CNC grinfing
High-end machining of milled and turned parts

Our competence in grinding

Surface, cylindrical, profile, non-circular and thread grinding

With our sophisticated grinding technology, we give the finishing touches to surfaces after milling or turning.

Highly precise contours on many technical materials can be realised within a very short time thanks to our highly flexible and quickly adaptable CNC grinding machining centres.

SK TECHNOLOGY’s outstanding strength is internal cylindrical grinding. This machining process is used mainly for cylindrical, stepped and tapered bores. Here, bores are ground in the rotating workpiece. The focus is mainly on dimensional accuracy, roundness and coaxiality.

The necessary grinding wheels are dressed using a rotating diamond roll. This results in the finest profile shapes with enormous perfection.

Our customers benefit from state-of-the-art machinery, coupled with the unbeatable experience of our employees. You too can rely on our grinding technologies.

Honing – precision machining

Honing is a machining technology that is carried out in the µm range. Therefore, it requires absolutely top precision. Our honing machines guarantee maximum accuracy in terms of shape and dimension and the highest surface quality of the inner surfaces during production.

Lapping – high-precision plane surfaces

Lapping is considered a fine machining technology that is gentle on the material. The lapping process helps us achieve the highest requirements for shape accuracy, dimensional tolerances and surface qualities in the 0.1 µm range.


  • Honing: max. machining size Ø 1,5 – Ø 50 mm,
    depth 130 mm
  • Lapping: external Ø 480 mm, working wheels Ø 1.200 mm


  • Prototype machining
  • Zero series production
  • Small-batch production
  • Production of medium batch sizes


  • Stainless steel, as well as all commonly available steel grades
  • Titanium and other materials
  • Non-ferrous metals


We work with grinding machining centres of the latest generations:

  • 5 CNC cylindrical grinding machines
  • 4 CNC profile and surface grinding machines
  • 1 CNC vertical multi-process grinding machine
  • 1 honing machine
  • 1 lapping machine
