Once again GST was part of the career day at HTL Hollabrunn.

The participation at the career day of the HTL Hollabrunn has become a yearly tradition for GST, since many of our employees are former HTL graduates – a tradition we are trying to continue in the very same way for many more years to come: Introducing our company to future generations!

We would like to thank the school for the opportunity to present our company via presentation and give the students insights into all our specialist departments and job opportunities.

We had an exciting day and many interesting conversations, with promising future prospects.

We wholeheartedly want to say „thank you for that“!

Korneuburg’s 9th „Bildungsmeile“ brought interested people to GST yet again this year.

Participating companies opened their doors and showed interested pupils the training opportunities of the available apprenticeships within the respective company. The offer was well received at GST – Our visitors were asked what impressions they were able to gather during their visit and what was special about being able to visit a production company on site.

Many conclusive answers were given:
“You see behind the scenes and can get a picture of the field of activity.”
“Lots of times it’s the little things that you see in a company that contribute to your final career choice.”
“It’s the only way to decide for yourself if you feel comfortable in the working environment.”
“You get a first hand observation regarding the atmosphere within the staff and the ways they interact with each other.”

As a training company, we are glad that the annual initiative of the WKO Lower Austria was well received yet again by families and school classes this year and we would like to express our sincere thanks to all participants!

HTL students from OPAVA gain practical experience at GST

Students from the HTL for mechanical engineering from OPAVA – SŠPU Opava – úvodní stránka – are currently completing their Erasmus traineeship at GST.

Only the best students are allowed to apply this kind of internship. If the letter of motivation is convincing, they get the opportunity to complete their internship abroad. The students are accommodated in Vienna as part of the Erasmus program and commute to Sierndorf by train.

With two weeks behind them, the students were able to get acquainted with many areas of our company. GST offers practical experience in the production and mechanical design departments as part of the internship. They are coached and accompanied by our experienced designer DI Vera Sucha, who lives in Brno and travels to GST on a daily basis. As a graduate of the Technical University CVUT Praha – Czech Technical University Prague, she is a role model for the four young students when it comes to mechanical engineering.

In an informal interview, the trainees were asked how they like working at GST:

“The activities in the mechanical design department are very interesting. The 3D program runs in German language, but thanks to intuition and experience, we are still able to work with it very efficiently.”

The two trainees who are currently working in the mechanical production department feel particularly comfortable because they can work together with colleagues of the same age who have also completed their training at GST. Because of everybody speaking English, there is no language barrier between them and if certain technical terms are unclear, translation tools make short work of problems of that nature. Many areas such as the “engraving area for machine plates”, the “spindle room” and the “assembly of assemblies” are presented and activities in these areas are taught.

And what do the young trainees think about their stay in Austria?

 „We are fans of the ÖBB, it is always on time, well equipped and clean”, the way to and from work is rather hectic: „In Vienna, people are constantly on the run, whether on the way to the subway or anywhere else, there is hustle and bustle everywhere”. They enjoy their spare time, including weekend trips to i.e. the Technical Museum in Vienna, which they found to be quite interesting.

But not everything works perfectly: “The stove in the apartment always causes problems, but now it has been replaced” and “Unfortunately, the Austrian beer doesn’t taste as good as the Czech one”. 😉

All in all, the four young people find their stay in Austria very exciting and praise the internship very highly. Some of them could even imagine a life in Austria, although probably not in Vienne, but its more rural surroundings like Sierndorf.

We would like to thank the students for their interest, their cooperation and the overall great exchange!

As part of the 30th anniversary, the employees and their families took a look back on the company’s history and celebrated together. The event was held in the company’s production hall. Speeches were held by not only GST’s managing directors Franz Hein and Günter Hacker, but also the mayor of Sierndorf, Mr. Ernst Kreuzinger.

On behalf of the staff, Mr. Leopold Fröhlich gave a humoristic review of the company’s evolution from his perspective as a longtime employee. Our sales representative in Germany – Mr. Rainer Balles, offered words of greeting and congratulations via telephone message. The Balles company is working for GST for 2 generations already and Germany still is the most important export market for GST.

The Lower Austrian Chamber of Commerce also congratulated for the jubilee and its Vice President Dr. Moser presented an award for 30 years of successful business activity as a company and employer.
After a leisurely lunch, the celebration turned into an open day starting at 1:00 p.m., at which our gates were opened for everyone interested in taking a closer look at our everyday work processes.

A particularly large number of young people took this opportunity to take a look behind the scenes. GST offers apprenticeship programs in the fields of “Metal technician” and “Construction” within our company. Accordingly, the company is an attractive employer for those looking for an apprenticeship.

But not only local people, but also business partners from other countries showed up to celebrate with GST. Long-standing suppliers over the years became friends of the company. In summary, we are very happy to say that the celebration was a big success and used by many sides for a relaxed exchange.

Fact sheet

In 1992, the GST company started overhauling machine tools under the name „GST – Gesellschaft für Schleiftechnik GmbH“. The first new machine was soon sold to Volkswagen AG Germany, and thereby secured our economic success.
The technical know-how was there from the very beginning, since the company was founed out of necessity, because the former employer of the GST’s founders quit the “Heid-AG” in Stockerau, thus giving up the areas of grinding technology and lathes.
Today the company operates internationally under the name GST Grinder GmbH. Around 100 people work at the Sierndorf production site. Customers are located primarily in Germany, but our high-quality machines are sold to places as far away as China and Mexico!

Dear ladies and gentlemen,

This year from May 17th to 20th the GrindingHub in Stuttgart took place for the first time!

It was a great success and therefore we would like to take the opportunity to say THANK YOU to all of you!

We were there and were able to inform our customers (and hopefully future customers) about our latets products:

The GST+ products are available both individually as equipment for your machine and also fully installed as part of our grinding machines – Our high quality makes the difference!

Furthermore we presented our GST Complete Center Drive machine for the grinding of CVT shafts. We hope that we were able to inspire you in terms of your future grinding tasks!

Do you have further questions? We are always happy to advice you and optimize our machines towards your workpieces and requirements – True to our motto: Grinding made for you.

Grinding machine – Automation – Cleaning station – Coolant system – Post-processing station, all from a single source

Siemens could not have chosen a better name for their new control system. For GST Grinder Gmbh ‘One’ is the control system for the entire equipment. A wish that came from many machine operators has been fulfilled. Quite often countless industrial PCs are installed in one system. PCs of machine, automation, feed conveyor, cleaning station, post-process measuring station etc. are connected by different interfaces. In addition to the high costs of many systems, the frequency of malfunctions and their troubleshooting is also rather high. In most cases, a component control system contains much more information than is transmitted through an interface to the “head control – machine control system”. But software maintenance of control systems can also confront maintenance departments with unexpected problems. A post-process measuring station that works with a discontinued operating system and is upgraded on the software side only by replacing the hardware can be very time-consuming and cost-intensive. Automation systems with exotic controls or cleaning stations and coolant systems with small PLCs and hardware interface to the machine control system add to unnecessary complexity, since as well because here as well, any request for improvement or change always has to be made via two control units.

Needless redundancies are eliminated, the result is simplified – true to the principle: as much as necessary, as little as possible

This is why GST Grinder decided years ago to operate the entire system with one control. As a supplier of grinding solutions for large-scale production with very short cycle times and highest production quality, it is crucial to have all system information available. But even for our quick changeover machines, which cover complete part families, automated changeover is only possible with access to the complete system.

Step by step, in-house systems were developed to achieve this goal.

Machine-integrated automation for the quickest possible workpiece changeover allows shorter distances and optimised processes for each workpiece type and at the same time is much more cost-effective than external systems such as gantries or robots. The hardware and PLC programs for the control of external coolant systems and cleaning stations have been in use very successfully for many years and contribute to the understanding of the entire manufacturing process.

Research and development for a perfect grinding process:

As the latest product in this series, an optical post-process measuring station has been developed which is completely integrated into the machine control. There is no longer any need for costly mechanical changeover of the measuring station. All measurement data and information are stored in programmes. Only the cleaning of the workpieces must be ensured to enable the optical measurement. The demands on a PPMS are more than fulfilled. Programs for measuring equipment capability, machine correction, external data transfer and statistics are displayed on the machine control or, if required, on an additional monitor on the machine. But One not only applies to control technology. Mechanical assemblies that are responsible for the required manufacturing qualities are also GST’s own designs. Examples include:

Grinding spindles up to 100 kW with built-in motor, dressing spindles with one or two truing wheels, workpiece spindle systems with up to 4000 rpm or designed as C-axis, driving via centre points by the left and right workpiece spindle, workpiece clamping system by an NC-axis with variable clamping pressure adjustment – even during the process, electric measuring device slide, rotating centre point as tailstock insert, etc.


Leading through knowledge – the future of grinding is digital

One is the understanding of the collective whole, well-coordinated assemblies and processes that ensure quality and cycle time. Only those who know the options for intervention and the variants of the machine assemblies can always turn a wheel somewhere in order to improve quality or cycle time. Because there is no doubt that the future of grinding technology is also digital. Excellent knowledge of its assemblies and processes will make this major task easier. In doing so, GST Grinder GmbH clearly opposes the trend to install the cheapest possible assemblies from Asia or the East in their machines.

New brand “GST+” also a PLUS for other machine tools

On the contrary, with the GST+ brand, GST Grinder GmbH will offer assemblies and products that are especially suitable for retrofitting and upgrading grinding machines of any type. These products, specially developed for large-scale production and machines which can be quickly refitted, can be used in combination, but also “stand-alone”.Manufacturing quality can only be ensured through the precision of each individual assembly. From start to finish.

GST has developed a wide range of highly productive machines for the serial grinding of CVT gear components, entirely flexible and focused on customer requirements. Leading manufacturers already use our machines in continuous operation.

In the course of the “NÖ Bildungsmeile 2021” GST invited all students who are interested in apprenticeships.

Visitors were able to take a peek behind the curtain and get answers to various questions concerning our company and potential career possibilities at GST!

We would like to thank every one of our guests and hope to see them again in the near future!
