Cutting and advance speed
The cutting speed (m/min) and the advance speed (cm2/min = area traveled by the disk teeth
when removing shavings) are limited by the development of heat close to the tips of the teeth.
•
The cutting speed is subordinate to the resistance of the material (R = N/mm
2
), to its
hardness (HRC) and to the dimensions of the widest section.
•
Too high an advance speed (= lowering of the saw frame) tends to cause the disk to deviate
from the ideal cutting path, producing non rectilinear cuts on both the vertical and the
horizontal plane.
The best combination of these two parameters can be seen directly examining the chips.
Long spiral-shaped chips indicate ideal cutting.
Very fine or pulverized chips indicate lack of feed and/or cutting pressure.
Thick and/or blue chips indicate overload of the blade.
CHOOSING A SAW BLADE
Baileigh Industrial offers a wide selection of tooth styles for various cutting applications. Please
phone Baileigh Industrial to have one of our technicians assist you in selecting the proper band
saw blade for your cutting applications.
A general purpose blade is furnished with this band saw.
To achieve a quality, economical, and efficient saw cut, the following points must be taken into
consideration:
•
Type of material being cut (ferrous or non ferrous)
•
Material hardness and physical dimensions
•
Blade descent rate
•
Longitudinal speed of blade
•
Blade tooth profile
Choose a tooth pitch that is suitable for the workpiece. Thin walled profiles, including tubes and
pipes require close toothing. At least 3-6 teeth should be in contact with the material while
cutting. Large solid or transverse sections require widely spaced toothing to allow for greater
volume of chips and better tooth penetration. Soft materials such as plastics, light alloys, mild
bronze, Teflon, etc. require widely spaced toothing to avoid clogging.
