Taper serrations in components like Pitman-Arm are produced by broaching
followed by taper serration drifting using precision taper serration
drifts.
Taper serrations in components can be inspected by taper serration plug
gauges manufactured by MATS.
Components which require good dimensional control on spline profile after
heat treatment must use quenching plugs which are fitted in internal
splines.
Taper serrations drifts are supplied from HCHCr(D2) and Taper Serration
plug gauge & quenching plugs are supplied
from OHNS.
