Product Description
The HMP-2A Double-Disc Automatic Grinding And Polishing Machine integrates grinding, polishing, and preparation into a single fully automatic dual-disc system. It uses a high-resolution touch interface, direct-drive brushless motors for stable torque output, low vibration, quiet operation, and high durability. Users can freely adjust disc speed, pressure mode, rotation direction, and timing parameters to match different metallographic preparation tasks. With intelligent coolant control, safety interlocks, automatic water inlet/outlet, and emergency stop, the system delivers consistent, repeatable sample quality suitable for laboratories, universities, and industrial material analysis centers.
