Engraving, Finishing and Polishing Perspex

Engraving Perspex

Perspex® is easy to engrave using pantographs, CNC engraving machines or laser engravers for very fine detail. Mechanical engraving can actually be performed dry but all swarf must be cleared and the cutter head kept cool. Compressed air directed onto the cutter and work piece would be preferred.

Polishing

Power buffing with rotating calico mops may be used on the sanded surface with a mild, abrasive buffing soap. Moderate speeds and only light pressure should be applied to prevent overheating.

Diamond polishing can be used for straight edges without the rounded edges produced by buffing and with very little stress.

Flame polishing can be used for thin edges of Perspex® and is fast and effective. Care must be taken not to ignite the surface of the Perspex® and it should be noted that flame polishing can produce highly stressed edges. After flame polishing it will be necessary to anneal the work if bonding or surface decoration is applied.
