Okuma's Genos M660-V VMC Handles Large Workpieces in Small Footprint
Okuma’s Genos M660-V vertical machining center combines a large work table, a compact machine footprint and a CAT 40 Big-Plus spindle for machining large, complex parts. An optional CAT 50 Big-Plus spindle is also available for heavy cutting jobs. The larger table minimizes restrictions on workpiece size and tool length while leaving ample space to add rotary tables, the company says. The table measures 660 × 1,530 mm (60.24" × 25.98").
The machining center is built with Okuma’s Thermo-Friendly Concept technology, giving it the ability to withstand thermal deformation during the machining process. The technology is also said to eliminate the need for machine warmup. The rigid, double-column construction reduces vibration for less wear and tear on critical machine components as well as improved machining performance. The Genos M660-V is also one of the heaviest machines in its class, according to the company.
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
Accuracy is not just inherent to the machine—it also depends on how the machine is used. Try these techniques to let a new or existing CNC machining center achieve its potential precision.
Cryogenic machining achieves dramatic tool life gains not by flooding the cut, but by refrigerating the tool.
