Polishing Slurry

Superior surface finish of optical components

We produce polishing slurries for the surface finishing of various materials. By using these slurries in your polishing process, you will achieve superior flatness, material removal rate and surface quality.

These slurries with evenly dispersed grit are very stable and offer a long-time use.

Typ XC-7

Colloidal silica polishing slurry for polishing of materials such as sapphire, silicon, YAG and calcium fluoride.
Particle size: 7 – 10 nm

Typ XC-35 / XC-40

Colloidal silica polishing slurry for polishing materials such as sapphire, silicon, YAG and calcium fluoride.
Particle size: XC-35: 50 nm
Particle size: XC-40: 90 nm

Typ PMI-2

Polishing slurry made of rare earths (Ce) for the surface finishing of glass.

Other types

We also produce other slurries for materials such as sapphire, silicon carbide and other ultra-hard carbides and nitrides. We would be pleased to determine the right solution for your needs.

Benefits of dopa polishing slurries

  • Gives a perfect surface finish and eliminates any subsurface damage of your parts
  • High material removal rate (MRR)
  • Excellent part flatness and TTV of your parts
  • Compatible with all common hard and medium-hard PU-pads and suede-type polishing pads.
  • Keeps the removal rate stable to ensure better process control
  • Stable slurry with long lifetime

Polishing Slurry Systems

High Precision Supply and Temperature Control

We build efficient systems for high precision supply and temperature control of polishing slurries and suspensions. These can be utilized in the area of high precision machining and are suitable for polishing machines or other machines that require precision temperature-controlled fluid feed or applications where you want to recycle fluids.

dopa polishing slurry systems have electronic temperature control, quick couplings on all electrical connections and media lines as well as different chilling options:

  • Water-Water-Chiller (WW) for connection to central cooling system or external cooling unit
  • Self-chilling stand-alone unit with integrated Air-Water-Chiller (AW)

Various further options are available upon request. We build polishing slurry systems according to your needs. Please contact us to discuss your specifications.

Benefits of dopa polishing slurry systems

  • Compact design
  • Heating and cooling through outer tank walls prevent incrustations and agglomeration of polishing powders
  • Enables finer and more consistent polishing grades
  • Minimization of media-contacting components
  • High precision temperature control
  • Smooth surfaces without corners and edges enable easy cleaning of the entire system from the inside and outside

Please see the data sheet – dopa polishing slurry systems to access the detailed machine description (PDF).

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

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
