2.1 Emissions
Measurement according to operating conditions
The noise development (emission) of the radial drilling machine is 73 dB(A) at a rotary speed of
1252 rpm, measured at a metre's distance from the gearbox at a height of 1.6m when the
machine is idling.
The noise development (emission) of the radial drilling machine is 70 dB(A) at a rotary speed of
74 rpm, measured at a metre's distance from the gearbox at a height of 1.6m when the
machine is idling.
If the radial drilling machine is installed in an area where various machines are in operation, the
noise exposure (immission) on the operator of the radial drilling machine at the working place
may exceed 80 dB(A).
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine.
Furthermore, the noise emission also depends on production engineering factors, e.g. speed,
material and clamping conditions.
INFORMATION
The specified numerical value represents the emission level and does not necessarily a safe
working level.
Though there is a dependency between the degree of the noise emission and the degree of the
noise disturbance it is not possible to use it reliably to determine if further precaution measures
are required or not.
The following factors influence the actual degree of the noise exposure of the operator:

Characteristics of the working area, e.g. size of damping behaviour
,
Minimum distance from the spindle nose to the surface of
the machine base [mm]
470
Environmental conditions temperature +5 to +40 °C
Environmental conditions of rel. humidity 30% to 95% at 40°C ; 90 % at 20°C
Environmental conditions storage and transport -25°C to +55 °C
