The iSpeed5 from NSK America Corp. Click image to enlargeThe iSpeed5 from NSK America Corp. is a fully tool-changeable electronic spindle.

Coming with either 60,000 or 80,000 RPM, the 350-watt, brushless DC electric system eliminates the need for operator intervention by using a special connection under the machine spindle that prevents coolant, chips, dust and other machining debris from contaminating the stop block. 

Its ultra-precision ceramic bearings handle high-speed performance and spindle accuracy of less than 1 micron (.00004-in.) T.I.R. for all micro milling, drilling and grinding applications.

The dry air purge system proves ideal for graphite machining as well as surfacing for mold finishing.  A wide variety of tapers are available.

The control unit features a motor protection system as well as an input/output interface to communicate with the CNC controller.

A hand-held device allows operation of the system from a distance and features all of the same buttons and functions as the main controller, including speed adjustment, reverse and reset. The stop block integrates with the controller to make automatic tool change possible. A variety of generic and custom stop blocks are available for all machine models.
