New Machining Center Built for Speed and Precision
Makino announces the F5 Pro6 vertical machining center designed to provide stiffness and rigidity for chatter-free cutting, agility for high-speed/hard-milling and accuracies for tight tolerance blends and matches typical of complex, 3D contoured geometry associated with die/mold and medical production.
The F5 has been built from the ground up for speed and precision. The design begins with a unique axis configuration, featuring no overhangs, and incorporates large castings that provide a robust cutting platform. It then integrates 8 mm fine pitch ball screws and 0.05 micron scale feedback as standard equipment providing superior precision. Temperature controlled, core-cooled ballscrews and support bearings ensure long-term thermal stability, the company says. Even the servo systems are tuned for peak performance. Together, these features reduce variability for hours of continuous, tight tolerance machining.
The F5 features X, Y and Z-axis travels of 35.4-, 19.7- and 17.7- inches respectively, a 39.4 by 19.7-inch table and a maximum workpiece size of 39.4 by 19.7 by 17.7-inch. It has a table load capacity of 2,204 pounds, and a 30-tool magazine provides capacity for a wide array of tooling. An optional 60-tool magazine is available to provide a larger tooling compliment, reducing tool setup and change-over times.
Here are techniques commonly used to combat chatter and guidelines to establish a foundation for optimizing the moldmaking process.
With moldmaking the focus is on injection molding or other mold types that use wire EDM or CNC machining centers to create the mold components. Your typical machining center weighs several tons and has a relatively small working envelope compared to a CNC router. The mill’s massive construction lends itself to machining rigid materials with very tight tolerances. While this type of CNC is suited for injection molding components, it isn’t always the ideal tool for the job when we broaden our scope of moldmaking and the current opportunities in the marketplace
In the last two years, there have been many exciting developments in high-speed machining relative to machining centers and controls, tooling and CAD/CAM systems.
