Umbrella Tool Changer
Tool Loading Tools are loaded into the umbrella tool changer by first loading the tool into the spindle. To load a
tool into the spindle, prepare the tool and then follow these steps:
1. Ensure the tools loaded have the correct pull stud type for your mill.
2. Enter Handle Jog mode.
3. Organize the tools to match to the CNC program.
4. Take tool 1 in your hand and insert the tool (pull stud first) into the spindle. Turn the tool so that the two cutouts
in the tool holder line up with the tabs of the spindle. Push the tool upward while pressing the Tool Release button.
When the tool is fitted into the spindle, release the Tool Release button.
5. Press the “Next Tool” button.
6. Repeat Steps 4 and 5 until all the tools are loaded.
Umbrella Tool Changer Recovery
If the tool changer jams, the control will automatically come to an alarm state. To correct this, push the Emergency
Stop button and remove the cause of the jam. Push the RESET button to clear the alarms. Push the Recover
button to reset the tool changer.
CAUTION! Never put your hands near the tool changer unless the EMERGENCY STOP button is pressed first.
Side Mount Tool Changer Recovery
If a problem occurred during a tool change, a tool changer recovery needs to be performed. Enter the tool changer
recovery mode by pressing the Recover button. Once in tool changer recovery mode, instructions are given and
questions are asked to perform a proper tool changer recovery. The entire tool changer recovery process must be
completed before exiting. If the routine is exited early the tool changer recovery must be started from the beginning.
Side Mount Tool Changer Door and Switch Panel (if equipped)
Mills such as the MDC, EC-300 and EC-400 have a sub-panel to aid tool loading. The Manual/Auto switch must be
set to "Auto" for automatic tool changer operation. If the switch is set to "Manual", the other two buttons, labeled
CW and CCW, are enabled and automatic tool changes are disabled. The CW and CCW buttons rotate the tool
changer in the clockwise and counterclockwise directions. The door has a switch which detects when the door is
open.
Operation
If the cage door is opened while a tool change is in progress, the tool change will stop and not resume until the
cage door is closed. However, any machining operations that are in progress will continue.
If the switch is turned to "Manual" while a tool change is in progress, current tool changer motion will be com-
pleted. The next tool change will not execute until the switch is turned back to "Auto". Any machining operations
that are in progress will continue.
The carousel will rotate one position whenever the CW or CCW button is pressed once, while the switch is set to
"Manual"
During tool changer recovery, if the cage door is open or the switch is in the “Manual” position and the Recover
button is pressed, a message is displayed telling the operator the door is open or is in manual mode. The operator
must close the door and set the switch to the automatic position in order to continue.
