The DMF 260 linear from DMG now offers a 3,150-ipm rapid traverse, 15. 7" longer Y path and 7.9" more space in the Z direction, compared to the smaller machine.
All of the moving-column machining centers in the series are suited for aerospace applications and machine construction as well as tool making and mold production. The series can be upgraded and converted to meet a variety of application requirements, from three-axis milling through to five-axis simultaneous machining. According to the company, the worktable enables not only clamping of long workpieces and multiple clamping of small workpieces, but also machining in the pendulum mode (in combination with the optional partition) as well as series production with two separate machining compartments.
The 10,000-rpm, high-performance spindle features 212.4 foot-pounds of torque and an SK50 or HSK A63 interface, respectively.
The machine features a thermo-symmetric moving column and a base made of vibration damping mineral casting material. The standard version of the follower-type tool magazine, which holds 30 tools, ensures fast in-process tool-change intervals resulting in short chip-to-chip times, the company says. As an option, tool capacity can be increased to 60 or 120.
The machine features rapid traverse speeds of no less than 3,150 ipm in all axes. According to the company, workpiece precision is ensured by the combination of backlash-free, direct-drive technology in the X axis and the direct-measuring systems. The standard spindle features a maximum rotational speed of 8,000 rpm. A high-performance spindle provides a 212.4 foot-pounds of torque at rotational speeds ranging to 10,000 rpm, and spindle options enable rotational speeds of 14,000 rpm or 18,000 rpm, respectively.
