* The Spring Loaded Engraving Tool is covered by U.S. Patents 6,834,434, 7,093,368 and a pending utility patent application.
1. How much travel does a Spring Loaded Engraving Tool have?
- 0.40".
2. What size letters can I engrave using a Spring Loaded Engraving Tool?
- Generally .085" and larger. (Smaller letters may be engraved with technical assistance from 2L.)
3.
What do I set my Z at?
- Set the Z0 plane at the top surface of the workpiece.
- Set the plunge depth to Z-0.025" for normal engraving on relatively flat workpieces.
- Set the plunge depth deeper if the workpiece tolerances are greater.
4. Why do I rapid into the part, instead of feeding slowly like a rigid toolholder?
- Feeding slowly into the workpiece will cause the toolbit to drill down into the material. This may cause the tip of the toolbit to break prematurely. We recommend plunging at a feedrate of 200ipm or more.
- Plunging the tool rapidly into the workpiece instead of feeding slow reduces the overall cycle time of the engraving job and increases the life of the engraving toolbit.

5. How do I control the engraving depth?
- By adjusting the spindle speed and feedrate (speeds and feeds). The faster the feedrate, the less deep the tool will engrave. The slower the feedrate, the deeper the engraving.
- Spring Loaded Engraving Tool Feedrates are approximately 3–5x faster than using a rigid tool.

6. How deep will the engraving be?
- When engraving aluminum with a standard toolbit and a light spring, approximately 0.005" - 0.010" per pass.
- Steel, stainless steel, and harder materials - approximately 0.003" - 0.005" per pass using a Tough Tip Engraving Tool.
- Greater depths per pass can also be obtained with stronger springs.
- The engraving obtained depends greatly on the toolbit used. 2L produces toolbits for different materials and for both shallow and deeper engraving.
7. How do I get a deeper engraving?
- Make a second pass (remember: engraving with a Spring Loaded Engraving Tool is much faster than with a rigid toolholder, so making multiple passes is still faster than using a rigid tool).
- Slow down the feedrate. Slower feedrates give the tool more time to cut and produces deeper engraving. (Or increase the spindle speed if the machine is capable - this has the same effect and won’t alter the cycle time.)
- Use a sharper toolbit (Special toolbits are available for digging deeper in steels and aluminums).
- Use a stronger tension spring (stronger springs wear tools more quickly).
Depths of up to 0.025" per pass can be obtained in steel but with a reduced
tool-life.

8. When do I need a Depth Control Nosepiece?
- Typically only when engraving very soft materials, such as plastics, or if you require very precise engraving depths.
- The nosepiece is adjustable in 0.001" increments.
