Machine-Alignment

I have seen shops spend weeks chasing straightness problems when the root cause was a spindle that was 0.03mm out of alignment with the bushing. Checking alignment takes thirty minutes with a test bar and a dial indicator. Here is the procedure I use. What I Check and In What Order I check alignment in a specific sequence because each step depends on the one before it: Spindle condition (runout at the taper) Spindle axis parallel to the way axis Bushing holder concentricity with spindle Bushing ID concentricity with spindle Workpiece axis alignment with spindle If I skip a step, I waste time chasing a problem that does not exist. ...

Laser calibration measures the actual machine geometry against the ideal. It catches errors that mechanical methods — dial indicators, test bars, and squares — miss entirely. I’ve used laser calibration on deep hole drilling machines after major moves, spindle repairs, and when chasing accuracy problems. The results have saved me weeks of guesswork. What Laser Calibration Measures A laser calibration system measures three critical aspects of machine geometry: Linear positioning accuracy. The laser measures the actual position of each axis against the commanded position. This catches pitch error in ball screws, encoder errors, and thermal drift. A laser interferometer is accurate to within 0.001mm over a 1-meter travel. ...
