?We have been having some issues Indexable drilling on our Lynx 2100. It is a 2 axis machine.

Running a DTI along the turret in the z direction it is 0.08mm (3 thou for those in the US!) out. So I am now trying to square up the turret.

My manuals do not show the procedure and other manuals that I have found online have a slightly different arrangement of bolts.

The turret is mounted on a sub plate and this is bolted to the carriage with 8 bolts, I have slackened all of these off.

On the left hand side of the sub plate there are two M8 tapped holes, one at the back and one at the front. I am guessing that these are to move the turret into alignment.

But when I turned the front one, the turret did move but it didn't seem to swing around a pivot; rather move parallel so that I still have the error.

I did notice that between the mounting bolts 1 and 2 there is a grub screw, do I have to wind this in to pivot around?

?Anyone have one like this?
