PRESI VIBROTECH 300 – Atomic-Level Surface Perfection through Vibratory Polishing

The PRESI VIBROTECH 300 is a state-of-the-art vibratory polishing machine specifically engineered for final surface preparation in metallography and materials science. It is the ultimate solution for samples requiring an absolutely deformation-free and stress-relieved finish for high-end analytical techniques such as EBSD, AFM, or microhardness testing.

Unlike traditional mechanical polishing, the VIBROTECH 300 utilizes high-frequency vibrations. This gentle process eliminates minute surface stresses and deformation layers (smearing) that can occur with conventional methods. The result is a perfectly prepared surface of unsurpassed quality, revealing the true microstructure of the material.

Key Features & Benefits:

• Ultimate Surface Integrity: Ideal for soft, ductile, or multi-phase materials where conventional polishing would cause relief effects or inclusions.
• Fully Automated Final Polishing: Once configured, the machine operates independently, allowing laboratory personnel to focus on other tasks.
• Precision Frequency & Amplitude Control: The electronic control system allows for fine-tuning of the vibration intensity to suit the specific hardness and sensitivity of each material.
• Large Capacity: The Ø 300 mm polishing bowl accommodates multiple samples simultaneously, significantly increasing laboratory throughput.
• Integrated Timer: Enables exact programming of the polishing duration for maximum reproducibility across sample batches.
• Durable & Chemically Resistant Design: The polishing bowl is easily interchangeable and resistant to common polishing suspensions.

Technical Specifications at a Glance:

• Bowl Diameter: Ø 300 mm.
• Drive System: Magnetic oscillating drive for high-frequency vibrations.
• Control Interface: Digital display for setting frequency, amplitude, and polishing time.
• Sample Loading: Suitable for individual samples of various geometries using specialized additional weights.
• Noise Level: Extremely quiet operation, ideal for continuous use in a professional laboratory environment.

Areas of Application:

The VIBROTECH 300 is indispensable for the semiconductor industry, aerospace engineering, and academic research. It is primarily used to prepare samples for EBSD (Electron Backscatter Diffraction) analysis, Atomic Force Microscopy (AFM), and the study of reactive metals such as titanium, aluminum, or precious metals.
