Features:
Wheel Head: Ultra precision hardened nitralloy
spindle runs in anti friction bearings, grease packed for life. Its
production and testing under rigorous inspection ensures smooth,
trouble-free running.Hydraulic System:
Valve gear easily detachable and readily interchangeable. Minimum
amount of piping, connect pump to valve and cylinder block. The
System is lightly loaded with required pressure. Oil drains through a
fine filter before entering the Tank. Air in the system is expelled
during running of machine automatically.Wheel head Slide:
Wheel head column has precision ground guides on which the wheel head
slides on ball bearing rollers-grease packed. This feature ensures
rigidity and sensitivity essential for good finishes, control hand
wheel dial is graduated in 0.002 mm and has a floating zero for
convenience. Fine feed knob allows 0.002 mm increments in hand feed.
Increments of 0.00 I mm possible in P and AP versions.Table Traverse: Table traverse is both
hydraulic and manual. The table traverse on vee and flat guide"
way which are lubricated automatically. Stroke is set by adjustable
