Spindle Orientation adjustments

What is spindle orientation and how is it determined?

Spindle orientation is when the spindle finds its home position just like a regular machine tool axis accept that its called orientation. Orientation is often needed to align the tools up properly in order to perform a tool change.

Orientation could miss position for a number of reasons. Crash, sensor, axis misalignment causing a crash are the most common. Orientation is usually set with either parameters or a pot on the circuit board or drive.

Remember axis alignment at tool change position must be correct before adjusting orientation alignment. Orientation is often set parallel with an axis. Make sure you check the tool changer arm alignment slowly rotating through before running a tool change at full speed.

How to adjust spindle orientation?

Basically its relatively simple. Just change the parameter, usually only press reset and then orient the spindle again and check the alignments with the tool changer arm. Move the tool changer arm manually by either turning the fan on the back of the motor or sometimes there is an allen wrench or wrench flat. Depending on the machine and if it is a servo motor driven then it sometimes can be rotated by the hand wheel
