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.
INFEED SLIDE (WHEEL HEAD SLIDE) :
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.
WORK HEAD :
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.
WHEEL HEAD :
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.
TAIL STOCK :
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.
