D470 - Check wipers of upper telescopic covers
Orientation
Depending on the material used and the machining process, the telescopic cover
must be cleaned and checked regularly. In particular, before any prolonged
shutdown of the machine (e.g., during weekends). Cover sheets (static) and
telescopic covers (dynamic) are attached to protect the drive area (ballscrews, drive
motors, etc.) from contamination. Since the telescopic covers and wipers are
constantly in motion and also exposed to heavy pollution by the machining, they
must be regularly cleaned and oiled.
Always use the proper tool to remove chips.
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.
