Laser Calibration for Deep Hole Drilling Machines
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. ...
