Frequently Asked Questions
1. What materials can the ME31 Series PCD End Mill machine?
The ME31 Series is ideal for non-ferrous materials such as aluminum alloys,
copper, brass, graphite, and composite materials like CFRP.
2. How does the ME31 Series differ from carbide end mills?
PCD cutting edges provide 10x longer tool life, higher surface
finish, and better wear resistance compared to carbide tools, especially in
abrasive materials.
3. Can the ME31 Series be used for high-speed machining (HSM)?
Yes. The optimized flute design and PCD edge sharpness make it suitable for
high-speed and high-feed machining with excellent stability.
4. What industries commonly use the ME31 Series?
Aerospace, automotive, electronics, and composite manufacturing industries use
it for precision machining of lightweight and high-performance materials.
5. What surface finish can I expect with ME31 PCD end mills?
It can achieve mirror-like finishes, with surface roughness Ra ≤ 0.2 μm
in aluminum and graphite machining.
6. Are these tools suitable for machining silicon-containing
aluminum alloys?
Yes. The PCD edge is extremely wear-resistant, making it effective even in
high-silicon aluminum alloys.
7. How does the ME31 Series help reduce production costs?
By extending tool life, reducing tool changes, and minimizing rework due to
poor surface finish, it lowers overall machining costs.
8. Can the ME31 PCD End Mill be re-sharpened?
Yes, PCD tools can be reconditioned and re-sharpened by
specialized services, further extending their usability.
9. What spindle speeds are recommended for ME31 PCD end mills?
High spindle speeds (up to 20,000–30,000 RPM depending on machine and material)
are recommended for optimal performance.
10. What sizes and configurations are available in the ME31 Series?
The ME31 Series is available in multiple diameters and cutting edge lengths,
with both standard and custom geometries depending on application needs.
