Efficient use of energy
For years, INDEX has viewed the efficient use of energy and resources as a key requirement in its machine development activities. Therefore, today all Machines already conform to the principle of reduced energy consumption with simultaneous improvement in environmental compatibility. Design experience, such as measurements on machines in the field, form the basis for meeting or even surpassing requirements regarding energy/resource efficiency sustainably, including in the future. Weight reduction: • Reduction of energy consumption Simulation programs enable minimization of weights of moving assemblies, while simultaneously optimizing stiffness and damping of machines. Assemblies with reduced weights consume significantly less energy during braking and acceleration. • Increased dynamic response Standard available motor designs and frame sizes are sufficient for achieving above-average high acceleration, braking, and rapid traverse rates at reduced weights. Smaller Motors consume less energy and also exhibit less energy losses. Minimized friction: • Optimum material pairings Optimized material pairings and surface coatings reduce the coefficient of friction and, thus, the energy consumption of moving Components. • Low-friction bearings The hydrostatic bearings used on the tool carrier quills are practically free of friction. This minimizes friction heat and energy losses; in addition, these bearings are practically wear-free. Energy recovery/ energy shutdown: • Energy recovery Regenerative drives of the turning/Milling center transform the motion energy of all braking operations on spindles and axis drives directly into electrical energy and feed it back to the supply network. This reduces energy consumption on a sustainable basis and reduces the heat emission in the proximity of the machine. • Energy shutdown The R200 has an automatic shutdown function that automatically shuts down all high energy-consuming units after a user-defined time elapses following an unplanned production interruption (standby mode). Intelligent use of proven cooling principles: • Targeted heat dissipation All high-loss heat sources of the R200 are cooled directly with different cooling media via multiple fluid circuits. In addition to the cooling circuits for the main spindle, counter spindle, and milling spindles, the Hydraulic system and control cabinet also have a separate cooling circuit. The lost heat energy is absorbed directly in the fluid and conducted from the machine from a central location. • Economic use of waste heat The INDEX “cold water interface“ allows the heat loss energy stored in the cooling medium to be removed from a central location and conveyed for another use, if required, e.g., production hall heating service water heating, or process heating for other production steps. The recovery of machine waste heat enables a sustainable reduction of energy costs in the company. • Climate-neutral dissipation of heat The cold water interface provides the ability to dissipate heat in a climateneutral manner, if the machine waste heat stored in the cooling medium cannot be used otherwise. The necessary cooling unit can, with the aid of the water interface, be used outside the production hall as well as centrally across several machines. This offers considerable potential energy savings for the production hall cooling/climate control and/or increased efficiency as a result of centralized heat disposal.
