Sandvik Coromant Quick Change for CNC Lathes - Manual (Page 24)

There is a wide range of machine options which will affect which clamping
units are best. The type of components being produced obviously determines
the requirements. Careful consideration of both the machine and options will
ensure that the process can be made most optimal.
Machine options
Shank
VDI (DIN 69880)
VDI (DIN 69881)
Turret interface options
The two traditional types of turret – Shank and VDI were developed when
turning centers only carried out turning and center line drilling operations.
The development of the driven tool holders has reduced their suitability for
multi-functional turning centers but the VDI dovetail is still the most robust
for heavier applications on flat bed lathes.
Bolt on turrets are well suited for multi-functional turning centers due to the
big benefit of more room inside the turret for the driven tool holder bearings
providing the best stability and shortest gauge lengths.
