This procedure outlines how to set the spindle orientation offset on the HSK-A63 Spindle.

Tools Required:

• The HSK-A63 Tool Changer Alignment Gauge needs to be purchased. It can be bought from TAC Rockford.

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 [1] should be installed to the double arm [2] 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.

Record the MACHINE Z Position value [1].

Multiply the MACHINE Z Position value by the value in Parameter 33 Z RATIO (STEPS/UNIT).

 Note: The value of Parameter 33 Z RATIO (STEPS/UNIT) is not the same for each machine.

In this example the value of Parameter 33 Z RATIO (STEPS/UNIT) is 554872 [2].

(Z position value) x (Z Ratio) = Calculated value

-0.0093 x 554872 = -5160

Push [EMERGENCY STOP].

If the calculated value is negative, add the value to Parameter 64 [1]. If the calculated value is positive, subtract the value from Parameter 64 [1]. Refer to the examples that follow.

Example 1, negative calculated value:

The calculated value = -5160.

The initial value of Parameter 64 = 172509.
