Hyundai WIA announces an all new series of twin spindle CNC turning centers, the LM1600/1800TT. With upper and lower turrets and available Y- and C- axes, processing of complex parts in volume production runs, the new Series is really four machines in one, two lathes and two mills. These new turning centers feature high power built-in spindle motors and upper and lower turrets for high productivity.
Precise synchronized facing twin spindles reduce idle time and BMT-type turrets guarantee accuracy and power. The challenge today is for shops of all sizes to machine as many part features as possible in a single setup on a single machine. Central to accomplishing this is a machine that can do multiple operations (milling and turning) in a single set up, which the Hyundai WIA LM1600/1800TT accomplishes with ease. Benefits offered by the LM1600/1700 TT include compressing lead times from days to hours and reducing lot sizes with no cost penalty, lots as small as one piece can be done efficiently and cost-effectively. The Hyundai WIA LM1600/1800 TT also slashes non-value added time — fewer fixtures, tools and far less labor. Further, it also improves part accuracy by reducing tolerance stack ups between multiple fixturings.
Finally, the LM1600/1800TT reduces shop burden, fewer machine tools, reduced floor space and more cost effective use of utilities. You can also run untended; one operator can run several machines, or you can run an entire third shift untended — which increases cutting time without the attendant labor costs. The LM1600/1800TT Series features a 45 degree slant bed design, which was developed using finite element analysis (FEA) to ensure a stable platform for powerful, precise cutting capabilities. In order to eliminate thermal growth and increase accuracy, all axes are driven by high precision double-nut ballscrews. The pretensioned and double anchored design provides outstanding positioning and repeatability with virtually no thermal growth. Rapid high-speed axis movement is achieved by the use of linear motion guide ways in the Z-axis, complimented by box guide ways. This unique combination reduces non-cutting time and decreases machining time for greater productivity.
Related Glossary Terms
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
- turning
turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
