Whether in spindle cooling or in other areas of application - HYFRA's innovative functions repeatedly ensure that customers benefit greatly from its chillers. For example, units with FleXX technology flexibly adapt the operation of components such as the fan, compressor and expansion valve to the requirements of the respective application. This form of cooling reduces energy costs by up to 30% and at the same time leads to significant savings in refrigerant. In addition, FleXX technology achieves particularly high temperature accuracies of up to 0.1 K. The state-of-the-art plate heat exchangers in the current HYFRA Sigma series of cooling water recirculating chillers also operate particularly efficiently. They are also lighter and take up less space than conventional heat exchangers.
When selecting the right cooler, HYFRA works closely with the experts on the customer side. This intensive exchange ensures that the cooling system is precisely matched to the customer's requirements. On request, for example in the case of special on-site conditions, HYFRA engineers can also develop and design a completely individual cooling solution. From planning to acceptance, the customer receives all services from a single source. This facilitates the smooth running of the project, so that the plant is ready for operation after a short time. If the operating conditions of a chiller change fundamentally at the customer's site, HYFRA also adapts the unit specifically to the new requirements with modification kits.
Which machine tools use water cooling?
Water-based cooling is basically suitable for many different machine tools. It cools reliably over a wide speed range, including high speeds. Thus, water-cooled spindles are used for milling as well as for turning, grinding and many other operations. For various requirements, spindle manufacturers offer both modern motor spindles and spindles with belts in a water-cooled design.
How is the machine tool spindle supplied with cooling water?
Just like the required cooling capacity, the routing of the cooling water in the spindle also depends on the spindle model and the associated machine. As a rule, the coolant enters the spindle housing via a nozzle. Depending on the model, HYFRA chillers supply the coolant at a pressure of 2.2 bar to 4.0 bar (32 psi to 58 psi). For many applications, the water must be provided with additives such as corrosion protection agents.
Whether motor spindle or belt spindle - the cooling water chillers of the HYFRA Sigma and HYFRA eChilly/eChilly+ series supply a wide variety of spindles with cooling water reliably and precisely. Our experts will be happy to help you select the right cooler.
