In a nutshell - the topics of our grindaix magazine
In our grindaix magazine, we regularly publish interesting articles around grinding. We not only deal with the aspects of lubricoolant supply during grinding, but rather integrate them into the overall context of this complex processing task. In addition to the technical basics, our articles always contain valuable tips from our many years of experience. We always know what we are talking about, because we create our magazine articles based on our own experience and knowledge.
Whether you are interested in grinding or searching for specific information, in our Grindaix magazine there is an interesting article for every reader.
Our technical contributions
ROI-Digitization
Projects
The digitization of production units offers a wide range of possibilities for networking existing machines and systems. In this article, we offer you a brief orientation in the subject matter.
Zero Emission Production
Zero Emission Production helps to reduce carbon dioxide emissions permanently while at the same time increasing the availability of production resources and avoiding the waste of operating materials.
Reduce CO2 consumption
A high-tech company based in the south of Cologne set out years ago to develop and distribute product solutions to avoid waste in the use of operating materials in industrial production.
Resource-efficient production technology
The exclusive interview with the CEO of Grindaix GmbH promises an interesting perspective on the topic of resource-efficient production technology.
How to penetrate the air cushion
To overcome the air cushion, various solutions commonly used in practice are applied. In all cases, the aim is to mitigate or completely avoid the negative influence of the air cushion on the cooling lubricant jet.
Fluidic consideration of the air cushion
Based on the described phenomenon of boundary layer adhesion, additional studies on the shape and characteristics of the grinding wheel air cushion are available in the literature.
Interference during grinding - Part I
The goal of a cooling lubricant supply that meets the requirements is thermal damage-free component machining to achieve the highest form and dimensional tolerances in the shortest machining time.
Interference during grinding - Part II
The grinding process involves various disturbance variables that can negatively affect the supply of cooling lubricant in line with requirements.
Coolant supply during centerless grinding
Among the cylindrical grinding processes, centerless processes occupy a special position with regard to their process design and range of application.
Process design and optimization
The change in the automotive industry and the targeted reduction of CO2 emissions, e.g. in aviation, pose new challenges for grinding technology. The machining of thin-walled lightweight components and the processing of high-temperature materials are gaining in importance.
Free jet of a coolant nozzle
The exit velocity of the cooling lubricant within the grinding technology is high. It is always turbulent free jets of coolant nozzles, it is a typical flow process of a nozzle.
GRX-X multifunctional nozzle
The multifunction nozzle developed by the Grindaix team consists of three main nozzles: the cooling nozzle to cool the grinding wheel, the cleaning nozzle to clean the grinding wheel coating from clogging and abrasion and the so-called GRX-LAS Liquid-Air Spoiler.
GRX-Q - Flow measurement
Flow measurement is part of the metrological determination of a volume flow Q or mass flow m=ρ∙Q. This is done in dependence of a measuring cross section A of a closed pipeline or an open channel.
GRX-Q - Volumetric measurement methods
The volumetric measuring method is based on the measurement of partial quantities of a medium to be measured. The medium passing through a defined measuring chamber or via an analogous rotation of measuring blades is added up.
GRX-Q - Displacement meter
In displacement meters, the movable measuring walls are driven by the medium to be measured. The movement is detected and counted.
GRX-Q - Differential pressure method
Flow measurement using the differential pressure method is frequently used in chemical engineering and comparable industries.
GRX-Q - Flowing
bodies
With this type of flow measurement floating bodies, spring washers or flaps are exposed to the flow. After the differential pressure method, variable area flow measurement is one of the most frequently used methods.
Electromagnetic flow measurement
In electromagnetic flow measurement (EMF), an electrical voltage is generated by the interaction between the flow velocity of a liquid and a magnetic field. This principle is based on Faraday's law of induction.
GRX-Q - Ultrasonic flow measurement
Ultrasonic flow measurement, also known as ultrasonic transmission principle, works on the basis of the propagation speed of sound waves, which changes in moving liquids with the flow speed of the transmission medium.
AI - What is that?
Basically, the concept of artificial intelligence is technically misplaced in this context. Artificial intelligence describes the academic endeavours of humans to research the human brain and its performance and to map it with the help of computer-aided methods.
AI - Autonomous production
Production technology is increasingly characterised by the use of computer-supported knowledge management systems. A distinction is made between expert systems that pursue a deductive learning approach and inductive optimization methods.
AI - How do you proceed?
The first step in context is to start the implementation as soon as possible and not to wait for a competitor to come up with a solution. Because this solution, if it would be accessible at all, can certainly not be simply copied or purchased at the push of a button.
AI - possibilities
The possibilities that result from the successful use of a production environment that is monitored according to requirements and controlled by artificial intelligence are diverse and often unexpectedly high in potential.
AI - Challenges
As already described in Chapter 3 (AI - How to proceed), the algorithms for the successful application of machine learning in production engineering require the highest possible number of good data. Good data are data whose values are basically as correct as possible.
AI - Risks
In addition to the many good possibilities and high potential benefits of artificial intelligence in production technology, there are also risks to be considered when implementing such capability tools.
AI - Obstacles
The biggest obstacle to the implementation of digitisation technology at present is the often prevailing irritation of the decision-makers responsible for production as to how the project should be approached at all.
AI - Implementation
The following is an example of how a digitisation project can be successfully implemented.
Types of lubricoolant
In addition to emulsions of various concentrations, in which various additives are used, the use of grinding oils is also familiar. The areas of application, advantages and disadvantages, as well as the most important selection criteria for cooling lubricants have been put together for you.
CNC grinding machines
rinding machines are state-of-the-art machining centers that are indispensable for producing a perfect surface finish today. By using computer-aided CNC controls, these high-performance machines also work completely automatically.
Frequent problems during grinding
Although grinding is a widely used manufacturing process, it is complex and in many places it carries the risk of making mistakes, with an effect on efficiency and component quality in all cases. What should be considered in detail and what are actually the most common mistakes when grinding, you can read here.
Lubricoolant filtration facilities
The filtration is a crucial part of the coolant supply with great influence on the manufacturing results and the efficiency. We have described and compared the usual filtration methods for lubricoolant.
Cooling during grinding
Grinding creates a great amount of heat, which occurs due to process-related friction. This heat must be dissipated reliably, which is why grinding processes require reliable cooling. What is important here, you can look up here.

Filtration in the coolant circuit
To achieve consistent results in manufacturing, cooling lubricants must be maintained. Most of the maintenance is done through the process of coolant filtration.
