LX SERIES
LX ser ies is a new l ine/range of high ef f ic iency CNC lathes.
The LX20T takes an 8 inch chuck wi th a spindle speed of 4500 rpm with an inter ference free turning diameter of 235 mm and maximum turning length var ying between 370 mm and 1040 mm.
l Optimal power – torque combinat ionl Low power consumptionl Increase in product iv i ty
MacHINE STRUcTURE
The box s t ructure FG 300 grade grey cast i ron bed opt imized through computer analysis, to achieve extremely high vibrat ion dampening character is t ics. Al l major machine cast ing are s t ress re l ieved impar t ing long las t ing accuracies.
HIGH PREcISIoN SPINdLE
The spindle is f ine grinded in a temperature control led precis ion grinding room, to achieve accuracies less than a micron.
l High precis ion bal l bearing in f ront & rearl Angular contact bal l bearing in betweenl Ribs on the outer body sur face to avoid thermal deformation
HYdRaULIc TURRET
l High precis ion 8 s tat ion bidirect ional hydraul ic indexing turret .l The indexing t ime per s tat ion achieved in less than a second
LX Series
HIGH RESPoNSE FEEd MEcHaNISM
The X and Z axis t raverses employs low fr ic t ion and s t ick -s l ip f ree movement L inear Motion (LM) guide ways.
The axis motors, provides ample feed thrus t to the bal l screws resul t ing in high rapid t raverse rates.
High precis ion in posi t ioning and phenomenal par t to par t repeatabi l i ty
TaILSTock
l Manual tai ls tock wi th a hydraul ical ly actuated MT-4 ADD-ON l ive centre.
l Programmable qui l l wi th a maximum thrus t of 500 kgf for turning lengthy jobs.
coNTRoL TEcHNoLoGY
The LX ser ies is equipped with high technology controls f rom SINUMERIK 828 D.
l User f r iendly sof tware creates a conducive environment for the operator.
l Maximum workpiece accuracy & minimum machining t ime.
