I need to machine some concave cuts into a set of pinch rollers.
The rollers are used to roll copper tubing into fairly tight coils. I need to cut 8mm, 10mm and 15mm concave grooves into the steel rollers.
Rather than use form tools ( even tho' the misses is a bit deaf the chatter would be unacceptable) I fancy the Repton ( from Cronos
http://www.chronos.ltd.uk/engineering-tools/2013/2562/. They state a maximum capacity (both Concave and Balls) but no minimum.
As there is a tenner off the price I am sorely tempted.
Does any one here have one? Can it cut a 8mm concave half circle out of steel?
Can it make me a new set of balls out of 316 SS? (XXXL Please)
