* Tolerance on Angle + 1°
* Surface Roughness : As cast : 3.0 To 6.0 Raµm
* Machining Allowance : 0.5 mm to 2 mm whereever machining fitment is expected.
* More closer dimensional tolerances also can be achieved, as per international standard, with additional operations.
* Configuration like, small hole, blind hold. slot, Groove, serration, Knurling, under-cuts can be achieved as cast, depending upon overall geometry, Complexity and size of the components.
