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 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.

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

Coolant filtration systems

Recycling, filtration and temperature controlled

We build efficient coolant filtration systems for processing, filtering, pumping and temperature
controlling coolants and cutting fluids. Our coolant filtration systems can be utilized in the machining of glass, ceramics and metals. They are suitable for grinding, generating, sawing and milling machines and serve as a substitute for centrifuges. The integrated water-water-chiller can be connected with the central cooling system or external cooling unit.

The combination of sedimentation and 2-phase ultra-fine filtration enables a 3-phase filtration process. dopa coolant filtration systems are further equipped with:

  • Quick couplings on all electrical connections and media lines
  • Non-contact level monitoring with alarm function (acoustic & optical)
  • Acoustic and visual alarm in case of pump errors (e.g. mechanical blockage)

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

Benefits of dopa coolant filtration systems

  • Cost effective alternative to centrifuges
  • Compact design
  • 3-phase filtration secures that particles ≥1µm are filtered out
  • Ultra-fine filtration allows usage in the production of high-end surfaces
  • Removable pump units enable very easy cleaning of the entire system
  • Significant minimization of noise and vibration in the working area

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