Diamond Slurry

Diamond slurry for highest surface qualities and excellent MRR

Our diamond slurries are used for polishing various materials, have supreme lubrication properties and do not dry. The diamond particles are excellently dispersed and produce very homogeneous surfaces. In our special formulations the abrasive particles are stabilized to prevent them from settling. This guarantees a highly efficient process.

The diamond grain used in our slurries complies with highest quality standards – from coarse grain sizes for diamond lapping to 0.010 µm nano-diamond slurries for ultra-fine polishing.

Our portfolio of diamond slurries caters for various application:

Typ OSP

For polishing optical glass and crystals on polishing pads, pitch and dopa’s solid polishing pads.

Typ LLCP+

For lapping and polishing of ceramics and ultra-hard materials such as Sapphire, Carbides, Nitrides and Spinel on dopa’s solid polishing pads.

Typ PMC

For fine-polishing of ceramics and ultra-hard materials such as Sapphire, Carbides, Nitrides, Spinel and metals on dopa polishing wheels and pellets.

We also offer slurries for polishing metals, ceramics and other brittle materials as well as ultra-fine colloidal polishing slurries.

Grinding Wheels

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.

Polishing Wheels

Polishing Wheels

We produce polishing wheels for single- and double-sided machines as well as CNC tools, which can be customized to your machine and application requirements.

Our polishing wheels perform at polishing a number of different materials. Here is a collection of some of them:

  • Metals – e.g. tungsten, molybdenum, nickel silver, stainless steel, ferrites or different alloys
  • Ceramics – e.g. Spinel, Al2O3, silicon carbide, SiSiC, silicon nitride, ALON®, aluminum nitride
  • Crystals – e.g. sapphire, calcium fluoride, germanium, silicon carbide, silicon, YAG
  • Different optical and industrial glass types
  • Material or workpiece combinations of the above mentions such as sapphire in stainless steel

All our tools are ground in with high precision and customized according to your needs.
Please contact us to discuss your specification.

Benefits of dopa polishing wheels:

  • High removal rates
  • Homogeneous, scratch-free surfaces
  • Transparent, interferometrically measurable surfaces
  • Polishing of material combinations without grit boundary effects as e.g. orange peel
  • Very low sub surface damage
  • Cutting-edge technology that is continuously optimized
  • Low edge roll enables tight form errors up to the edge of the processed parts
  • Easy to dress and condition
