Hello

In our company we have the following problem:
Our aluminium alloy parts are coated and when processing the plane surface, the lacquer chips.!?

We have already tried ganging and counter rotation .
And it costs time to rough and then finish afterwards.
We use a cutter heads from Mapal or Hohlfelder with 8 to 12 teeth. Did not do anything.
With the average speed -> we have already tried everything too, at least technological wise.
We are just at the end of our tether.

In my opinion the cutting edge geometry must be the problem- which cutting geometry can you recommend me?

Or you have any other ideas?
Thank you

Do you have sharp aluminum plates?? Then I would take plane cutting heads and warm up the lacquer slightly so then it is TOUGHER....

[Cncplaner]

Yes, the plates are sharp and new.
And we do use plane cutting heads, however the warming up doesn’t work.
It’s a series production: raw parts onto the device on the device ad go, the machines run for 24 hours.

Hss end miller?

[Cncplaner]

I don’t understand your answer?
Our measuring head is between 80 -160 mm (diameter) and have hard metal plates inside.

Hss is really really sharp. If you mill the contours with a hss miller, then it might work.
