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 sideway. 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

Tools must be always chucked in properly. This is

crucial for operational safety and working results. If a

workpiece is not clamped properly, it can be pulled out by

the feed 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
