Hi folks, it's been a while since I last posted, having not been doing much of interest in the workshop until now.
Yesterday, my annual bonus went toward a Sieg SX2LF Milling machine. I spent yesterday cleaning off all the packing grease, relubing everything & bolting to the workbench followed by some test cuts.
These test cuts showed the cutter wasn't cutting evenly (evidence of a tilt), so I put a dial indicator in the quill mounted on it's arm, and checked both ends of the table.
I found a 0.40mm difference from left to right and about a 0.1 mm difference front to rear. This was with all of the axes clamped. This difference is pretty consistent regardless of column height or table position.
I checked the alignment of the spindle with a piece of hex bar in a drill chuck and it seems OK. I checked the difference in level from front to rear and that seems OK too. I tried loosening the holding down bolts in case the benchtop was warping the base, no joy there either.
It would be simple to fix it, except that this model Sieg does not have the tilting column.
The column is held down by four mounting bolts. I've done a search procedures but they all refer to the X2 type with the tilting column.
Should I remove the column and try shimming one side? or is there an adjustment I might have missed. The user manual is no help at all. I suspect Google translate was one of the authors.
