NSK Improves Upon Successful Electer Design with New E-Max Grinder
Schaumburg, IL (March 7. 2002) - New from NSK America Inc.'s best-selling Electer line, the Electer E-Max Ultra-Precision, Multi-Purpose Micro Grinder is designed for superior performance and ease of operation.
Featuring a totally new design, the E-Max's control unit is both space-saving and functional. Control unit design enhancements include a digital speed display in x1000 rpm, soft touch buttons and computer control.
For easy handling and control, NSK has improved the design of its standard Electer to include an on/off switch directly on the motor.
For greater torque and control, the Electer E-Max uses a built-in microchip processor that allows for optimum motor output.
The Electer E-Max is available with the following motors: 1,000 -35,000 rpm, 1,000 - 29,000 rpm and 1,000 - 15,0000 rpm. Choose from 18 attachments; many new for the E-Max Series.
