Product Description
The M-1 Metallographic Specimen Pre-Grinding Machine is designed for the initial grinding process during metallographic specimen preparation. Pre-grinding is a critical step in revealing the true microstructure of a metal sample, ensuring the specimen surface is flat, smooth, and suitable for subsequent fine grinding and polishing. The M-1 model achieves uniform material removal with stable rotation, enabling users to obtain high-quality surfaces efficiently. Its enclosed grinding chamber, durable construction, and anti-corrosion water supply system ensure consistent performance in daily laboratory use. This machine is ideal for materials laboratories, metallurgical research centers, and industrial quality control departments.

Product Advantages
The main body adopts an integral ABS housing, offering impact resistance, improved durability, and excellent structural stability. This reduces vibration during operation and enhances grinding precision.
The water supply system uses stainless-steel components with superior corrosion resistance, ensuring stable cooling and continuous flushing to avoid specimen overheating.
With a 450 rpm grinding speed, the machine provides a balanced rate of material removal suitable for most metals and alloys used in metallographic analysis.
Application Range
This pre-grinding machine is suitable for educational labs, metallurgical analysis centers, research institutes, metal manufacturing plants, and industrial quality-inspection departments where reliable specimen preparation is required.
