6. 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. PROCEED TO SECTION 6.17 FOR SETTING UP FOR CUTTING ON THE LATHE WARNING!Beforeoperatingthedrilling/millingmachineensureyouarewearingapprovedsafetygogglesandglovestoprotectyou from swarf and metal particles. If using cutting oil or coolant a face mask may be necessary to avoid breathing any vapour generated.

9 Ensure that all other safety instructions in chapter 1 are followed carefully. 6.1. SETTING UP FOR MILLING (Disconnect the machine from the power supply whilst setting up.) The machine is supplied without

milling cutters. Contact your local Sealey Stockist for a full range of accessories. 6.2. MOUNTING THE CUTTING TOOL If the drill chuck and arbor are currently mounted, remove them by the following method. Access

thearborboltbypullingofftheplasticcap(fig.4.1)whichcoversthetopofthespindleshaftandplacean8mmspannerontotheflatsat the top of the shaft. Insert a rod into the hole in the side of the spindle shaft (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.

6.2.1. 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.

6.3. ATTACHING THE WORKPIECE Theworkpiecewillbemountedtothecrossfeedtableutilisingthe8mmTslotsprovidedforthetoolrest. 6.4. SETTING AND LOCKING THE CUTTER HEIGHT Once the workpiece and cutter are mounted, the cutter can be lowered to the

6.19. TAILSTOCK/CENTREMaterial/stockthatistoolongtobeheldinthechuckalonecanbesteadiedbyacentrefittedintothetailstock. Once one end of the workpiece is fixed into the chuck loosen the two socket cap screws holding the tailstock and slide it up to the unsupported end of the workpiece so that the centre is close to it. Tighten the tailstock socket cap screws. Now wind the tailstock wheelsothatthecentremakescontactwiththeendoftheworkpieceandlockitspositionbytighteningthetailstocklock,(fig.3-20.)

6.20. TOOLRESTMountthetoolrestutilisingtheTslotsinthecrossfeedtable.Insertanappropriatecuttingtoolintothesplitcarrierand mount the tool and carrier into one side of the toolrest. Now make any necessary adjustments to the position of the toolrest and carrier to allow the cutting edge of the tool to be correctly presented to the workpiece. The tool should be cutting in a plane that passes through the centre axis of the workpiece or just below it.

6.20.1. The angle of the tool when viewed from above may be changed by loosening the central holding bolt on the toolrest and twisting the whole rest on the bed to obtain the desired angle.

6.20.2. One side of the toolrest will clamp the tool and carrier parallel to the bed of the machine. On the other side of the toolrest the tool and carrier rests on a contoured block which allows the tool to be inclined upwards or downwards by a few degrees. The angle of tilt is controlled by adjusting the two socket cap bolts which bear on the tool carrier.

6.20.3. Adjust the crossfeed wheel and longitudinal feed so that the tip of the tool is in the correct position to commence cutting when the machineisturnedon.Beforeturningoncheckthatallfixingsholdingthetoolaretight.

6.21. STARTING THE MACHINE Lower the guard over the chuck. (The machine will not start with the guard in the up position.) Check that thefunctionswitch(fig.3-13)issettocutting.
