CNC engraving

CNC engraving

CNC engraving (see also: CNC milling) is a computer operated process with a spinning mill that removes material from the top of (wooden) panels to make a decorative drawing or pattern.

After engraving, the wood needs an additional sealant (oil, paint, or varnish) to protect it from moist or dirt.

The life cycle	Pro	Con
	Low footprint No additional materials are used. However because it is not protective, an additional finishing layer could be needed.	High energy Even though no additional material is added for CNC engraving, drillbits (the tip of the tool) need to be changed often.

		High investment CNC milling machines are expensive, especially the size that you need for engraving large surfaces.	Tips Dusts from CNC engraving are safer if the material is untreated wood, but can be a hazard to health if the material is MDF, particle board (especially with synthetic lamination) or painted or lacquered wood. If you work with these materials, you have to make sure that there is a proper aspiration system in place.

	Non toxic Engraving does not have toxicity issues, if you avoid protecting with unsafe finishes. Long lifespan The treatment is durable, as it takes off part of the material permanently.
