Built with rigid box ways, 10 station turret and 15HP main drive motor, the S280N will be demonstrating its ability to 'hard turn' an aerospace component to a 'super precision' finish.

* vertical turning lathe - Doosan are one of the world's major manufacturers of vertical turning lathes (VTLs) producing VTLs for many well known automotive and aerospace companies in particular.

The Doosan V740 is one of the most popular size models in the VTL range and was displayed in single spindle format.

The machine has a maximum turning diameter of 740mm, cutting length of 760mm, 50HP main drive with twin range ZF gear box and 12 station turret and can accept chucks up to 24' diameter.

* Multi-axis CNC turning - wo examples from Doosan's multi axis turning range were featured during MACH.

The six axis sub-spindle S310SMLY includes Y-axis turret arrangement together with C-axis control of main and secondary spindle.

Other features include 12 station VDI style driven tool turret, maximum turning diameter of 311mm and machining length of 750mm, 10in chuck with 65mm bar capacity.

The machine will be shown producing a replica 'U' drill from bar utilising all six axes of control.

* Twin turret, multi-axis turning - the Doosan Z290SMY is an eight axis, twin turret, twin spindle turning centre.

Both main and sub spindles are fully synchronised and can be fitted with a combination of chuck or collect chuck.

Twin 12 station turrets can accommodate up to six driven tools in any combination whilst main and sub spindles both have full C-axis capability.

Maximum turning diameter is 290mm and machining length is 580mm with bar capacity of either 66mm or 77mm diameter.

For the MACH presentation the machine was coupled with a magazine bar loader and shown machining from bar a replica collet chuck that can be taken away and used as a desk paperweight.

Long bed CNC lathe has programmable tailstock

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.

Compact CNC lathe has generous capacity

CNC lathe takes up only 2m x 1.5m of floor space, yet provides a generous 255mm turning diameter, 355mm turning length and a 415mm swing over the front apron.
Turning small parts on a large lathe usually is not the most efficient use of a company's assets, and actually may have an adverse effect on the bottom line. The SL-10 CNC lathe from Haas Automation provides an economical solution for small parts turning in a compact package that is loaded with full-size features. The SL-10 takes up only 2m x 1.5m of floor space, yet provides a generous 255mm turning diameter, 355mm turning length and a 415mm swing over the front apron.

This compact machine is a valuable addition to any shop needing a 'second-op' machine, or wanting to add a lathe where space is at a premium.

It is also the perfect lathe for start-up shops, or as a first step into CNC turning.

The SL-10 comes standard with a 160mm hydraulic chuck and a 10-position bolt-on tool turret.

A 5.6kW vector drive spindle provides speeds to 6,000 rev/min for high surface feedrates, and an A2-5 spindle nose accepts bar stock up to 45mm.

A host of high-productivity options, such as a tool presetter, parts catcher, automatic chip auger and tailstock, are available for the SL-10 to further boost productivity, and the Haas Servo Bar 300 intelligent bar feeder may be added for unattended operation.
