Consistent care and maintenance is necessary to ensure your tool's peak performance for many years to come
There 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.
In previous issues, we have addressed the following questions:
Table A allows you to compare abrasive belt mineral sizes based on several different grading systems. Please note that the P-designated belts (European grades) are a different mineral size than the X-designated belts (U.S. grades] except for 180 grit.
