Spindle RPM
Trusted for decades, the a51nx reduces non-cut times with 1G-axis acceleration and a standard direct-drive B-axis. The machine’s robust casting design and roller-type linear guides support full, effective use of the work envelope. One-piece X- and Z-axis way covers and a dual-supported tool-change arm contribute to its industry-leading reliability.
The latest version of the a51nx’s Pro6 control includes several innovative productivity-enhancing features, including Process Tracer and Feed Optimizer, which are new components of Makino’s iKnowledge software. The new machine health monitoring system minimizes downtime and supports proactive machine maintenance, while coolant-tank stirring nozzles improve cyclonic filtration efficiency.
