The sound of the chips pinging like hail on the vertical lathe never gets old (for me watching the occasional video :0) it might be different for you!)
Smax 32767, lol! Btw, how is the spindle drive implemented on such vertical lathes? Gears, big belt or even direct BLDC drive? Motor, is it on the side?
My job is refurbishing those chocks. Milling and drilling new rocker and wearplate surfaces, thread and hole repairs after oversizing or spraywelding the bore. Currently machining a 15.500kg topside, 1275mm bore...Those are the biggest we can mill and turn, though milling alone we can do bigger. Too bad I can't upload those big boys up here. Whats the biggest chock you can machine?
It's fun working on the big stuff isn't it most of our peices we machine at the place I work are roughly over 6-8 tonnes some of the bigger stuff reaching 14 we make dies for hammer forges have two of the largest CNC miller's in the UK well at the time we brought them
Generally your first work offset is based on an average. So as an example, you'd get the average center of that hole, and the average of a face, and use that as g54. The hope is, after your first operation, you have at least 1 datum that you can use for positioning the rest of your offsets for other operations.
@@grinchyface In my shop when we do rough forgings/castings, we use the milled datum face as the Z0/G54 on the turning ops so all dimensions come from a known flat dimension. It has its benefits, but make programming a little more of a pain
I think i recognize these parts, they come in pairs in the middle it Will hav a Huge cilinder inside. A cilinder on top of another, the purpose, to reduce the thickness of large sheets of metal if im not mistaken.
Using the numbers you show at 0:39 and an estimated hole diameter of 800mm this casting weighs in at around 4560kg or just a tad over one short ton of 2000 pounds. That is a far cry from 8000 pounds or 4 tons as indicated in the videos title..........
