cutting parameters for beryilium

[Millertime]

looking for cutting params for milling on beryilium with carbide end mills

[Guest SAIPEM]

Beryllium Copper (C17000)

Beryllium Copper (C17200)

Beryllium Copper (C17500)

 

Start between 500 -550 FPM and a chip load of 0.005 per flute to start.

 

This will be a safe starting place depending upon your specific application.

You asked Beryllium or Be-Cu?

[mchin-pilot]

MUST be aware of the safety procedures needed. Its inhalation is toxic. Never air blow the chips/dust. Better be aware first.

[Guest SAIPEM]

Unless you work in a foundry where actual Beryllium is made, you don't need to be overly concerned.

 

BeCu is safe to handle and machine.

Standard machining practices are not dangerous.

Using any type of coolant further increases safety.

 

GRINDING is the primary concern.

It should never be done dry.

If you are going to drill this stuff low helix twist drills help a lot with breaking this gummy material.
