Introduction
Congratulations on the purchase of our kit for a
Compact-Line CNC portal milling machine. We re-
commend reading through these instructions com-
pletely before assembly and then assembling the kit
step by step as described.
Fig. 1: Completed Compact-Line
Note:
All directions (left, right, front, back, up and
down) in this manual are based on the view as
shown in the gure above.
Required tools
The following tools and aids must or should be avai-
lable during assembly:
• Common hand tools, such as Allen keys,
screwdrivers, plastic hammer, etc.
• A work surface that is as at as possible and
the same size as the base frame
• Flat or try square, at least 300 mm long in
tolerance class 1 or better
• Dial indicator with stand / holder
• Torque wrench from 6 Nm to at least 25 Nm1)
1) To avoid distortion caused by unevenly tightened
screws, the use of a torque wrench for load-bearing
screws M5 to M8 is recommended. Adhering to the
prescribed screw tightening torque also prevents un-
intentional loosening during later operation of the
machine.
Optional accessories
The fully assembled machine can be further supple-
mented and adapted to your requirements with op-
tional accessories. In the Sorotec shop you will nd,
among other things:
• milling spindles
• base
• enclosure
• vacuum table
• control electronics
• control software
• minimum quantity lubrication
Caution!
Only carry out the work if you are familiar with the
necessary actions and suitable tools are available.
Sorotec GmbH assumes no liability for damage to
property or personal injury occurring during assem-
bly or operation of the CNC portal milling machine!
General information
Please assemble the kit as carefully and precisely
as possible - the accuracy of the nished machine
does not only depend on the quality of the delivered
components, but also to a high degree on the correct
assembly and exact alignment. Before assembly, all
components must be checked for burrs and rewor-
ked if necessary.

Dimensions
Screw sizes are always given in the form of "diameter x length". In the case of metric screws, the diameter is
given by an M. Wood, sheet metal or plastic screws are not specially marked in the dimensioning. The unit of
measurement mm is usually not specified.
Examples:
M4 x 40 - metric screw with M4 thread and 40 mm length
3 x 5 - wood screw 3 mm in diameter and 5 mm in length
Web: www.sorotec.de
Diameter
Measurements are always made with the vernier caliper and on the
outside of the thread. To prevent the cutting edges of the measuring
jaws from slipping into the thread grooves, the screw is placed
lengthways between the jaws.
Length
Everything that disappears in the material is part of the
length of a screw. This means that measurements are taken
- ideally with the depth gauge of the caliper - from the
underside of the screw head to the end of the screw. Any
parts without a thread are also part of the length.
Exception countersunk screw
Because the head of the countersunk screw disappears
into the material, the head height here is part of the
length. So the length is measured over everything. But
really: Only with the countersunk screw!

Preliminary work
Pre-assembly of the
ball screws, spindle nuts and
bearing units Caution!
The pre-assembled recirculating ball nuts must not
be unscrewed from the recirculating ball spindles!
The ball nuts and ball screws are delicate and must
be handled with care!
In order not to damage the roller bearings during as-
sembly in the oating or xed bearing units, only the
outer bearing rings may be pressed/hit. Use a suita-
ble drive sleeve (tube) and oil the outer bearing ring
before assembly!
Install grease nipples (all drives)
• Equip all recirculating ball nuts with 90° angled
grease nipples (see gure 2, red arrow). Do not
fully tighten grease nipples yet so that you can
align them later.
Mount xed bearing (all drives)
• Push the rst bushing onto the ball screw.
• Push the xed bearing unit onto the ball screw.
• Push the second bushing onto the ball screw.
• Screw the shaft nut onto the ball screw
Attention: The collar of the shaft nut in the
direction of the xed bearing block.
• To adjust the axial play, tighten the shaft nut
until the ball screw can only be turned with
di󰀩culty in the xed bearing unit. Then carefully
loosen the shaft nut a little (approx. 5 °) until the
ball screw can easily be turned again.
• Screw the stud bolts into the threaded holes in
the shaft nut and tighten.
Install oating bearing (only X/Y drive)
• Press the roller bearing into the housing of the
oating bearing unit.
• Y-drive only: Push the oating bearing unit
onto the ball screw and attach the retaining ring
to the end of the ball screw.
Note
Floating and xed bearings are easy to distingu-
ish: the xed bearings have four mounting holes,
the oating bearings only two.

• Screw the linear rail 15 to the prole with
cylinder head screws M5x20 C4 uand slot 10
T-nuts M5 J1 ; the reference edge of the linear
rail marked with an arrow must be in contact with
the milled stop edge of the prole over its entire
length (see Figure 4).
• Tighten the screws evenly starting in the
middle and working outwards. Tightening torque:
6 Nm
• Repeat the work steps with the second prole
and second linear rail.
Note
The sealing plugs for the holes in the guide rails
prevent the accumulation of dirt and chips, which
could otherwise damage the sealing lips of the
carriages.
• Insert the sealing plugs into the holes in the
guide rails. Make sure they sit ush.

Note
When installing a bracket 32 on a component
without fastening grooves, the centering tabs on
the bracket must rst be removed (red arrows in
Figure 5). This can be done by breaking o with
a screwdriver, ling or grinding.
Fig. 5: Centering tabs on mounting bracket
32
These brackets are not installed on narrow ma-
chines with the width „03“! Accordingly, the work
steps for bracket assembly are omitted.

• Slide two carriages 14 onto the linear rails on
each side; the following should be noted:
- Ground, blank surfaces on the long sides
of the carriage point upwards towards the
tabletop.
- Equip the carriage with straight grease
nipples so that they point outwards (red
arrows in Figure 6).
• Screw the end plates 28 / 29 to the proles
with 2 at-head screws M12x30 N1 each;
Slightly counter-tighten the screws.
Note
„At the back“ of the Compact-Line slot table is
where there are four threaded holes on the un-
derside for mounting the xed bearing of the X-
spindle.
• Screw the bracket 32 to the underside of the
table top with M8x16 screws S2 and washers
X; Slightly counter-tighten the screws.
• Screw the brackets 32 to both end plates 28
/ 29 with cylinder head screws M8x20 S3 and
ange nuts T; Slightly counter-tighten the
screws.
• Tighten the mounting screws in the following
order:
- pan head screws
(end plates on proles of the table top)
- cylinder screws (angles on table top)
- cylinder screws / ange nuts (angles on end
plates)

Slightly counter-tighten the screws.
• Slide the oating bearing unit 4l onto the free
end of the ball screw and screw it to the table top
with two cylinder screws M6x40 E3 ; Slightly
counter-tighten the screws.
• Install the snap ring on the end of the ball

switch.
• Equip the switch carrier X with two cylinder
screws M8x12 S1 and washers X, loosely
unscrew the hammer nuts J2 at the rear.
• Position switch carrier X 25 , threading
hammer nuts into the T-slot of the prole. Slightly
tighten the screws to turn the hammer nuts 90° in
the T-slot.
• Place the reference switch 24 with underlying
shim and screw it to the switch carrier 25 with
washers Uand cylinder head screws M3x16

Before aligning the X-axis, check that the following
screw connections are not yet tight, but only slightly
counter-tightened:
E1 Connections portal beam / portal cheeks
D1 Connections angles / portal cheeks
C5 Connections angles / portal beam
C2 Connections angles / prole
• If necessary, loosen screw connections and
tighten slightly.
• Move the portal several times from one end of
the base frame to the other end while gradually
tightening the screws. The order is the same as
for the loose check:
E1 Connections portal beam / portal cheeks
D1 Connections angles / portal cheeks
C5 Connections angles / portal beam
C2 Connections angles / prole
• Check whether the portal can be moved easily
over the entire travel path after tightening all
screws.
• Press the cover caps onto the angles. Fig. 12: Tighten the portal screw connection
