- Check wipers of Z axes on main and counter spindles
Orientation
Due to their open-access location, the main and counter spindle wipers may be
contaminated or impaired by chips particularly hard. Therefore, special attention
should be given to the condition of the wipers during maintenance activities.
Regularly checking the wipers prevents accelerated wear of the covers. This test is
a visual inspection. But if the wiper is destroyed and no longer snugly contacts the
contour of the guide, it must be replaced. It is essential to ensure absolute
cleanliness when removing and installing the wiper.
The wipers should contact the plates over the entire length or the entire travel of the
Z axis (see example). This ensures that no chips or dirt can settle in the space
behind the wipers.
Requirement
Move the tool carriers to a suitable position. For checking the outer wipers, it may be
necessary to remove parts of the machine enclosure. To move to the positions in
which the wipers can be checked, it may be necessary to switch the machine on/off
several times.
Procedure
1. Move the tool carrier to the position suitable for checking.
2.
Caution
Moving tool carriers.
Risk of bruising and lacerations.
Switch off the machine via the main switch or shut down with the
emergency stop.
Remove relevant machine enclosure.
