The Z-factor
In this column we always showcase a technical high-
light from ZOLLER – today, the high precision spindle
»ace«.
Since its inception, the »ace« spindle has been mo-
dified several times, yet the basic principle remains
the same – and is as simple as it is brilliant: with its
quick change device for tool posts, it can be used
universally for steep tapers, hollow shank tapers,
Capto and Kennametal – and always with extreme
accuracy, with a concentricity of 2 µm.
In focus:
the »ace« high precision spindle
——
Tool post change via ball bushing: quick, absolutely
free from backlash and with a guaranteed change
precision of 0.001 mm.
——
Tool cap-head bolts for steep tapers (ANSI, CAT,
MAS-BT) as well as HSK, Capto, KM and VDI of vari-
ous sizes can be clamped, from 7 to 30 mm in dia-
meter and tension lifts of 122 mm axially and 11.5
mm radially.
——
A change of clamping element is not necessary.
