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

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

Coolants & Lubricants

Coolants & lubricants for effective grinding

The coolants and lubricants we produce are tuned and concerted with our tools. Using our coolants increases their stock removal rates and secures their consistent performance.

Our coolants simultaneously improve the surface finish on the processed parts, which subsequently cuts down polishing time.

Coolants & Lubricants

PP-1

dopa PP-1 is a highly efficient cooling and lubricating concentrate. It is ready for use, just after dilution with clean water.

PP-1 ensures high removal rates as well as excellent heat transfer and cooling properties directly in the cutting zone. Due to its chemical composition the residue of the removed material is bound instantly and taken away via your cascade/centrifuge/filter. It enables you to achieve top level surface quality on several materials such as glass, ceramics, metal and secure a long lifetime of your tools.

SZ-51

This cooling and lubricating fluid has been developed especially for processing sapphire. It is to be diluted in a higher ratio with water and is used for ultra-hard materials such as sapphire.

Benefits of coolants & lubricants:

  • Excellent water solubility
  • Clear fluid with very mild inherent odor
  • Contains defoamer
  • Outstanding usage duration during the grinding process
  • Excellent cooling properties for enhanced process control
  • Ensures an exceptionally high cutting capacity, which helps you to save time and money

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
