Smallest milling machine in the dental world

It all began with the invention of the world's smallest 5-axis milling machine for dental medicine. The Salzburg-based start-up company DMU GmbH, which now has around 30 employees inside, developed it to the point where it was ready for series production. In order to make the adjustments from the prototype to the finished product suitable for industrial use, changes had to be made to the proof-of-concept electronics previously used. The pressure to finalize the product was enormous, as a presentation at the world's largest dental trade fair was planned for spring 2017. In order to quickly implement the milling electronics suitable for series production, DMU commissioned Ginzinger electronic systems with the optimization and integration of the electronic components.

Project start

Integration & Design Optimization

The project was started immediately. The hardware of the prototypes was originally designed for many circuit boards with a high wiring effort. This effort would not be sustainable in series production. The aim was therefore to integrate all functions on two boards - an IO board and a spindle controller board - and to design them in such a way that they were ideally adapted to the milling machine housing and thermally protected. In addition, the assembly effort was to be minimized and hardware and software function groups logically and economically optimized.

Innovation in the smallest space

The confined space situation of the compact mini milling machine presented the design with a number of challenges. These include, for example, thermal management that had to be optimized as well as EMC. The design of the IO board was more time-consuming than expected. Due to the scattering of parameters with a liquid pump, there were also sporadic failures. DMU was able to mechanically intervene and optimize here.

In addition, Ginzinger's team tried to achieve improved control of the pump by means of the software drivers on the IO board, and analyzed the pump parameters through experiments and measurements.

"At Ginzinger, software developers and hardware designers work very closely together. Problems are examined in their entirety. In this task, too, the team found the perfect solution and supported DMU in further optimizing its supply chain."

Partnership implementation

DMU & Ginzinger

Ginzinger works in many projects with its own embedded run-time based on microcontrollers. This simplifies development, testing and series production and has been working in tens of thousands of delivered devices for many years. DMU also uses this run-time as a platform for software development on the IO board. While the application know-how thus remains entirely with DMU, the implementation of the software and the complex sequence management rely on Ginzinger's consistent firmware.

You want to optimize your product?

Cost reduction through proven processes

Microcontrollers have become an indispensable part of modern electronic components. However, instead of programming them again and again in bare-bones and reinventing the wheel, a lean run-time firmware proves its worth over the entire life cycle of the electronics.

You rely on a robust foundation that has been proven thousands of times, you simplify development by means of turnkey libraries, you can rely on an experienced partner to maintain the platform, and you also get test routines at IO level delivered free of charge. All in all, this leads to a great relief for all project participants and to a significant reduction of the overall costs.

Close cooperation

Result: An optimal solution

The joint project has resulted in close cooperation between DMU and Ginzinger electronic systems. Optimizations and extensions to the product continue to be carried out together on an ongoing basis. "We are pleased that in Ginzinger electronic systems we have found a reliable partner, and a nearby one at that, who has supported us quickly and unbureaucratically in the realization of our ideas," says Martin Huber, Technical Managing Director of DMU GmbH.

Hardware and software development as an ideal combination

The project of the customer DMU GmbH from Salzburg shows that the combination of hardware and software development from a single source, coupled with decades of know-how in the production of electronic assemblies, leads to optimal results. Customers benefit from stable, industry-ready products that can be realized quickly.
