Page 4: How To Install / Remove A Cutting Tool
Warning The Air Turbine Spindle rotates at very high speed. In case of using cutting tools with a big unbalance or tools with small diameter and long overhang, due to the centrifugal force, the cutting tool may break creating an extremely dangerous situation. - Page 5 UTILIZATION PROCEDURES [How to install a cutting tool] Insert the cutting tool in the collet – nut and tight it lightly with your hands. Reduce the overhang of the cutting tool as much as possible. (It greatly influences the T.I.R. and Rigidity.) Let project a little bit both side-lock screws of the X-Wrench, shift the handle on the “LOCK”...

Page 8: Concerning The Use Of Coolants P7
UTILIZATION PROCEDURES Concerning the use of coolants The Air Turbine Spindle, by using air purge for moving the turbine, is built to prevent coolants and oil mists from invading the internal parts of the holder. However, if the coolant is applied directly on the spindle body, it may invade its internal parts. -

Page 17: Installation Of The Manual Type
Installation of the manual type Warning Be sure to stop the rotation. When using the Air Turbine Spindle, it is not necessary to fix it using an anti-rotation bar, however, if the machine’s spindle is rotated by mistake, this may twist the air tube causing severe accidents. - Page 18 INSTALLATION Concerning the air supply Since the Air Turbine Spindle uses compressed air as driving source, if an air rich with moisture and foreign bodies is used, the bearings may rust or get stuck reducing the tool life. In order to use pure air, the following device is recommended.
