4.6.4 Automatic tool holder collet spindle cleaning
The tool-holder cone and its conical housing in the spindle shaft are cleaned with the aid of a jet of
compressed air during the tool change phase.
This procedure protects the coupling surfaces from the deposit of impurities.
The condition of the coupling surfaces and their degree of cleanliness should be checked
periodically, as described in section
7 “Programmed maintenance” .
1 Mains power supply
2 Pre-filter 5 µm
3 Oil separator filter 0.1 µm.
4 Pressurisation air inlet 4 bar - 58 PSI
5 Continuous flow of pressurisation air
6 Exposed area of the screw dowel with Ø hole for cone cleaning 6 bar - 87 PSI
THE PROPOSED CIRCUIT IS PURELY EXEMPLARY.
The jet of compressed air is active the entire time the collet remains open.
Create a hole in the expulsion actuator of the ES370 electrospindles to allow for
the passage of compressed air in order to clean the cone during the tool
changing phases.
