Machining nylon - please help

gakor from Behind You -

Hello,

I wonder if you guys could be kind enough to share your experience machining nylon. I have 20, 000 bushings to cut. The bushing is 9mm long +/- 0.1, 10mm OD, and 6.6 +/- 0.1mm ID. I have never cut nylon before. I would appreciate a heads up so I have some time to prepare. What inserts would you guys reccomend? What brand? What feed, and what speed?

Customer supplies solid rods, so I have to drill. What drill would be suitable to do the job quickly and leave a nice finish?

I think they mentioned the nylon type to be LC94, PAS. This is not for sure, though.

Thanks ahead.

Try to rig an air line to blow chips away from work/keep work cool rather than using coolant.It will run fast so keeping chips out of the way is half the battle. Sharp inserted tools like kennametal dpgt-hp or similiar(upsharp or high positive)for turning.Half round or strait flute drills from Ohio Drill work well for drilling. Good luck.
