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

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.

Tabelle: Übersicht Poliertücher

Customized grooving and slurry holes available upon request.

Benefits of polishing pads

  • High material removal rate (MRR)
  • Excellent (with GP1, WP2-7) /good (with BP2) part flatness and TTV
  • Improves the surface finish and the subsurface damage of your parts
  • Minimizes edge-rounding and orange-peel
  • Keeps the removal rate stable giving you better process control
  • Very durable pad with long lifetime

Flatness & Gap Measuring Systems

Flatness Measurement System

T dopa flatness measuring systems are used to check the flatness of grinding wheels, lapping wheels and polishing pads on micron level. They are very easy to handle and gives you precise information about flatness over the whole diameter. Keeping your wheels and polishing tools flat is crucial for producing flat parts. Knowing the exact shape of your tools is an absolute requirement before making any adjustments. Applying the dopa FMS will improve and stabilize your processes, save cost and enable you producing better parts.

Product content:
1 x precision liner made of stainless steel
2 x precision cylinder made of stainless steel (support for the steel liner)
1 x indicator with stainless steel base (resolution of 2 µm) 1 x calibration protocol of your flatness system

All components are stored in protective boxes to protect the flatness measuring system from environmental influences and physical damage.

Parallelism/Gap Measurement System

The dopa parallelism measuring system can be used on double-side grinding-, lapping- and polishing equipment. It gives you information about parallelism of top and bottom plate as well as waviness over the complete plate diameter with a precision on micron level.

A check is necessary:
1. When grinding-, lapping- or polishing wheels have been changed
2. After sharpening and conditioning process
3. For regular system checks e.g. as part of your preventive maintenance system

Product content:
3 x precision cylinder made from stainless steel (spacer)
1 x indicator with stainless steel base (resolution of 2 µm)

To protect the parallelism measuring system from environmental influences and physical damage all components are stored in protective boxes.

When you keep flatness and parallelism on a good level you will receive a better TTV and better surface quality of your products. Additionally, you save consumables, cost and time.

We recommend you to use the dopa parallelism system together with the dopa flatness measuring system, which is a very easy way to check the flatness of the lower plate. Using both systems you get an even better process control over your equipment and you can ensure reproducible and efficient results of your manufacturing process.
