Why Use a Manual Grinding Machine?

Proper specimen preparation is essential for obtaining accurate compression test results. Uneven or non-parallel surfaces can significantly affect load distribution and reduce testing reliability.

The BESMAK Manual Grinding Machine ensures:

• Accurate specimen surface preparation
• Excellent flatness and parallelism
• Consistent compression testing results
• Faster preparation compared to capping methods
• Reduced laboratory operating costs
• Safer and cleaner working environment

Key Features of Manual Grinding Machine

Precision Diamond Grinding Wheel

The machine is supplied with a high-quality diamond grinding wheel that provides smooth, accurate, and repeatable grinding results.

Excellent Surface Flatness

The maximum flatness tolerance on compression test specimen surfaces is:

• 0.050 mm for concrete specimens
• 0.5° perpendicularity tolerance for core samples

This ensures compliance with international testing requirements.

Safe and Ergonomic Design

The ergonomic design minimizes operator exposure to water, dust, and debris while allowing easy access to water inlet and outlet systems.

Corrosion Resistant Construction

All steel components are electrostatically painted to prevent corrosion caused by water and cementitious materials.

Waterproof Electrical Protection

The ON-OFF switch is protected by a waterproof enclosure for safer operation in laboratory environments.
