SAPHIR 560 / RUBIN 520
The QATM SAPHIR 560 with the motor-driven RUBIN 520 head is a twin-wheel metallographic grinder-polisher — two independent wheels let you grind on one and polish on the other, preparing 1–6 mounted samples per run with automatic material-removal measurement for deformation-free surfaces.
- ✔ Twin Ø 200–300 mm wheels · single force 5–100 N or central force via holder
- ✔ Automatic material-removal measurement to 0.01 mm · touch-screen stored methods
- ✔ Lead time: 4–8 weeks — configured to order · install & training included
What your metallography lab actually checks
Two wheels, one footprint
Two independent Ø 200–300 mm wheels, each on its own 0.75 kW drive, let you grind on one and polish on the other without swapping discs — roughly doubling throughput in a single bench. The RUBIN 520 head still applies individual force per sample and measures removal to 0.01 mm for repeatable, deformation-free surfaces.
A materialography engineer on the line
Wheel size, sample holders and preparation methods matched to your material mix by engineers who run metallographic prep in-house at Additive Plus. Sub-4h reply, NDA standard.
SAPHIR 560 with RUBIN 520 is a twin-wheel metallographic grinder-polisher with a motor-driven grinding and polishing head — two independent working wheels let you grind on one and polish on the other, preparing 1–6 mounted samples per run for reproducible, deformation-free surfaces ready for hardness testing and microscopy.

Why metallography labs choose the SAPHIR 560
Two wheels double the prep chain in one footprint — and the RUBIN 520 head takes operator variation out of every reading.
Twin working wheels
Two Ø 200–300 mm wheels driven by 2× 0.75 kW motors — grind on one, polish on the other without swapping discs, so throughput roughly doubles versus a single-wheel bench.
Single and central pressure
Single force 5–100 N per sample, or central force through the holder — mix diameters and materials in one run without re-clamping.
Automatic removal measurement
Set a target removal; the machine measures material removed automatically to 0.01 mm and switches off when the preset value is reached.
Touch control, memory, safety
Programmable methods on a touch display with password protection per program. Preparation starts only with the front cover extended; the basin is LED-lit.
How Additive Plus supplies the SAPHIR 560
A grinder-polisher is only as good as the method behind it — we set both up together.
Configure to your lab
Working-wheel diameter (Ø 200–300 mm), sample-holder set, and RUBIN 520 head matched to your throughput and material mix.
Install and train
Delivered, levelled and connected to water; your operators are trained on force, speed and removal settings so results are repeatable from day one.
Validated methods and consumables
We hand over saved preparation programs plus matched discs, cloths and suspensions — reorder without re-developing the method.
Grinding and polishing performance
Two independent working wheels run at 50–600 rpm while the RUBIN 520 head applies individual pressure to each sample at 30–150 rpm with clockwise/counter-clockwise rotation, so specimens of different diameter and material reach the same surface in a single run. The head carries a memory function for side and height setting and a quick-change function for sample holders. Integrated basin rinsing cools the working wheels and cleans the basin throughout the cycle. See the full specifications tab below for connection power, drive ratings and dimensions.

Typical applications
Wherever a defensible hardness reading or micrograph starts with a clean, flat, deformation-free surface — at higher throughput.
