Konrad Seidler Maschinenbau GmbH
Vertical turning lathes & contract machining
The engineering company was founded in 1965 by Konrad Seidler and has been based in Neuss-Holzheim, near Düsseldorf, ever since. Today, the company is run by the second generation of the family, Robert Seidler. This means we have more than 60 years of experience in mechanical engineering and the machine tool industry.
Over the past decades, numerous conventional machine tools have been modernised and converted into CNC-controlled machines. Drawing on this long-standing experience, the decision was made many years ago to also develop and build our own machine designs. Under the name VERTIMAXX, we produce high-performance CNC vertical turning centres for demanding applications in metalworking. In addition, we continue to offer repair, modernisation and retrofitting of machine tools.
A modern machine park enables us to achieve a high degree of vertical integration and a consistently high standard of quality. At the same time, we have continuously expanded our contract manufacturing and machining services in recent years and produce precision components for various industrial applications.

Experience, precision, flexibility, reliability and a fleet of state-of-the-art machinery
Vertimaxx Vertical turning lathes – manufactured in-house
One of our areas of expertise is the manufacture, repair and retrofitting of traditional CNC-controlled vertical turning lathes.
Our product range, marketed under the registered name VERTIMAXX, currently comprises four different models.
VERTIMAXX 2000 / 2500 / 3000 and MINIMAXX
Faceplate diameter from 1400 to 3000 mm
Workpiece height variable from 1200 to 2500 mm
Thanks to the modular design of the machine tools we manufacture, we are able to offer a very wide range of products. These universal turning, drilling, milling and grinding centres are currently equipped with up to 6 axes.
Contract manufacturing / Contract machining
We also offer contract machining and the manufacture of individual parts and medium-sized batches based on samples or drawings.
Our experience covers various materials such as aluminium, grey and red cast iron, all types of steel, stainless steel and Stellite. Through partner companies, we can carry out material treatments (tempering, hardening, annealing) and surface treatments (nitriding, galvanising, chrome plating, etc.).
Component manufacturing, overhauls and repairs are possible thanks to our many years of experience in mechanical engineering. Continuous quality assurance processes ensure high standards. Our machinery comprises both state-of-the-art and conventional machines for milling, grinding, sheet metal working, sawing and welding.
