FDream® – reaming and honing in one tool

As simple as reaming – with honing precision

FDream® combines reaming and honing in one tool preset to the finished diameter. Machining is performed in one working stroke and can be supplemented by additional spark-out strokes if required.

The technology is designed for precision production bores on machining centres and is particularly advantageous for interrupted through bores. Reaming and honing are combined in one tool – without an additional tool change and without modification of the machining centre.

Operating principle

Reaming cutting edges guided by the honing stones

FDream® is a diamond-equipped multi-stone tool. The reaming cutting edges are guided by the honing stones, combining reaming and honing within the same tool solution.

  • machining in one working stroke
  • optional additional spark-out strokes
  • typical maximum stock allowance approx. 15–25 µm
  • tool preset to the finished diameter

Benefits and applications

High productivity for precision through bores

  • high productivity and dimensional accuracy
  • short machining times
  • simple application and long tool life
  • particularly suitable for interrupted through bores
  • suitable for precision production bores

Typical applications include control housings, turbochargers, valve blocks, crank bores and connecting rods.

Automation and wear compensation

FDream® with µ-matik®

FDream® can be combined with the DIAHON µ-matik®. The mechanical adjustment unit supports automatic or assisted diameter correction and wear compensation of FDream® tools and provides an interface for closed-loop process control.

Application limits

Selective use for the appropriate bore geometry

  • only limited stock allowance per operation
  • FDream® is intended for through bores
  • the process does not generate a “true” cross-hatch as produced by conventional honing with superimposed stroke and rotary motion

For other bore geometries, larger stock removal or a required conventional honing structure, other tool concepts within the DIAHON technology platform are available.

FDream® in practice

Directly on the machining centre

FDream® is available in application-specific tool configurations for the precision finishing of through bores. The examples show different tool versions, the tool head and machining of interrupted bores directly on machining centres.

 

FDream® – precision bores without a separate honing process

FDream® combines reaming and honing in one tool, providing a compact way to integrate precision bore finishing into existing machining centres.

For each application, DIAHON defines the appropriate tool configuration according to the component and bore requirements.
