Choosing the Right Way Oil for Deep Hole Drilling Machines
Way oil lubricates the machine guide ways and prevents stick-slip motion during slow feed movements. Deep hole drilling machines operate at low feed rates — 0.01-0.10 mm/rev — which makes stick-slip a potential problem. I have dealt with stick-slip on three different machine models and the fix always came back to the right oil selection. Viscosity Selection by Way Type The oil viscosity depends on the way type. Box ways need higher viscosity oil than linear guides. For box ways, I use ISO 150-220 way oil. For linear guides, I use ISO 68-100 way oil. ...
