LbG-200B Touchscreen Low-Speed Metallographic and Petrographic Composite Sample Preparation Precision Cutting Machine (Stepless Speed Regulation)

Description

Product Introduction:

The LbG-200B touch-screen precision cutting machine for low-speed metallographic and petrographic sample preparation is ideal for slicing small, soft, brittle, or irregularly shaped specimens of metals, composite materials, plastics, electronic components, biomaterials, ceramics, cement, rocks, and minerals. It is also widely used for preparing thin-section samples. This machine employs gravity‑fed straight‑cutting with a weight‑block load and automatically stops upon completion. A micrometer adjustment mechanism allows precise control over specimen thickness. Equipped with a touch‑screen interface, it offers clear operation and adjustable diamond‑grinding wheel speeds. To prevent overheating and thermal damage during cutting, the unit features a movable coolant reservoir; as the diamond cutting wheel rotates, it carries coolant to cool both the wheel and the specimen, resulting in a bright, smooth surface free of burns.
