To a great extent, economical use of cutter drums depends upon proper maintenance. Changing flail
shafts before they become excessively worn
and begin to oval out the shaft holes can significantly
increase the life of the drum. If you run a machine with badly worn flail shafts you can easily
destroy a drum in just a few hours. These shafts are only surface hardened in order to maintain their
internal strength. This is why it is important to replace them as soon as the grooves are 1/5 of an
inch or 5mm deep.
Changing the shafts early provides the following advantages:
• The drum shaft holes will not wear as fast thus increasing drum life.
• Breakage of shafts can be avoided, thus saving a great deal of downtime refitting the
machine.
Recommendations:
• When working with five or eight point Tungsten Carbide tipped cutters or special milling
cutters, replace the shafts every fifteen to twenty hours of operation.
• When working with steel cutters change the shafts every time new cutters are installed.
• Change the entire cutter/drum assembly after 3 sets of cutters have been used up, if not
sooner.
