The Studer Mikrosa GmbH in Leipzig has specialized in all applications of centerless external cylindrical grinding. With the KRONOS series we place a range of flexible, precise and highly productive solutions at your disposal. Equipment investments that pay off.

The roots of the Studer Mikrosa GmbH go back to the year 1878 and since 1949 centerless external cylindrical grinding machines are produced in Leipzig. We manufacture sophisticated precision machines, including the automation components, in all common sizes and adjust these to our customer’s wishes.

On account of our competence in the co-operation with SCHLEIFRING Group we are among the market and technology leaders in the international field. We count nearly every well-known manufacturer from the automotive industry and suppliers, from the mechanical engineering industry as well as from the bearing industry to our customers.

We see the further development of all flow and work processes to the benefit of our customers as a continuos challenge. We are in permanent dialogue with our customers and are able to find specific solutions this way. Moreover, we co-operate with the best researchers from universities and scientific institutions, such as e.g. from Laboratorium für Werkzeugmaschinen und Betriebslehre at RTWH Aachen (University of Technology), in the field of research and development. This means we can always offer the latest technical expertise. This is what we see as a partnership co-operation which is customer-oriented.

A leading position on the market is not a coincidence but the result of a continuous, customer and process oriented development. Quality and innovation in grinding – values which MIKROSA has represented for years.

- Centerless Grinding Machine - KRONOS S
  The KRONOS S is the ideal system decision for economical precision processing
  of small parts. The special feature of the KRONOS S: It can be converted into a 15°
  inclined plunge cut machine within 2 hours. In this way, applications which were only
  possible between centres can be processed alternately. If we look at it this way, the
  KRONOS S is really "two machines in one". It has been designed for universal use
  even with the smallest of batch sizes.
  The KRONOS S provides outstanding overall economy, above all in combination
  with the CBN high-speed technology.
- Centerless Grinding Machine - KRONOS M
  With the KRONOS M, we provide a modular concept with a series of benefits which
  pay their way. All the machines are naturally equipped with a SINUMERIK 840D CNC
  control. Workpieces with a maximum plunge cut length of 245/395 mm
  and a diameter of up to 100 mm can be machined.
  The KRONOS M is very flexible in application. The grinding spindle is designed
  as a function of the grinding task: bearings on one side up to a grinding wheel
  width of 250 mm or on both sides up to 250 mm and 400 mm grinding wheel width.
- Centerless Grinding Machine - KRONOS L
  The KRONOS L is designed for processing of large workpieces. It has been designed
  and equipped for power and volume performances. The machine has been purposely
  enhanced to include a meaningful range of technical improvements and promotes
  immediate cost reducing production advantages for customers’, e.g. a higher cutting
  performance and a further reduction of auxiliary and changeover times.
- Centerless Grinding Machines - configuration packs
  - KRONOS speed
  KRONOS S with High-Speed-Centerless-Loader
  Special machine for diameter grinding of taper rolls in throughfeed grinding
  - KRONOS L dual:
  Combination of two grinding processes in one clamping: „Grinding between centers“
  and „Centerless grinding“
- Centerless Grinding Machines - standard machines
  - KRONOS eco:
  Standard machine for throughfeed grinding


The greatest share of our customers derives from the Automotive and Supplier Industry. Mikrosa offers solutions, individually developped in co-operation with the respective client, for grinding various applications, such as injection needles, universal joints, pintles, camshafts, crankshafts, gearshafts, pistons etc. with highest precision. Mikrosa-Machines guarantee maximum planning security in just-in-time production.

Many machines of every day usage and in industrial production contain applications, which are typically centerless grinded, because of highest accuracy demands,
e.g. control pistons, compressor shafts, valve pistons, motor shafts, ball-bolts
and more. Mikrosa is also in this domain a partner on whom you can rely on.

In the Bearing Industry Mikrosa is one of the market and technology leaders. Mikrosa, together with with its long standing partners, is constantly endeavoured to improve current grinding methods and to invent and realize new solutions, especially
in the thrufeed-grinding sector. Typical applications are bearings, cylinder rolls,
barrel rolls, cone rolls.

Even in the Aviation and Aerospace Industry many manufacturers trust in the Mikrosa centerless grinding know-how to machine applications like bolts, pins, pistons
and needles.

The Tool and Die Industry is a further task for the highly precise technology of Mikrosa machines. Many notable manufacturers are convinced of the KRONOS series benefits. Typical applications are borers, pins, eccenters, guidance pipes, ejector pins.
