MP‑2B Metallographic Specimen Grinding and Polishing Machine

Product parameters:

The MP-2B Metallographic Specimen Grinding and Polishing Machine features a dual-disc design, allowing two operators to perform specimen preparation simultaneously. The rotation direction of the discs can be switched between clockwise and counter-clockwise to accommodate various operational preferences. The machine is primarily used for the pre-grinding, fine grinding, and polishing of diverse metallographic specimens; it grinds surfaces, removes deformed layers, and achieves a mirror-like finish, thereby providing high-quality specimens for subsequent metallographic microscopic examination.
Powered by a 750W brushless DC motor, the machine utilizes a multi-ribbed belt drive system for the grinding and polishing discs. It comes with standard Φ230mm discs, with Φ203mm options available upon request. A stepless speed control system allows for a speed range of 0–1500 rpm; users can freely adjust the rotation speed based on specimen material, abrasive grit size, and polishing techniques to meet the specific processing requirements of materials such as ferrous and non-ferrous metals.

The unit includes an integrated cooling water supply system that continuously cools and rinses the specimen during grinding. This effectively dissipates heat generated during the process, preventing thermal damage or burning of the metal's microstructure and ensuring the integrity of the specimen's original structure. The combination of a brushless DC motor and multi-ribbed belt drive ensures smooth operation with minimal vibration and noise. With comprehensive safety features, the machine delivers stable and reliable performance.
Operating at 220V/50Hz, the machine measures 715mm × 605mm × 260mm and weighs 50kg, featuring a robust and stable structure. It is widely used in quality control laboratories within industrial enterprises, as well as in research institutes and metallographic laboratories at colleges and universities, making it an ideal choice for specimen preparation in the field of metallographic analysis.
