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 Pads

With dopa polishing pads you will achieve superior flatness, material removal rate (MRR) and surface quality on materials like glass, sapphire, silicon carbide and other ultra-hard carbides and nitrides.

The dopa GP-1 works with Silica CMP slurries as well as with diamond slurries. You will achieve the best process results when using the pad in combination with dopa polishing slurries.

Customized grooving and slurry holes available upon request

Benefits of polishing pads

  • Hohe Abtragsraten (MRR)
  • Exzellente (mit GP1, WP2-7) bzw. gute (mit BP2) Ebenheit und TTV der bearbeiteten Komponenten
  • Verbessert die Oberflächengüte und minimiert die Tiefenschädigung Ihrer Bauteile
  • Erheblich verringerte Orangenhaut und Abrundung von Kanten
  • Kompatibel mit Silizium-CMP-Suspensionen im Nanometerbereich und Diamantsuspensionen
  • Gleichbleibende Abtragsraten, welche Ihnen eine bessere Prozesskontrolle ermöglichen
  • Sehr beständiges Tuch mit langer Nutzungsdauer

WAMP Mounting Film

WAMP Films for Secure Workpiece Fixation

dopa WAMP mounting film is used to securely fix parts for single side grinding, lapping, and polishing processes on mounting plates. WAMP is a double-sided adhesive film with a thickness tolerance of only ± 0.001mm. Without preheating the base plate, it can be fast and easily applied, and the components mounted.

Several gluing, cementing, and optical contact bonding processes can be substituted with WAMP. It is primarily used to fix workpieces on mounting plates in single-side grinding, lapping, and polishing applications. The film is compatible with mounting plates made of glass, ceramic, and metal in combination with nearly all types of substrates.

Thanks to WAMP’s very high parallelism and homogeneity, it enables the production of high-precision, parallel components, reduces waxing errors, and ensures stable process results. After processing, the adhesive can be easily deactivated by heating, allowing substrates to be removed without any residue.

The WAMP mounting film has a total thickness of about 0.246 mm (delivery state) and is made of 3 different layers:

LayerDescriptionThickness
1st Layer:Protective film0.036 mm
2nd Layer:WAMP film0.174 mm
3rd Layer:Protective film0.036 mm

WAMP is available in 3 different color-coded release temperatures:

TypeRelease Temperature [°C]
Carbon-black WAMP> 50 °C
Green WAMP> 50 °C
Red WAMP> 80 °C
Purple WAMP> 100 °C

You will find all necessary details how to use WAMP in our tutorial

Benefits of WAMP

  • Easy and fast to apply
  • Precise positioning
  • No adhesive gaps or cementing failures
  • Low release temperatures
  • Fast and easy to remove without residues
    → Can be used to protected very delicate polished surfaces from scratching
    → No need for special cleaning
  • Low thickness tolerance
    → Can be used to process even very thin components (< 0.1 mm)

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
