cut diameter in mm
Fig. 13: Selecting the speed
Example:
Determine the working speed for hardmetal burrs with
a cut diameter of 10 mm at a selected cutting speed
of v = 900 m/min!
Draw a vertical line from cut diameter 10 mm to the
intersection with the characteristic curve v = 900
m/min (indicated by a circle).
Starting from this intersection, a horizontal line to the
vertical axis on the speed scale indicates the speed
required is approx. 28,600 rpm.
Maintenance
Disconnect the machine from the

Checking the idling speed
Always check the idling speed
without any tools installed (grinding
tools, hardmetal burr, ...)!
The idling speed of the grinder must be checked
every 20 operating hours. Use a new tachometer to
do this. Always check the idling speed without any
grinding tools attached. In the case of an incorrect
idling speed, please send the grinder to our head
office or one of our authorised service centres.
When the operating pressure is 6 bar, the nominal
speed without a grinding tool must not be exceeded.

Other maintenance

Each time before starting work, subject the tool
(grinding tool, hardmetal burr, etc.) to a visual
inspection. Please replace worn grinding tools
immediately, otherwise there is a risk of injury.
Check spindles,
clamping devices regularly with
regard to wear and tolerances!
The speed and vibration must be checked after all
maintenance and repair work.
If defects are detected, return the unit to our head
office or one of our authorised service centres for
repair.
Protect the grinder, particularly the compressed air
connection and operating elements, from dust and
dirt.
