Green light stays on.

l) Turn the Forward/Off/Reverse switch to Off position (Clicks Off) all lights are now off. m) Select Forward on the Forward/Off/Reverse switch. n) Turn the Speed Control Switch On and advance until the Chuck starts to rotate. o) Turn the Forward/Off/Reverse switch to Off position, check that the machine stops, turn

the Forward/Off/Reverse switch to Forward, check that the Green light comes on and the Amber LED comes on and the machine does not start. Turn all switches off (All lights are off).

p)Turn Forward/Off/Reverse switch to Forward. q) Turn the Speed Control Switch On (Clicks On), advance until the chuck starts to rotate. r) Over a period of approximately 5 minutes advance the speed in stages to maximum, run at

maximum for at least 2 minutes, check that there is nothing untoward, (no excessive vibration, speed progression is smooth etc.). Stop the spindle and change the gear selector to H (High), carry out the previous check. Repeat the checks with the motor set in reverse. s) If all the above checks are correct, stop the spindle, (turn the speed control to zero and select Off on the direction selector switch. Ensure the fine feed control is disengaged, using the ʻcoarseʼ feed lever handle, exercise the quill up and down, check the movement is smooth and precise. t) Select the fine feed function, (if necessary ʻjoggleʼ the feed hand to enable the gears to mesh). Raise and lower the quill using the fine feed control. Check the movement is smooth and precise, there are no hard spots and the feed doesnʼt bind up. u) Ensure the head lock clamp is loosened and exercise the rise and fall, driving the head up and down the tool post. Check the movement is smooth and tight. Leave the head fairly well down the tool post for the next check. v) Loosen the tilt clamp bolts, and tilt the tool post to the left and right, clamp the tool post in an arbitrary position and tighten the clamp bolts. Check that the tool post remains locked in place. w) If all the above checks are correct, your mill is now ready for use.

PARTS IDENTIFICATION AND DESCRIPTION

Please take some time to identify the various parts of your machine so that you are familiar with the terminology we will use to enable you to set up and operate your Mill safely and correctly.

Main tool post This is the column of the mill, it is an 65 x 50 bar with a dovetail

slide machined on the front onto which the milling head is mounted, the lower part is the circular ʻbossʼ for the tilt assembly. On the left side of the post a scale, graduated in mmʼs, is mounted to read against an adjustable pointer mounted on the head casting.

Rise and fall The Rise and Fall drive screw is anchored in a machined housing

at the top of drive screw the main tool post. It has a wheel and rod handle keyed to the shaft to enable the screw to be turned. It is fed through a threaded dog that is bolted to the head casting allowing the head to be moved up and down. Viewed from above the drive screw is turned clockwise to raise the head and anti-clockwise to lower it.

Tilt housing The tilt housing is mounted to the base casting using 4 bolts. The

tilt ʻbossʼ of the main tool post is mated to the housing and clamped by a urther 4 bolts. The main tool post can tilt 45 (degrees) from the vertical either left or right. There is an adjustable pointer and a scale mounted on the housing to give an indication of the amount of tilt that has been applied.

Milling head This is the ʻmilling machineʼ and the descriptions of its

various parts and components are detailed as follows:-

Milling head The main casting to which all the components are attached. The casting head has a dovetail housing machined at the rear, which allows

the casting to be fitted to the Main Tool Post. The left side of the dovetail slide is fitted with a gybe strip to maintain the fit.

Head clamp Located between the gybe strip adjusters and locknuts is an handled

bolt that clamps the gybe strip against the slide to effect a locking action for the rise and fall of the head.

Rise and fall An ʻLʼ shaped casting that is threaded to accept the rise and fall drive screw dog drive screw, and is driven along the thread when the screw is

turned. As it is bolted to the milling head, the head will therefore follow its movement as it is being driven.

Motor and The motor and gearbox assembly are mounted above the main gearbox head casting at the top of the arbor sleeve. The motor drive is

geared through to the spindle with an intermediate 2:1 gearbox.

PARTS IDENTIFICATION AND DESCRIPTION

Gear change The gear change knob allows the selection of the high or low ratio knob of the gear train. The speed of the spindle is then governed by the

speed control on the motor panel. (You may have to ʻjoggleʼ the chuck/tool to aid the meshing action).

Motor A 220V d.c. motor rated at 150W.

Feed Handle Lever handle that is used to drive the quill (and hence the chuck or

the tool) up and down. The boss of the handle is fitted to the end of a ʻsplinedʼ gear shaft. This ʻsplinedʼ gear is, in turn, engaged in the rack cut into the quill body. There is a counter balance spring in the arbor and sleeve assembly, giving a more controlled ʻfeelʼ during drilling operations. It also retracts the quill when drilling is completed.

Fine feed The fine feed assembly floats around the splined gear shaft that assembly drives the quill up and down. When the action of the fine feed

mechanism is required; pulling out ʻengageʼ knob of the fine feed control meshes the gearing (you may have to ʻjoggleʼ the feed handle to aid the meshing action) between the splined shaft and the fine feed control shaft; this enables the spindle to be driven by the fine feed control wheel with greater precision. Behind the boss of the fine feed control wheel handle is a graduated ring (thimble) so that the movement of the quill can be measured. The thimble is held to the drive shaft by friction, and can be pre-positioned to establish a predetermined start or stop dimension.

Motor control Power On LED panel Green LED that indicates that power is available to the motor. i.e.

mains is applied, fuse is intact and the Emergency stop switch is not activated.

Fault LED

(marked UNNORMAL)

Amber LED that indicates that there is a fault or an incorrect control sequence. i.e. the chuck guard interlock has been activated or the speed control is activated without forward or reverse direction being selected. The Motor will not run if the fault LED is illuminated. If the safety interlock is activated, the safety interlock will remain in force until the interlock is reset and the start sequence re-initiated.

Fuse Cap

Access cap for the 20mm fuse cartridge (1 Amp 250V) Speed Control Knob Round raised ridge knob connected to the circuit that controls the spindle speed (100-1000 rpm or 100-2000 depending upon the gearbox selection).

Forward /Off/Reverse Switch

Three position switch that controls the direction of rotation of the spindle. Forward indicates that the spindle is turning clockwise (looking down from above, reverse, the spindle is turning anticlockwise. The centre OFF position inhibits the spindle from turning in either direction, under motor drive.

PARTS IDENTIFICATION AND DESCRIPTION

Quill hold pocket The size of the machine precludes any ʻfancyʼ locking mechanism for

the quill. There is a blind pocket on the spindle that accepts the tommy bar supplied in the tool kit, to enable the spindle to be held in position whilst the draw bar is loosened.

Draw bar cover A moulded plastic cover that clips into the top of the Motor Gearbox

assembly, to afford protection from the rotating top of the draw bar, when the quill is at the top of its travel.

Draw bar This is a metal rod, threaded M10 at one end and with an 8mm (unseen) squared shank and flange machined on the other. It is fitted through the

spindle mandrel to hold the fitted tool/tooling hard into the No2 MT taper of the spindle shaft.

GENERAL OPERATING INSTRUCTIONS

SETTING AND ADJUSTMENTS

GERERAL SAFETY POINTS

Warning Do not operate the mill in any function unless the head clamping lever is tightened.

Tool Changing

Note. The taper socket in the spindle mandrel does not have a ʻdrive flatʼ and all tooling, including the drill chuck is secured and driven by the taper lock and the draw bar.

Make sure the power is switched off or better still remove the power from the machine.

Locate and put to hand the 8mm A/F spanner and the tommy bar. Remove the Draw Bar Cover.

Hold the quill immoveable by inserting the tommy bar into the quill hold pocket and loosen the draw bar. Unscrew two or three turns and then strike sharply with a hammer (preferably a copper face, to prevent the head of the draw bar peining over) this will break the lock between the tool and the spindle tapers .

Unscrew the draw bar from the tool. Ensure the tool is supported, i.e. will not fall onto the workpiece/table et al. When it is free put the tool carefully aside, remove the draw bar, check the thread, check the taper and the thread of the new tool are clean and undamaged, introduce the new tool into the taper, re-insert the draw bar and screw into the top of the tool.

Screw in the draw bar finger tight. Hold the quill immoveable and tighten with the spanner. DO NOT OVERTIGHTEN. Replace the draw bar cover.

Remove all tooling and reconnect the machine. Ensure the tool path is clear, switch on, and check that the tool is correctly seated, is running true etc. If all is O.K, proceed.

Milling (all cases) Ensure the workpiece is securely clamped to the table.

Along the longitudinal Ensure that the quill is locked in position before Axis (X) milling is commenced. Ensure the traverse slide lock

is tightened.

Along the Traverse Axis (Y) Ensure that the quill is locked in position before milling is

commenced. Ensure the worktable lock is tightened.

Milling or Drilling Vertically Ensure the traverse slide and the worktable locks are (Z) tightened.

Milling Head adjustment

The Milling Head is mounted over a dovetail section. In order to maintain the ʻtightnessʼ of the fit; between the sloping surface of the component and its mating surface, on the left hand side, a gybe strip has been inserted. To adjust the gybe strip, use the supplied allen key and spanner, release the lock nuts and screw the gybe strip grubscrews clockwise to compensate for any slackness or anti-clockwise to loosen the movement. Check, using the rise and fall drive feed handles, that the head moves smoothly, If not, repeat the adjustments until the movement is smooth and tight over the whole of the travel.

Your Mill is a precision tool. In order to maintain this precision and prolong its useful life, it is advised that you follow the recommended daily and periodic maintenance tables printed below.

Daily and Periodic Maintenance

Daily

Carry out a visual inspection. Repair any damage immediately. Minor damage to the beds should be taken out with an oilstone. Move the worktable and the traverse feed back and forth by hand, check that the movement is smooth. Spread a light film of oil over the worktable and the traverse slide bed. Oil the end bearings of the drive shafts. Squirt oil onto the slide faces of mating components. Exercise the components to ensure the oil is spread over both visible and obscure surfaces.

Daily after-use

1. Clean all swarf and chips away from the machine bed, slide surfaces, and the tool post.

2. Exercise the slides and ensure no swarf etc., is lodged in the drive shaft tunnels. If you have been using a coolant make sure the machine is thoroughly dried off.

3. Check the tool, ensure it is usable the next time, if not re-sharpen or replace the tool tip.

4. Lightly oil spray all the machine beds and surfaces.

5. Clean and lightly oil any tools you may have been using (drill chucks, spanners, chuck keys etc), and put them away.

6. Switch off the power supply. Disconnect the plug.

7. Cover the machine over with a dust cloth.

Weekly

1. Move the traverse slide fully back to give access to the tunnel, blow out to make sure all swarf is cleared away and heavily spray oil the tunnel, exercise the slide to work the oil into the drive thread and to lubricate the dog.

2. Spray oil the slide and the worktable bed, exercise the worktable to spread the oil to all surfaces, both hidden and visible.

3. Spray oil the underside of the machine onto the drive screws, exercise to ensure the oil is coating all components.

4. Clean and spray oil the rise and fall drive screw, exercise to ensure all parts are coated.

5. Check the movement of the worktable, the traverse slide and the head, check they are smooth and ʻtightʼ, if necessary reset the gybe strips until the movements are smooth and tight.

6. Wipe the quill outer sleeve clean and lightly oil, exercise the quill to spread the oil in the sleeve bushes.

Monthly

a) Give the motor a good ʻblow throughʼ to remove any dust, dirt etc, b) Check all the interlocks function correctly.
