Product Description
The HMP-1BC Fully Automatic Vacuum Grinding & Polishing Machine integrates grinding, polishing, and cleaning into a compact, automated system. It is specially equipped with a vacuum chuck and vacuum pump module, making it ideal for processing fragile and ultra-thin materials such as crystals, wafers, lenses, glass sheets, and delicate brittle samples. Using touchscreen control and a direct-drive motor, the machine provides smooth rotation, low noise, long lifespan, and reliable performance. Users can freely adjust the polishing speed based on the material, while automatic fixed-pressure control ensures uniform sample treatment. With built-in cleaning functions, overload protection, and intuitive operation, HMP-1BC is widely used in industrial laboratories, research institutes, and metallographic preparation centers.
