42 Sabre Owner’s Guide
Follow these guidelines when choosing sacrificial material.
♦
Select a sacrificial material with a density similar to the material being cut.
♦
Medium Density Fiberboard (MDF) is a good sacrificial material since it is porous
enough to allow the vacuum to draw through it and hold the workpiece in place.
♦
The best sacrificial materials are acrylic or pressed boards such as chip board and
Masonite®. Acrylic is recommended over pressed board that contains glue. Glue is
abrasive and can wear out cutter tips.
♦
Remove the protective paper from acrylic before using it as sacrificial material.
The material being cut determines how you attach material to sacrificial material. You can use
double-sided tape, high-tack transfer tape, low-tack transfer tape, or spray adhesive. These
products are available from your Gerber distributor, as well as through most industrial and
office supply distributors.
Material hold down guidelines
Follow the general guidelines in this section. You may wish to adjust your procedures as you
gain experience.
Wood and wood products
Examples of different kinds of wood that can be routed using the Sabre include MDF (medium
density fiberboard), plywood and other laminated woods, pine, poplar, redwood, cedar, oak,
teak, walnut, cherry, and others.
Note: Use material that is as flat as possible. Holding warped material to the table is difficult.
To mount wood and wood products
1
Place the wood on the table in the desired location.
2
Use the vacuum shroud pressure foot assembly to assist in chip removal as well as
extra holddown while cutting.
3
If using the T-Vac, try to use the vacuum holes to the best possible advantage. Keep
any unused valves turned off. Block off any holes behind the material with a piece of
non-porous material. If not using the T-Vac: Using the table clamps, place the clamps
at three corners of the material leaving the start position corner free of clamps.
4
Initialize the tool from the material surface to cut into the material or initialize from
the table to through cut (also called
cut to mask
).
5
When finished cutting, you will have a thin web of material remaining to hold the
shapes being cut to the material. If you apply a paper mask to the back of the material,
you automatically cut to the mask when you initialize from the table.
Metals and hardwood
♦
Use double-sided high-tack tape to secure the material directly to the table. This tape is
not affected by mist coolant and is suitable for securing metal. Cutting metal requires
high cutting forces.
