Motor Spindle is a combined phrase of motor and spindle.
A motor is a device which transforms electric or air energy into mechanical energy for rotational power.
A spindle is a shaft for rotation. The power from connected motors can rotate spindles. We manufacture both motors and spindles. Since the motor and the spindle are used under connection, we use the phrase Motor Spindle.
The motor spindles manufactured by NAKANISHI are purposed for machining with attached tools.
Our motor spindles are used for drillng, milling by endmills, grinding by grindstones, and deburring by carbide cutters and/or brushes.
The motor spindles are not for hand work but mounted on machines, such as lathes, special purpose machines and robots.
NAKANISHI motor spindles are specialized high-speed rotation, high precision, and compact.
High-speed machining reduces machining time.
High-feed milling with small-diameter tools is possible while maintaining modest peripheral speed.
e.g. Groove milling (width 0.5 mm, depth 6 mm) at 150,000 min -1
reduces 90% of the processing time compared with the conventional motor spindle.

Spindle runout is within 1 μm.
e.g. φ50 μm ultra-small microlens array machining by ultra-precise machining devices
