The LND-65D-S3 11-axis turn-mill machine has a bar capacity of up to 65 mm (2.56") and a turning length of up to 475 mm (18.7"). It features 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 simultane- ously. The machine is avail- able in bar sizes of 42, 51, 65, 80 or 100 mm. Its highly engineered frame and slides are said to damp vibration and reduce variability in size and finish caused by vibrations. The LNT-42S-S4 screw machine has a 42-mm spin- dle with four heavy-duty dovetail and gib-design cross slides that can overlap up to five tools in the cut at once. The machine is capable of using either form tools or standard carbide insert tools with each slide and has a full two-axis, servo-controlled travel. Standard features include a turret-mounted pickoff spindle, backworking gang slide, dual high-pressure oil pumps, chip and part conveyors, and toolholders for all positions. The main turret uses VDI-30 live tool- ing and comes with four live tool holders. The machine is available in bar capacity sizes of 36, 42, 51 or 65 mm and a turning length of up to 170 mm. | Absolute Machine Tools Inc. | South, Level 3, Booth 338536
