/ Applications /  Spindle direction

Spindle direction measurement is made on machines such as lathes, boring machines, arbores, milling machines etc.

Measuring spindle direction
When measuring pointing direction for e.g. a machine spindle relative the machine bed, a spindle pointing in the opposite direction or a bearing journal, the laser transmitter (preferrably D146) is placed in the center or near the center of the spindle. When the spindle is rotated 180° the center of rotation of the laser beam is calculated where the detector is mounted. This center of rotation is stored in the display unit. Now move the detector a known distance and calculate the center of rotation for the laser beam once again. The difference in values for the center of rotation in detector position 1 and 2 is the angular error for the rotation of the spindle relative the machine bed.

Spindle direction for Arbores and Milling machines
Measuring pointing direction in an arbore or milling machine can be made with the table as reference or the movement of the table as reference. By doing this we are able to see if the table is parallel to the machine bed.
