NSK Nakanishi spindle is installed on all NS CNC mills. It is a world famous brand of mini machine spindles. The spindle has a long service life and is very reliable.
The spindle has motor speed feedback, digital display controlling, and monitoring. The maximum motor speed of 60,000 RPM is realized by using a high-performance brushless motor and ceramic bearings.
An air-cooled motor uses a small volume of air (1.0 CFM) to minimize heat buildup and allow continuous operation. Air pressure required is 75 PSI.
