Easily Achieve Accuracy and Precision

Includes:

• Tramming Tool
• Compatible with the MR-1 Dial Test Indicator (Sold Separately)

This device allows the operator to directly measure spindle tram error so that the spindle can be shimmed/adjusted to eliminate the error.

Achieving exceptional surface finish with minimal steps between passes requires a spindle that has minimal tram error. Tram error is the measure of perpendicularity between the axis of the spindle and the XY plane of the machine. A spindle with too much tram error presents the cutting tool at an angle to the workpiece which has the tendency to create a stepped surface finish. The effect is magnified when using larger tools such as a fly cutter.

This tool sweeps an 8” diameter and should be used directly on the baseplate after it has been faced.
