Machining HDPE
Machining HDPE
(OP)
We asked a machine shop to make some parts for a pump intake out of HDPE pipe and 1/2" thick sheet.
The machinist if having severe problems, breaking bits, bending tool shafts, etc.
I know nothing have seen nothing, but that seems strange, very strange.
The machinist has never machined anything as soft as HDPE, has no idea what he is doing, but I know he has machined some harder plastics for us no problem.
I know this is vague, but I know nothing at all about the subject.
Any big hints would be appreciated.

Woodwork tools work best. High speed steel tools will work.
If you sharpen your own tools, compared to woodworking specs, use very low rake angles to avoid digging in, use high back clearance angles to reduce friction, use extra set or side clearance to reduce friction and allow for clearance of schwarf.
