Description

Product Introduction:

　The purpose of this machine is to achieve the required surface finish for testing by subjecting the specimen to high-frequency vibration, which induces a minute abrasive‑polishing action. This machining method minimizes specimen wear and operates as a slow‑speed process. The machine is equipped with fixtures that can hold specimens of various sizes and shapes, and its vibration amplitude can be adjusted according to the specimen’s weight, enabling different polishing outcomes.

Vibratory polishing is widely used for the preparatory sample preparation prior to EBSD (backscattered electron diffraction), AFM (atomic force microscopy), SEM (scanning electron microscopy) analyses, and nanoindentation or microhardness testing.

Product Advantages:

1. Intelligent variable-frequency control allows for real-time adjustment of frequency and power, enabling fine-tuning to achieve superior surface polishing tailored to the material’s properties and visual characteristics. Operated via a graphical touchscreen with an intuitive human–machine interface.

2. Fully automated polishing that requires no operator intervention, with adjustable run times, enabling unattended, fully automatic operation. This enhances workforce productivity and reduces operational costs for the enterprise.

3. High-strength fiberglass-reinforced plastic housing, corrosion-resistant and impact-proof. A transparent dust cover ensures the polishing disc remains clean.

4. It can accommodate mounted specimens or larger specimens that do not require mounting.

5. Sample holders of various specifications: available in sizes from 25 mm to 50 mm; custom specifications can be provided upon request.

6. Large polishing tank, 300 mm, designed for polishing large specimens or fixture‑mounted samples; it can simultaneously polish up to 10 specimens.

7. Featuring low-noise operation and a polished‑time timer setting, it can run unattended.
