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.
We would be pleased about your interest in using this new nozzle technology in your company. Please do not hesitate to contact us. The grindaix team is at your disposal at any time.

Learn how you too can retrofit your machine tools and reduce your carbon footprint in Team Grindaix's new article!
Learn in detail about the possible disturbing influences of several areas in two new articles from Team Grindaix. We report on the effects and problems that can arise if the cooling lubricant supply of a grinding process does not meet the requirements and show you how a cooling lubricant supply runs correctly!
A beneficial, customer-oriented production is the goal of every company - and a great challenge at the same time: the requirements for quality, costs and production time must be met and at the same time reconciled with the issue of sustainability. In series production, the cooling lubricant supply has a significant influence on the process result and is often considered the cause of quality variations.
Record and analyse process factors
Nevertheless, the process factors on which these qualitative differences depend are rarely investigated. "Many companies don't even deal with this question," knows Tobias Kaufmann, research associate at the Machine Tool Laboratory of RWTH Aachen University and head of the Digital in NRW transfer project. "But the larger the supply chain becomes, the more machines are connected to each other, the more important it is to know how each individual system is supplied with operating materials such as compressed air, water, electricity or cooling lubricant, where the pressure is and what the temperature or germ load is. Only with the help of the quantitative recording of these status variables in a networked system can differences and errors in the process be detected and compensated for," says Dr.-Ing. Dirk Friedrich, Managing Director of grindaix GmbH. "However, many companies do not yet record these parameters despite their technical feasibility."
Development of a digital process monitoring system
In order to achieve clear predictions on the supply of operating materials in production, Digital in NRW and Grindaix are working on "Resilient process control through AI-based cooling lubricant supply during grinding", the official title of the transfer project. The idea behind this is the development of a digital process monitoring system. With the help of artificial intelligence, errors and deviations in the supply of the machines are to be detected, recorded and recommendations for action developed in the future. The transfer project with Digital in NRW sets the course for a sustainable cooling lubricant supply with high quality standards. "Predicting failures in the supply chain and taking direct action to avoid interrupting the production process is becoming increasingly important," says Kaufmann.
From the actual state analysis to testing
The experts from Digital in NRW first recorded the possibilities of a centralised or decentralised cooling lubricant supply of a machine tool as part of an ACTUAL analysis and identified communication interfaces. This was followed by the development of a target concept: in close cooperation with the company, a suitable sensor system for recording relevant coolant supply parameters was developed, as well as a technical solution concept for digitally networking the individual interfaces. "We are currently testing coolant monitoring with the latest fluid sensor technology in a research environment to generate and analyse data," explains Tobias Kaufmann.
Simulation on the demonstrator
In the machine tool laboratory in Aachen, work is being carried out on analogue test benches and a demonstrator with pipeline, pump and sensor technology is being set up to simulate the various process sequences and causes of faults: What happens when a pipe becomes clogged? What if the pressure is too low? "The challenge is to create a database that the algorithms can work with," explains Tobias Kaufmann. The connections between cause and effect must be researched, and recommendations for action must be developed. "To do this, we have to record scenarios from real operations and transfer them to the test bench in order to record their effects on the data," says the project manager. The core of the transfer project is to develop a methodology for plausibility checks that can later be transferred to various applications. High-quality plausibility checks provide "the basic prerequisites for subsequently derived recommendations for action, which should ultimately improve process control and not cause a machine crash." The more data available, the greater the later coefficient of determination of the algorithms.
More efficiency, less waste
Subsequently, three representative cases are to be transferred from the demonstrator to the real environment and the findings are to be used in real production. The plan is to use the developed concept in an assistance system on a series machine and prepare it for practical use. "Small and medium-sized manufacturing companies can certainly benefit from the development," Tobias Kaufmann emphasises. "The use of this system creates resource efficiency, more process reliability and the reduction of rejects, which in turn can save costs."

The solution approach via the digitisation technology available from Grindaix and the associated consulting services of professional and experienced production engineers (audit resource efficiency), is intended to provide a concretely implementable technical orientation for manufacturing companies to monitor the use of resources in production technology as quickly as possible and to reduce it sustainably via economically effective approaches. The audit focuses mainly on the company-related consumption of operating resources in terms of energy, water, materials, operating supplies and auxiliary materials. The use of these resources is reflected in different consumption groups of the manufacturing companies by using a digitalised monitoring system (resource monitoring) of the Grindaix GmbH. This includes the production processes (manufacturing processes), production machines, transport systems, assembly systems, industrial buildings, CO2 footprint of semi-finished and unfinished goods (components) as well as retrofitting / recycling processes of disused products after return.
The resource "knowledge" in production technology, in terms of the successful management of a value-added chain and the technical interaction restrictions presented in the context of this model approach in the optimization of the overall resource consumption, is probably the most valuable resource in production companies. The superior aim of digitized assistance systems in form of resource monitoring is to secure this resource in the long term, not to lose it to competitors or generally through staff fluctuations.
In the future, such digitalized resource monitoring systems will represent the decisive unique selling point in the competition of globally fluctuating production companies, alongside the equally important resource of employees and their qualifications. In order to secure your company's own knowledge base in the future, digitized monitoring systems are irreplaceable as a database for digital assistance systems with self-learning capabilities (artificial intelligence).
The Grindaix GmbH is offering production companies digitalised monitoring systems, services and software concepts to ensure resource-efficient production technology.
For many years, efforts to achieve an ecologically sustainable production technology were seen as costly rather than cost-saving. This approach of the company management has changed. Today, manufacturing companies are increasingly implementing measures to reduce the consumption of materials, energy, water, operating supplies and auxiliary materials.
However, mainly small and medium-sized companies often lack technically experienced starting points and orientation aids to be able to implement sustainable resource efficiency in production technology in a practical and cost-effective manner without restrictions in product quality and yield.
Innovative approaches for the successful digitalization of production environments arise from the monitoring of resource consumption. The latter requires a modular and standardized monitoring technology in the form of an easy-to-install IT infrastructure for existing machines. The production and delivery of such an IT infrastructure is the main contribution of the Grindaix GmbH. We supply our customers with a complete package (ready to connect) for simple, but accurate and reproducible data acquisition in the context of all their resource consumption, for small, medium and large companies and all sensors common in industry.

In addition to all three of the above-mentioned functions, the new Grindaix multifunction nozzle GRX-X also combines the discharge of the air cushion rotating with the grinding wheel.
The multi-chamber principle allows our customers to adapt nozzles to the specific application and process. All chambers of the GRX-X multi-function nozzle are separately supplied with cooling lubricant in terms of coolant pressure and volume flow by valve control and are fed back with signals from the grinding machine.
To prevent clogging of grinding tools in the future, the tool cleaning function is switched on or amplified on the basis of active power signals. In order to avoid "aquaplaning effects" between tool and component caused by coolant supply, the supply pressure at the main cooling nozzle is reduced via vibration signals from the grinding spindle.
We would be pleased to present the multi-function nozzle to you in your company. You can find your contact person here.
We look forward to your contact.
The nozzle acts as a spoiler and directs the air rotating with the grinding wheel away from the grinding wheel surface so that a coolant jet of coolant can reach the machining area as unhindered as possible. A suitable cooling lubricant jet (pressure, jet type, volume flow) is used to tap the air cushion directly on the grinding wheel surface. The cooling lubricant jet follows the wear-related diameter reduction of the grinding tool in a constant effect, without nozzle adjustment.
We would be pleased to present this product to you in your company. You can find your contact person here.
We look forward to hearing from you.

Numerous commercially available sensors were tested on our own test benches, but were not found to be good. Either they were too inaccurate, not wear-resistant enough or simply impractical. The Grindaix team decided to develop the sensors themselves in order to live up to the performance promise to its more than 800 customers in the German market alone. The sensor is AI-capable, modular in three size classes and available from June 2019. A product presentation can be found on the
Grindaix Innovation Days 2019 will take place in Cologne on November 19-20. We are looking forward to meeting you!
