5. SET- UP AND OPERATION
It is assumed that the operator has some experience of machining practice and therefore these instructions are intended only to
describe the features of the machine. If you have no experience of machining it is recommended that you undertake a training
course or seek advice from an experienced source.
WARNING! Before operating the drilling/milling machine ensure you are wearing approved
safety goggles and gloves to protect you from swarf and metal particles. If using cutting oil or
coolant a face mask may be necessary to avoid breathing any vapour generated. Ensure that
all other safety instructions in chapter 1 are followed carefully.
5.1
SETTING UP FOR MILLING. ( Disconnect the machine from the power supply whilst
setting up.) The machine is supplied without milling attachments. Contact your local Sealey
dealer for a full range of accessories.
5.2
Mounting the Cutting Tool. If the drill chuck and arbor are currently mounted, remove them
by the following method. Access the arbor bolt by pulling off the plastic cap ( See fig.4-1 )
which covers the top of the spindle shaft and place an 8mm spanner onto the flats at the top
of the shaft. Insert a rod into the hole in the side of the spindle shaft ( See fig.4-4 ) to prevent
it turning and loosen the arbor bolt by two turns. Give the arbor bolt a sharp tap with a rubber
mallet in order to release the arbor from the internal taper. Continue to unscrew the arbor bolt
by hand whilst supporting the drill chuck and arbor until they become loose and can be
removed.
5.2.1
Select the cutting tool for the work in hand and the appropriate arbor or collet.
Wear protective gloves at all times especially when handling the cutter. Introduce the
cutter assembly into the spindle sleeve and hold it in place whilst the arbor bolt is tightened
by hand. Insert a rod into the hole in the side of the spindle shaft to prevent the spindle
rotating and tighten the arbor bolt with a spanner ( do not overtighten ).
Remove the rod and replace the plastic cap.
5.3
Attaching the workpiece. The workpiece will be mounted to the crossfeed table utilising the
8mm 'T' slots provided for the tool rest.
