The grinding and polishing head Rubin 500 is very easy to operate, while the Rubin 520 meets the highest standards with its innovative touchscreen operation and modern safety concept. The possibility to apply single and central pressure is standard for both machines.

The dosing unit Topas 130 is suitable for all machines without integrated dosage (Saphir 550/560). Saphir 550 may be equipped with the parallel grinding unit Rubin 540. Pressure-sensitive samples are only pressed down by their own weight.

The vibratory polishing device Saphir Vibro is designed for the preparation of specimen surfaces practically without deformation. This preparation method is especially suited for further characterizations like EBSD (electron backscatter diffraction), nano indentation using AFM (atomic force microscopy) or micro hardness testing.

Due to the very gentle removal of material it is applicable especially for soft and ductile materials, like titanium-aluminum, pure copper and copper alloys, aluminum alloys, soft steel, and nickel-based alloys.

Having a diameter of Ø=308mm, the large bowl provides sufficient space for polishing of a complete sample holder, large specimens or for the simultaneous polishing of up to 21 mounted specimens. The bowl is equipped with a double magnetic system. It allows to fix, remove and clean both the bowl or polishing cloth very quickly, without any tools or other fixings. Polishing cloths suited for magnetic system with a diameter of 300mm or 305mm (12”) can be used.

Key features

  • Rapid changeable polishing bowl with magnetic system
  • Surface-Guard: reduces crystallization and corrosion of the specimen surface
  • Automatic frequency control from 60-120 Hz, e.g. for mass variation
  • Intuitive user interface and touch screen
  • Pre-installed preparation methods and consumable list
  • Low-noise operation, almost indefinite polishing time without supervision
  • Exhaust connection plug (exhaust connection for enhanced user-friendliness and safety)
  • Up to 200 custom preparation methods can be saved
