SETTING UP
Note:
These machines should only be used
for hole boring/drilling whilst attached to the
work-piece by the electromagnetic base.
EVOMAG75 can also be used for tapping holes
if it is fitted with a suitable clutched chuck (not
supplied). Follow the instructions supplied
by the chuck manufacturer when conducting
tapping operations.
WARNING:
Ensure that any operator has
read and understood this manual. Attention
should be drawn particularly to the section on
intended and prohibited uses of this machine
contained within this manual.
WARNING:
These machines are intended
for use in any position, but only if the
electromagnet is in full working order and has
sufficient hold on the work-piece.
• Extra care and operator vigilance should be
exercised if the machine is to be used on a
vertical surface or in an inverted position.
• The safety chain or strap must be securely
attached to the work-piece and preferably pass
through the carrying handle of the machine.
• The safety chain/strap must be secured to
both the machine and to the work-piece in
such a way as to ensure that the machine
cannot become completely detached from
the work-piece in the event of magnet
deactivation.
• The safety chain/strap should not be used
as an alternative to the magnet for clamping
purposes.
• Have the workplace setup checked by the
person responsible for workplace safety
(Safety Officer) before cutting operations are
commenced.
COOLANT/LUBRICANT DELIVERY
Note:
It is recommended that high quality
water soluble oil is used as other coolants/
lubricants may have a high viscosity and not
flow easily to the cutter.
• Fill the coolant tank with suitable coolant/
lubricant liquid.
• Ensure that the ON/OFF tap is in the ON
position.
• Ensure that the work-piece is flat, clean
and free from any rust, coatings or other
contamination.
• Position the machine on the work-piece and
energise the electromagnet by operating the
red rocker switch.
• Check that the machine is firmly attached to
the work-piece.
• Loosen the coolant tank screw top slightly. This
will prevent a vacuum being created in the tank
as fluid is delivered to the cutter.
• Gently squeeze the coolant tank to begin the
delivery process.
• Lower the cutting head towards the work-
piece until the cutter teeth are just about to
touch the work-piece, and the pilot pin has
been pushed up into the cutter.
• Raise the cutting head.
• Repeat this process until coolant/lubricant
fluid is flowing freely onto the work-piece.
• Adjust the ON/OFF Tap to give the fluid flow
required.
Note:
In some circumstances and when the
machine is orientated in some ways, liquid
coolant delivery may not be possible. If this is
the case use a suitable ‘cutting paste’ applied
to the cavity of the cutter and directly to the
work-piece before cutting operations begin.
The ‘cutting paste’ may need to be replenished
during the cutting process.
WARNING:
Only replenish ‘cutting paste’ after
the motor has been switched ‘OFF’ and it and
the cutter are completely stationary.
GENERAL GUIDANCE
HOLE CUTTING WITH ANNULAR CUTTERS
Note:
EVOMAG28 is fitted with a 10 Amp 230V (5 x 20mm)
Surge Fuse. This is located in a fuse holder found in the
machine’s switch panel.
(Fig. 13)
If the machine fails to operate,
check the fuse. If it has “blown”, replace it with an identical type.
• Correctly position the machine on the work-piece, with the
electromagnet energised and the safety chain/strap securely
in place.
• Check for sufficient coolant/lubricant flow at the cutter.
• Start the motor by pressing the green push-button located on
the machine’s switch panel.
• Using the feed handle, slowly lower the cutting head until the
cutter makes contact with the work-piece.
• Continue to apply only sufficient gentle pressure to allow the
cutter to cut freely through the work-piece.
• Depending upon the thickness of the work-piece, it may be
beneficial to periodically raise the cutter and clear any build up
of ‘swarf’.
WARNING:
Only clear ‘swarf’ from a cut with the cutting head
raised and the arbor, cutter and motor completely stationary.
• Continue the cut to completion and then turn ‘OFF’ the
machine’s motor.
WARNING:
On completion of the cut the pilot pin will eject
the material ‘slug’. This ‘slug’ will be very hot with very sharp
edges. Make adequate arrangements to safely contain or ‘catch’
an ejected slug thereby ensuring the safety of any colleagues
working nearby. Consult the site Safety Officer for extra specific
guidance.
Use protective gloves if the ‘slug’ requires handling. If the ‘slug’
fails to be ejected from the cutter, this could be caused by the
slug becoming ‘twisted’ inside the cutter. To release the ‘slug’,
lower the cutter onto a flat area of the work-piece. This will
‘square-up’ the ‘slug’ and allow it to be ejected.
INSTALLING A 3 JAW CHUCK
EVOMAG 28
A three (3) jaw chuck (part HTA153) can be fitted into the main
drive spindle of this machine. This enables EVOMAG28 to take
standard twist drills up to Ø1/2in.
WARNING:
Ensure that the machine is disconnected from the
mains power supply when installing the 3 jaw chuck.
