CM-250F The precision flatbed cutting machine uses a touch screen and PLC control, with stable performance and real-time display of cutting parameters. It features automatic Y-axis feed cutting, high positioning accuracy, a wide speed adjustment range, and strong cutting capabilities. The cutting chamber adopts a fully enclosed structure, with a transparent protective cover for observation during cutting. Equipped with a circulating cooling system, the surface of the cut specimen is bright, flat, and burn-free. It is particularly suitable for precision cutting of materials such as PCB boards, electronic components, ceramic materials, crystals, carbide, rocks, concrete, organic materials, and biological materials (teeth, bones), making it an ideal choice for desktop automatic precision cutting.
Product features:
1. The automatic cutting machine is controlled by PLC and touch screen, with very high reliability and powerful control capability.
2. The machine is equipped with a fully enclosed structure, operation is very safe.
3. The machine uses a high-torque, high-power servo motor and an infinitely variable speed control system for high and stable working efficiency.
4. With a large, transparent cutting chamber for visual observation of the cutting process and ease of use, this is a high quality precision cutting machine suitable for research institutes and companies.
5. Touch screen programmable control, with automatic cutting function to reduce operator fatigue and ensure consistent specimen cutting.

Metallographic Cutting Wheel Selection Guide:
Material Category | Examples | Recommended Cutting Wheel | Notes |
High-hardness, tough materials | Hardened steel, high-speed steel, tool steel, stainless steel, titanium alloys | Red wheel (Single Crystal Alumina + Red Resin Bond) | High wear resistance, sharp cutting, smooth surface, minimal heat-affected zone |
Medium-hardness steels | Carbon steel, alloy structural steel, low-alloy steels | Red wheel preferred | Ensures smooth cutting surface, prevents metallographic changes |
Brittle materials | Cast iron, ceramics, glass, hard alloys (carbides) | Black wheel (White Alumina + Black Resin Bond) | High efficiency, low heat generation, reduces cracking risk |
Non-ferrous metals | Aluminum, copper and alloys, brass, bronze | Black wheel (White Alumina) | Less heat, prevents sticking, clean cut |
High-purity / soft metals | Oxygen-free copper, pure aluminum, magnesium alloys | Black wheel | Low heat, clean and precise cut |
Summary:
Red wheel → Best for hard steels, tool steels, stainless steels, and other tough materials.
Black wheel → Best for brittle materials (cast iron, ceramics) and non-ferrous metals (copper, aluminum, etc.).
