Abrasive Troubleshooting

Troubleshooting Reference Chart

Many belt sanding problems can be alleviated by observing the proper belt speeds, tensions, and feed rates as listed below.

Measurements:

Belt Speed: Surface feet per minute (SFPM)

Belt Tension: Pound per square inch (PSI)

Feed Rate: Feet per minute (FPM)

Horse Power: Per inches of belt width

Application	Belt Speed	Belt Tension	Feed Rate	Horse Power
Rough lumber sanding and planing	6000+	70-80	30-125	3 to 5
Abrasive finish planing	3800-7500 5000(common)	65-75	45-50	1 to 3
Intermediate wide belt sanding	3000-6000	75-90 (poly/coarse grits) 55-70 (cloth) 45-55 (paper)	20-70	1 to 2
Man-made board sanding	6000-7000	75-90 (poly/coarse grits) 55-70 (cloth) 45-55 (paper)	80-200	100 to 250
Cross belt polishers	4000-8000	N/A	20-60	15 to 30
