Digitization enables resource-efficient production technology

The need to establish greater efficiency in the consumption of resources as a competitive factor within production technology - undeniable. Due to the clearly noticeable climate change and its negative effects on the living conditions of people, we are all increasingly called upon to face this great challenge without delay. This also involves providing the manufacturing industry with suitable tools to enable it to achieve high resource efficiency in a technically and economically sensible way.

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.

Grindaix reduces the consumption of operating resources in manufacturing industries

Methods to reduce costs in production companies are constantly being improved and have already been successfully applied. The main focus here is on improving labour productivity by successfully exploiting rationalisation potential, since the labour cost share in high-wage countries represents a significant competitive disadvantage compared with low-wage economies.

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.

A new generation of innovative Grindaix cooling lubricant nozzles follow a multifunctional approach. A cooling lubricant nozzle was previously used either to cool the machining area, to clean the grinding tools or to soak the grinding wheel bond.

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.

GRX-LAS the "air cushion killer"

At the Grindaix Innovation Days 2019 a very simple retrofit option for grinding machines was presented to effectively reduce the coolant displacement effect of the air cushion on grinding tools.

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.

Novelty: GRX-Q pressure/flow sensors highly accurate and wear-free

What is needed, but not for sale, the Team Grindaix develops itself! This also applies to the topic of volume flow sensors. A high-precision volume flow sensor for liquid media, which simultaneously indicates the pressure under which the medium flows and is as wear-resistant as possible, was the challenge that the innovators from Kerpen (Rhineland) had to face.

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!
