HMP-2B/BZ Automatic Metallographic Sample Grinding & Polishing Machine

Product Description

The HMP-2B/BZ Automatic Metallographic Sample Grinding & Polishing Machine is designed for efficient and repeatable preparation of metallographic specimens. It combines grinding, polishing and cleaning functions in one compact dual-disc platform. Both models feature variable-speed grinding discs, high-torque drive motors and a user-friendly control interface for precise process adjustment.

The HMP-2B model uses mechanical pressure and manual head lifting, making it suitable for flexible laboratory use. The HMP-2BZ model adds automatic head lifting and electronic pressure control with single-point and central pneumatic loading, which enhances automation and consistency for high-throughput environments. Together, the two configurations cover a wide range of application needs in laboratories, quality control departments and research centers.

Product Advantages

• Dual-disc structure allows two working positions, improving efficiency.

• Variable-speed discs support fine grinding and polishing steps.

• Four selectable fixed speeds simplify common process setups.

• Forward and reverse disc rotation improves cutting action and surface finish.

• Direct-drive motor design provides smooth operation and low noise.

• Rigid base and housing minimize vibration and ensure stable polishing.

• Built-in water supply and drainage help maintain a clean working surface.

• Compatible with a wide range of abrasive papers and polishing cloths.

• Timing function supports repeatable and standardized preparation cycles.

• Emergency stop button improves operational safety.

Differences Between HMP-2B and HMP-2BZ

• HMP-2B head locking is manual, while HMP-2BZ head locking is fully automatic, improving convenience and safety.

Application

The HMP-2B/BZ series is suitable for metallographic sample preparation in:

• Materials laboratories and research institutes

• University teaching laboratories

• Industrial quality inspection and production plants

• Heat treatment, casting and metalworking facilities

It can be used for grinding and polishing steels, alloys, cast irons, non-ferrous metals, coatings and other metallic materials requiring metallographic examination.
