Tools chucking (pict. 3, 4, 6-8)

Because of joint shape there can be used only tools, chucking devices and tool brackets with Morse taper MK3 and inner thread M12 inside the spindle. Reducers cannot be used.

Tools chucking in the spindle and its removing

Chucking:

Turn off the machine and plug the power cord out! Remove the spindle guard (15). Clean up the conical shank (18) and spindle (4) and remove grease. To avoid accidents use a piece of cloth to hold the mill. To fix the spindle, insert a fastening pin (17) into the spindle bush sideway. Tighten up the pulling rod (19) with a flat wrench (SW10). The pulling

rod must be screwed in about 8 threads (clockwise) into the taper stud. Important: secure the tool and chuck always with the pulling rod to avoid self releasing of the tool. Remove the fastening pin (17) again and put the spindle guard (15) back again.

Removing:

Turn off the machine and plug the power cord out! Remove the spindle guard (15).

To fix the spindle, insert a fastening pin (17) into the spindle bush sidewall. Loose the pulling rod anticlockwise using a flat wrench (SW10). Loose the conical shank (18) by tapping the pulling rod (19) carefully with a rubber hammer and take it out from a spindle bush. To avoid accidents use a cloth to hold the mill. Put the spindle guard (15) back again.

Chuck manipulation

You can fasten into the chuck (9) cylindrical tools only with maximum shank diameter as stated. Use only perfect and sharp tool. Do not use tools with damaged shank or otherwise deformed. Use only accessories and attachments approved by manufacturer. Insert the tool shank into the chuck (9) whole the way in and tighten it up with a wrench, which is part of the delivery. Remove the chuck wrench again. Make sure the chucked tools are tightened properly.

Do not leave the chuck wrench in. There is great risk of injury by flying wrench.

Workpieces clamping

A Tools must be always chucked in properly. This is all for operational safety and working results. If a piece is not clamped properly, it can be pulled out by the used force of the mill and fling away.

This can be achieved by using machine vice (not part of the delivery). Thanks to fastening screws and adapters, the machine vice can be aligned precisely parallel to a slide lead.

To clamp a workpiece to the machine table, suitable clamping clips can be also used (not part of the delivery). To achieve firm holding of a workpiece, the clamping clips must be of right size.

Feed (pict. 7, 8)

All feeding movements must be carried out manually.

Normal and fine feed of the milling head (pict. 1/2/9)

Normal feed of the milling head

Pull the feed turning cross (14) out of the machine. Tool can be now brought to a workpiece by the turning cross quickly. Normal feed is used for drilled holes. Thanks to a depth stop (12) the drilling resp. milling depth can be regulated in z direction. To do so, loose up the arresting handle (20) on a depth stop (12). Put a depth stop into the position required and tighten up the adjusting handle (20) again. You can read out the feed position on a scale (21).

Fine feed of the milling head

Move the turning cross (14) towards the milling head (1) so the teeth of the tooth clutch (27) interlock. You can place the mill accurately now by using the control wheel for fine feed (7). One division on the scale corresponds with 0,02mm on the table track. If the desirable milling depth is set, the milling head (1) must be fixed firmly by clutching lever (28).

Cross-table feed (pict. 8)

Cross-table (2) can be moved manually in two perpendicular axes (X,Y) . The milling feed is executed by pressing the

handles (10,11). A zero position of the slide track is set by using a dimension on the handles scale. One division on the scale corresponds with 0,02mm on the table track. If the axes of the slide track (X,Y) are not in use, it is recommended to clip them with clutching lever (22).

Turning the milling head (pict. 1, 2, 11-13)

To mill beveled edges or V-grooves, the milling head can be turned to the left or right about 45^ . Warning: before you start adjusting, make sure that the machine is fixed to the table properly!

Turn the machine off. Hold the milling head (1) by hand to prevent it from tilting. Loose the fastening nut (13) with flat wrench (SW36). Unblock the neutral fixing device (23) by pulling it out. Set the desirable angle on the angle scale (24). Tighten up the fastening nut (13) again.

Lead calibration for litre cuts (pict. 14)

Distance between slide surfaces of cross and longitudinal slides and milling head can change when using extensively. To ensure perfect function and movement, the lead for litre cuts should be calibrated circa once a year. Loose up a jam-nuts (25). Adjust the calibration bolts (26) so there is an even pressure made on the lead for litre cuts on each calibration bolt. Hold the calibration bolt (26) with alien wrench (3mm) in position and tighten up the jam-nut back again. Tip: Tighten up the calibration bolts evenly, start always from outside on both sides, to achieve unified adjustment.

Processing

Drilling and deep milling

Insert a chuck and a tool as described and secure it with a pulling rod. Tighten up the chuck with chuck key. Set right revolutions (see paragraph "Revolutions setting"). Fix a workpiece firmly using machine vice or by using clamping clips. Move the cross-table (2) into desirable position (direction X a Y). Adjust a depth stop (see "Normal feed of the milling head") and make sure that a workpiece will not come into contact with a tool. Remove objects you are not using away from a work place. Turn the machine on and set right spindle revolutions by revolution selection switch (6). Drill or mill now. Warning: when drilling large holes, drill ahead with small drill first. Take the drill out of a workpiece regularly to get the chips out of the hole. You will get a drilling or milling depth by adjusting a depth stop (12). After you are done with your work put the milling head back to the upper position and turn the machine off. Clean up the machine and the chucking device and grease them up possibly.

Counter boring and centralizing drilling

Please take into account that counter boring is done with low cutting speed and small feed, while centralizing drilling with high cutting speed and small feed.

Face milling

Fix a chuck and a tool and secure it by pulling rod (19). Tighten up a chuck with a chuck key. Set the right revolution range. Warning: Do not change the revolution ranges (1 and 2) while the spindle is spinning! Fix a workpiece firmly using machine vice or by using clamping clips. Move the cross-table (2) into desirable position (direction X and Y). Adjust a depth stop (see "Normal feed of the milling head") and make sure that a workpiece will not come into contact with a tool. Remove objects you are not using away from a work place. Turn the machine on and set right spindle revolutions by revolution selection switch (6). Mill now. Adjust the cross-table by using manual handles in

a direction X and Y. After you are done with your work put the milling head back to the upper position and turn the machine off. Clean up the machine and the chucking device and grease them up possibly.

After using the machine, working table must be cleaned and greased again.
