If the machine requires mounting to the floor, is the floor solid
andlevelandisabletoallowsecurefixing.
Consideration must also be given to the length and width of the
materialtobemachined.ensuringthatthereisenoughspaceat
either end and around the machine, to accommodate the largest
pieceofmaterialtobemachinedsafely.
ASSEMBLY
Lift out the base plate, remove the protective paper and place
thebaseplateonaworkbenchorthefloor.
Locate the chuck, chuck key, three handles, four bolts, two
hexagonal keys, telescopic guard and drift and place to one
sidefortimebeing.Liftouttheworktable,headstockandmotor
assembly and the column, remove the protective paper and
placethemontotheworkbench.
LOCATING THE MACHINE
MOUNTING THE BASE PLATE (PIC. 2)
Select a suitable location for the drill, either on a workbench
oronthefloorformountingthebaseplate.Beawareoftable
legs and anything which might reduce access to the underneath
of the workbench if bench mounted.A suitable mains supply
socketmustalsobeaccessiblefortheplug.
Ifthedrillistobebenchmounted(ModelNBD450-2-NBD450-
NBD350),locatethebaseplateintheselectedposition.Select
four suitable length bolts, washers and nuts (not supplied).
Using the base plate as a template drill four holes through the
workbench(Pic.2)(2.1).Boltthebaseplatetothebench.Do
notovertightenasthiscouldcrackthecastbaseplate.Thedrill
canbesecuredtothefloorusingthesameprocedure.
FITTING THE COLUMN (PICS. 3 & 4)
On the bench mounting model the column support is pre
pressed onto the column. On the floor mounting model slide
the column support onto the column until it is fully located and
tightenthetwogrubscrewssecurely(Pic.3).
Alignthefourthreadedholesonthebaseplatewiththecolumn
supportholes(Pic.4).Securewiththefourbolts.Donotover
tighten as this could crack the cast base plate and column
support.(NBD350:threebolts)
FITTING THE RACK AND PINION GEAR (PICS. 5 & 6)
Locatethetablesupportassembly(Pic.5)(5.1)andtheworm
gearshaft(Pic.5)(5.2).Offerthewormgearshaftthroughthe
top of the table support assembly and locate the shaft through
thebushing(Pic.5).
Note that the end of the shaft has been machined with a flat,
which allows the winding handle to be located and secured in
place.Locatethewindinghandleontotheshaftandsecurein
placeusingthegrubscrewandtightenusingahexkey(Pic.6).
FITTING THE TABLE SUPPORT (PICS. 7 TO 10)
NOTE:for ModelNBD1500thetable ispre-fittedto thetable
supportassembly.
CAUTION:YOUMAYNEEDANASSISTANTFORTHENEXT
PROCEDURE
Lower the rack, into the table support assembly ensuring that it
engageswiththewormgear(Pic.7).Makesuretheendofthe
rackwithoutteethisuppermost.
Lower the table support assembly onto the column until the
racklocates into thecolumnbase(Pic. 8).The assembly will
slideeasily into position so do not useforce.Lower the rack
upper retaining collar onto the column and locate it over the
upperendoftherack(Pic.9.1).Tightenthegrubscrewwith
thehexagonalkeysupplied(Pic.9)(9.2).Makesurethetable
supportassemblytogetherwiththerackwillrotate360°.Ifthe
rotation is stiff or if the rack prevents smooth rotation slacken off
the grub screw in the upper retaining collar, adjust the position
oftheupperretainingcollarandre-tightenthegrubscrew.
Check the up and down motion of the table support assembly by
windingthehandle.Theactionshouldbesmoothoverthefull
rangeoftravel.Locatethetableassemblysecuringhandleand
screw it into the threaded hole at the rear of the table support
assembly (Pic.10). This handle is used to lock the table into
position after the desired height and 360° rotation positions
havebeenachieved.
FITTING THE TABLE (PIC. 11)
Models NBD450-2- NBD450 -NBD750 Only
ForModelNBD1500thetableispre-fittedtothetablesupport
assembly.
Take the table and offer it to the table support assembly locating
thestubshaftintothetableclamp.Locatethesecuringhandle
and screw it into the threaded hole in the table clamp and tighten
(Pic.11).Thiswillsecurethetableintoposition.
Caution: thisoperationrequirestwopersons.
FITTING THE HEAD STOCK AND MOTOR
ASSEMBLY (PIC. 12)
Locate the two grub screws in the side of the head stock and
motorassembly.Usingahexagonalkeyslackenthetwogrub
screws.Lifttheheadstockandmotorassemblyandloweritonto
thecolumn.Makesurethatitslidesdownandlocatesfullyon
thecolumn.Positiontheheadstockandmotorassembly,with
theStop/Startswitchfacingthefrontandalignedwiththebase
plate.Tightenthetwogrubscrews(Pic.12)tosecurethehead
stock and motor assembly into place. Retain the hexagonal
keysforfutureadjustments.
FITTING THE HAND FEED HANDLES (PIC. 13)
Locateandinstallthethree,handfeedhandles.Simplyscrew
the handles into the three threaded holes located in the feed
shaftboss(Pic.13)(13.1).Makesurethatallthreehandlesare
tight.
FITTING THE TELESCOPIC GUARD
NOTE: on models NBD450-2 - NBD450 - NBD750 the
telescopic guard must be fitted before fitting the chuck. For
model NBD1500 the telescopic guard can be fitted either before
orafterfittingthechuck.
NBD350: The telescopic eye guard is partially assembled onto
themachine.Positiontheclearplasticshieldintotheredcollar
andsecureinplacewiththetwosmallcrossheadscrews(Pic.
