Safety
• Chuck Key Safety: A chuck key left in the
chuck can become a dangerous projectile
when the spindle is started. Always remove
the chuck key after using it. Develop a habit
of not taking your hand off of a chuck key
unless it is away from the machine.
• Disconnect Power: Disconnect the lathe
from power before installing and removing
the chuck or doing any maintenance or
adjustments. Accidental lathe startup can
cause severe injury or death.
• Secure Clamping: A thrown workpiece
may cause severe injury or even death.
When swapping the chuck jaw positions,
keep in mind that maximum gripping
force is attained at full jaw and jaw screw
engagement. If only one is partially engaged,
overall clamping force is reduced.
• Speed Rates: Operating the lathe where
maximum chuck speed is exceeded, or at too
high of a speed for an unbalanced workpiece,
can cause the workpiece to be thrown from
the chuck. Always use the appropriate feed
and speed rates. A thrown workpiece may
cause severe injury or even death.
• Large Chucks: Large chucks are very heavy
and difficult to grasp, which can lead to
crushed fingers or hands if mishandled.
Get assistance when installing or removing
large chucks to reduce this risk. Protect your
hands and the precision ground ways by
using a chuck cradle or piece of plywood over
the ways of the lathe when servicing chucks.
• Safe Clearances: Often chuck jaws will
protrude past the diameter of the chuck and
can contact a coolant nozzle, tooling, tool
post, or saddle. Before starting the spindle,
make sure the workpiece and chuck jaws
have adequate clearance by rotating then by
hand through its entire range of motion by
hand.
• Stopping Lathe By Hand: Stopping the
spindle by putting your hand on the
workpiece or chuck creates an extreme risk
of entanglement, impact, crushing, friction,
or cutting hazards. Never attempt to slow
or stop the lathe chuck by using your hand.
Allow the spindle to come to a stop on its
own or use the brake (if equipped).
• Long Stock Safety: Long stock can whip
violently if not properly supported, causing
serious impact injury and damage to the
lathe. Reduce this risk by supporting any
stock that extends from the chuck/headstock
more than three times its own diameter.
Always turn long stock at slow speeds.
