Diamond Powder

High-purity diamond powders

We produce high-purity diamond powders for outstanding material removal rates and best surface finishes. Our natural and synthetic diamond powder is characterized by its high purity and homogeneity.

This guarantees remarkable cut rates, process stability and ultra-fine surfaces.

Short lead times and very good value for money

We have most of our powders on stock to ensure short lead times. The mostly commonly used grit sizes are listed below. Grits with special grading, shape and hardness are available upon request. We also offer our diamond powders as ready-to-use diamond slurries.

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 Pads

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.

Table: Overview polishing pads

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

Tutorial WAMP (english)

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)
