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

WAMP Mounting Film

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 foil with a thickness tolerance of only about ± 1μm. Without preheating the base plate, it can be fast and easily applied and the components mounted.

Several glueing, cementing and optical contact bonding processes can be substituted with WAMP. It is compatible with glass, ceramic and metal base plates and nearly all types of substrates.

Thanks to the WAMP’s very high parallelism and homogeneity, you can produce very parallel parts, cut down the waxing error and have a stable process. 

The WAMP mounting film has a 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)

Diamond Slurry

Diamond slurry for highest surface qualities and excellent MRR

Our diamond slurries are used for polishing various materials, have supreme lubrication properties and do not dry. The diamond particles are excellently dispersed and produce very homogeneous surfaces. In our special formulations the abrasive particles are stabilized to prevent them from settling. This guarantees a highly efficient process.

The diamond grain used in our slurries complies with highest quality standards – from coarse grain sizes for diamond lapping to 0.010 µm nano-diamond slurries for ultra-fine polishing.

Our portfolio of diamond slurries caters for various application:

Typ OSP

For polishing optical glass and crystals on polishing pads, pitch and dopa’s solid polishing pads.

Typ LLCP+

For lapping and polishing of ceramics and ultra-hard materials such as Sapphire, Carbides, Nitrides and Spinel on dopa’s solid polishing pads.

Typ PMC

For fine-polishing of ceramics and ultra-hard materials such as Sapphire, Carbides, Nitrides, Spinel and metals on dopa polishing wheels and pellets.

More

We also offer slurries for polishing metals, ceramics and other brittle materials as well as ultra-fine colloidal polishing slurries.
