APPLICATION NOTES
ROUGHING
ø24.37-43.70
Up to ø32.68 the bridge tool can be connected to the machine spindle over a tool shank, but only on a machine with good spindle taper,
good spindle bearings and with the normal retention force available. For the range between ø32.68-43.70, roughing is possible with the
bridge bolted on to the machine spindle. If vibration occurs use just one cutting edge.
ø>43.70
Roughing is not recommended
FINISHING
ø24.37-43.70
Finishing is possible with the bridge tool connected to the machine spindle over a tool shank, providing that the machine spindle is in
good condition.
ø>43.70
The bridge tool must be bolted on to the machine spindle, either directly or if required over a special flange.
CONNECTING THE BRIDGE TO THE MACHINE SPINDLE
The bridge tool can be connected to the machine spindle over a tool shank (Fig. 1) or it can be bolted on to the spindle face (Fig. 2).
A bolted connection is recommended for bore sizes ø43.70 and bigger.
