Emission measurement
Measurement in operating conditions in accordance with DIN ISO 8525 with surface areas
Measurement methods in accordance with DIN 45635.
The generation of noise emitted by the MH35G is 74 dB(A) on no-load running at 80% of max.
spindle speed, measured at a distance of one meter from the machine and at a height of 1.6m.
The generation of noise emitted by the MH35V is 78 dB(A) on no-load running at 80% of max.
spindle speed, measured at a distance of one meter from the machine and at a height of 1.6m.
If the milling machine is installed in an area where various machines are in operation, the noise
exposure (immission) on the operator of the milling 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 or damping behaviour,

other noise sources, e.g. the number of machines,
