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.

PSS-AW
PSS-WW
PSS-MAX
PSS-CUSTOM

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).

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.

CFS75L
CFS300L

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).
