The machine bed is of box structure design with ribs providing high rigidity andstability. Main Table Slide moves on turcite coated autolubricated V and Flat guide ways which is given with absolute no stick & slip. It is driven by AC Servo Motor with pre loaded ball screw and rotary encoder. High precision glass scale can also be provided optionally.


Slide arrangement is particular designed for higher production and accuracies. The slide is running on rigid pre-loaded high precision hardened and ground guideways with autolubrication. This guarantees high repetitive accuracies and absolute stick-slip free of the slide.


It has a rigid Universal Work Head. It has cartridge type spindle. Work head spindle runs with P-4 Class antifriction precision angular contact bearings. Work head Speed has variable AC Servo drive.


It has a rigid Universal Wheel Head design. It has cartridge type spindle. Wheel head spindle runs with high pre-loaded P-4 Class anlifriction precision angular contact bearings. Wheel head spindle pully with poly V-belttype.


The Tail Stock spindle travels in perfectly honed bore. It is protected from dust. Tail Stock Spindle is spring loaded MT-3 Spindle made with high Carbon alloy steel.
