6.0 MACHINE FEATURES

Figures 1 and 2 depict the main features of the Model EHB-
8 Horizontal Cut-Off Bandsaw. The machine consists of a
machine base onto which is installed a saw head.

6.1 MACHINE BASE

The machine base consists of a coolant collection pan
mounted on two panels that form the legs of the machine.
A shelf is provided under the collection pan that supports a
coolant tank.
The machine bed mounts on the top of the collection pan.
The bed supports the vise and the vise-tightening lead
screw.
The coolant tank is equipped with a pump/motor assembly.
The pump/motor circulates coolant through tubing to cool
and lubricate the saw blade, the blade guides, and the
workpiece.
A drainpipe is provided to connect the collection pan to
the coolant tank. A screen is provided in the collection
pan to screen-out cutting debris as the coolant drains into
the coolant tank. Coolant is added to the tank by pouring
coolant into the collection pan. The tank is easily removed
from its shelf for cleaning and maintenance.

6.2 SAW HEAD
The saw head (Figure 2) consists of a drive motor, drive
pulleys, gearbox, blade wheels, blade guides and supports,
control panel, blade tension/blade tracking mechanism,
wire brush, and the saw blade.
The drive motor is mounted on a pivoting plate that swings
outward to provide drive belt tension. The motor is fitted
with a step pulley; the drive belt connects to a second step
pulley that is mounted on the input shaft of the gearbox.
A speed-reducing gearbox is mounted on the back side of
the blade wheel box on the right side of the machine. The
blade wheel (drive wheel) is installed on the output shaft of
the gearbox.
A second blade wheel is located in a blade wheel box on
the left of the machine. The blade wheel (driven wheel) is
mounted on a shaft that is part of the blade tension/tracking
mechanism. The blade tension mechanism is used to
tighten the saw blade on the blade wheels.
The mechanism also has adjustment screws that enable
the saw blade to "track" evenly on the blade wheels. The
adjustment screws change the angle of the driven blade
wheel shaft so the wheels are aligned. Tracking adjustments
are generally made after the saw blade is changed but may
be required periodically due to wear over time.
