Power Chuck DURO-A
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
lubricant 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, 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-pres-
sure cleaner is not permitted.
2.6.4
Risk of Burns due to Hot Surfaces
The power chuck DURO-A may heat up during operation.
To prevent burns, do not touch the power chuck DURO-A 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 cent-
rifugal force which affects smooth running of the power chuck DURO-A. The
power chuck DURO-A has a balance quality of G 6.3 as per DIN ISO 21940.
Additional risks may occur due to insufficient rotational balance. 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.
Imbalanced workpieces endanger the personnel, the power chuck DURO-A
and the machine.
In order to compensate for unwanted imbalances and to prevent resulting
damage, the symmetrical mass distribution must be restored and the power
chuck DURO-A must be dynamically balanced with the workpiece.
