5.2 Adjusting the slide guide

guide rails, it may be necessary to adjust the slide guide.
In the case of both dovetail guide rails and roller bearing
rails, the slide guide is adjusted using the setscrews on
the side of the rail. The adjustment must be carried out
from the centre of the rail, in a homogeneous manner,
alternating from right to left.
For roller-mounted guide rails, the adjustment of the slide
guide (in the absence of a clearance) will be more refined
if we compensate for the weight of the elements of the
carriage by lifting them. The fastening screws of the rails
must not be loosened.
Attention: Only adjust the screws when the carriage is
positioned opposite the screw to be adjusted.
5.1 Lubrication
Lubricating norelem guide rails ensures protection against
corrosion, and reduces wear. Depending on stresses and
the environmental conditions, the first lubrication can be
effective for several years. However, be careful not to
leave a rail without corrosion protection if the lubrication
disappears.
It is important to avoid the ingress of cutting oil or spray
emulsion, as this can dilute the lubricant, and cause it
to spread. In addition, these emulsions tend to become
sticky when drying. Lubricants containing solid additives
must also be avoided.
Grey cast iron dovetail guide rails play a key role in sliding
guide systems, and may require periodic lubrication.
Lubrication grooves, which are fuelled by one or more
grease nipples, are provided for this purpose. The grease
nipples are fuelled by a special slideway lubricant - Mobil
Vactra No. 2 (original).
