Accurate Machine Tools has been engaged in manufacturing of precision heavy duty lathe machines. 
 
Heavy Duty Lathe Machines: Bed is deep in section and made of graded 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 lathe so that the initial accuracy of the lathe is maintained throughout its life. This is also provided with gap bed. Head Strock is of cone pulley type and the spindle pulley with GM Bushing. The spindle is of EN-8 steel of high tensile strength, hardened and ground having threaded nose running in plain parallel lead bonze bearings.
 
Saddle: The saddle is mounted on invert V and flat ways of the bed and thus the carriage has a long bearing on te bed. This carries the cross slide and the compound rest with square tool post. The operating screws are fitted with micrometer dials. A dial indicator is provided to facilitate easy engagement of the leadscrew for thread cutting.
 
Apron: It is of double walled designed with independent drive motion for feeds and screw cutting with interlocking arrangements. All gears and bearings and the worm are lubricated from the oil sump provided.
 
Tail Stock: It is mounted on inner V and flat ways of the bed with the hardened and ground spindle made from EN-B steel with internal grinding for dead centres and other tools.
