A agricultural customer has asked me to sort his stone crusher, the drive pulley and flywheel have gone slack on the shaft and damaged the key ways in them. They are 1m in dia and 120mm bore, 32mm key. They are to big to go in my lathe so I was thinking to weld up the bores and machine them out with the boring head on the milling machine, I’ve not broached a key way that size before though. The other option my old boss mentioned to me was to bore them out and fit taperlocks with parallel sleeves. Has anyone used those before or got any advice on a job like this?
Cheers
