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.
