User's manual
Extraction systems supplied by Planmeca serve exclusively to vacuum dry
milling dust. It is prohibited to vacuum cooling liquid residues with the
extraction systems supplied by Planmeca, and this leads to damage and
even destruction of the extraction system!
Extraction systems from Planmeca must be cleaned and maintained
regularly. Observe the separate operating and maintenance instructions
depending on the selected extraction system! Dispose of contaminants that
have collected in the filter and collection container professionally and
correctly, in accordance with the legal provisions and local regulations!
The workpiece holder must be cleaned of chips and dust before every
insertion of a blank, so that optimum clamping is possible. We recommend
using a suitable paintbrush for this. The screws and threads are to be kept
clean at all times.
The tool holders (in the tool changer) and the length measuring probe must
also be kept clean of dust and chips, in order to guarantee a faultless tool
change. The measuring surface of the probe must be kept clear of
contaminants at all times, because this is of elementary importance for the
precision of the milling unit. Clean the tool positions (tool holders) and length
measuring probe with a suitable paintbrush.
Defective or worn tool holders must be replaced. In this case contact the
local dealer.
Clean the guide rails of the lid at least once daily with a suitable paintbrush.
The guide rails and drive shafts are provided with long-term lubrication and
are maintenance free. If necessary they will be re-lubricated during
maintenance by qualified Planmeca personnel.
In order to guarantee a long service life of the main spindle drive, the
following points must be observed when handling:
•
Proceed with the necessary caution. Avoid the application of force, e.g.
impacts, striking, excessive pressure on the shaft or forceful clamping,
because the precision and service life of the spindle will be impaired.
•
The spindle nose and tools used must be clean. Dirt and the increased
centrifugal forces that arise from this result in a heavy load on the
spindle bearing, which significantly increases the spindle wear.
•
The hybrid ball bearing of the spindle is equipped with permanent grease
lubrication and is therefore maintenance-free. In order to achieve the
longest possible service life of the hybrid ball bearing, only well-balanced
tools should be used (reduced centrifugal forces).
•
In order to guarantee concentricity, the clamping device must not be
damaged. To check this, open the collet chuck, remove the tool and
check the collet chuck for damage, corrosion or soiling (deposits).
