What applications benefit from the DNM 750L II’s extended travel?
The DNM 750L II is designed for large, elongated parts that require stable machining across long distances. It excels in aerospace, mold & die, large plate work, and general machining where extended travel and high rigidity are crucial. The oversized table and reinforced column structure allow for heavy fixtures and multi-part setups with consistent accuracy.
How does the DNM 750L II maintain precision over long cycles?
Thermal stability is achieved through features like an oil-jacket spindle chiller, ball nut cooling, and Meehanite cast iron construction. The roller linear guides and double Y-axis way support system help maintain alignment and absorb machining forces, ensuring precision even during long-run operations or heavy cuts.
What makes this spindle system different from others?
The DNM 750L II uses a direct-drive, cartridge-style spindle with 12,000 rpm capability and dual-contact Big Plus CAT 40 taper. This reduces vibration and thermal expansion while improving tool life and finish quality. The rigid tapping functionality and fast accel/decel times (2.2 sec to/from full speed) further enhance productivity for complex or multi-featured parts.
Can this machine be used for automated production?
Yes. The DNM 750L II is probe-ready and includes integrated Adaptive Feedrate Control and Tool Load Monitoring, making it well-suited for unattended or lights-out machining. The machine can detect tool wear, broken tools, and even air cuts, helping manufacturers reduce downtime and improve efficiency in high-volume or high-precision production settings.
How much floor space does the machine require?
The DNM 750L II requires a footprint of approximately 193" x 135" and stands 125" tall. Despite its long X-axis travel, the compact footprint and integrated chip management systems make it a practical solution for shops managing large workpieces without sacrificing valuable floor space.
