Long-Bed Lathe
Long shafts and tubing pose unique challenges for turning centers, especially when deep-hole drilling and boring are involved. To meet those challenges, Haas Automation, Inc., introduced the new SL-40L Long-Bed lathe - a machine designed specifically to handle long parts.

The lathe is an extended version of the company’s SL-40 turning center that provides a maximum cutting length of 80" (nearly twice that of the standard SL-40) and a maximum cutting diameter of 25.5". In standard form, the machine features a 15" chuck and an A2-8 spindle nose that provides a bar capacity of 4.0". A 40-hp (peak) vector dual-drive system combines with a high-torque gear-box to yield 1,400 ft-lb of spindle torque for heavy cutting, and provides speeds to 2,400 rpm for finish work and high surface feedrates. On-the-fly wye-delta switching provides the high torque and wide constant-horsepower band necessary for constant surface speed cuts.

To accommodate large-diameter tubing, a Big Bore version of the SL-40L is also available. Other options for the SL-40L Long-Bed lathe include live tooling, full C axis, a fully programmable hydraulic tailstock, high-pressure coolant, a chip auger and a tool-presetter system.
