Vertical Lathes

Knuth Machine Tools USA has introduced the VDM series of vertical lathes in seven sizes from 31.5- to 102-in. swing. All machines are constructed with finegrain castings, a massive headstock, heavy machine bed, and wide box ways.

The machines are set up for OD/ID turning and feature a vertical ram with 5-station toolholder and horizontal side ram with 4-position toolholder.

The spindle runs in a high-precision, two-row roller bearing and is adjustable. Its reduction gear drive ensures high torque. Spindle motors are available up to 50 HP on the VDM 2600 machine. Machining heights up to 59 in. are standard, but options are available for extended columns for more height capacity. Maximum part weight capacity is more than 22,000 lbs.

This series includes models that feature an inverter-controlled turntable providing infinitely variable speeds in four gear ranges from 1.2 to 315 RPM. The machines also have a new control panel with a 3-axis digital readout and a spindle speed display.

Full enclosures, turntable enclosures, and chip conveyors are options.
