A long bed lathe - designed specifically to handle long parts, from oil field components to drive shafts to machinery rollers - comes equipped with a fully programmable hydraulic tailstock.
Long shafts and tubing pose unique challenges for turning centres, especially when deep-hole drilling and boring are involved. To meet those challenges Haas Automation introduces the new SL-40L Long-Bed lathe - a machine designed specifically to handle long parts, from oil field components to drive shafts to machinery rollers. The Haas SL-40L Long-Bed is an extended version of the company's shop-proven SL-40 turning centre that provides a maximum cutting length of 2032mm (nearly twice that of the standard SL-40) and a maximum cutting diameter of 647mm.

It also comes equipped with a fully programmable hydraulic tailstock.

In standard form, the machine features a 381mm chuck and an A2-8 spindle nose that provides a bar capacity of 101mm.

A 40HP (peak) vector dual-drive system combines with a high-torque gearbox to yield 1898Nm of spindle torque for heavy cutting, and provides speeds to 2,400 rev/min for finish work and high surface feedrates.

'On-the-fly' Y-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.

This option upgrades the machine to an A2-11 spindle nose and features a 171mm through-bore (chuck, draw tube and hydraulic coupling are not included).

To support extra-long parts through the bore, a rear chuck provision is available that allows an air chuck to be mounted to the rear of the spindle.

An optional steady rest platform is also available to provide increased support for turning and boring long shafts.

Hydraulic power for the steady rest is provided by the lathe, and the gripper (not supplied) is activated automatically via M code.

Other options for the SL-40L Long-Bed lathe include live tooling, full C-axis, high-pressure coolant, a chip auger and a tool-presetter system.

A number of control options are also available, including expanded program memory, Ethernet interface, user-definable macros and Haas' conversational Visual Quick Code programming system.

Like all Haas machines, the SL-40L features the powerful and user-friendly Haas control.

Designed and built in-house, it is optimized specifically for Haas machines.

The Haas CNC accepts ISO standard G code and is compatible with all major CAM systems.

MACH 2006 witnessed several brand new machines from Haas Automation, the largest CNC machine tool manufacturer in the world.

Haasl demonstrated machines and metal cutting technology for aerospace, automotive, medical, mould and die and general machining industries.

More than 25 CNC technology products were on show demonstrating vertical and horizontal machining and turning applications.
