CENTRO
provides quick and precise location of the centers of bores and shafts.
With the CENTRO, bores and shafts can be easily and precisely centered.
The CENTRO is clamped into a tool holder and inserted into the spindle of
the milling machine. The machine spindle is then positioned near the bore
or shaft that is to be measured, and rotates at low speed. The probe tip
of the CENTRO then slides along the inside or outside surface of the diameter.
Initially, the probe tip will be deflected and the amount of deflection
is registered on the large dial. The stationary dial face does not turn
with the spindle and therefore can always be seen by the operator. The position
of the spindle must be corrected until the hands of the dial indicator stop
moving. The spindle axis is now perfectly aligned with the diameter center.
The perpendicularity of a surface to the spindle may be inspected or adjusted
in the same way. Concentricity errors of the spindle may be controlled or
adjusted as well. Tramming of lathe turrets is also possible with the CENTRO.
Shafts and bores can be measured with the same CENTRO, with a simple switch
of a button, adjusting the direction of tension.
Concentricity errors of the spindle or the clamping are compensated without
the need of adjustment. The large easy to read dial face makes quick and
accurate readings possible. The probe tips are interchangeable. There are
several different probe tips to chose from for multiple applications. |
