WHEELS
TECHNICAL INFORMATION
TROUBLESHOOTING CUTTING OFF WHEELS
Wheel does not cut
Cause
Solution
in case of blue cutting: wheel too hard or too thick use softer or Flexovit Thin Cut wheels,
check peripheral speed
Cause
Solution
peripheral speed too low
increase rpm up to max. (80m/s)
Excessive wear
Cause
Solution
in case of white cutting edge: wheel too soft
use harder wheel
Cause
Solution
operating speed too low
increase rpm up to max (80m/s)
Cause
Solution
decrease of rpm during cutting
use machine with more power, reduce pressure on the machine
Crumbled wheel edge
Cause
Solution
cutting-off wheel used for grinding operations
use a grinding wheel for grinding operations
Cause
Solution
workpiece is moving
clamp the workpiece properly
Cause
Solution
too much side-pressure
add only the radial pressure to the wheel
Arborhole or centre break out
Cause
Solution
wheel sticks in the workpiece/material
use more radial pressure and swing the wheel forwards and backwards
Cause
Solution
cutting-off wheel used for grinding operations
use a grinding wheel for grinding operations
Cause
Solution
too much side pressure
add only the radial pressure to the wheel
Cause
Solution
different diameter top/bottom flange
use flanges with the same diameter
GETTING THE BEST FROM YOUR CUTTING-OFF
& GRINDING WHEELS
• Decide which material is cut most and that you select the most suitable Flexovit wheel in accordance
with the application chart in this chapter. To use the right wheel for the right material is very important
for the life and cutting/grinding behaviour of the wheel
• Check if the machine is operating correctly and that the machine does not exceed the speed that is indicated
on the wheel
• Use the wheel at the recommended speed indicated on the wheel and the maximum operating speed chart
that you will find later in this chapter
The troubleshooting guide can easily help you recognise and solve problems.
