Tools Required
1. Steel Straight Edge

The Magazine axis motor is utilized for positioning of the magazine to the tool changer provisional place. When magazine place 1 is aligned to the tool changer provisional place, the axis position will be 360.000 or 0.000. The secondary external encoder is utilized for positioning of the magazine to the tool loading station. Both of these positions are determined by using a steel straight edge and determining the deviation between the two guides. Once these deviations has been determined, the calculations can then entered in the CM axis Machine Data.

Step 1:

Move magazine place 1 (empty location without tool cartridge) to the conveying station towards tool changer.

Step 2:

Position the linear axes such that the tool changer door is easily accessible:
- Z-axis (rotary table) away from the machining unit.
- Y-axis (Machining unit) down.
- X-axis (frame) away from the tool changer door.

Step 3:

Check measuring system position display:
- Select the "Service axis/spindle" window. Softkey sequence from the basic menu: Diagnostics - Axis diagnostics - Service axis .
- Select axis 9 M_CM.
- Read off the "Position actual value measuring system 1" parameter. The measuring system 1 must report 0 degrees.

Step 4:

Select the "Tool change individual functions" main menu.
Open tool change door using the "tool change door" individual function.
Switch off motors.
Open work area safety door and secure to prevent closing.

Step 5:

Determine deviation between target and actual position.

  • Set Position
    • Theoretically, the locating face of tool holder should be at the same height as the locating face of provisioning place. A difference of + or - 0.3 mm is permissible.
    • In practice, the tool holder should be somewhat higher, to a level so that the cartridge continues to runs evenly during the next function test. This gives you some reserve, should the chains give under heavier tools and expand further over the course of time.
  • Measure deviation in accordance with Fig. -7. Ensure that the two locating faces are parallel for measurement.

Step 6:

Converting the deviation to angular degrees. Observe positive and negative values according to the following tables:

Step 7:

Remove support from the tool change door.
Before closing the safety door, ensure that nobody is in the work area.
Close work area safety door.
Turn on machine on at the main switch.
Switch on motors.
Close tool change door using the individual function.

Step 8:

Insert EKS key, select setup, mach. dataMD, Axis MD.

Step 9:

Enter adjustment value:

  • Select "setup" - "Machine Data" - "Axis-machine data" menu.
  • Select the tool magazine using the softkeys Axis+ and Axis- (axis 9, M-CM).
  • Select machine datum MD 34090[0].
  • Add the adjustment value to the previous contents of MD 34090[0]: Subtract negative correction values. Key sequence:
Key sequence for addition Key sequence for subtraction Remarks Example
= = An input window appears showing the previous contents of the machine datum: 360.00000000
+adjustment value -adjustment value The typed value is appended top the value in the input window. 3600000000-0.15
input input The input window is closed. The result in displayed in the machine data listing. 359.85000000

Step 10:

Turn the main switch off and on again. The actual position of the tool magazine is displayed in the actual value display of the main operator panel.

Step 11:

Checking adjustment and readjust if necessary
Run the tool magazine through its complete cycle again in both directions.
Check height of the conveying station. Readjust deviations. Proceed as previously with the first adjustment.

You have checked the adjustment and not found any deviations.
Machine switched on.
Work area safety door is locked.
Motors are switched on.
Tool change door closed.
Move a magazine place with tool cartridge to the conveying station towards the tool changer.
Open tool change door with individual functions.
Use the "Tool traverse attachment" individual function to move the tool cartridge to and fro between conveying station and tool changer provisioning place. At the same time, observe the tool cartridge movement. The tool cartridge must move back and forth without jerking.
Close tool change door with individual functions.
If the tool cartridge transport was not perfect, read just the conveying station and repeat all checks.

Step 12:

Because measuring system 2 sits flush over the tool setting station, tensioning has only a slight effect on this side. After repeated tensioning however, the deviation may exceed tolerance permitted here.

The cartridge transport between conveying station and tool changer provisioning place is smooth.

Step 13:

Move magazine place 33 on the conveying station towards the tool changer. Magazine place 1 (empty location without tool cartridge) is located on the conveying station towards the tool setting station.

Step 14:

Open intermediate door:
- Select the "Tool change manual mode" main menu.
- Open intermediate door via individual function "Tool setting station/tool magazine safety door".
Synchronize chain-type magazine with the tool setting station via individual function "chain synchronization".

Step 15:

The control switches over to measuring system 2. The chain-type magazine moves up by the offset between the two measuring systems.

Unlock tool setting station safety door with intermediate door open:
- Select "Additional functions manual mode" main menu.
- Unlock tool setting station safety door via individual function "Tool setting station safety doors/safety door".

Open maintenance door of the tool magazine.
Switch off machine at main switch and secure against being switched on again.
Secure the intermediate door to prevent it from lowering.

Step 16:

Determine the difference between conveying station and tool setting station
1 Tool Loading Station
2 Locating face of the tool setting station
3 Locating face of the tool holder
4 Tool holder

Step 17:

Determine deviation between target and actual position.

  • Set position:
    • Theoretically, the locating face of the tool holder should be at the same height as the locating face of the tool setting station. A difference of + or - 0.3 mm is permissible.
    • In practice, the tool holder should be somewhat higher, to a level so that the cartridge continues to runs evenly during the next function test. This gives you some reserve, should the chains give under heavier tools and expand further over the course of time.
  • Measure deviation in accordance with image. Ensure that the two locating faces are parallel for measurement.

Step 18:

Converting the deviation to angular degrees.
Observe positive and negative values according to the following tables:

Step 19:

Remove support from intermediate door.
Before closing the maintenance door, ensure that nobody is behind the guard panels.
Close the maintenance door of the tool magazine.
