ULTRA-PRECISION BRUSHLESS MICRO-GRINDER • Evolutionary New Design High-Performance Brushless Micro Grinder. 1 ESPERT E-max Ultra-Precision Micro-Grinder IMPULSE PRESTO II SHEENUS neo 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. SONIC CUTTER 2 Types of Motors Very high torque from compact motors. NAKANISHI Smart Switch Color • Compact Type (ENK-500C) • Torque Type (ENK-500T) Blue Gray The handpiece has a patented built-in-dust protection system to prevent the infiltration of dust and debris into the front bearings. This NAKANISHI patented design assures long-term durability. Optimal Control via Microcomputer Compliance with EMC and other Safety Standards All of the Espert 500 system attachments are available for use with this system. 9 different types of attachments and 1 speed reducer making an almost infinite number of applications possible. IMPULSE PRESTO II SHEENUS neo SONIC CUTTER 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. High Quality Metallic Silver Body E800Z NAKANISHI Smart Switch 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. Eco-Friendly Design Auto Cruise Function 10 Types of Attachments Available ROTUS ECOMO 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. Special Dust-Proof Mechanism The Espert 500 brushless motor takes motor technology to an even higher level. The new state of the art motor has dramatically increased efficiency and torque output. The microprocessor based control unit provides optimal control of the motors and allows for increased flexibility in this multi-function system. ROTUS ECOMO New Advanced Design Control Unit 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. • Self Check Function (Maintenance Mode) • Smooth Operation • Operation Check Sound • Highly Visible and easy to operate front panel • 2-Digit Digital Display • Error Code Display Function *1 NAKANSHI's internal endurance tests 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. Excellent Durability High performance brushless motor eliminates the need to change carbon brushes. NAKANISHI's internal load test has proven continuous use for more than 5,000 hours.*1 Wide Range of Collet Chucks Available Collet sizes range from a tiny 0.3 mm up, with a wide variety of sizes available. Tools can be changed without the use of any spanners. Micro Grinder & Handpiece Stand This specially designed micromotor stand allows easy pick-up and set-down of the micro-grinder. Strong, but soft to the touch, the micro-grinder stand contains convenient, integrated storage compartments for adjustment spanners and a spare chuck. Simplified Hand and Foot Pedal Control You no longer need to push a switch on the control unit to switch between hand and foot pedal control. If you want to operate the motor handpiece by hand simply push the NAKANISHI Smart Switch, if you want to use foot pedal control simply depress the foot pedal. High Precision NAKANISHI's ultra-precision technology ensures bur concentricity of 0.02 mm or less, which allows for very high precision finishing.
