Pneumatic grinding spindles / robot tooling
-16-
Proceed as follows to determine what you need:
Starting from the blade diameter [mm]
draw a vertical line to the intersection with
the characteristic curve of the required
cutting speed [m/min].
Read the necessary working speed [rpm]
on the left-hand axis by drawing a
horizontal line to it from the intersection.
Fig. 6:
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.
Checking the idling speed
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.
Maintenance
Disconnect the machine from the
compressed air network before
starting any maintenance work!
Maintenance Unit
In order to ensure that the BIAX pneumatic
grinding spindles / robot tooling work properly, the
maintenance unit or the filter pressure reducer
should be checked at regular intervals.
Always check the idling speed
without
any
tools
installed
(grinding tools, hardmetal burr,
...)!
First of all, make sure the system is depressurised!
Remove all the condensation water collected and,
if necessary in case of oil-lubricated grinders, refill
BIAX special oil (for further information on BIAX
special oil, please refer to our catalogue).
This prevents damage to the ball bearings, motor
parts and rotor being caused by dirt or particles of
rust.
To do this,
drain off the condensation and
check the operating pressure (max. 6 bar)
at regular intervals.
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, threads and
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.
