VMC, HMC - Side-Mount Tool Changer - Manual Recovery

This procedure tells you how to do a manual recovery on the Side-Mount Tool Changer (SMTC) of a Haas mill. A recovery is required if the SMTC cannot complete a tool change.

Step 1

Push RESET to clear any alarms.

The control attempts an automatic recovery.

Push [A].

Step 2

If the automatic recovery attempt is not successful, the control gives you the (M) Manual recovery option.
Push [M] for Manual.

Step 3

The display shows suggestions to correct the problem.

Follow the prompts as they are displayed.

Use these commands to move the tool changer components:

  • Push ATC FWD or ATC REV to turn the double arm.
  • Push the UP or DOWN cursor arrows to raise or lower the tool pocket.
  • Push ORIENT SPINDLE to reset the spindle orientation and lock it.
  • Push the LEFT or RIGHT cursor arrows to turn the carousel left or right.
  • Push the TOOL RELEASE button to trigger the tool clamp/unclamp.

Step 4

If you press ORIENT SPINDLE, the display shows a warning dialog box.

Push [N] to cancel the spindle orientation if the tool changer double arm will interfere with the spindle when the spindle orients.

If the spindle can safely be rotated and locked, press [O].

Step 5

After the problem has been corrected, the display shows that no further actions are required.
Push [C] to continue.

Step 6

The Pocket Tool Table on the control displays the pocket that is currently in front of the spindle and the tool that is in the spindle.

Make sure that the tool in the spindle and the current pocket match the control's display.


Push MDI.
Push ATC/FWD to test the recovery.
If the tool change recovery is not successful, it is most likely that the machine is mechanically jammed. Contact your Haas Factory Outlet for assistance.
