Methods Machine Tools Inc. (Sudbury, Mass.) is offering a new configuration of the RoboDrill T-21EL DDR 700 V-size vertical machining center. Available with either 10,000-rpm or 24,000-rpm spindles, it employs a direct-drive indexing system that is designed to achieve extremely high positioning and cutting speeds in the fourth axis, thus reducing part cycle times by eliminating the positioning delays of traditional rotary tables. The drill's gear-free, zero-backlash linear motors are capable of unclamping, rotating 180°, and reclamping in 0.4 seconds at a table-rotation speed of 150 rpm. The unit has a maximum torque of 192 ft/lb and a maximum loading capacity of 220 lb.
