Takumi's H12 Provides Rigidity for High-Speed Machining
The Takumi H12 CNC double-column machining center is designed for parts that require speed, accuracy and surface finish in the die/mold, aerospace and other high-speed applications.
The Takumi H12 CNC double-column machining center is designed for parts that require speed, accuracy and surface finish in the die/mold, aerospace and other high-speed applications. The ladder structure and double-column design provide rigidity and support to the head casting, while the one-piece base absorbs the inertia of high cutting feeds. The machine features a 15,000-rpm Big Plus CAT 40 inline direct-drive spindle. Thirty of the machine’s components are hand-scraped for accurate alignment.
The H12 is equipped with the FANUC 31-i-MB control, which features AI Contour Control (AICC) 2 with high-speed processing, machine condition selection and Nano smoothing. The control provides 600-block lookahead and a 1-GB data server with editing capabilities.
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.
Though it won’t replace high speed machining, Boeing sees “low speed machining” as a viable supplement to higher-rpm machines. Using new tools and techniques, a shop’s lower-rpm machining centers can realize much more of their potential productivity in milling aluminum aircraft parts.
Hand-scraping the mating surfaces of a CNC machine tool’s motion system offers myriad advantages.
