Tram – Center of B
The purpose of this screen is to locate the center of the B-axis in, with respect to the work piece spindle
axis. This is important because it is used as a reference for defining the tool length, and establishing a
height relationship with the face of the Schunk on the work piece spindle.
The Y-axis should be moved as far forward as possible so that the tool spindle does not collide with the
tram ball in the work piece spindle.
You will have to move the Z-axis down to locate the center of B. Depending on your machine
configuration, this may cause a collision issue with the Tool Probe located behind the work piece spindle.
Proceed with caution, and remove the probe tip or probe assembly as necessary. To remove the probe tip
or probe assembly, use the spanner wrenches provided in your tram kit.
The instructions on the screen will guide you through performing this task (see Figure 3). Utilize the
[MOVE] command to go to the last known center of B position. This should get you close to the proper
location. Make sure that you mount the magnetic base indicator to a stable place on the B-axis that will
allow it to move freely with the B-axis. Once set up, rotate the B-axis in both directions and record the
values on the indicator. If the values are different from left to right then an adjustment in the X-axis is
required. If the values on the sides are equal but different from the value on top of the ball, then an
adjustment in the Z-axis is required. Mastering this technique takes practice, and can be time consuming
if you are unfamiliar with it.
