rp graphite electrodes with nipples

Selection of rp graphite electrodes with nipples materials for EDM

Selection of rp graphite electrodes with nipples materials for EDM. For graphite materials, the following four indicators directly determine the performance of the material:

1. The average particle diameter of the material The average particle diameter of the material directly affects the discharge status 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, a better removal rate can be obtained in rough machining, but fine machining The surface effect is poor, and the loss of rp graphite electrodes with nipples is large.

2. The flexural strength of the material The flexural strength of the material is a direct manifestation of the strength of the material, showing the tightness of the internal structure of the material. High-strength materials have relatively good discharge loss resistance. For rp graphite electrodes with nipples that require high precision, choose materials with better strength as much as possible.

3. Shore hardness of the material The hardness of graphite is higher than that of metal materials, and the tool loss during cutting is larger than that of metal. At the same time, graphite materials with high hardness have better control of discharge loss.

4. Inherent resistivity of materials Graphite materials with larger intrinsic resistivity will have a slower discharge rate than those with lower resistivity. The higher the intrinsic resistivity, the smaller the loss of rp graphite electrodes with nipples, but when the intrinsic resistivity is high, the stability of discharge will be affected. At present, different suppliers of world-renowned graphite suppliers have many different grades of graphite to choose from. Graphite materials are usually classified according to the average particle diameter. Those with a particle diameter ≤ φ4 μm are defined as fine graphite, particles with a particle diameter of φ5~φ10 μm are defined as medium graphite, and particles above 10 μm are defined as coarse graphite. The smaller the particle diameter, the more expensive the material, and the appropriate graphite material can be selected according to the requirements and cost of EDM.
