ML3 Self-Cooled Linear Motors
Dowels on ML3S
Segmented secondary part
●
In certain cases, it is not possible to screw the secondary
part in direct contact with the machine as additional materi‐
als like distance plates, thermal grease and so on, are be‐
tween the secondary part and the machine. Then a sufficient
fastening of the screw connection must be ensured by the
machine manufacturer.
●
The effect of liquid screw lock is damaged by loosening or
re-tightening of screws (e.g. due to torque tests) and must
be renewed. Observe the instructions of the adhesive manu‐
facturer about correct screw lock.
When using dowels, ensure that they do not protrude more than
specified in the dimension sheets. This can lead to damaged sec‐
ondary parts.

WARNING
●
Secure against uncontrolled movement
●
Observe correct concatenation of secondary part seg‐
ments
●
Remove the transport or assembly protection only when
or after mounting into the machine
If several secondary part segments are used over the whole travel length,
keep the poles and the flush direction at concatenation according to the fol‐
lowing figure.
A correct assembly can be ensured as follows:
1.
Insert dowels for the first secondary part into the holes on the machine
bed.
When using dowels, ensure that they do not protrude more than
specified in the dimension sheets. This can lead to damaged sec‐
ondary parts.
2.
Place the secondary part in such a way that the dowels grab into the
secondary part and set down slowly.
3.
Fasten the secondary part with screws.
4.
As necessary, install additional secondary parts in the same order. The
secondary part that is installed last must have a minimum clearance of
10 cm to the primary part.
