Speed : 1,000~50,000 min-1

Low Noise, Low Vibration

Speed is steplessly variable from 1,000~50,000
min-1. Smooth and powerful torque is delivered
at both high and low speeds. The extremely high
maximum speed of 50,000 min-1 allows high
precision micro-machining.

The brushless motor and incorporated cooling
fan have reduced the vibration and noise levels,
resulting in a quieter, more comfortable work
environment.
Dramatically compared with conventional grinders.

The electronic circuits are designed using NAKANISHI's proprietary
technology to meet eco-friendly expectations by minimizing power
consumption. Since power demands are minimal, no significant
heat is generated and no cooling fan is required.

NAKANISHI has given considerable thought to 'behind the
scenes' performance. The Espert 500 system complies with the
world's most rigorous EMC* standards. In electromagnetic
terms, it has been designed to be very safe so as to curb the
generation of electromagnetic interference (noise), which may
cause failure or malfunctions in other equipment. The Espert 500
system will not be affected by external electromagnetic
interference. The Espert 500 system also complies with the strict
European safety standard EN61010-1. Operator safety is always
NAKANISHI's highest priority.

The operation of all Espert 500 functions is controlled by a high
performance microcomputer (CPU) that is programmed with
NAKANISHI's proprietary technology. NAKANISHI's CPU has direct
control of the brushless micro-grinder allowing smooth and highly
precise cutting and polishing of a wide variety of materials. Bur
"chatter" has been eliminated. The system automatically senses which
micromotor is attached (ENK-500C or ENK-500T) and self adjusts to
provide optimum micro-grinder performance.

NAKANISHI Smart Switch
The switch provides a click sensation and a
confirmation tone is produced by the control unit
when the switch is operated. The motor type is
distinguishable by the switch color.

Other Features

The control unit is equipped with an auto cruise function that
operates the micro-grinder at a preset speed without the need to use
the foot pedal. This function eliminates foot fatigue during prolonged
operation.

Memory Speed Function FiXpeed ®
An exclusive new feature of the Espert 500 system, the FiXpeed
system allows the user to independently preset the speed of motor A
and motor B. For example motor A can be set to maintain the speed
set by the FiXpeed® system while motor B has variable control using
a foot pedal. This function allows for unprecedented flexibility.
