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.
