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 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

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

Dressing & Conditioning Tools

For all our grinding tools and processes as well as our polishing pads and solutions, we are able to supply customized dressing and conditioning tools.

Please contact us for your non-committal consultation.

Benefits of dressing tools for grinding tools:

 

  • Maintains a long lifespan of the grinding tools as the binding is only removal marginally
  • Easy to use
  • No contamination with residues
  • Very quick dressing – and shape correction cycles of usually just a few seconds

Benefits of PU pad dressing & conditioning tools:

  • Extremely high lifespan
  • No scratches from abrasive diamonds or break-offs
  • Very cutting efficient and therefore ensures fast processing and easy shape correction
