Common applications for deep metal engraving are gun engraving and parts engraving. When engraving into guns or something that calls for a specific depth, you would want to use a carbide tool as opposed to a diamond tool. A carbide tool will allow you to engrave deeper into the metal. Examples include color filling, firearms or any type of metal requiring a specified depth.
As long as you can secure the material while engraving, you can engrave it. An example of this would be engraving on gun receivers. As long as you have a fixture holding the part down, you can engrave it. You would, however, need a machine that gives you the clearance, taking into account the gun and fixture. Generally a 7” clearance is enough; however, there are metal engraving machines with a 10” clearance if you need the extra space.
When engraving metal with a carbide tool, you must slow down the feed rate and increase spindle rotation. Sound complicated? Don’t worry! When using Vision software (Vision 9), there are preset settings for all the common materials being engraved of which one of them is deep metal engraving. You simply select the type of engraving you are doing and the software will automatically set all of the feed rates for you.
Here are some points on using deep metal engraving machines:
– Feed settings for carbide tools are much slower and tool life is also shorter than a diamond tool
– Carbide tools can be re-sharpened 4 to 5 times at a cost of $6 to $8 dollars per sharpening
– Software comes with tool settings application chart for auto setting of tool feed rates by application
