Buffing Wheel Pressure for Polishing and Buffing

Rotate speed and buffing wheel pressure are two elements that must work together to produce the best finish in a safe, economical way. Proper pressure must be applied to the workpiece to produce the friction that allows the compound to buff. In tangential buffing, enough pressure should be applied to the workpiece to cause the buffing wheel to flare slightly at the point of contact. Inadequate pressure gives no buffing action, but excess pressure may cause the speed of the buffing wheel to be reduced and /or cause the buff to collapse and the operation to be less efficient or even dangerous.

One of three chief causes of buffing wheel fires is excessive pressure. The cause of a fire can be determined by where the fire starts on the buffing wheel. If it starts at the ring it usually means that the buff is spinning on the shaft and the head was not tightened properly. If the fire starts in the middle of the buff, it usually means that too much pressure is being applied. If the fire starts at the periphery of the buff it usually means that the buff is turning too fast or not enough compound is being applied.

enerally, medium / hard pressure for first stage polishing, and light pressure for finial high polishing.
