Here’s an expert guide to adjusting your CNC metal circular sawing machine:

Spindle Rotation Number Settings: The spindle's rotation speed typically ranges between 80-150 rpm. The cutting speed of the circular saw blade, controlled by the servo motor and ball screw, is critical for precision cutting. Although manual advancement of the saw blade is possible, it's less common. The cutting process speed depends on the metal's hardness, usually set between 5-10mm/s.

Spindle Brake Adjustment: The spindle brake is designed to minimize the initial gap cut by the saw blade, enhancing the stability and reducing the load to about 0.4KG.

Oil Mist Sprayer Tuning: The machine uses a cutting fluid oil mist, sprayed at the saw tooth's front end. The typical consumption is 0.1-0.5cc/min. Adjustments can be made based on the material, ranging from 5-25 drops per minute.

Ammeter Monitoring: This feature checks the overload and blade replacement timing. Power requirements vary based on several factors, including the cut-off degree and spindle revolutions. Always confirm the maximum load power during sawing, with a typical setting ratio of 1.5KW-2KW.

It's crucial not to retract the saw blade during cutting to prevent equipment damage. After blade replacement, reset the machine to clear error messages.

By following these guidelines, enterprises can significantly enhance the efficiency and longevity of their CNC metal circular sawing machines.
