Double-Column Machining Center

Engineered for high speed net-shape machining of complex, 3D parts, the Hi-Net DMC-1500HN by Johnford is a double-column machining center designed for aerospace and die/mold manufacturers. According to manufacturer Absolute Machine Tools, the machine’s moving table, fixed-column design and one-piece column and bridge casting provide rigidity. The 90-degree bridge with offset Y-axis ways and a wide saddle keep the spindle centerline close to the bridge.

The 90-degree bridge with offset Y-axis ways and a wide saddle keep the spindle centerline close to the bridge.

The machine features Meehanite castings to dampen vibration, improve surface finish and prolong tool life. In addition, The Z-axis head and Y-axis saddle have square boxways and diagonally arranged ribs to minimize distortion. For accurate positioning of heavy workpieces, the machine is equipped with large-diameter, pretensioned ballscrews. It uses Schneeberger roller linear ways for X-axis table traverse. 

The machine can accommodate workpieces weighing as much as 10,120 lbs, and XYZ travels are 59" × 35" × 30". The rapid traverse rate is 944 ipm along the X and Y axes and 590 ipm along the Z axis. The machine comes standard with a 15,000-rpm, HSK-100A spindle. For medium roughing and finishing, it is available with a 24,000-rpm, HSK-63A spindle or an 18,000-rpm, HSK-63A spindle. Other standard features include a Fanuc 18iM-B control, a 24-tool ATC and a chip-removal system.
