Adjustment Of Bore Diameter - WOHLHAUPTER VarioBore 536 Mode D'emploi

When using this outside turning insert hold-
er, this rotated installation position means
that a diameter adjustment is required in the
manner opposite to the one described in
the „Diameter adjustment" point (Page 17):
Turn in + = Diameter is reduced
turn in – = Diameter increased

Clamping (Fig. 10)
The slide is fastened in place using thread-
ed clamping pin ① (tightening torque
3 Nm (26.55 in. lbs.). This helps to prevent
influences such as machining or centrifugal
forces from changing the diameter. The
slider must be clamped during machining.

The adjustment parts could be
damaged otherwise.
4.2 Adjustment of bore diameter (Fig. 10)
Please observe sequence:
1. Release threaded clamping pin ①
2. Turn scale ② to adjust tool diameter.
• On tool presetting device
• On machine using gage cut or trial
drill
• 1 turn of scale:
0.5 mm (.020") adjustment in Ø
• 1 scale mark:
0.01 mm (.001") adjustment in Ø
• 1 vernier scale mark:
0.002 mm (.001") adjustment in Ø
2.1 Readjust tool (increase Ø) readjust scale
to required value
or
2.2 Reset tool
• Determine value set on tool
(Fig a, scale value 21)
• Turn scale back by one half-turn, left
direction of rotation (Fig. b)
• Set new (smaller) scale value
3. Tighten threaded clamping pin, tighten-
ing torque 3 Nm (Fig. c, scale value 20)
The path of the slider is restricted. Any at-
tempts to adjust against the end stop may
damage the tool.
