Cutting Speed:
The blade is rotating at approximately 3700 RPM. When moving the blade through the material, the blade must
NEVER
be allowed to dwell in the work. If fine finishes are required;
1. Use a sharp blade.
2. Use a
constant, even pressure
when cutting through material.
Clamping and Work Slippage:
The work must never be allowed to move or vibrate as it is being cut. When the work is positioned against a
stop, it must be clamped either by hand holding or by pneumatic air clamps. Never allow unclamped work
between the blade and the stop, as the blade can grab the material and throw it—thereby causing damage to the
blade, the machine, and possibly harming the operator. CTD offers both Horizontal and Vertical Clamps. The
Horizontal Clamp pushes the material forward against the front fence. Vertical Clamps hold the material down,
against the table base. Both clamps are offered as optional extras and are highly recommended. The clamps
are actuated at the same time as the saw heads by depressing the Foot Valve. Check your material for squareness,
using a 90
°
square. Material that is out of square will move when it is cut, thereby causing irregular mitres. See
“IRREGULAR MITRES”, Page No. 16. Additional tooling may be needed. Consult factory for information.

Cutting Wood:
While wood is generally soft and simpler to cut than aluminum, it requires that the material be held in place
as the blades pass through the material. CTD suggests using a Carbide Blade with an Alternate Top Bevel
(ATB) for lighter wood sections and picture frame mouldings. This type of blade gives the finest of finishes.
No
ONE
blade will cut all material perfectly. High laquers or mica mouldings require a special modified blade
for best results. Consult factory.
Never use a wood blade to cut aluminum,
as it will chip and fracture the
carbide tips of the blade.
Cutting Plastic:
Plastic can be cut as easily as wood on the D45X models. However, because of its elastic properties, the material
can deflect as the blades pass through. Therefore it is important to clamp the material as close as possible to the
blade and support it by use of fixtures. CTD offers special 45
°
clamps for this application. Additional tooling may
be required. Special carbide blades are avialable for cutting platics.
