CNC TURNING CENTER
LNE42 SERIES
All operations that materials to designed parts can be completed on one LNE42.
To complete machining bar parts in one manufacturing operation, the C-axis, sub-spindle and live tools as well as back machining tools work coordinately to minimize cycle time while keeping measurements eithin designed tolerance.
Automations with Bar Feeder(1M~3.2M)
For non-stop operations, the LNE42 is capable to accommodate nearly every brand bar feeder. Selected bar feeder or designed secondary job magazine loader aides LNE42 in full automation and priced in favour of your budget.
Machining samples
LNE42 is designed to the metalworking sector. It has been adapted by various industries such as aviation, vehices, computers, plumbing fittings, optical instruments and others.
An appropriate production prposal with production rate defined by tool arrangement, cycle time andattachments can be offered before you purchasing.
8-station servo turret with rotary live tools
With bi-directional tool change feature, the servo-controlled 8-station turret rationally combined with a variety of rotary live tools give a beyond performance over classical turinings centers in both multiple machining and production efficiency. (i.e. rapid indexing time is 0.3sec./45° ; 8sec/180°)
Synchronous sub-spindle and back machining (Max. 4 tools)
The synchronous driven sub-spindle is a sophisticate design by LICO self. It is mounted in one station of turret to bring LNE42 the edge on pip-free parting off job and back machining. Due this feature, LNE42 shortens cycle times and increases machining flexibility.
The Siemens 800-series Controller
Siemens 840D control system, providing a user-friwndly console with a dialogue program, creates a simple operation environment. Particularly, the graphic trace of tooling path makes trainings and operations easier.
Background edit allows for reprogramming while machine running, this function minimizes waiting time and keeps efficency at a possible top rank.
The working space
The X-axis of quill-type travels at speed of 15 meters per minute within its full traverse of 160mm. The linear-way Z-axis travels at speed of 25 meyers per minute within its full traverse of 450mm. The compound design offers the machanic rigidity with rapid movement.
Parts catcher with conveyor
The finished workpiece can be discharged via a designed parts catcher on spindle or match with sub-spindle on rear side. In addition, for finished parts safe, a belt conveyor can be installed either on the front or the rear side of machine to deliver the parts to the preset tray.
The spindle package
Main spindle with a 7.5° increment, the 48-position dividing system is able to do more heavy-duty milling jobs. C-axis projects 0.001° increment enhances the capability of contour milling.

The chucking system
Either with standard F48 or optional Hainbuch 42 collet transfers LNE42 to bar-feeding operations up to diameter of 42mm (1 5/8 inch). An optional power chuck creats a chuck-machining up to diameter of 165 mm (6.5 inches) either with a manual feeding operation or the designed automatic loading system.
Servo controlled part-off slide
The programmable feed part-off alide is controlled by the servo system with prompt response to cut workpiece off precisely.
