Cartridges and
High Precision Subassemblies
As a basic unit, the ready-to-install spindle cartridge featuring hollowshaft drive and pick-up interface offers a complete technology for boring and drilling, milling and turning on vertical turning and boring mills,
gantry milling machines and bore & mill machines. High torque and
high speed provides efficient machining.

High precision subassemblies
in cartridges for vertical turning and boring
mills and gantry milling machines
HEADTec's high-speed quill units are available as ready-to-install
high precision subassembly for bore, drill & mill machines and
machining centers. Usually fitted to the head slide, they may also
be integrated in the machine's RAM as a complete subassembly,
including the main drive and the feed drive.

Hybrid spindle bearing
Mechanic-hydraulic, self-locking tool chucking system
Tools with cartridge cooling to shield from tool heat
Quill cooling to keep clearance between quill and milling spindle constant, and a sophisticated
technology to establish the high-precision tribological pairing between quill unit and milling
spindle
This grants a high cutting performance over the whole quill unit travel.
High machining quality is a characteristic feature.
