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.
