Especially when harder metals are being engraved, there’s nothing that packs a punch quite like it.
#ROLAND EGX 350 REVIEWS SOFTWARE#
For a simpler solution, standalone systems with their own built in computers and software are also very popular.ĭot peens are known for their simplicity and high speed markings. “Peens” are also apt to being integrated with other components as part of a larger system or an assembly line.

However, in this industry, the term dot peen is used to portray the more robust versions of the technology that are offered in either pneumatic or electromagnetic configurations. Impact printers are really just smaller, less powerful dot peens. The result is a series of dots that when strung together creates text, photos, logos and 2D data matrix codes. Both utilize a diamond stylus to strike downwards onto the material in order to create a deep indentation. On top of that, you will need to consider the ongoing cost of cutters, lengthy setup times and finishing touches all of which affect your return on investment.ĭot Peens are most often used solely for part marking, while an impact printer can come in handy for things like personalization and photo engraving. Cylindrical capabilities usually come at a steep price and the sizes of the items you can accommodate are rather limiting. Rotary engravers are also more reasonable for engraving flat items. On the contrary, as there is a physical tool making contact with your material, everything needs to be clamped in place to keep it from moving. Best of all, you can set one up almost anywhere and they are safe enough to leave running unattended. Standard power and perhaps a chip collection system is all you will need. Plus, they are relatively easy to operate and there aren’t many additional components or requirements to setting one up. The nice thing about rotary engravers is that up to a certain hardness they work on just about every solid material type you can think of. Like with most equipment, the beefier it gets, the slower and less precise it moves. The tradeoff between the two comes in the form of speed and resolution. The larger units are often called CNC routers, which really just means the spindle motors are stronger and the machine bodies are more rigid so that it can handle the cutting or routing of thick substrates.
#ROLAND EGX 350 REVIEWS PORTABLE#
Rotary engravers are very popular and range in size from portable desktop units to large flat beds that can accommodate a 4 foot by 8 foot sheet of material. Rotary engraving machines use sharpened tooling such as carbide cutters, end mills or diamond gravers to either engrave, cut, or scratch various materials in a routing-like fashion.
