1. SAFETY

1.1. ELECTRICAL SAFETY

WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following: You must check all electrical products,

before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other connectors for wear or damage. You must ensure that the

risk of electric shock is minimised by the installation of appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main

distribution board. We also recommend that a Residual Current Device (RCD) is used. It is particularly important to use an RCD with portable products that are

plugged into a supply which is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting

your Sealey dealer. You must also read and understand the following instructions concerning electrical safety.

1.1.1. The Electricity at Work Act 1989 requires all portable electrical appliances, if used on business premises, to be tested by a qualified electrician, using

a Portable Appliance Tester (PAT), at least once a year.

1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances and the safety of

the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.

1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1.

and 1.1.2. and use a Portable Appliance Tester.

1.1.4. Ensure that cables are always protected against short circuit and overload.

1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none is loose.

1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply to be used and that the

1.1.7. DO NOT pull or carry the appliance by the power cable.

1.1.8. DO NOT pull the plug from the socket by the cable.

1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty item repaired or replaced by a

qualified electrician.

When a BS 1363/A UK 3 pin plug is damaged, cut the cable just above the plug and dispose of the plug safely.

Fit a new plug according to the following instructions (UK only).

a) Connect the GREEN/YELLOW earth wire to the earth terminal `E’. b) Connect the BROWN live wire to the live terminal `L’. c) Connect the BLUE neutral wire to the neutral terminal `N’.

Replacement fuse rating: 5A

d) After wiring, check that there are no bare wires, that all wires have been correctly connected,

that the cable outer insulation extends beyond the cable restraint and that the restraint is tight.

1.1.10. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance plugged into it will

be protected. The cable core section is important and should be at least 1.5mm², but to be absolutely sure that the capacity of the reel is suitable for this

product and for others which may be used in the other output sockets, we recommend the use of 2.5mm² section cable. 1.2 GENERAL SAFETY

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

fig.4

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.

Setting and locking the cutter height. Once the workpiece and cutter are mounted, the cutter can be lowered to the correct position to achieve the desired cut. The spindle shaft vertical movement is 30mm. If this does not bring the cutter into the vicinity of the workpiece the whole head can be moved down the column to achieve the desired cutter position. Adjust cutter and head height as described below. To ensure accuracy during milling the cutter height setting must then be locked as described below. Setting the head height. The overall height of the head on the column can be altered by using the head vertical feed wheel ( see fig.4-2 ). To alter the head height first loosen the two socket cap bolts adjacent to the vertical leadscrew ( see fig.4-3 ). Use the handwheel to move the head to the desired height and tighten the socket cap screws to lock the head in position. Engaging vertical fine feed. The drilling/milling spindle travel is controlled for milling purposes by the fine feed wheel ( see fig.3-14 ). To engage the fine feed wheel push the feed selector knob ( see fig.3-8 ) inwards. This action automatically disengages the rapid spindle feed lever ( see fig.3-17 ). Once the spindle/cutting tool has been moved to the correct height it can be locked in this position by tightening the socket cap bolt on the right hand side of the head ( see fig.4-5 ). Calibrated feed. Each feed wheel has an adjustable calibration ring situated on the feed shaft immediately behind the wheel. The rings can be rotated by hand and set to an adjacent mark in order to execute a cut of a specific depth. The longitudinal feed ring has 31 divisions to one full rotation of the wheel. One segment represents a movement of 0.05mm. The cross feed ring has 50 divisions to one full rotation of the wheel. One segment represents a movement of 0.025mm. The longitudinal feed ring has 36 divisions to one full rotation of the wheel. One segment represents a movement of 0.05mm. Main ON/OFF switch with speed control and emergency shut off. The function switch ( see fig.3-13 ) allows you to select either milling/drilling or cutting on the lathe. The switch has a central OFF position. Set the switch to milling/drilling. Select the direction of rotation ( forward for milling/drilling ) using the forward/OFF/reverse switch ( see fig.3-4 ). Ensure that the variable speed control ( see fig.3-11 ) is set at `0′ otherwise the machine will not start. Connect the machine to the mains power supply. The green power lamp ( see fig.3-2 ) will illuminate. If the light does not illuminate release the emergency off switch by twisting the button clockwise until it jumps up. Rotate the rotary speed switch slowly clockwise. As the knob is turned a click will be heard and the motor will start. As the knob is turned further the speed will increase. Set the knob to the desired speed. Stop modes. There are three `stop’ modes as described below. (A). To stop the machine for a short while and then restart, simply return the rotary speed switch to the `0′ position. When you are ready to restart, rotate the switch clockwise to the desired speed. (B) If the machine is to be left unattended for any length of time, switch the forward/reverse switch to `OFF’ as well as returning the speed switch to `0′. (C) In an emergency hit the large red emergency button which automatically cuts the electrical supply to the machine. Before the machine will start again the rotary speed switch must be returned to the `0′ position and the emergency switch must be released. SETTING UP FOR DRILLING.( Disconnect the machine from the power supply while setting up.) Engaging rapid drill feed. The rapid drill feed is controlled with the lever on the right hand side of the head. ( See fig.3-17 ) The rapid drill feed will not operate if the vertical fine feed wheel used for milling is still engaged. To make the rapid drill feed operative pull the feed selector knob outwards. ( See fig.3-8 ) Mounting the chuck and arbor. If the milling cutter and arbor are currently mounted, remove them by loosening the arbor bolt by two turns and giving it a tap with a rubber mallet. Access the arbor bolt by pulling off the plastic cap 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 milling cutter and arbor until they become loose and can be removed. ( Wear protective gloves.) Insert the chuck arbor into the bottom of the spindle shaft and retain it with the arbor bolt. Do not over tighten. The drill chuck is a shallow taper fit onto the end of the drilling arbor. Using the chuck key open the jaws of the chuck until they withdraw inside the chuck body. Place a piece of wood onto the cross feed bed and position the chuck on it below the spindle shaft. Using the drill feed, wind the spindle shaft down until the arbor enters the chuck. Exert firm but not excessive downward pressure on the chuck to retain it on the arbor. Drill bits. Insert an appropriate drill bit into the chuck and tighten the chuck with the chuck key. Remove the chuck key. Attaching the workpiece. The cross feed bed of the machine has 2 inverted 8mm `T’ slots in it for fixing the workpiece or any vice/clamping arrangement used to hold the workpiece. Altering the height of the head. If the tip of the drill bit is not close enough to the workpiece alter the height of the head on the column as described in section 5.4. Speed control and ON/OFF operation. Refer to Section 5.7 for the operation of the main ON/OFF switch and speed setting. Avoid subjecting drills and cutting tools to excessive strain. Do not apply undue force on the handle in order to cut the workpiece. Maintain a controlled cutting speed through the workpiece. SETTING UP FOR CUTTING ON THE LATHE. ( Disconnect the machine from the power supply while setting up.) The chuck. The chuck is attached to the faceplate with 3 studs and nuts. Check that these fixings are secure before proceeding. The chuck is provided with two sets of jaws for either external or internal holding of objects to be turned. Select and fit the appropriate jaws. Using the chuck key wind out the jaws to their maximum extent at which point they can be pulled out by hand. The thread segments are staggered differently on each jaw and therefore the jaws are numbered 1 to 3. Insert the jaws in sequence beginning with No1 and in an anti clockwise direction as you face the chuck. Hold them under pressure whilst turning the key until they are picked up by the mechanism and start to move towards the centre of the chuck. Check that the three jaws come together correctly at the centre of the chuck. If not, wind the jaws out again and press on the misaligned jaw until it drops into place. Tailstock/centre. Material/stock that is too long to be held in the chuck alone can be steadied by a centre fitted into the tailstock. 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 wheel so that the centre makes contact with the end of the workpiece and lock its position by tightening the tailstock lock.( See fig.3-20 ) Toolrest. Mount the toolrest utilising the `T’ slots in the cross feed table. Insert an appropriate cutting tool into the split carrier and 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. 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. 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. Adjust the crossfeed wheel and longitudinal feed so that the tip of the tool is in the correct position to commence cutting when the machine is turned on. Before turning on check that all fixings holding the tool are tight.

8.1 Starting the machine. Lower the guard over the chuck. (The machine will not start with the guard in the up position.) Check that the

function switch is set to `cutting’.

8.2 Select either manual cutting or automatic feed using the clutch knob. See fig.3-10. ( When selecting autofeed it may be necessary to

rotate the leadscrew hand wheel slightly before the clutch will engage.)

8.3 Select the direction of cut using the forward/reverse switch. When using autofeed ensure that the saddle/cross feed/toolrest are

positioned at the intended start of the cut and that the correct direction has been selected. In general the cut will usually start from the

tailstock direction and progress towards the chuck.

8.4 Turn the machine on using the variable speed control. Rotate the knob clockwise until the desired speed is reached. Refer to section

5.7 for a full description of the on/off operation.

WARNING! The machine should never be left unattended whilst switched on during manual or automatic operation. In particular when

a cut is in progress using autofeed the operator must observe the entire cut and be on hand to switch the machine off as the cutting

tool approaches the chuck or other holding devices. Failure to do this may result in damage to the machine and will invalidate

the warranty.

9.1 Autofeed rate/thread cutting. The machine is supplied with a gear set which gives a cutting rate of 0.05mm per single chuck rotation

when autofeed is selected. ( See fig.7 and the standard gear set up highlighted in the gear ratio table below.) By purchasing the

optional metric thread cutting kit ( Part No.SM2503TCK ) the machine becomes capable of an additional autofeed rate of 0.01mm and

will cut metric thread pitches 0.5/0.7/0.8/0.1&1.25mm as indicated in the gear ratio table.

9.2 Changing gear sets. To set up the machine for a particular thread pitch or feed rate refer to the gear ratio chart for the sizes of Z1,Z2

& Z3 and then identify the actual gears. ( The number of teeth on each gear is moulded into the face of the gear.) Gears Z1 and Z2

are pairs of gears which are a push fit onto a splined sleeve. Ensure that the correct pairs are on the sleeve together according to the

chart.

9.3 Remove the existing gear set. Use a large screwdriver to remove Z1 and then Z2. Use a 4mm hex key to remove Z3. The mountings

for Z1 and Z2 are slotted ( See fig.6 ) to allow the centres of the gears to move to accommodate the differing sizes.

9.4 To assemble the new gear set attach Z3 first and tighten the fixing. As gears Z1 & Z2 overlap attach the `hidden’ gear first. The

attachment slots have a sliding nut positioned at the rear of the plate. Slide the nut into the approximate position required. Screw the

gear into place but leave it loose enough to slide. Attach the final gear to the sliding nut in the other slot and allow the gears to settle

into position. When you are satisfied that the gears are fully meshed tighten the fixings for Z1 and Z2. Close and secure the gear

cover and test run the machine to ensure that the drive train is fully functional.

Ensure the machine is unplugged from the mains power supply before attempting fig.9 any maintenance.

For maximum performance it is essential that the lathe is properly maintained.

Lubricate the machine before every use. Lubricate the bearings at either end of

the leadscrew once or twice during the day if used continuously. Open the gear

train cover to gain access to the left hand bearing. Inject oil into the compound s

slide oilway located on the slide front surface between the two hex socket cap screws. After each use remove all swarf from the machine and thoroughly clean all sufaces. If coolant has been used ensure it is all cleaned from the machine and any collection tray is completely drained. Lightly oil all machined surfaces.

A A A
A

Clean and coat the leadscrews with oil weekly.

Cross slide and saddle adjustment. Adjust the accuracy of the cross feed and

saddle on a monthly basis. Any wear or slack can be taken up by adjusting the

position of the appropriate gib strip. To do this use a hex key and spanner as

shown in fig.8. Adjust the cross feed using the adjusters marked `A’ in fig.9.

Loosen the locking nuts on all four adjusters and screw them in evenly using the

same torque. The slide should now be held firmly. Test by trying to turn the handle

but do not force it to turn.

Now back off each gib screw by a quarter of a turn and tighten the lock nuts. Test again by turning the handle. The

movement should be even and smooth along its whole travel.

If the movement is too slack, screw all the adjusters in by one eighth of a turn until the correct adjustment is attained.

Tighten the lock nuts.

Adjust the saddle in the same way using the three adjusters marked `B’ in fig.9.

Cross slide feed handle. If any stiffness occurs in the operation of the handle it is usually as a result of swarf

lodging between the mating surfaces. Remove the handwheel by undoing the securing screw and pull off the

calibrated collar taking care to retain the small spring plate which sits in a groove beneath the collar. Clean the

parts and reassemble in the reverse order taking care to correctly reposition the spring.
