DURO-A RC
▪
The maximum permissible speed is only permitted at maximum
clamping force.
▪ The power chuck only reaches the maximum specified clamping force
total when the maximum actuation force is applied.
▪ The clamping force must be checked
regularly
.
▪ Operation is only permitted with an effective safety guard.
The maximum torque which can be transmitted by the power chuck to the
workpiece depends on the technical design of the top jaws.
2.6.2
Skin Irritation due to Operating Materials
The lubricant consists of substances which may lead to skin irritations in the
event of frequent skin contact.
In order to minimise the risk of skin irritations, wear long work clothing and
avoid contact with the lubricant. Also observe the safety data sheet of the lub-
ricant and wear safety goggles and protective gloves during maintenance
work when handling lubricants.
2.6.3
Eye Injuries due to Metal Chips
Dangerous metal chips may be produced during machining of metal. During
operation or when cleaning the power chuck DURO-A RC, sharp metal chips
may be stirred up and cause eye injuries and cuts.
To prevent eye injuries and cuts, wear personal protective equipment during
operation and cleaning work. Cleaning with compressed air or a high-pressure
cleaner is not permitted.
2.6.4
Risk of Burns due to Hot Surfaces
The power chuck DURO-A RC may heat up during operation.
To prevent burns, do not touch the power chuck DURO-A RC after machining
and allow to cool down before carrying out assembly and maintenance work.
2.6.5
Dangers due to Imbalanced Workpieces
With rotating spindles, clamping of imbalanced workpieces generates a centri-
fugal force which affects smooth running of the power chuck DURO-A RC.
The power chuck DURO-A RC has a balance quality of G 6.3 as per
DIN ISO 21940. Additional risks may occur due to insufficient rotational bal-
ance. This applies in particular in the case of
▪ high speeds;
▪ when clamping asymmetrical workpieces;
▪ when using different top jaws or
▪ for all asymmetries of the power chuck DURO-A RC.
