Furthermore, with the help of this new nozzle technology, it is possible to significantly increase the service life of the grinding tool, especially for face shoulder-, tool-, flat profile-, crankshaft-, camshaft- and gear profile grinding. The return on investment after purchasing the customized GRX-X cooling lubricant nozzle is achieved within one year.
The nozzles can be manufactured from wear-resistant stainless steel (conventionally produced) or from titanium alloys using the 3D printing process. All Grindaix nozzles are suitable for operation with oils and also water-based cooling lubricants (emulsions). On our state-of-the-art Grindaix test rigs, the nozzle characteristic consumption curves per nozzle function chamber are generated and provided to the customer for use within a process-adaptive control of the cooling lubricant feed conditions. The novel nozzle combines 4 different nozzle functions simultaneously and time-parallel in one component. In a first step, the nozzle expertly diverts the air cushion rotating with the grinding wheel via a targeted liquid jet. The liquid jet compensates for a wear-related loss of radius of up to 6 mm during its wind discharge in a process-safe manner. A second nozzle stage cleans the grinding wheel topography from process-related clogging. In a third step, the now free bond pores are selectively impregnated with cooling lubricant. In the fourth and final functional step, the contact zone between the component and the grinding wheel is additionally supplied with cooling lubricant via a cooling nozzle.
With the aid of this nozzle technology, grinding machine manufacturers can use a single standardized nozzle component to reduce the number of variants in the machine, instead of the multiple nozzles per grinding spindle, which are sometimes designed very differently. This system can be standardized and modularly constructed so that it can be easily adapted to any application without always having to order completely new nozzles. It reduces the possibility of errors in nozzle position, adjustment of spray angle, etc.
In the best case, the nozzle is supplied for all 4 functions, including the cleaning of the grinding wheel, by only one, simple and inexpensive centrifugal pump (<25bar). The pressures per chamber of the nozzle can be controlled either via valves or, of course, via frequency-controlled pumps and can be regulated in a process-adaptive manner, e.g. via the active power signal of the grinding spindle. The nozzle design is adapted to the application-specific grinding geometry. All pressures in the nozzle chambers can be tapped separately if desired. Recording of the cooling lubricant supply data, for example via a Coolant Monitoring System, or the machine control system serves to ensure the application-specific reproducibility of successful process settings. This nozzle technology allows the grinding technology user to achieve a much more economical process control immediately after successful installation.
