♦ When cutting rough textured wood, use both double-sided high-tack tape and spray
adhesive.
To mount thick aluminum or brass thicker than .125" (3.18 mm) without T-Vac
1 Use 1/8" (3.18 mm) acrylic sacrificial material.
2 Use double-sided high-tack tape to hold the material onto the sacrificial material. Be
sure to use aggressive tape to keep the shapes from shifting when they are cut free of
the material.
3 Apply the tape so that all shapes are held securely to the sacrificial material.
4 Use clamps to secure the aluminum/acrylic assembly to the table.
To mount thick aluminum or brass thicker than .125" (3.18 mm) with T-Vac
Note: Do not use sacrificial material.
1 Make sure the material is relatively flat or that the T-Vac can accommodate any warp
and hold the material securely.
2 Set up the job to leave a slight web (.005" - .008" (.127 mm - .203 mm)) uncut to keep
the shapes in place as they are cut free of the material. Use the ADJ DEPTH function
key to adjust the depth during cutting as described on page 32.
Note: To remove the shapes from the aluminum material, remove the material from the table
and tap each shape with a rubber hammer. Deburr each shape with a file or burr tool.
To mount thin aluminum or brass and other thin metals less than .090" (2.29 mm)
Whenever cutting aluminum, holding down the material stiffly provides better cut quality and
edge finish. Using the method described below will allow you to hold the aluminum stiffly to
the sacrificial material. You will cut all the way through the aluminum into the sacrificial
material leaving a clean edge. This also allows removal of the cut pieces from the sacrificial
material without bending the aluminum.
Note: 6061-T6 aluminum will give the best results.
1 Use 1/8" (3.18 mm) acrylic sacrificial material cut the same size as the metal. Remove
the backing paper from one side.
2 Apply high-tack transfer tape to the back side of the metal. Be sure to squeegee the
tape down well to achieve a good bond to the metal.
3 Apply high-tack spray adhesive (such as 3M Super 77) to the side of the acrylic
without backing paper, as well as to the taped side of the metal. Follow the
manufacturer's application instructions.
4 Allow the spray to become tacky, then apply the material to the acrylic.
5 Use clamps or the T-Vac to hold down the aluminum/acrylic assembly.
