Warco Major CNC build log

[Robin Hewitt]

I cut some metal and it came out a bit naff, see before and after pic, arrow points to the problem bit.

Two changes, I wrote my own dxf to G-code software taking control of the tool path. Bubba, over on CNC zone, told me the Warco column pinch bolts were naff.

I've been measuring the new part and dimensionally it is slightly undersize, somewhere between -0.00 and -0.05mm

Theoretically with a bit of compensation I could get the tolerance down to .025 mm if I always used this tool and this collet :dance:

Bubba suggested I changed the bolts. I looked at them and found they had worn badly. When I thought I was doing them up tight I was actually trying to swage a new thread. I fitted overlength M16's with spacers and anti-seize compound. I can now use a ring spanner rather than the awkward Warco offering and it seems to like it.
