DMG MORI CO., LTD. (hereafter referred to as DMG MORI) has developed “Adaptive Coolant Flow,” a new solution that automatically optimizes high-pressure coolant flow during machining. The function reduces excessive coolant usage while maintaining machining performance, contributing to lower energy consumption, reduced CO₂ emissions, and progress in Green Transformation (GX).

Rising global energy prices in recent years have led to increasing electricity costs in manufacturing, making sustainable production systems more important than ever. While DMG MORI already provides energy-saving functions such as “GREEN MODE,” peripheral equipment like coolant systems still account for a considerable share of total energy consumption. Precise coolant flow control therefore enables direct reductions in both operating costs and environmental impact.

Adaptive Coolant Flow automatically optimizes highpressure coolant flow according to the cutting tool. The system consists of two elements: software that calculates and regulates the optimal flow rate, and a control unit on the coolant tank. Conventional systems discharge coolant at maximum pressure by default, causing unnecessary coolant and energy loss.

In comparison, Adaptive Coolant Flow reduces the energy consumption of high-pressure pumps by over 80 %^*1 while maintaining tool life and surface quality. Its complex high-pressure piping components, which cannot be machined with traditional cutting equipment, are realized with additive manufacturing on DMG MORI’s LASERTEC 30 SLM. The compact design enables efficient pressure and flow control integrated directly onto the coolant tank. Built-in sensors monitor flow rate, pressure, concentration, and temperature, with all data displayed in real time on ERGOline X with CELOS X.

Beyond reducing energy costs and CO₂ emissions, Adaptive Coolant Flow also minimizes mist generation and coolant evaporation in the machining area, significantly decreasing total coolant consumption. This results in fewer refills, higher operability, and stable automated production, particularly during unmanned nighttime and weekend operation.

DMG MORI will continue to address customer needs with highly functional and reliable products that deliver longterm value.
