2.6 Emissions
The level of noise emitted by the lathe is less than 78 dB(A).
INFORMATION
This numeric value had been measured on a new machine under conventional operating condi-
tions. Depending on the age or wear of the machine, the noise behavior of the machine might
change.
Furthermore, the extent of the noise emission is also depending on manufacturing
influence factors, such as speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is an emission level and not necessarily a safe
working level.
Unless the degree of noise emission and the degree of noise disturbance are depending on
one another it is not possible to use it in order to reliably determine if it is necessary to take fur-
ther preventive measures or not.

The following factors influence the actual degree of the noise disturbance of the
operator:
Characteristics of the working chamber, e.g. size or damping behavior,
Other noise sources, e.g. the number of machines,
Other processes proceeding nearby and the period during which the operator is exposed to
the noise.
Furthermore, the admissible pollution level may be different from one country to another due to
the national regulations.
This information regarding the noise emission should allow the operator of the machine to per-
form a better evaluation of the endangerments and risks.
CAUTION!
The machine operator has to wear an appropriate ear protection depending on the
overall stress caused by noise and on the basic limit values.
We generally recommend using a sound and ear protection.
