. Rexroth Service supports manufacturers in performing in-depth data analysis and can also assist with system optimization on request.
Consistently using Energy on Demand to regulate accessory drive requirements forms another cornerstone of the strategy. Rexroth Blue Hydraulic Drives, a scalable range of variable-speed pump drives, cut existing energy requirements for hydraulic systems by between 40 and 70 percent. The hydraulic modulators from Rexroth work together with the newly unveiled cooling lubricant booster to provide compressed air to the cooling lubricant system. This revolutionary new concept does away with the need for a second power train with its own energy requirements, leading to energy and cost savings while maintaining a high level of machine tool robustness. The new VT-ZBUS bus module uses innovative pulse width modulation to ensure demand-driven energy consumption on switch valves, thereby achieving energy savings of up to 66 percent and increased service life of the switch solenoids.
The modular IndraDrive drive controllers use carefully dimensioned DC buses to simplify the use of braking energy. Consistent use of the various Rexroth 4EE concepts yields energy savings of up to 45 percent on cutting machine tools, while maintaining the same high level of productivity.
