BANDSAW OPERATIONS - OD1646 - LESSON 1/TASK 1
An attachment for the metal cutting bandsaw twists the blade 30, or 90, so
that stock which normally could not be cut because of insufficient clearance
of the sawing machine column can be successfully cut.
Other attachments
permit the use of band files and polishing bands in place of the bandsaw
blade.
Adjustable guides for holding and feeding workpieces are also
provided.
The
machine
has
a
power feed
mechanism operated
by
counterweights. Forced air for chip removal is supplied by an air pump in
the base of the machine.

Horizontal Bandsaw.
The typical metal cutting horizontal bandsaw
machine (figure 2 on the following page) is a floor-mounted machine used for

The
material to be cut is mounted in a vise attached to the bed of the machine.
An electric motor drives the bandsaw blade through a belt and pulley
arrangement from which three speeds may be obtained.
