Mill/Turn Center Produces Parts Faster than Twin Spindle, Single Turret Machines

In Booth S-338536, Absolute Machine Tools, Inc. (Lorain, OH) will demonstrate two LICO machines – a CNC screw machine and a mill/turn center. The mill/turn center on display is an LICO LNDD-series model: the LND-65D-S3 is an 11-axis mill/turn center that can often produce parts faster than conventional twin spindle, multi-turret machines with up to five tools in the cut simultaneously. This machine has a bar capacity of 65 mm (2.56 in), maximum turning length of 475 mm (18.7 in), and employs independent two-axis cross slides that can overlap each other and the turret. The turret works on either the main or the counter spindle, and can perform on-center work on both spindles simultaneously. An 8-position turret with optional live tooling and Y-axis is standard. The LNDD platform comes standard with an independent counter spindle, dual high pressure oil pumps, chip and part conveyors and tool holders for all positions.

The LNDD series is available in the following bar sizes: 42 mm, 51 mm, 65 mm, 80 mm, 100 mm, all built with a highly engineered frame and slides for dampening vibration and reducing the variables that can arise in size and finish from such vibration. The result is a very stable process at cycle times that are often two to three times faster than twin spindle, single turret machines.

LICO LNTS multi-slide screw machines can outperform even cam automatics. The LNT-42S-S4 model on display has a 42 mm spindle with four heavy-duty dovetail and gib-design cross slides that can overlap up to five tools in the cut at one time. This screw machine is ruggedly built and capable of using either form tools or standard carbide insert tools with each slide having a full two-axis servo-controlled travel. For medium to complex parts, it can match or beat the speed of cam-driven machines and offers the versatility, finish, and tolerances of CNC lathes.

A turret-mounted pickoff spindle is standard and the base machine model comes equipped with gang slide backworking, dual high pressure oil pumps, chip and part conveyors, and tool holders for all positions. A modular eight-position backworking turret is optional. The main turret uses VDI-30 live tooling and comes with four live tool holders. The LNTS platform is available in four bar capacity sizes: 36 mm, 42 mm, 51 mm, 65 mm, all with a maximum turning length of 170 mm. All LNTS models can be ordered with an optional Y-axis gang tooled cross slide for both static and live tools.
