In which industries are our rings used and for what purpose?
K
L

Industries:

  • Mechanical Engineering

  • Mining

  • Armor

  • Aerospace

  • Wind turbine construction

  • Chemical and plant engineering

  • Offshore technology

  • Commercial vehicle construction

  • Shipbuilding

  • Electric motor construction

  • Medical Technology

  • Hydrogen plants (e.g. B. Electrolyzers)

Uses (rings as):

  • flanges

  • Print rings

  • Cell rings

  • Sealing rings

  • Turbine rings

  • Setting rings

  • Bearing rings

  • rotating rings

  • Short-circuit rings

  • Gears

What are the benefits for our customers?
K
L

Cost benefits:

  • Less usable material

  • Lower energy consumption

  • Lower tooling, setup and machining costs

  • Faster manufacturing times

Quality advantages:

  • Deformation-free rings

  • High plan level

  • Very good surface quality

Additional services (on request):

  • Material procurement including factory certificate/TÜV

  • Optimization of components

  • Wage race of individual rings

  • Pre- and final processing according to drawing

  • Heat treatment and finishing

  • Organization of transports

What dimensions can we separate? (Outer diameter, inner diameter, height, wall thickness)
K
L

Example dimensions:

  • Outer diameter: up to 3,500 mm, larger after consultation

  • Smallest inner diameter: 150 mm

  • Wall thickness: up to 430 mm

  • Height (separate ring height): minimum 3 mm, maximum after consultation

How precise are the cutting edges?
K
L

  • Plan flatness: up to 0.1 mm

  • Temperature during separation: approx. 25 °C → cold, deformation-free method

  • Special accuracy in surface quality: e.g. B. 1.293 Ra

  • The separation cuts are so precise that direct further processing or end use is possible.

How wide is the separation gap?
K
L

The separation gap is 3 mm to 4.5 mm, depending on the wall thickness.

What services / special solutions do we offer?
K
L

  • Material procurement, also with factory certificate and TÜV inspection

  • Optimization of components

  • Wage race of single rings

  • Pre- and final processing according to drawing

  • Heat treatment

  • Refinement of the rings

  • Transport organization

  • Traceability by restamping permission until the finished ring

  • Precision separation technology also for Hydrogen applications with the highest requirements

  • Machining of a wide variety of materials, including nickel-based, titanium, aluminum, stainless steels, duplex, etc.
