In order to meet the special requirements for the thrum of wire core in the aerospace field a specialized wiregrinding machine was developed.This equipment used the ARM7 microprocessor LPC2214 as core controller and CPLD singlechip EMP570 as feedback circuit to control the servomotors with high precision.In order to get a smooth and flat section the wire core was rubbed out with precise length by the reciprocating moving sandpaper which was driven by the motors.This machine has already been utilized in real production and proved to be quite effective.
