The Four Basic Techniques Available
For Today’s Engravers
Engraving takes a piece of precious
metal, stone, or wood and gives it a unique look while endowing it with
a sense of permanence and ownership.
The engraving process etches designs, signs, or insignias into the
surface of the material by removing a portion of it.
The four basic techniques that are available for today’s engravers
include hand engraving, pantograph, computer numeric controlled
engraving, and laser engraving.
The most ancient, and expensive, method of engraving is hand engraving.
Using hammers of various weights, chisels, and other sharp tools with
various profiles, designs are meticulously tapped into the surface of
the material. Accuracy and precision are required with each and every
stroke in order to achieve the proper overall look to the design.
A magnifying glass, or other enlarging equipment, is often required for
the hand engraver to fill in the minutest of the design details.
Another manual engraving method is the pantograph
or drag method. In this old method a device (the pantograph, otherwise
known as the tracing machine) scrapes the surface of the material with a
sharp stylus.
The pantograph is used to trace the designs or letters from the design
drawing to the surface of the material. This method is often imprecise
in creating the designs and letters, giving the final product an uneven
look.
One benefit of this method is that it is faster than hand engraving. You
are also unlikely to get mistakes resulting from shaky hands as the
stylus operator controls the writing.
A computer controlled method of engraving that gives you a more precise
outcome is computer numeric control (CNC) engraving. A graphic software
package that is similar to cross stitching is used to give you letters
and designs that are uniform in appearance.
The computer is able to take the images and translate them into numeric
instructions for each movement of the machine. You can change to fonts,
sizes, and designs that are created with just a few clicks of the
computer mouse.
The last method we will discuss is laser engraving, which etches the
design into the material with the use of a laser beam rather than a
sharp tool or stylus. The design is translated into numeric instructions
through the use of a computer program. Some of the benefits of laser
engraving are the quickness with which an image can be created and the
precise clean lines this method achieves. Some of the disadvantages
include a restricted amount of materials that can be used and a high
price tag. |
