My dilema......uuuuhgggg!!!

admin

I need something that will bore  5/8 hole thru a uhmw pc of round stock 2.5 inch in diameter.5 inch long..we make rollers for ramps and doing it in an end mill is a pia....mini lathe????
Reply:Can you bore a long length and then cut it into .5 inch long pieces?Lincoln SA200's... at least 15 - 20. They come and go. Growing partial to the "Short Hoods" in my old age. Last count on Short Hoods was 13 in possession.
Reply:I would think you could have probably ordered it with the hole already in it..other than that, probably be a lathe and drill bit, actually a the uhmw clamped in a decent v-block with a decent clamp and a piece of aluminum or wood under it so you dont drill into the table probably wouldnt be to bad..  use coolant, on that uhmw some liguid dishwashing soap mixed thick with water will probably work fine for coolant enough to get you by,  if you dont have coolant..tackleexperts.comwww.necessityjigs.comhttps://www.facebook.com/groups/mach...dingequipment/
Reply:How are you holding the parts right now?A small three jaw chuck bolted to the mill table would work. If your doing a lot of them then bore some soft jaws that support the disks well.You can also get some aluminum stock and make some soft jaws for your mill vice. Bore your 2.5" diameter into the jaws so the part is held between the halves.A lathe would be my first choice... but try to use what you have first.
Reply:I still have a Yeasu indexer that we used to mount on the mill table and run C-5 collets  for doing multiple parts like thatYou can get C-5 collets that can be bored for holding custom parts and the lathes we had were camlock so you could take off the chuck and they had the collet draw bars on themThose collet set ups make jobs accurate quick and repeatable The Yeasu indexer could also be fitted with a threaded back chuckBacked my CATMA over your CARMA oops clusmy me  What would SATAN do ??

Reply:Mini lathe should work - just put the external jaw set in the chuck (left half of this pic):You'll need a drill or end mill with a 1/2" shank if you've got a 1/2" chuck in the tailstock.  I've heard UHMW machines well with those cold air guns like Exair and others make.
