Rigid construction

+++Geared Headstock

+++The Spindle & gears are made of CR-MO alloy steel which are carburizing & precisely ground, forced lubricating & oil bathed combined in headstock which can be prolonged servicing life


+++Rugged heavily construction

+++Rugged heavily ribbed cast iron bed constructed, with hardened and ground Turcite-coated bed and saddle guideways for high accuracy and durability.
