Pexto Ring and Circle Cutter
Pexto Ring and Circle Cutter
I just scraped enough money to buy a PEXTO ring and circle cutter model 298-3 serial number 43 on eBay. The slipping rolls are worn and leave a burr on the cuts. I called Roper Whitey and they no longer make replacement slitting roll for this circle cutter and the rolls for the RW 299, their current ring and circle cutter will not work. Any suggestions on where I could get replacement rolls? Also is the lower roll left hand thread. RW said try a job shopper to machine new rolls but this seems very expensive. Any suggestions on this?
Re: Pexto Ring and Circle Cutter
When dealing with a bureaucracy asking the same question twice often results in different answers and in this case that was true. My second call to Roper Whitney revealed there was a high probability that the slitting roll from a newer ring and circle cutter (299) would fit an older vintage ring and circle cutter (298); providing the threads to attach the slitters to the shafts were the same, which they were (on very early models they were different). Problem solved!

Interesting. Sometimes the answer may be diferent with another person within the company.
Sometimes cutters and shear parts can be given new life by adding shims or polishing worn edges to reduce the wear marks, usually a rounding of the cutting surface, that causes the shearing action.
Good luck.

Re: Pexto Ring and Circle Cutter
I have the 299 circle cutter, a couple of things that can cause the problem you mentioned, one is dull cutters, if you have a lathe and toolpost grinder or have a friend with one a clean up pass will do wonders for the cutters. Second is the cutter adjustment, they will adjust a little to shear different gauges of metal. The setting (gap) ???? you might see if some one at Roper-Whitney can give you that info, (3 thousands come to mind but not a 100% sure) also check for run out (slop) in the cutter shafts. Good luck with your machine! tt
