Magnetic base
– before every operation the magnetic base should be checked to make sure
that the base is flat and there is no damage present. An uneven magnet base will cause the
magnet not to hold as efficiently and may cause injury to the operator.
Adjustment of slide and bearing bracket alignment.
An essential requirement of the machine is that the slide can move in a smooth and controlled
manner, free of lateral movement and vibration.
This situation can be maintained by periodic adjustment of the slide and is accomplished in the
following manner:
1.
Place the machine in an upright position and, by means of the capstan, raise the slide to
its highest position. Clean the brass gib strips and apply a small amount of light machine
oil to the wear surfaces.
2.
Now lower the slide back to its lowest position. Bring the slide into the center of the
dovetail slide housing and loosen screws thus allowing free movement of the arbor
support bracket.
3.
Commencing with the middle screws, gently feed in all the screws until slight resistance
is encountered.
4.
Operate the slide up and down a few times to test the movement and make any further
necessary adjustments. Try to ensure that all the screws are exerting a uniform pressure
on the slide from top to bottom. A perfectly adjusted slide will operate freely up and
down without any sideways movement.
5.
Now raise the slide to its highest position. Slightly undo the arbor bearing bracket and,
using fingers only, tighten the screws.
6.
Place the machine on a steel plate, connect to power supply and switch on the magnet.
Start up the motor. If the arbor is incorrectly aligned, the arbor support bracket will be
seen to oscillate. Make any necessary further adjustments to the bracket to ensure
correct alignment of the spindle and finally tighten the screws using a spanner. Lastly
tighten the arbor bearing bracket.
Check machines grease.
The gearbox grease should be checked once a month to ensure all moving components are
covered to prevent wear. The grease should be changed at least once a year to ensure you gain
the best from your machine.
Check Armature of the machine.
This should be checked at least once a month to check that there are no visual signs of damage
to the body or to the commutator. Some signs of wear will be seen on the commutator over a
period of time but this is normal (this is the part that comes into contact with the brushes)
however, if there are any signs of abnormal damage the part should be replaced.
