Block head 4B universal air bearing spindle
* Block head Universal air bearing spindle.
The BLOCK-HEAD family of air bearing spindles combine rotational accuracy with extremely high stiffness comparable with that of heavy-duty ball bearing headstocks. These spindles are suitable for accurate support of overhung loads, and their unique combination of accuracy and stiffness makes possible direct machining to optical tolerances and finishes.
BLOCK-HEAD spindles have been used successfully from less than 50 psi up to 200 psi, and have shown no signs of instability. They will operate equally well in any position, over a wide speed range, and in a variety of environmental conditions. Add-ons such as motors, chucks, mounting plates, and custom tooling benefit from the correct nature of the BLOCK-HEAD design.
