Machining castings is always fun , there is usually a ton of stock to remove to get to final size , Sometimes it's a balancing act to make sure there is plenty of material to remove on all machined surfaces . We used to have a VTL were I used to work but it never ran much and they sold it before I got to operate the bigger machines . I used to run alot of casting and weldments on my machine a 6 inch G&L Cnc horizontal boring mill . 3oo tons is nice but the hydraulic extrusion presses we built were 1800 to 4500 ton aluminum and brass presses .
I would use old firehose from a local fire department or old cut straps to protect your rigging from sharp edges. Seen a guy drop a 25k lb rock crusher casting cause of it.
How did you dial the second side of the piece work? You have to have some machined OD diameter from the first side to get some reference for machining an opposite side. I didn’t see that in your video!!!???
Another good video! Less than 24 hours since posting and already over 7,200 views! You forgot to mention that you changed from the larger Richards VBM to a smaller more modern machine. Is the Richards a retrofit machine?
@@jamespark_85machiningtv Almost looks like the crossfeed screws are still an Acme thread and not a ball screw. Good machine for roughing, but probably doesn't have the RPM's for finishing or smaller diameters.
It always boggles my mind how they used to do stuff like this this 200 years ago without Tungsten Carbide tools and a C.N.C. Sand castings wear the Toolsteel Tools out so fast. And yes I know it was done by hand on a BIG Boring machine, but, how did they make the Big Boring machine in the first place......mind boggled.
Don't take this the wrong way, but your machine has more chips laying around than a Lays factory.. Clean your workplace, a happy machine is a clean machine.
