Buehler VibroMet 2 | Vibratory Polisher
The VibroMet® 2 vibratory polisher is Buehler’s horizontal‑motion vibratory polishing system with a 12 in bowl designed to remove the last traces of mechanical damage and produce flat, deformation‑free surfaces suitable for EBSD and AFM analysis. Its 7200 cycles‑per‑minute horizontal oscillation maximizes specimen contact with the polishing cloth, giving exceptional flatness, minimal edge rounding and a stress‑free surface without the hazardous electrolytes required by electro‑polishers.

Key Features & Benefits of Buehler VibroMet 2
Key Features
- Horizontal vibratory motion: 7200 cycles‑per‑minute horizontal oscillation maximizes contact with the polishing cloth and naturally rotates specimens around the bowl.
- Deformation‑free surfaces: Removes minor deformation after mechanical prep, producing stress‑free, flat surfaces without electrolytes or ion milling.
- Large 12 in bowl: Generous working area supports multiple mounted specimens—ideal for batch polishing.
- Adjustable amplitude: Variable vibration amplitude with LED bar graph to tune polishing action for different materials and loads.
- Quick‑change components: PVC polishing bowl and transparent cover are easy to remove and clean; optional quick‑load holders simplify sample setup.
User Benefits
- EBSD & AFM ready: Produces surface finishes suitable for EBSD and AFM, improving pattern quality and data reliability.
- Operator‑free polishing: Once loaded and started, specimens require minimal attention, freeing staff for other tasks.
- Safer than electro‑polishing: Eliminates hazardous electrolytes and associated handling issues while achieving comparable or better surface quality.
- Excellent for mixed materials: Gentle vibratory action works well on multi‑phase and non‑homogeneous specimens that are difficult to finish mechanically.
- Compatible consumables: Designed to be used with MasterMet™ 2 colloidal silica and MicroCloth for chemo‑mechanical final polishing.

Frequently Asked Questions
VibroMet 2 is used after conventional mechanical grinding and polishing to remove the final layer of deformation and reveal a stress‑free surface ready for high‑resolution analyses like EBSD or AFM. [web:239][web:243][web:241]
The almost purely horizontal motion keeps specimens in constant contact with the cloth and naturally rotates them around the bowl, producing flatter surfaces with less edge rounding and deformation than traditional vibratory polishers. [web:239][web:240][web:243]
VibroMet 2 operates from a single‑phase 115 or 220 VAC, 50/60 Hz power supply and does not require water or compressed air connections, simplifying installation in most laboratories. [web:239][web:242][web:245]
Buehler recommends using MicroCloth or similar vibratory polishing cloths together with MasterMet 2 colloidal silica suspension to chemo‑mechanically polish specimens to EBSD‑ and AFM‑quality finishes. [web:240][web:243][web:241]
The 12 in bowl and loading fixtures allow many mounted specimens to be polished simultaneously—typically up to around 18 standard mounts, depending on size and arrangement—supporting efficient batch preparation. [web:239][web:243][web:242]
In many cases, VibroMet 2 can replace electro‑polishing by achieving comparable or better surface quality and flatness without hazardous electrolytes, simplifying safety and waste handling while improving ease of use. [web:240][web:243][web:245]
