Important Safety Precautions
Do not allow the rotation speed of the chuck to exceed the maximum allowable
speed limit. (Refer to pages 12-16)
For All Users
・If the rotation speed of the chuck exceeds
the rotation speed limit, this is very
dangerous as the chuck and work will fly
out.
The input force of the chuck (piston thrust, pulling force of the draw pipe)
must not exceed the allowable maximum input force.
(Refer to pages 12-16)
For All Users
・Input must match the specification of
the chuck.
・Adjust the hydraulic pressure to the
cylinder so that the input force, which
determines the gripping force of the
chuck, does not exceed.
・Excessive input force can lead to
breakage of the chuck, which is very
dangerous, as the chuck can work
can be damaged and fly out.
If you use the chuck with the inside diameter gripping, input force (hydraulic
pressure) must be 1/2 or less of the allowable maximum input.
(Refer to page 16)
For All Users
・The chuck may break and the chuck
or work could fly out.
Failure to follow the safety precautions below will result in
serious injury or death.
DANGER
・If it's used at the low setting pressure and
the gripping force isn't enough against the
cutting torque or centrifugal force can lead
to breakage of the chuck, which is very
dangerous, as the work can be fly out.
・If it's used at the excessive setting pressure
can lead to breakage of the chuck, which is
very dangerous, as the chuck or work can
be damaged and fly out.
・If the protrusion is
long, the tip of the
work can turn and
the work fly out.
In case that a combination of cylinder is changed by model change,
it is necessary to change setting pressure.
Failure to follow the safety precautions below will result in
serious injury or death.
DANGER
Keep the height of the jaw within the range specified in the gripping force limit table (Refer to page 15).
If you must use a jaw taller than a standard soft jaw, use less than the input (piston
thrust force, draw pipe drawing force) specified in the gripping force limit table.
For All Users
・Do not use a jaw of a height out of
the range of the gripping force limit
table or a jaw with mass moment out
of the range of the gripping force
limit table. The chuck will break and
the chuck and work will break and fly
out.
For All Users
When the protrusion of the work is long, support it with
the steady rest or center.
For All Users
Determine the gripping force required for processing by the machine tool manufacturer or user,
and check that the required gripping force is provided before processing.
(Refer to pages 12-16 and cylinder manual)
・Adjust the hydraulic pressure to the
cylinder to obtain the required gripping
force. If the gripping force is insufficient,
this is dangerous as the work will fly out.
