howard-grivnaThere are several factors that affect a wide belt sander’s ability to hold a close thickness tolerance. When a sander is new, with proper operating procedures, any rigid orifice-type machine should reasonably hold plus or minus .005” tolerance. If a machine has been specifically designed and has the right characteristics to hold a close tolerance, thickness tolerances of plus or minus .0025” are achievable. However, within a short period of time (less than one year), certain wear factors require machine maintenance procedures along with proper operating procedures in order to continue to obtain tight thickness tolerances.
