� arm and column rigidly built with reinforcement ribs to reduce distortion, to give high capacity and lasting
accuracy.
Gearbox:
� completely oil bath gear box with 12 spindle speed steps with near geometric progression for the optimum
use of machine.
Gears:
� all gears gearbox are made up of nicr steel with hardness of
50-55 hrc with thickness of 15 mm.
Shafts of gears:
� all shafts made of nicr alloy steel with hardness 55 hrc.
Â�¢ all four splines and six splines of shafts are ground on
spilne grinding machine.
Spindle:
� spildle & spindle ram(quill) are made up of nicr steel
with final hardness of 55 hrc
� spindle is fitted with precision angular contact bearings not the taper roller bearings.
Â�¢ bearing sizes are internal ground.
Â�¢ pinion supported through bearings.
Ram liner bush:
� head stock is provided with high grade cast iron liner bush like in automobile engines for easy
sliding movement of ram and very long life. Also it ensures interchangeability when replacing after wear
out.
Auto feed system:
� 6 auto feed near geometric progression for all processes to be done like drilling, reaming, boring, etc.
Â�¢ overload safety clutch system for tool protection and machine protection.
Â�¢ spindle auto-stop with travel adjustment.
Spring:
� heavy duty helical spring has replaced old conventional type coil spring. This ensures far more life than
conventional springs.
Â�¢ limit safety devices are used to assure security while arm up-down, arm lock, spindle depth adjustment
