This procedure outlines how to set the spindle orientation offset on the HSK-A63 Spindle.
Note: Make sure to purchase part number 440.135.163.000.
Double Arm Alignment Half
Install the respective Alignment half into the double arm.
Note: The bottom alignment half  should be installed to the double arm  so that the larger slot is installed into the double arm key as shown.
Spindle Alignment Half
Install the respective Alignment half into the spindle.
Make sure the spindle alignment half is correctly installed into the spindle such that it is fully seated with the taper.
Note: If it is not fully seated, then the tool-release icon will show up on the screen. If the tool-release icon is not showing up when the spindle alignment half is on in the wrong direction the TRP clamp switch will need to be adjusted, refer to the HSK-A63 - Spindle Drawbar - Push Out procedure to adjust the switch.
Enter service mode.
Press [RECOVER] to enter recovery mode. Then press [M] to enter manual recovery.
Press [ORIGIN] to move the spindle to TC position, then jog the z-axis up so that the spindle alignment half will allow clearance for the double arm alignment half.
Press the down arrow to move the double arm until the double arm says [Clamp/Unclamp] in the Tool Changer Status Summary.
Jog the z-axis back down until the two alignment halves mate correctly .
Insert the Alignment pin  to ensure the alignment halves are properly aligned.
Note: The alignment pin does not need to be flush with the alignment half, but it does need to engage both alignment halves.
With the Alignment Pin still in the (2) halves, insert the Orientation pin into the Double arm Half.
Rotate the spindle until the Orientation Pin engages both the spindle half, and the double arm half of the alignment tool.
Set Orientation Offset, while both pins are still in the alignment halves.
Go to the PARAMETER tab then navigate to to FACTORY tab.
Locate parameter 4.082 .
Press [S], then [F3] to set the Spindle Orientation.
