In the mechanical engraving process, a milling cutter moves over the surface of the clamped workpiece. The rotary motion of the milling cutter removes the surface of the material. For example, letters or patterns are milled out of a material. Plastic layered materials can also be engraved in this way. Metal surfaces offer a particular advantage in mechanical engraving: The deep machined lettering or decorations can be designed with color to increase the contrast.
Advantages of mechanical engraving.
- Deep engraving possible with metals.
- Metals can also be drilled and cut.
Disadvantages of mechanical engraving.
The following limits apply to mechanical engraving:
- Limited level of detail: Small details, in particular, are difficult to process.
- Wear and tear: The milling head wears down and needs to be changed regularly.
- Clamping required: For mechanical engraving, the workpiece must be clamped. The time required for this is a hindrance in the production of series.
- Not suitable for many materials: Fine engraving or marking of paper or leather are not possible. Mechanical engraving is not suitable for roughening the surface of acrylic.
Laser engraving offers these advantages:
- Suitable for lots of materials (wood, glass, textiles, paper, metal, plastics, etc.)
- Material doesn't need to be clamped. Non-contact processing.
- No tool wear
- Very high precision
- Economical for individual pieces and series
