During the rotary engraving process, a milling cutter moves over the surface of a clamped workpiece. The rotary motion of the milling cutter removes one or more layers of the object. For example, letters or patterns can be "milled out" of a material. Metal surfaces are particularly well suited for rotary engraving. For example, deeply-engraved letters and motifs can be enhanced with color to increase the design's contrast.
Advantages of Rotary Engraving.
- Achieving a relief effect: Deep engraving is possible with metal objects.
- Beyond metal engraving: Metals be drilled and cut with a rotary machine.
Disadvantages of Rotary Engraving.
- Limited level of detail: Small details, in particular, are difficult to achieve.
- Wear and tear: The milling head wears down and requires regular replacement.
- Clamping required: Each object must be clamped, which increases production time when processing a series of workpieces.
- Not suitable for many materials: Creating fine engravings or cuts on paper or leather is not possible. Rotary engraving may also form jagged edges on acrylic objects.
- Material compatibility: Wood, glass, textiles, paper, metal, and plastics are only a few materials that can be processed with a laser.
- Non-contact cutting and engraving: Workpieces do not need to be clamped.
- Minimal tool wear: Unlike a rotary machine components, laser equipment can last for ten or more years.
- Very high precision: A
- Economical for individual pieces and series: One or multiple workpieces can be quickly processed.
