Thank you for purchasing the Ultra-Precision, High-Speed Brushless Motor Spindle " HES810 ". The Brushless Motor Spindle is designed for use on machining centers without rotating the machining center's main spindle, for small diameter drilling and milling. The E3000 CONTROLLER, Motor Cord and Air Line Kit are required to drive this Brushless Motor Spindle. - Page 3 DANGER Do not rotate the machining centers' main spindle while the Brushless Motor Spindle is installed. Rotating the machining centers' main spindle with the Brushless Motor Spindle installed can cause the Motor Cord to become tangled, pulling the CONTROLLER off its mounting and cause severe damage to the motor cable and its connections.
- Page 4 ⑭ Do not disassemble, modify or attempt to repair this Brushless Motor Spindle. Additional damage will occur to the internal components. Service must be performed by NSK NAKANISHI or an authorized service center. ⑮ When using this Brushless Motor Spindle for mass production, please consider the purchase of an additional Brushless Motor Spindle to be used as a back-up in case of emergency.

Page 11: Changing The Tool
CHANGING THE TOOL CAUTION Do not tighten the collet without inserting a tool or dummy bur, as this will damage the collet, spindle or collet nut, causing difficulty removing the collet. RECOMMENDATION Please set the cutting tools to minimize the overhang amount. 13mm is the maximum amount of overhang to maintain high accuracy and safety. -
Page 12: Replacing The Collet
REPLACING THE COLLET CAUTION When installing the collet into the collet nut, be sure to fully engage the latch inside the collet nut to the groove on the collets outer diameter area. In addition, remember that if the collet is attached without being engaged with the latch of the collet nut, the collet cannot be removed and this may cause damage to the collet or the spindle. -

If problems exist in either the Emergency Air Joint or the Emergency Connector, please send the unit to NAKANISHI for service. Do not manually disconnect the Emergency Air Joint. - Page 14 ① Insert and Clamp the Brushless Motor Spindle into the machining center's main spindle. ② Remove the Electrical Plug Cap from the Brushless Motor Spindle by turning it counterclockwise (Fig. 15).

- Page 15 ⑧ Secure the Emergency Connector to the machine, being sure to correctly, horizontally position the Emergency Connector and Air Line. * Route the Motor Cord and Air Hose and hold them securely with enough slack to allow for machines' axis travel (Do not pinch and severely bend the air hose) (SEE Fig. 18). If the positioning and fixation of the Motor Cord and Air Hose are loose, the Emergency Connector may not seperate correctly as intended.

Page 16: Connection To The Controller
① Connect the Motor Cord and Air Hose as shown in Fig. 20. ② Be sure to use the NAKANISHI Air Line Kit (AL - C1204). The CONTROLLER and the Brushless Motor Spindle must be supplied with clean, dry air, regulated to between 0.25 - 0.3MPa (36.2 - 43.5psi). - Page 17 ① ALIGNMENT INSTRUCTIONS : To find machining center's main spindle center in relation to the Brushless Motor Spindle, mount a tool in a high-precision endmill holder or collet.

* If there is difference in the measurement, adjust the Brushless Motor Spindle centerline. With the Brushless Motor Spindle installed in the machining center's main spindle, use a dial gauge on the test pin originally provided in the collet. Slightly loosen the 6 bolts that hold the taper housing together, then slightly and tap the spindle to reposition the X - Y concentricity. -
