The replacement frequency for sandpaper and consumables on the NG-AutoPol system depends on the specimen material, polishing parameters, and production volume. Under normal laboratory conditions, sandpaper rolls typically last for 50–100 specimens per grit, depending on hardness and surface condition of the materials being prepared.

The integrated cleaning system extends sandpaper life by removing debris during each polishing cycle, but replacement is still recommended once surface performance begins to decline or the polishing time increases noticeably. Other consumables, such as cleaning pads and fixture inserts, should be inspected weekly and replaced as needed to maintain uniform pressure and finish quality.

NextGen advises keeping spare sandpaper rolls in multiple grit grades, commonly 200, 400, 600, and 800. Regular monitoring and timely replacement of consumables guarantee consistent surface results, prevent over-polishing, and sustain compliance with tensile and fatigue testing standards.
