ABT
ABT-1000 AIR TURBINE
- Ideal for extremely high precision, small diameter machining applications.
- Air bearings use compressed air blown into a small gap between the spindle and the bearing surface. The spindle floats on an even cushion of compressed air. This non-contact type of bearing means the spindle has a very long service life because of low friction and wear; it also means that the spindle generates almost no heat or vibration.
- The spindle and bearing are finished with a very high-accuracy process to ensure extremely low vibration and very high rotating accuracy.
- The ABT Series are equipped with a Rotational Speed Detection Sensor. When in operation, a digital pulse signal representing the RPM can be output. The rotation speed and load condition can be monitored using a high performance, locally available speed meter.
