KŐRBER SOLUTIONS
Schaudt Mikrosa GmbH
Schaudt Mikrosa GmbH is synonymous worldwide for cutting-edge technology in cylindrical, noncircular and universal grinding between centers, as well as in centerless external cylindrical grinding. since 2009, the company combines the two long-established brands SCHAUDT and MIKROSA in a modern factory in Leipzig.
SCHAUDT is the brand for the automotive industry and its suppliers. It offers sophisticated technological solutions for cylindrical, noncircular and eccentric grinding. Our highly experienced experts also have unparalleled expertise in the high-precision grinding of long and heavy workpieces like those required for roll grinding, for example. Within this broad application range you obtain everything from a síngle source from sCHAUDT appIication development, technology, assembly and sales.
MIKROSA is the technology and market leader in centerless external cylindrical
grinding of rotationally symmetrical parts. The modular design of the machines means that you obtain a solution with handling and automation individually tailored to your grinding task. The technology spectrum extends from precision infeed grinding in many different variations through to superproductive throughfeed grinding. This allows you to machine a very large variety of work- pieces, from small jet needles through to large shafts.
Long tradition and cutting-edge precision and quality place SCHAUDT and MIKROSA among the world s market and technological leaders today.

Top quality ín centerless cylindrical grinding
Centerless grinding Technology spectrum one grinding principle, three sizes - the KRONOS series from M1KβoTShAe following grinding technologies can be implemented on the machines in offers centerless cylindrical grinding technology in the high-precision than K- RONOS series, depending on the task:
Centerless grinding is a special type of external cylindrical grindin g, lnfeed grindíng - straight which is primarily used in the series and mass production of cylindric al lnfeed grindìng 60 / 15 angled components. Two different process variants aгe available: throughfee d lnfeed grinding in single or multiple production grinding and infeed grinding. Thanks to the linear workpiece support oп lnfeed grinding in several operations
the work rest and the regulating wheel, пo deflection effects develop du- Oscillating infeed grinding ring grinding. 

Applications
The application range of the KRONOs series is very broad:
Hígh-precısion small components for injection technology shaft-type components for transmissions and motors
Rings and rolling elements
Special materials such as ceramic
Bars and other long, slender workpieces
Small components for medical technology
Machine expertise on all levels
