The EX series is a cam-actuated, indexing
tool post, designed with a roller gear cam mechanism
to incorporate extra-strong cam followers matched to
a globoidal cam. Cast iron housings and dual bearings
support the most extreme forces from any direction on
the output turret. Large diameter cam followers make
less revolutions and increase surface contact to inherently
extend life hours and torque capacity. Mechanical holding
force capacities of up to 1000-kgf are much greater
than traditional clamps and coupled hydraulic pumps.
As a result, this extremely high-torque mechanism is
capable of fast indexing speeds and consistent positioning
accuracy without the use of gear couplings.
internal components maintain long term positioning accuracy
within ±2 arc seconds. Simplistic designs without
external pumps make this unit user-friendly and easy
to service. The motor only runs when the unit is indexing,
therefore no thermal influence will affect your machining
process. Sankyo was the first to present indexing units
to the machine tool industry in 1990. With over 15,000
units sold, our legendary innovations and quality will
add value to your machinery for years to come.
