PLEXIGLAS^® SHEET: MACHINE BUFFING

	The Plexiglas® sheet should be clean and dry at the start of each buffing operation. Some polishing compounds leave the surface clean after buffing. If these materials are not used, washing should follow the last step in polishing.
	If the part has previously been sanded or is deeply scratched, an abrasive coated wheel is used first. The abrasive is a standard polishing compound composed of very fine alumina or similar abrasive and tallow.
	When most of the scratches have been reduced on the first wheel, the Plexiglas® sheet is buffed on the second wheel, charged only with tallow.
	The first two wheels should be air-ventilated cotton muslin rag wheels operating at 3,000 to 4,500 surface feet per minute (SFPM). SFPM = 1/4 diameter of buffing wheel in inches x spindle speed in RPM.
	The Plexiglas® sheet is next brought to a high polish by a soft loose buff in which no abrasive or tallow are used. These buffs should be made of imitation chamois or cotton flannel. The diameter of the wheel should be 10 to 12 inches and run at 3,000 to 4,500 SFPM.
	A hand-applied coat of wax may be used in place of buffing on the finish wheel, if desired.

Caution: Avoid the generation of excess heat during the buffing operation. Excessive heat leads to stress in the acrylic which could degrade its physical properties.
