L.T Graphite, based on years of research and feedback from final customers, specially design and produced for EDM machining mateials, with characteristics:
1) The average particle sizes of the material
The average particle sizes of the material directly affects the discharge condition of the material. The smaller the average particle size of the graphite material, the more uniform the discharge of the material, the more stable the discharge condition, the better the surface quality, and the smaller the loss; the larger the average particle size, the better the removal rate in rough machining, However, the finishing surface effect is poor, and the electrode loss is relatively large.
2) The flexural strength of the material
The flexural strength of a material is a direct reflection of the strength of the material, showing the tightness of the internal structure of the material. High-strength materials have relatively good discharge wear resistance. For electrodes that require high precision, materials with better strength should be selected as much as possible.
3) Shore hardness of the material
The hardness of graphite is higher than that of metal materials, and the loss of tools during cutting is greater than that of cutting metals. At the same time, graphite materials with high hardness are better in controlling discharge loss.
4) The intrinsic resistivity of the material
The graphite material with higher intrinsic resistivity will discharge slower than the one with lower resistivity. The higher the intrinsic resistivity, the smaller the electrode loss, but when the intrinsic resistivity is too high, the discharge stability will be affected.
