Warranty
When using tool holders that are not adjusted, tested and marked as
such by INDEX TRAUB, the warranty for the tool drive is void.
Information on wear parts
Tool holders are wear parts requiring correct handling.
In order to ensure a long service life, compressed air or coolant must not enter the
gap seals of the holders.
Inspection of live tool holders
Tool holders must be inspected at regular intervals (at least twice a
year) for smooth running and play.
The drive pinion and drive clutch of the live tool holders must be sub-
jected to a visual inspection for damage or wear.
If one of the above-mentioned defects is detected during the inspection of the tool
holders, they must be returned immediately for preventive maintenance or repair to
the following address:

Tool holder - Technical Information
TECHNICAL INFORMATION
Tool holders with cooling lubricant supply
Tool holders marked with this symbol must be operated with cooling lubricant (no
dry running permitted).
Tool holders marked with this symbol can be converted from external cooling lubri-
cant supply to internal cooling lubricant supply.
Observe dry running capability of IC attachment!
Cooling lubricant filtering
When using live tool holders with internal cooling lubricant supply, it is necessary to
use a cooling lubricant filter system with a retained particle size ≤50 µm.
Cleaning live tool holders
Live tool holders must never be immersed in cleaning fluid since mixing the clean-
ing fluid with the bearing grease will reduce the service life of the tool holders.
Speed ratio specifications on tool holders
The value to be programmed is specified in the documentation and on the live tool
holders (= the input in the NC program).
nprog = ntool x i
ntool = speed at the cutting tool edge
nprog = speed to be programmed
i = speed ratio in the tool holder
This means the speed increase or speed reduction is not specified as a fraction but
as a number.
This gives speed increase ratios as numbers less than 1.
Example: i = 0.333 (corresponds to i = 1:3)
i = 0.676 (corresponds to i = 1:1.48)
Speed reduction ratios are numbers greater than 1.
Example: i = 2 (corresponds to i = 2:1)
i = 1.333 (corresponds to i = 4:3)

TECHNICAL INFORMATION
Direction of rotation specification
Definition of the viewing direction.
Viewing direction for determining the direction of rotation is always from behind (that
is, from the drive direction) toward the shaft.
On the machine side, the direction of rotation has been set by parameters such that
M03 always denotes clockwise rotation and M04 counter-clockwise rotation at the
interface of the drive pinion of the tool holder.
The direction of rotation given on the holder therefore refers to a “change in direc-
tion within the holder”. M03 and M04 are machine functions to be programmed.
The and arrows indicate the direction of rotation of the cutting edges.
This means:
No reversal of direction of rotation
When the holder drive shaft has the same direction of rotation as the tool cutting
edge, the clockwise direction of run must be specified by M03 (clockwise rotation).
Accordingly, counter-clockwise rotation must be specified by M04.
Reversal of direction of rotation
When the holder drive shaft has the opposite direction of rotation as the tool cut-
ting edge, the clockwise direction of rotation must be specified by M04.
Accordingly, counter-clockwise rotation must be specified by M03.
Example
No reversal of direction of rotation

TECHNICAL INFORMATION
Tightening torque
The tightening torques of the clamping pieces to the tool holder mounting depends
on the shank diameter of the tool holder.
Shank size Tightening torque
ø20mm 8 Nm
ø25mm 20 Nm
ø30mm 25 Nm
ø40mm 40 Nm
Coolant supply
For tools with W-serration and double clamping serration. the 2nd hole for coolant
supply must be closed by the end plug and the seal.
The gaskets on the tool shank and the coolant bushing must be regularly checked
for damages.
Replacement seals for tool shank
The gaskets on the tool shank and the cooling lubricant bushing must be regularly
checked for damages.

Sealing air port
It must be ensured on all machines with sealing air ports that the sealing air ports in
the tool carrier and in the tool holders are sealed/closed with M5x6 mm set screws.

Tool holder - Technical Information
TECHNICAL INFORMATION
Tool holders with fixation
Except for very few cases, all tool holders have been pre-adjusted with
high precision and sealed with the INDEX V bar / TRAUB adjusting bar/
W-serration.
This setting must not be changed.
The INDEX V bar / TRAUB adjusting bar / W-serration ensures positional accuracy
of the tool when re-inserted.
The tool holders are fixed around the shank axis by pins (DIN 69880).
DIN holders can be used.
Double serration of the tool holders allows several uses.
High-pressure unit
The cooling lubricant up to 80 bar (e.g., for deep-hole drilling) is supplied
through the standard cooling lubricant line.
Load limits of live tools
The drive power and torques are indicated in the performance charts. These values
represent the upper limit of the calculated theoretical performance values (average
values). In case of interrupted cuts, e.g., for milling, the load peaks occurring when
the cutting edge enters the material may be much higher than the theoretical torque
according to the performance chart.
The cutter should be selected so that a cutting edge is constantly being
used for cutting during the machining process.

TECHNICAL INFORMATION
Live tool holders
Only the tool located in the working position is live.
The live tool holders are inserted into the mounting bores in the tool carriers just like
non-live tool holders.
Each turret station can accept one live tool.
The motor drives the tool that is exclusively in working position. In addition, the index
drive is actuated by switching using the same motor.
The sealing washer (1) must be removed first.
Tool carrier XYZ VDI40 with 12 stations
1 Sealing washer 12014790
2 Blanking plug 10911003
3 Mounting pin 10682808
Tool carrier XZ VDI40 with 18 stations
1 Sealing washer 12014790
2 Blanking plug 10573819
3 Mounting pin 10682808
Before using the machine, make sure that all mounting bores without
a tool have been closed with a sealing washer and that the gasket on
all tool holders is not damaged.
Any mounting bores not used must be closed with blanking plugs during
machining processes.
