When machining long workpieces, clamp the free end
of the workpiece securely with the tailstock or a steady
rest (if installed).

Before clamping a workpiece in the chuck, check using
a pressure gage that the correct hydraulic or air
pressure is supplied to the cylinder that actuates
chuck operation.

If a gap exists between the workpiece rear surface and
the chuck locator face or the jaw face on which the
workpiece is to be seated, the workpiece rotation
centerline is tilted in relation to the chuck rotation
centerline, or if the workpiece is cast or forged, carry
out test cutting at a low spindle speed to ensure safety.
[Cutting force exceeds workpiece clamping capacity of
chuck, causing workpiece ejection]

When a workpiece is eccentric, not round or the center
of gravity of the workpiece is not at the center of the
rotation, balance using a balancer with full
consideration given to machining conditions such as
the spindle speed.
