High Speed Materials; Low Speed Materials; Sanding And Linishing - Burgess BK3 Specification And Operating Instructions

High speed materials .
With the machine set at high speed it is
suitable for profile cutting and cross cut-
ting of both hard and soft woods. At the
higher speed you will findthewoodwill cut
very easily and all you refforts can be
directed towards guiding the work past
the blade. On thicker sections of timber
(over 15mm) where a long cut along the
grain is to be made, it may be desirable to
use the lower speed to obviate the
possibility of stalling the motor.
Low speed materials
The low speed is used primarily for steel
and other metals, but It is also advisable to
use t~e slow speed when cutting
olastrcs over Smm thick.
If
a high speed is
used when culling thick plastic material
substantial amounts of heat may be .
generated which will tend to weld the plas-
tic together beh ind the blade a nd even-
tuallycause the machine to stall.
Sanding and lii'lishing
This is also carried outat the higher speed.
These belts are fitted to the machine in the
same way as the blade. However it is
advisable that the top and bottom blade
guide assemblies be removed completely
to avoid any damage to these items. When
fittin9 the finish ing belt ensure that the lap
joint In the belt is as shown in the sketch,
so as to avoid tearing the belt.
Whilst the belt can be used for finishing
operations without having any support to
the back taceot the belt, it is far more
effective if sorndoressure is applied to this
back face by
means
of a suitably shaped
piece of wood or similar material.
