Different Tooling For Different Groove

Here is a new aluminum part from milling.

For the old design,  there is a little space between the groove to the thick  edge.

So we can use the short  tooling with a bigger milling depth.

But for new design, the  groove it is close to the thick edge, and we must use the longer  tooling.

It makes the tooling  easily broken as the strengh is much less. 

Also we can only use  the 2.5mm milling tooling to do the 2.5mm groove.

That means we need to  make the tooling vertical during the production.

Any slight move will  hurt the milling tooling and also the part. So the milling will be very  slow.

For your reference, the  rough milling we can do 3-4mm thick, the presiced milling depth can be  0.8mm.

But for this groove we  can only do at most 0.1mm thick.

Welcome to send us your drawing, we are happy to offer the idea from production.
