i planned on using a dial indicator and a deadblow hammer to try and eliminate runout on the tail end of the material, before engaging the tailstock. i never machined any parts this long before.
I was worried about chatter, I’m removing a lot of material, big end of shaft is 2.370, small end is 1.875, several diameters and a short threaded section. The part get turned between centers on a grinder for a 16 finish, customer told be to leave those diameters.019” larger for finish grinding.
So you think I only need to grab .150” in the chuck and support the other end with the tailstock? I was thinking I need to bore the jaws 1” deep. This material weighs 20lbs.
My cnc lathe has a 6” hydraulic chuck and hydraulic tailstock. I’m trying to machine a part, stock material size is 2.75” OD 14.50” long solid 1045 steel bar. My question is how deep should I bore the chuck jaws to hold this material?, I will be using the tailstock and live center.
My Milltronics ML1540 has a Pragati 8 station turret. I have never understood a cnc lathe without a turret. What’s the point?, your tied to the machine for every tool change.
