Countersink Milling with new Tool

[JiXXeR750]

Good Evening Everyone,

Just a quick question.

We just purchased a new 20mm Chamfer Tool to be able to machine a few larger holes in various jobs.

My question is how do you all precede this process ?

I have been drilling a through hole, then trying to get the tool to peck drill down to closer to the final surface, then use the Bore operation to do a final pass.

The finish is pretty decent, but just wondering workflow wise, what everyone might be doing differently ...

Any help of guidance would be greatly appreciated.

We use a Ø20mm tipped chamfer tool to chamfer all of our threaded ports.

The process we use may work just as well for countersinking holes, depending on the diameter/size of the countersink.

Drill the through hole, then we use 2d contour

Select the lower chain in geometry

Then select chamfer in the passes tab and adjust the tip offset as required.

You may have to adjust the leads and transitions and/or the number of passes depending on the size of the countersink.

I'm sure there are other options available.

Hope that helps.

I just did this for some .56" chamfers in copper with our nine9 tool. Plunged to .53 (very chattery) then finish cut to size. .001" feed per tooth, on the low end. Dont forget to compensate your SFM to the actual effective diameter.
