With the help of these levers spindle speeds are obtained in steps of 30 to 1235 RPM. Headstock gears are made out of special alloy steel and are hardened & profile ground. These gears are mounted on hobbed spline shafts and run in oil bath. Reversible type oil pump is fitted for lubrication. The main spindle is made of high tensile steel and is induction hardened & ground. This is rigidlyl mounted on 2 precision Taper Roller Bearings. Oil Glass Windows are provided to check oil level and output of the oil pump. Bed is interted 'V' type and deep in section which is made of close grained cast iron with diagonal webs to withstand torsional strains. The bed is strongly braced with cross ribs which provides a rigid frame work to the machine so that initial accuracy of the machine is maintained throughout its life. The lathe bed is Hardened & Ground with hardness of over 350 BHN Carriage is mounted on invert 'V' and flat guideways of the bed.

The bed is fine cut ground and thoroughly inspected. Head Strock : The square designed head stock with hardened spindle mounted on two precision Taper Roller bearings gives rigidity to the machine even in heavier cuts. Helical back gears can also be fitted for smooth rotation in lieu of Spur Back Gears. Saddle : The specially designed Long & Heavy saddle mounted on invert 'V' and flat ways of the Bed, which carries the long cross slide and compound rest with heavy square tool post. The operating screws are fitted with micrometer dials. A dial indicator is provided to facilitate easy engagement of leadscrew for thread cutting. Apron : It is four walled designed with independent drive motion for feeds and screw cutting with interlocking arrangements. All best quality gears, bearings and worm with GM bushing are lubricated from the oil sump provided. Tail Stock : It is mounted on inner V and flat ways of the bed with precision ground spindle with internal grinding.
