Lost grub screw! - HAAS VF-4
Hi,
First post, here goes;
I've got a 1998 Haas VF-4 and I've been having spindle orientation problems. I've took the covers of the headstock and it looks like the encoder pulley on the shaft end is missing a grub screw. I've got the pulley on the encoder, a toothed belt, which looks fine and then another small pulley that I can stop with my hands when I rotate the spindle. Obviously this is causing the encoder to be 'out'.
I've noticed there isn't actually a flat where the missing grub screw sits which is strange, is that normal?
Anyway, my main question is - does anyone know what size thread this grub screw will be? It looks *roughly* 3/16, not sure on the pitch/tpi.
Thanks.

An open mind is a virtue...so long as all the common sense has not leaked out.

You Will Need To Set Parameter 254 After You Have It Tightened Down ..
Disregard that last one .. oops ..257 ... not 254
Yeah, 8-32 was the one, thanks!
Don't know if it's worth starting a separate thread for this, I've got a damaged waycover on this machine.
Where would I go about getting a replacement, is it a direct from Haas job?
I'm in the UK, has anybody got any ideas of prices?
I guess it would depend on how fast you need to be back up and running. If things arnt tight I would checdk around locally. Your best bet to get back up and running fast would be to call Haas direct or Arthur Machinery 1-800-562-2423 out of Chicago Illinois.

Try these guys, way covers repaired fast turnaround.
I have one of their replacement way covers on the z axis of my fadal. It's great quality and about half the price of the teleflex cover.
