LX SERIES
LX series is a new line/range of high efficiency CNC lathes.
The LX20T takes an 8 inch chuck with a spindle speed of 4500 rpm with an inter ference free tur ning
diameter of 235 mm and maximum tur ning length var ying between 370 mm and 1040 mm.
Optimal power – torque combination
Low power consumption
l Increase in productivity

l
Machine Structure
The box structure FG 300 grade grey cast iron bed optimized through computer analysis, to achieve
extremely high vibration dampening characteristics. All major machine casting are stress relieved
impar ting long lasting accuracies.

High Precisi on S pindle
The spindle is fine grinded in a temperature controlled precision grinding
room, to achieve accuracies less than a micron.
High precision ball bearing in front & rear
l An gular contact ball bearing in between
l Ribs on the outer body sur face to avoid ther mal defor mation
l
HY DRAULIC TURRET
l
l
High precision 8 station bidirectional hydraulic indexing turret.
The indexing time per station achieved in less than a second
LX Series
HIGH RESPONSE FEED MECHANISM
The X and Z axis traverses employs low friction and
stick-slip free movement Linear Motion (LM) guide
ways.
The axis motors, provides ample feed thrust to the
ball s crews resulting in high rapid traverse rates.
High precision in positioning and phenomenal par t
to par t repeatability
Tailstock
Manual tailstock with a hydraulically actuated MT-4 ADD-ON live
centre.
l Programmable quill with a maximum thrust of 500 kgf for tur ning
lengthy jobs.
l
Control Technology
The LX series is equipped with high technology controls from
SINUMERIK 828 D.
l
l
User friendly software creates a conducive environment for the
operator.
Maximum workpiece accuracy & minimum machining time.
