Support Material UpdateUpdated technical literature and support materialsUNIVERSAL5Swirl-Free Check List:Equipment Check:Sander:Random orbital sanders are designed as finishing sanders. To achieve the best finish results, use thesander as a “finishing sander”. Do not exert heavy downward force on the sander. Apply enough downwardforce to keep the back-up pad and abrasive flat on the surface while still allowing the back-up pad to orbitfreely over the surface. Remember – let the sander do the work.Match the sander to the work. For heavy and faster cut rate use a sander with a 3/8" diameter orbit. Formoderate cut rate use a 3/16" diameter orbit, and for the lightest cut rate, and the finest in finish sanding usea 3/32" diameter orbit. Excellent results can be accomplished by selecting the correct sanding action, thecorrect grain abrasive, and the correct sequence of abrasive on the selected sander.Example: Heavy/Fast Cut Rate: 3/8" orbit - < 150X.Moderate Cut Rate, Fine Finish: 3/16" orbit - 150X – 220XLighter Cut Rate, Finest Finish: 3/32" orbit - 220X >3/8" (10 mm) Dia. OrbitFor Aggressive Sanding3/16" (5 mm) Dia. OrbitFor General Sanding3/32" (2.5 mm) Dia. OrbitFor Ultra-Fine SandingCheck the orbit diameter that is being use for the application. In some cases a 3/32" orbit is morepreferable than a 3/16" orbit.90 PSIG (6.2 Bars) is the required operating air supply pressure. Check the air pressure at the sanderwhile it is running. Note: Promote the use of Dynabrade® maximum flow plugs and couplers to ensureproper airflow.Confirm that the tool is running at the rated "Free Speed" RPM. On an average a 10,000 RPMnon-vacuum sander will run at 9,500 RPM; a 12,000 RPM non-vacuum sander will run at 11,500 RPM. Avacuum sander normally runs slightly slower.Note: Removing the sanding residue from the work surface with a central or self-generated vacuum sanderwill improve the finish. It will also help to extend the life of the abrasive. Consider using avacuum style sander.Inspect the balancer bearing (pad bearing). Remove the back-up pad and rotate the balancer bearingshaft while holding the counterbalance stationary. The balancer shaft should turn freely.Back-up Pad:Abrasive:Inspect the face of the sanding pad. The pad must be flat and smooth, without any defects. Check if theyare using a Dynabrade back-up pad that is “weight-mated” to the sander. Using another pad can make thesander vibrate excessively and lead to an unacceptable finish.Dynabrade orbital pad face run-out is ONLY .002 - .005. Competitors can be up to .015 - .040.Use a good quality abrasive. Abrasive product that has an additive to help prevent loading of the sandingdisc will provide a superior finish than abrasive that has no additive. When sanding particularly sensitivesurfaces such as Corian® and other acrylic solid surface it is best to use a film backed abrasive sanding disc.Film backing forces the abrasive to lie flat on the surface. The grain is then presented to the sanding surfacein a very uniform manner.
Support Material UpdateUpdated technical literature and support materialsUNIVERSAL6Swirl-Free Check List (Continued):Sanding Techniques:Always START the sander ON the surface, and STOP the sander OFF the surface.When sanding keep the sander, and pad FLAT on the surface.Important: Do not exert heavy downward forceon the sander. Apply enough downward force to keep the back-up pad and abrasive flat on the surfaceallowing the back-up pad to orbit freely over the surface. (see Fig.1)For peak performance, avoid tipping the tool/padwhen operating. Best results will be achievedwhen keeping the pad as flat on the work surfaceas possibleFig. 1WRONGRIGHTFollow a set pattern when sanding. It is suggested to pass over the surface following a “North, South, East,West” pattern (see Fig.2), overlapping each pass ¼ the diameter of the back-up pad and abrasive. Thisinsures that the previous scratches are removed and that a uniform finish is achieved. Two “patterns” persanding step are recommended.Fig. 2SandingPatternEndStartFrequently inspect abrasive for tears, folds, or build-up. When changing abrasive to proceed to the nextsanding step, first inspect the condition of the abrasive that is on the sander. If any defects are noticed in thatabrasive, remove it and install another piece of the same grain and sand the work surface again beforeproceeding on to the next sanding step.Always clear away sanding dust and abrasive debris before progressing to the next sanding step witha finer "grit" abrasive.PDF Version Available (TYPE URL INTO BROWSER)http://www.dynabrade.com/pdf/lit/SwirlFreeCheckList.pdf
