DiaUltra is our best performing 2-in-1 diamond suspension. High-quality synthetic diamonds, a unique lubrication system, carefully selected suspending agents and numerous tests have resulted in the best diamond suspension ever!
- More than 25% higher removal rates than the best competing diamond suspension.
- Fastest preparation times and substantial consumable savings.
- Best quality surface finish for shorter following preparation steps.
Who should use DiaUltra?
With DiaUltra, you do not need a specific suspension for every fine-grinding disc or polishing cloth. Our unique formulation allows us to have only one suspension per grain size. DiaUltra can be used for all materials, both soft and hard, where other suspensions have two different versions.
Technical Information
Highest Removal Rates
We have succeeded in developing a formulation with a very high removal rate by modifying and exchanging some of the key ingredients from our 2-in-1 suspension DiaMaxx. At the same time we have managed to keep the same high quality surface finish that we are used to from DiaMaxx. The combination of an extremely high removal rate and perfect surface finish allows us to reduce the preparation time remarkably with DiaUltra.
Fastest Preparation Times
The removal rate measurements show that DiaUltra outperforms competing suspensions by far. However, we also wanted to document that these figures actually will result in a measurable advantage for our customers. Therefore, we have used DiaUltra to re-run some of our Aka-Brief preparation methods. This was done to compare the preparation times both against our own methods, but also against the equivalent methods from our competitors.
The conclusion is that the preparation times are clearly reduced when using DiaUltra. Both the fine grinding step and the diamond polishing steps are up to 40% shorter.
Aka-Brief preparation method with DiaMaxx Poly:
| Preparation of Surface Hardened Steel | |||||
| 1 | Piatto #220 | Water | 300 rpm | 35 N | Until plane |
| 2 | Allegran 3 | DiaMaxx Poly 9 μm | 150 rpm | 35 N | 4:00 min |
| 3 | Ramda | DiaMaxx Poly 3 μm | 150 rpm | 30 N | 3:00min |
| 4 | Napal | DiaMaxx Poly 1 μm | 150 rpm | 20 N | 1:00 min |
| The parameters in the preparation method are based on 300 mm dia. disc size and 30 mm dia. individual samples | |||||
Aka-Brief preparation method with DiaUltra: Steps 2, 3 and 4 have been reduced with almost 40%:

| 3 | Ramda | DiaUltra 3 μm | 150 rpm | 30 N | 2:00min |
| 4 | Napal | DiaUltra 1 μm | 150 rpm | 20 N | 0:30 min |

As you can see from the comparison above, our new Aka-Brief preparation method with DiaUltra is already much faster than the previous Aka-Brief method with DiaMaxx. When comparing the method with DiaUltra to competitive methods our preparation time is less than half. This reduction not only saves important time, it will also provide a tremendous saving in consumables.
With half the preparation time, you only use half the amount of diamond suspension. Your polishing cloth will probably last for the same length of time (in minutes), thus allowing for many more samples to be prepared on the same cloth, again reducing the actual cost per prepared sample.
In production/quality control, time is usually an important factor. The faster the result is ready, the sooner the production can either continue or be corrected if necessary. As production cost can be very high, time savings are often much more important than savings in consumables. With DiaUltra you will reduce both preparation time and consumable cost.
Best Surface Finish and Quality
It is difficult, if not impossible to examine and characterise scratches after a preparation step under an optical microscope. To be able to quantify the scratches and compare different preparation steps and suspensions we are using our AFM (Atomic Force Microscope). As you can see from the image below, you do not only get a very clear image at a high magnification, you also get a measurement of the scratch depth. This makes it possible to compare different suspension formulations and in combination with the removal rate measurements find the formulation that produces the fastest and best result.
This image combines three different scans after 9, 6 and 3 µm preparation steps with DiaUltra respectively. It clearly shows how the surface gets finer and finer with shallower scratches after each step.
