Basic Features
Optimized Layout and Design, Twin Spindle Front Loading CNC Turning Center
1Increased rigidity by changing the bed structure
In order to prevent decreased rigidity caused by load imbalance from sagging of the turret, and reduced lifetime of the give, LF2600 II Series increased the rigidity and realized high-precision product machining by designing protruded spindle headstock and Z-axis tool post.
Reduced Protruded Length of Tool Post :
507 mm > 269 mm (238 mm shorter)
2High Precision Structure
Separated Bed Structure
The LF2600 II series is designed as a separated bed structure, minimizing thermal growth and vibration, ensuring stable cutting capability.
Z-axis Structure
Prevent sagging of the turret by reducing the protruded parts of the headstock by changing the structure of the Z-axis, and allow for high-precision machining of the product by increasing rigidity.
< Secure rigidity through shortest possible design of the outer guideway to the spindle >
Get Close to the Spindle of the Cascaded Z-axis and Expand Span > Increased Rigidity
3Roller LM Guide / Box Guide
The transfer axis of LF2600 II Series give options for roller LM guide and box guide to ensure optimum conditions according to machining characteristics. (Standard : Box Guideway)

Spindle
Heavy Duty Cutting & High Accuracy
1Spindle for Heavy Cutting
The spindle has the highest speed and torque in its class, which provides high performance during high speed/heavy duty cutting. Also the spindle is designed with [Ø110 (Ø4.3″)] size P4 angular contact ball bearings to minimize thermal displacement and increase accuracy.
C-Axis Control (‘M’ Type)
C-axis of LF2600M II can be controlled to 0.001° which makes it possible to process various shapes.

Automation System
Various Devices for User Convenience
1Gantry Loader Machining Process
The high speed gantry loaders and the work stocker allow the implementation of automation cells. This enables machining process flexibility and productivity enhancement.
2Gantry Loader System
Gantry loader transfers raw material from in-stocker to machine automatically, starting machining process. Gantry automation provides good equipment access during operation and easy work monitoring, program modification and maintenance. In addition, small installation area facilitates optimized factory layout.
