VibroMet^® 3 Vibratory Polisher

VibroMet 3

Vibratory Polisher for Final Metallographic Surface Finish

The VibroMet 3 vibratory polisher, with a large, 11.25in [285mm] working surface for multiple samples, is designed to prepare high quality polished surfaces for a wide variety of applications, including EBSD and AFM analysis. The horizontal oscillation removes minor deformations, yielding an exceptional surface. Add this after your initial polishing and grinding steps to take your polishing to another level.

Why Choose the VibroMet 3 Vibratory Polishing for your Final Surface Preparation?

Vibratory polishing is able to remove minor deformation left over from conventional polishing steps
Its high quality polish makes it ideal for Electron Back-Scatter Diffraction (EBSD) and Atomic Force Microscopy (AFM)
You can protect your samples from oxidation or crystallization with our new end cycle options: ON, OFF or PULSE
Reduce training and increase consistency by saving polishing methods (up to 6)
Spend less time cleaning, cleaning time has been reduced by more than half.

Frequently Asked Questions

General Questions

What is a vibratory polisher?

Equipment that utilizes vibration between the sample surface, polishing suspension and polishing cloth to gently remove material from a leveled sample surface.

What Are the Benefits of Vibratory Polishing?

Vibratory polishing yields a higher quality surface finish than traditional grinding and polishing equipment.

Why Choose Vibratory Polishing for Final Surface Preparation?

Surface quality requirements vary depending on the analysis method or the magnification of the images being captured. Traditional mechanical polishing may appear scratch-free but can leave surface deformation. Some analyses – such as EBSD and color etching – require an extremely low deformation finish. Vibratory polishing can prepare samples to a level where scratches and deformation, sometimes left behind by traditional polishing methods, are no longer present.

How does a vibratory polisher work?

Vibratory polishing utilizes rapid, oscillating horizontal movements to gently remove material from sample surfaces. These movements remove deformation from previous polishing cycles, resulting in an even higher-quality surface finish.

What are the advantages of vibratory polishing compared to electropolishing?

Electropolishing can lead to excess rounding at feature boundaries due to preferential polishing, as well as uneven removal if used for excess times. Vibratory polishing maintains surface flatness, even with mixed material samples or longer polishing times.

When should I use vibratory polishing instead of conventional polishing?

Vibratory polishers are not used instead of conventional polishers; they are used in addition to conventional polishing machines when a higher quality surface finish is needed.

Why is vibratory polishing used in metallography?

Vibratory polishing is used in metallography to remove remnant scratches or deformation, producing a higher-quality surface finish.

What materials can be polished using a vibratory polisher?

Any material that can be mechanically ground and polished can also be polished in a vibratory polisher.

Can a vibratory polisher be used for EBSD sample preparation?

Yes. We recommend that vibratory polishing be performed on samples after conventional polishing if EBSD analysis is the method of analysis. This article contains preparation methods for multiple material types.

How long does vibratory polishing take?

Cycles can range from half an hour to multiple hours, depending primarily on start condition and sample material.

Can you polish samples that aren't mounted?

Yes, unmounted samples can be polished in a vibratory polisher.

Consumable and Accessory Questions

What consumables are used with a vibratory polishing machine?

Polishing cloths and suspensions are required for the VibroMet 3.

What accesories are used with a vibratory polishing machine?

A loading fixture, specimen holders, and specimen weights are recommended accessories when working with mounted samples. To further improve your cleaning process, we also recommend using carrier plates. Carrier plates make it significantly easier to remove the polishing cloth.

What polishing cloths work best in a vibratory polisher?

Napped cloths such as Microcloth or MasterTex are typically recommended.

What polishing suspensions should be used with a vibratory polisher?

Use the same suspension as your final polishing step.

Equipment Questions

What is the difference between a vibratory polisher and a grinder polisher?

Vibratory polishers are much less aggressive in material removal than a grinder polisher. They are typically used for final polishing only, unlike mechanical grinder-polisher machines that are used for planarizing and rapid material removal, as well as mechanical polishing. The gentler polishing action of the vibratory polisher removes surface deformation that is unavoidable using conventional polishing.

Can a vibratory polisher replace a grinding and polishing machine?

No, we recommend using a vibratory polisher after the final steps of using a grinding and polishing machine.

Is vibratory polishing suitable for automated laboratories?

Yes, as this is a semi-automatic vibration polishing system, it would fit in perfectly with other automated polishers.

Buying Questions

What is the sample capacity of the VibroMet 3?

The VibroMet 3 uses 12inch [305 mm] diameter cloths, and has a circular usable area of about 11.25inch [285 mm].
