Operation

Chapter One Overview

With 480×240 lattice TFT color graphic LCD, GSK 928TE

Ⅱ

CNC system takes as key control the

high-speed CPU and the complex programmable logic device of super-large-scale integrated

circuits. ISO CNC code is used to write part programs. The system is characterized by

-level

precision control, a full screen editing, Chinese operation interface, real time demonstration of the

machining process, and high cost-performance ratio. By means of programming, the system can be

used to control stepper motors, so as to machine outer cylinders, end faces, grooves, tapers,

circular arcs, and threads.
