Does anyone use the stop screw in the back off shrinks anyway? We remove the screw and drill the back out clearance so the cutters can go in for miles.
Obviously will not work on larger holders but up to 12mm works fine
Doesn't affect the performance of the shrink in any way
Also makes removing broken cutters easier
If you have a decent induction shrink, put the holder in the freezer, then with a rod up the pull stud hole loading the steel cutter give it heaps with induction. If it gets hot without coming out, put it back in the freezer and try again. We have good success this way and do it regularly. I have only had one tip cutter that I haven't been able to get out.
A cheap shrink system is false economy but some bosses don't see it that way. Shrinks have been the greatest advancement we made and has more than paid for itself over the last 20 years (still using some of the original shrinks)
Hope this helps
Worth a try
We have been using it for the electrodes on our sparkers for 20 years plus. Great for milling, grinding, turning electrodes they repeat well. You can even buy copper blanks on shafts ready to go. Once you build up a stock of base plates and shafts makes manufacture of electrodes simple and fast
Good quality shrink holders are the only way to go. We use them all the time very seldom use collet chucks (got lots of them collecting dust)
Shrinks are a bit of an initial investment, but last for ever when looked after and extend cutter life
Did I hear right ????? America and metric in the same sentence
Just found out Noga clocking attachments don't like 5000rpm. It flew apart (surprise), but I put it back together and is still fine. More than I can say for the clock. I've had the Noga base and clocking attachment for years and use them all day every day (first time one has been abused). Only way to go (genuine Noga's) but not at 5K revs (still mad at myself)
