The engraving machine
What was once was done manually with a lot of work by a professional engraver in long hours of arduous work, today is done by an CNC engraving machine.
But not only in the professional field you can find more and more users, even hobbyists and beginners buy increasingly CNC engraving machines, in order to save time and effort and to obtain an accurate result.
CNC engraving machine is usable for:
- Sign engraving
- Engraving of pictures on e.g. stone, granite, marble or wood
- Labeling of any kind as Trophies, machines, technical equipment, grave stones
- Numbering of metal components (serial numbers)
- Personalized gifts e.g.Producing unique jewelry
- Making of 3D lithophanes
- 3D or 2D point marking
How does a CNC engraving machine work?
The abbreviation CNC stands here again for Computerized Numerical Control. A machine, in this case the engraving machine is, therefore, controlled numerically by a computer.
Previously entered data records are passed to the engraving system, so that they can be traversed appropriately and gradually until the desired result is achieved. This happens using a mounted on the engraving machine tool, this milles or scratches in thighest precision, complex and multidimensional forms, even in stone materials.
Engraving machines also exists in the form of laser engraving machines. Here the engraving is not performed by a mechanical milling body or graver, but levitated by a high-energy laser that burns/engraves precise into the workpiece.
In the selection of materials to be processed you are almost unlimited:
What should I consider when buying a CNC engraving machine?
When purchasing a CNC engraving it’s best to look for a technically competent manufacturer or seller. The most important rule when buying a Engraving machine or milling machines is:
The more accurate my machine is adapted to the needs of a workpiece, the more accurate the result obtained!
some preliminary questions should be answered:
What size should my engraving machine have? What are the maximum dimensions of the workpiece to be machined?
For a grave stone engraving I need a different size than for series identification plates.
Principle of “Bigger is better” – If I buy a smaller engraving machine I am limited in terms of future projects, if I buy a bigger one, I have more flexibility in the implementation of major projects.
What should I consider when buying the tool? The accessories are an important criterion. Here it is essential to use the right tool, suitable to the material of my work piece and the performance of my machine. Rotating tools (Engraving) are used but also fixed Slicing machines (mostly diamond tips) for various purposes. Again, advice should come by a well-trained salesperson.
Do I necessarily need a suction when engraving? As it comes to increased dust production, by removed material when engraving, you should draw a suction into consideration. The dust can change the engraving depth and hence also the precision of the result. It may also (especially with abrasive materials) come to buildup on the mechanical components of the engraving machine, which may affect the function of the CNC engraving machine.
- Expert advice
Do I get competent advice? As with all major purchases, the quality of advice should be an important aspect of buying.
A good, professionally trained retailer or manufacturers of high-quality CNC Engraving machines, is always on hand to advise, even after purchase. Thus, buying an on your project perfectly tailored machine makes the entry easier and the results will be more precise.
