EPPINGER Manual (Assembling and Handling) for
Driven Toolholder DIN 69880 (VDI)
With a Eppinger VDI driven toolholder every customer gets a high quality product that
provides outstanding technical characteristics:
PRECI-FLEX® adapter system or standard collet chuck
Different kinds of couplings, ref. turret type (e.g. DIN 5480, DIN 1809, etc.)
Adjusting block, ref. toolholder version
Tapered roller bearings
GENERALLY
1. Each driven toolholder has got his own test protocol, that documents the proven
geometrical accuracy .
2. Our tools are completely maintenance-free owing to the used Long-Life-Grease.
Bearings and gears are greased with: Make Klüber, NBU15 Isoflex.
3. Every driven unit was checked for temperature and ride disturbance. This means, that
the toolholder are immediately ready for working processes!
4. Technical information and individual equipment for each tool are available at our
online-database: (http://katalog.eppinger.de).
INSTRUCTIONS FOR TOOLHOLDER CHANGE
Basically: To guarantee an optimal function of the toolholder we require a clean
tooling interface. Only this ensures the highest possible precision of the
handling process.
Loose the serrated VDI-locking wedge of the toolholder station inside the turret.
The coupling of the toolholder should be aligned to the counterpart of the turret
interface.
Insert the toolholder into the turret until it get in contact with the turret surface.
Tighten the serrated VDI-locking wedge*

* If the toolholder is equipped with the adjusting block (e.g. Type B), please tighten the
VDI-locking wedge lightly to allow the alignment by the clamping screws (Pic 3). After
you preset the toolholder you have tighten the VDI-locking wedge definitely!

INSTRUCTIONS FOR ADAPTER CHANGE (PRECI-FLEX® - Interface)
1. Remove the four screws (a) from the base holder.
2. Clean the taper and flat mounting surface from the adapter and the base holder.
3. Install and tighten the four screws (b) with the T-wrench (c)
4. Use the hook wrench (d) to detain the spindle from rotating
The conical and flat face planar interface ensures highest accuracy and rigidity!

For example angular (radial) driven tools (Type B / Pic 1) can be positioned on the turret by
the adjusting block.
Type C (Disc/Face contact-Turret) Type D (Star-Turret)
(Pic 3)
TECHNICAL INFORMATION FOR DRIVEN UNITS WITH INTERNAL COOLANT SUPPLY
1. Don´t run the toolholder without coolant! Danger of overheating!
2. Permitted coolant pressure = 70 bar / 1000 psi.
3. Coolant fluid has to be filtered with minimum 30 micron!
4. In general you are able to modify the toolholder into external coolant supply.
5. Coolant tubes, sealing rings for collet nuts and spindle-sealings are available at our
online-database: (http://katalog.eppinger.de).
BASIC NOTES FOR USAGE
Remove all resources for the assembling (Spanner-Wench, etc.) from the toolholder even
from the working area of the CNC-lathe, BEFORE you start the working process!
MAINTENANCE AND SERVICE
To reach a long lifetime of the driven units, please don´t use strong chemical cleaning
agents. Even don´t use compressed air for wiping the tools and protect all the surfaces with
oil or other anticorrosives.
