Precision grinding
Precision down to the details

While expanding hard chrome-plating services over the last three decades the Kronenberger family also successively expanded the area of precision grinding. For this a factory building with a total area of more than 1,600m² was built in 1999.

On top of that we have made considerable investments in the modernisation and expansion of our machinery. Constant updates facilitate our success in the Industry 4.0 age and enable us to continue to play a leading role among the competition.

We can grind your parts of up to

  • 1m diameter
  • 6m in length
  • 8t piece weight

exactly according to your requirements.

Surfaces and dimensions

Maximum part dimensions:

∅ 1,000mm / ↔ 6,000mm

Piece weight up to 8t

Surface profiles and surfaces

We can produce all common surface profiles. This includes the grinding of special freely-defined curves, such as concaves and convexes. Regardless of whether it is chrome, ceramic or carbide coatings, whether matt, polished or mirror finishes: we can produce peak-to-valley heights of up to Rmax < 0.025µm. .

We can process cylinders, rolls, special parts, prototypes, and large and small production runs. Together with our hard chrome-plating department we also offer the repair of used rolls or cylinders.
