grindaix GmbH was founded in 2004. The goal and vision of the young company was to provide a solution for customers that avoids the waste of cooling lubricant in the grinding process and makes it more productive and of higher quality. The process-optimised cooling lubricant supply solutions enabled grindaix to establish itself in the market for cooling lubricant supply solutions. In 2021, it was sold to the world's largest industrial fluid manufacturer, Quaker Houghton, giving it the opportunity to further expand its vision and enter new markets. All this happened under the leadership of the founder and managing director of grindaix GmbH: Dr. Ing. Dirk Friedrich.
About 20 years after the foundation of the company, the long-time founder and managing director Dr. Ing. Dirk Friedrich MBA leaves the company. After successfully managing this company for the last two decades, he passes the baton to his successor Roman Stabauer M. Eng. who now leads the company as the new Managing Director.

"I am very happy and it is a great honour to succeed Mr. Dirk Friedrich as Managing Director of grindaix. Since the beginning of my professional life, I have been involved with the topic of adapted and efficient cooling lubricant supply in grinding processes and thus there has also been a close cooperation with grindaix for a long time. After joining the company last year as technical manager, I am now looking forward to taking the next step and successfully continuing the business of grindaix in close cooperation with Quaker Houghton."

Under the new management, the grindaix team will continue to ensure that your grinding processes are designed to be resource-efficient, productive and of high quality. In the future, the product variety will be further increased by the development of innovative sensors in close cooperation with Quaker Houghton. If you are considering optimising the cooling lubricant supply to your grinding processes, please do not hesitate to contact us.

Quaker Houghton continues to pursue building our Industry 4.0 business. “Our strategic acquisition of Grindaix is a critical step in bolstering our Fluid Intelligence offering. With this acquisition, we are strengthening our automation capabilities to ensure we bring superior and differentiated value to our customers. Fully brining the Grindaix team into QH will help us strengthen our automation capabilities in the coming years” said Joe Berquist

Dr.-Ing. Dirk Friedrich will continue to be in charge of the company's management. "We are very pleased that we, as a German innovation provider, are able to offer our new globally successful partner technological added value in the context of optimizing cooling lubricant systems. Together with our expertise in the field of cooling lubricant supply in grinding technology, the additional high level of cooling lubricant competence of our new partner will now lead to a more comprehensive offer to our customers. This will enable us to support our customers much more intensively in mastering the ever-increasing complexity within the framework of productive, high-quality grinding technology that is free of grinding burn."

To achieve consistent results in manufacturing, coolant lubricants must be maintained. Most of the maintenance is done through the process of coolant filtration. Through coolant filtration, contaminants are separated from the cooling lubricant and removed from the coolant circuit. Thus, coolant filtration is primarily responsible for ensuring that the coolant purity is as consistent as possible. Without MWF filtration, the cooling lubricant would become so contaminated after only a few process runs that a stable process would no longer be possible. In addition to the lack of quality of the product to be manufactured, this circumstance would primarily have an impact on the economic side. Without coolant filtration, the coolants would have to be replaced continuously, which would entail considerable costs. In practice, various systems are offered for coolant filtration, some of which differ considerably from one another in terms of functional principle and design.

In the magazine article on filtration in the coolant circuit, you will learn which filtration processes are available and how they differ.

Here you can go to the first part of the centerless grinding.

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.
