The sealing air prevents foreign bodies such as chips and liquids (e.g. emul-
sions) from entering the HF spindle.
Ü
Check that air escapes at the front between the housing and the rotating
parts of the HF spindle.
5.5 Taper cleaning
Taper cleaning prevents chips and liquids from entering the shaft during a
tool change and causing contamination and damage to the inner taper and
the clamping system.
The taper cleaning is integrated in the pneumatics system for the tool change.
This means that no additional connections are required.
