Setup Information and Recommendations
Tool “D” (above centreline)
Set B is deflected to position “DF,” relieving the
load by deflecting to a smaller bore, A. Tool “D”
cannot “dig in” because the cut (load) becomes
lighter as it deflects.
Tool “E” (on centreline or below)
Set B “digs in” and is deflected toward position
“EF” and bore C. The larger the load, the larger
the deflection.
Tip of the Insert
This enables the end user to hold closer tolerances,
produce a better finish, and avoid chatter.

Built-in geometries of WIDIA-CIRCLE™ precision
boring bars are based on the concept that the
boring bar shank will always be positioned on
the machine spindle centreline. The cutting point
will be slightly high (against direction of rotation)
except when facing centreline or cutting on
outside diameters.
Use WIDIA-CIRCLE precision setup level or:
1. Use centre height gage and position insert as
shown in illustration.
2. If centre point is unavailable, mark the centre of
the bar stock with a centring punch or square.
Position the insert as shown in illustration.
3. Lay a straight edge on the insert to help position
the insert parallel to the travel or centreline.
NOTE: In some cases, to help reduce
chatter or taper, the insert may
need to be rotated less than
0,25mm but more than
0,05mm above centre.
