1. Definition and Function of Metallographic Cutting Discs

FunctionA precision cutting tool specifically designed for metallographic sample preparation, cutting through metals, ceramics, and other materials at high speeds,Retaining the original microstructure of the sample, avoiding thermal damage or deformation.

Core Requirements:

High Cutting Precision: Ensuring a smooth cut, reducing subsequent grinding workload

Low Thermal Impact: Preventing high temperatures from altering the material's microstructure

Cleanliness: Avoiding contamination of the sample by cutting debris

2. Cutting Disc Materials and Classification

Type	Material/Structure	Applicable Scenarios	Advantages	Limitations
Resin Bond	Diamond + Resin Bonding	Hard and Brittle Materials (Glass, Hardened Steel)	Elastic cushioning, good heat dissipation, smooth cutting surface	Short lifespan, not heat resistant
Metal Bond	Diamond Abrasive + Metal Matrix	Superhard Materials (Ceramics, Titanium Alloys)	Strong wear resistance, long lifespan	Slow cutting speed

3. Key Performance Parameters

Outer Diameter and Thickness: Common outer diameters are 100-350mm, thicknesses of 0.5-3mm (thin discs for precision cutting)

Abrasive Grain Size:

Coarse Grain Size (80-120 mesh): Fast cutting, suitable for large samples

Fine Grain Size (200-400 mesh): High precision cutting, reduces subsequent polishing

Maximum Rotational Speed: Must match the rated speed of the cutting machine (usually marked as m/s or RPM)

4. Selection Guide

Choose Based on Material Hardness:

Soft Metals (Aluminum, Copper) → Silicon Carbide Cutting Discs

High Hard Materials (High-Speed Steel, Ceramics) → Diamond Cutting Discs

Choose Based on Cutting Requirements:

Routine Testing → Resin Bonding offers high cost-performance ratio

High Precision Research → Electroplated Ultra-Thin Cutting Discs

5. Usage Precautions

Coolant is Essential: Use water-based or oil-based coolants to lower temperature, preventing sample oxidation and overheating of the cutting disc

Cutting Parameters:

Feed Speed: Slow for hard materials (0.01-0.1mm/s), can be increased for soft materials

Cutting Pressure: Light and gradual, avoiding impact loads

Safety Protection: Wear safety goggles and dust masks, ensure the equipment's protective cover is intact

6. Common Problems and Solutions

Problem Phenomenon	Possible Causes	Solutions
Burning of Cutting Surface	Insufficient cooling or excessive speed	Increase coolant flow, reduce speed
Abnormal Wear of Cutting Disc	Mismatch between material and cutting disc	Replace with a cutting disc of higher hardness/bonding agent
Sample Edge Chipping	Feed speed too fast or unstable clamping	Reduce feed amount, use specialized fixtures to secure the sample
