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 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.
Old-world craftsmanship combines with precision machining on a vertical machining center and Swiss-type lathe to produce some of the only U.S.-made mechanical wristwatch movements.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
