Knuth Machine Tools’ VDM 1250 vertical lathe features a 49" maximum turning diameter and a 30-hp motor with variable speeds in four gear ranges. The machine is equipped for OD/ID turning and features a vertical ram with a five-station toolholder and horizontal side ram with a four-position toolholder. The adjustable spindle runs in a two-row roller bearing. Its reduction gear drive ensures high-torque capabilities, the company says. Machining heights ranging to 59" are standard, and extended columns options are available. The lathe can accommodate parts weighing more than 22,000 lbs.
The seven-machine series ranges in size from 31.5" to 102" swing. All machines are designed with fine-grain castings, a headstock, a heavy machine bed and wide boxways. They also include inverter-controlled turntables to provide variable speeds in four gear ranges from 1.2 to 315 rpm. The control panel’s three-axis digital readout displays the spindle speed. Options include full enclosures, turntable enclosures and chip conveyors.
