Engraving Materials for Rotary Engraving Machines
One of the great advantages of having and using a rotary engraving machine is the wide variety of materials you can engrave. Although most engraving professionals are familiar with using these materials, they may not have tried them all with a rotary engraving system. Here is a look at five categories of materials - wood, plastics, glass/ceramics, metals, and SignFoam - that can be engraved with a rotary engraving machine.
Wood
Almost all types of woods can be engraved with a rotary engraving machine, from hardwoods such as oak and walnut to softer woods such as pine. Simple designs and text can be cut into the wood; with the addition of a routing head, complex designs and simulated 3D graphics can be cut out.
Plastics
All types of plastic can be engraved and cut on a rotary engraving machine, including engraver's plastic, acrylics, and PVC. With engraver's plastic, users can create a wide variety of signs, name badges, control panels, gift and promotional items, and much more.
In acrylic, many types of awards, plaques, and signage can be created. Reverse-engraving in acrylics using a rotary engraving machine gives a special beveled look that cannot be accomplished with a laser. The cutters used with a rotary engraver provide additional angles for the reflection of light, giving a multi-dimensional look.
Glass and Ceramics
Glass, crystal, and ceramics can all be engraved with a rotary engraving machine. Applying water to the surface of the material keeps the engraving area cool and reduces the chance of fracture and flaking.
Metals
Aluminum, brass, steel, copper, bronze, and precious metals such as silver, gold, platinum, and titanium can all be engraved with a rotary system. A non-rotating diamond can be used for diamond-drag or scratch engraving on a variety of metals. A rotating diamond or burnisher is often used on painted metals such as coated brass for plaques and awards. When deep engraving metals such as stainless steel, it is necessary to use some type of coolant on the surface, such as cutting oil. This will increase the tool life of the cutter and enhance the quality of the finished product.
SignFoam
SignFoam is a lightweight, high density polyurethane board that possesses strength and durability, making it a popular material for creating both interior and exterior signage. It is easily engraved with a rotary engraving machine or router, and is perfect for creating 2.5 and 3D signs. Like wood, cutouts can be painted to create multi-colored signs.
Conclusion
A rotary engraving machine - combined with the latest engraving software and a variety of materials - can offer thousands of possibilities for an engraving business. Your options are limited only by your creativity!
