I'm using a Maier to make parts from Ti6Al4V Grade 5 Titanium, but the swarf is causing me problems. One operation is a long 1:50 taper and the swarf wraps around the job, meaning I have to pause the job and manually remove the swarf before head 2 can take the job for the stock end operations.

The finish I'm getting is really excellent, the tool inserts are those recommended for the job and they last well.

I have tried various speeds and feeds, as well as positioning the coolant jets from all angles - no difference. I'm using normal suds, water based mix.

A long google hunt produced a paper about using high pressure coolant accurately aimed into the cut, to force the swarf into a tighter curl and promote breakage.

My machine doesn't have high pressure coolant, but I'm thinking about trying to rig up something. Have any of you guys tried this ? OR, is there another method of removing the swarf I have missed ?

Thanks,

Zorbit.
