- Clean telescopic covers and wipers
Orientation
Depending on the material used and the machining process, the telescopic covers
and wipers must be cleaned and checked regularly. In particular, for dry machining
and before any prolonged shutdown of the machine (e.g., during weekends).
Dirty telescopic covers and wipers affect the accuracy of the machine and its service
life.
Contamination of the telescopic covers and wipers results in increased friction
(stiffness) of the plates. This may damage the telescopic covers and wipers so that
contaminants can get into the area behind the telescopic cover. This in turn may
cause damage to other machine parts, requiring expensive repair. In the event of
damage, determine the cause of the damage and immediately notify the machine
manufacturer or its representative company.
After cleaning, the telescopic cover must be coated with low-viscosity
oil.
The oil must not resinify and sediments must not form when exposed
to other fluids or machining residues (e.g., metallic dust). Otherwise,
the service life of the wipers would be considerably impaired.
Requirement
Before starting the cleaning, move the tool slides to positions that are more
convenient for the cleaning process.
Power off the machine and secure it against power on.
Procedure
1. Clean telescopic plates. Remove chips with a suitable chip hook or hand-held
broom. Afterwards rub with a cloth.
2. Check telescopic and guide plates for damage. Look for deep scoring or
abrasion.
3. Oil the telescopic covers.
4. Switch the machine on and move the tool slides until an even film of oil is visible
over the whole traversing range of the telescopic cover. If relubrication is
required, first stop the travel movement and set feed rate override to “zero”
position.
