Double-sided Machines for Grinding and Polishing

We also offer the optimization and retrofit of used double-sided grinding, lapping and polishing machines. Working 30 years in the development and production of diamond tooling as well as producing precision optics and semiconductor substrates gives us the background to understand your requirements and transfer them into the needed machine.

Please contact us to discuss your specifications.

Grinding Wheels

We develop and produce grinding wheels for all machine types and sizes – for single- as well as double-sided machines. Depending on your very needs, we will create the best grinding wheel to produce your components.

We gladly consult you:

  • At processing very sensible materials such as calcium fluoride or germanium
  • At grinding and polishing very hard materials such as sapphire, silicon carbide or spinell
  • When it comes to producing very thin substrates
  • At high requirements on flatness, parallelism, roughness or other specifications, that are important to you
  • Already during feasibility studies or prototyping phase to create viable solutions

Segmented

Segmented grinding wheels are used for grinding very thin parts or a high density of components. The segmentation of the grinding wheel is above all to avoid tilting of the processed parts and to improve the edge sharpness.

The gap between the segments can be chosen flexibly and is usually determined by the size of the smallest components that need to be processed.

Pelleted

Pelleted grinding wheels are used where high removal rates combined with relatively low pressure are required.

These grinding wheels ensure a good removal of chipping and therefore avoid that clogging of the tools.

Grit size and pattern are completely flexible. We produce grinding wheels customized exactly to your production needs.

Fully Covered / Smoothed

Fully covered grinding wheels are typically used when many small items need to be processed at the same time. In the micro optics or watches industry, for example, several hundred components are ground simultaneously.

The full coverage ensures that all components are processed evenly on the grinding wheel. It avoids clipping or tilting of parts during the transition from one grinding segment to the next.

Subsequently, the edge quality of the components is improved and the risk of damage minimized, while the surface finish is significantly increased.

Grinding & Polishing Pellets

Grinding & Polishing Pellets

We produce diamond pellets in various dimensions, grit sizes and chemical-mechanical properties. They are used as a single pellet tool or combined as a multi pellets on radius- or plano grinding wheels.

We have specialized on resin and hybrid bonded tools. Those two bond types give us the highest degree of freedom in directing the chemical, mechanical and physical tool properties.

The hybrid bond combines the benefits of metal bonded tools (cutting performance, endurance and good cooling properties) and resin bonded tooling (homogeneous scratch-free surfaces, very low sub surface damage, optically measurable after grinding, reduced polishing times).

Whatever bond type you choose – all dopa tools are characterized by their ability to achieve very high surface cleanliness as well as high dimensional accuracies. Therefore, they are widely used in precision optics, semiconductor, medical or space applications.

Our polishing pellets substitute polishing compounds such as polyurethane pads, pitch or composite materials. They consistently hold their shape and enable you hereby producing very precise workpieces.

We always have large amount of our standard pellets on stock and can dispatch your order very quickly.

Benefits of Diamond Pellets

  • Excellent cutting performance, endurance and high heat delivery from cutting zone
  • Homogeneous scratch-free surfaces
  • Optically measurable after grinding
  • Reduced polishing times
  • Long life-time
  • Their ability to achieve polished surfaces
  • High dimensional accuracy
  • Very clean process
  • High process repeatability
  • Low sub surface damage
