Absolute Machine Tools (Lorain, OH) will display the Hi-Net DMC-1500HN Double Column Machining Center by Johnford at Westec. The center—designed for high speed net shape machining of complex 3D shapes—is ideal for aerospace manufacturers and mold/die shops wanting speed, rigidity, and precision in a competitively priced double column machining center. Features include a high quality integral spindle, heavy Meehanite castings that provide the strength and vibration dampening required for excellent surface finishes and exceptionally long cutting tool life. The columns and bridge are a one-piece casting for the best rigidity. A massive Z axis head and Y axis saddle feature square boxways and diagonally arranged ribs to minimize distortion caused by years of continuous service. The center features a moving table/fixed column design that provides maximum rigidity. A rugged 90 degree bridge with offset Y axis ways and a wide saddle keep the spindle center line very close to the bridge for further rigidity. The X axis table traverse is accomplished via heavy duty Schneeberger roller linear ways for accurate positioning of heavy work pieces. Large diameter, pretensioned ballscrews and powerful servo motors further ensure accurate positioning. The bridge mill delivers XYZ travels of 59” X 35” X 30” and rapid rates of 944”-944”-590” in X, Y, and Z. The rugged and rigid machine handles table loads up to 10,120 lb.
