Overview
Fully customised grinding solutions for your part. Drawing on decades of application expertise and manufacturing insight, Overbeck (part of Danobat Group) transforms know-how into fully optimised, purpose-built grinding solutions. Fully engineered machines adapt hardware and software specifically to the part and process, delivering higher precision, stability and throughput.

Custom-engineered approach

• Tailor-made machine architecture designed from requirements and part geometry.
• Close collaboration with manufacturers to define process, hardware and software needs.
• Integration of custom mechanical layouts (e.g. U-axis), multiple dressing units and tooling to meet complex geometries.

Real-world case study (examples)
The ILD family (example: ILD-700) is designed for large bearings and complex aerospace components, delivering high precision and stability for IDs, ODs, raceways, tapers, shoulders and ribs. The IED-1200 example demonstrates complete internal and external grinding in a single setup: independent cross-slides for ID and OD grinding, high rigidity and integrated in-process measuring systems delivering sub-2 µm results in roundness, concentricity and cylindricity.

Software
Software is engineered to match each customised machine. Customer-specific programs (polygons, eccentrics, squares, punches, etc.) are managed in a graphical catalogue. Once a process type is selected, entering a few part-specific parameters automatically generates the grinding profile, enabling fast, precise setup and repeatability.

Applications & benefits

• Special applications where standard grinders are insufficient (aerospace, bearings, spindles, complex components).
• Complete grinding cycles in a single setup to ensure ideal references between internal and external features.
• Enhanced thermal stability, rigidity and precision for high-value components and high-volume production.

Caractéristiques / spécifications techniques

• Machine type: purpose-built, custom-engineered internal/external grinding machines (Overbeck).
• Process capabilities: internal grinding (IDs), external grinding (ODs), raceways, tapers, shoulders, ribs and complex transitions in a single setup.
• Mechanical features: independent cross-slides for ID and OD; optional U-axis for large diameters/lengths; high-rigidity construction for precision.
• Dressing systems: fixed, rotary, radius or roller dressers; multiple dressing units; turret arrangements possible.
• Measuring & control: optional in-process measuring systems and customised software generating profiles from part parameters.
• Typical precision: sub-2 µm achievable for roundness/concentricity/cylindricity when configured with appropriate measuring systems (example IED-1200).
• Workpiece capacity (example indication from imagery and case studies): work head / workpiece combinations up to ~1300 mm length and ~500 kg (application dependent).
• Examples of models referenced on the page: ILD series (e.g. ILD-700) and IED series (e.g. IED-1200) as purpose-built solutions.
