All CMZ turning centers come standard with the M415 chip-breaking function, a built-in solution designed to address one of the most common challenges in turning operations: long, continuous chips.
The M415 function works by intelligently varying the feed rate within a single cutting pass. This subtle, controlled modulation interrupts chip formation as the tool advances, causing chips to break into shorter, more manageable segments rather than forming long, tangled swarf. The result is cleaner chip evacuation, reduced risk of chip wrapping around the part or tool, and a more stable machining process overall.
This capability is especially valuable in roughing operations, where higher material removal rates and aggressive cutting parameters tend to generate problematic chip shapes. By breaking chips at the source, M415 helps protect tooling, improve process reliability, and minimize unplanned stops due to chip buildup—an important advantage for automated cells and lights-out production.
While highly effective, CMZ recommends using the M415 chip-breaking function specifically for roughing. Finishing operations typically prioritize surface quality and dimensional accuracy, where a constant feed rate is preferred.
In short, M415 is a smart, standard feature that reflects CMZ’s focus on real-world shop challenges—helping manufacturers run safer, cleaner, and more efficient turning operations without added complexity or optional upgrades.
