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
