Motor-Driven Guide Wheels: A motor drives the guide wheels to rotate at high speed, which in turn drives the circular steel cable (or saw blade) in a cyclical motion. Cutting is achieved through friction between the saw teeth or abrasive and the stone.

 

CNC System Control: Employs a microcomputer or PC-based CNC system (such as the Googol GTS series motion controller), supporting manual or PC programming to automatically complete cutting, edge grinding, grooving, and irregular shape processing.

 

Multi-Axis Linkage and Feed Mechanism: Features transverse, longitudinal, and lifting movements. Precise feeding is achieved through dual V-shaped guide rails, hydraulic cylinders, or linear motors, ensuring accurate cutting paths.

 

Tool Radius Compensation (C-Tool Compensation): For combined sawing, milling, and grinding operations, a C-tool compensation algorithm automatically adjusts the tool path to prevent overcutting and improve accuracy.

 

Auxiliary Positioning System: Some models are equipped with an infrared line marker that projects a visible laser line as a cutting reference line, achieving millimeter-level repeatability.
