1.3 Intended Use
Use the tool-grippers only for the intended use. Insufficiently clamped tools or work-pieces, failure
to comply „safety and accident prevention regulations“, and the use of work-pieces and our
products on machines that are not intended for this propose, can result in personal injury and
damages to the clamping devices. In this case, we shall assume no liability. Do not apply force
during assembly, disassembly and operation; this could damage the clamping device or the
machine.
1.4 Initial start-up
A function check is implicitly before initial operation of the tool-gripper. To ensure a safe and
precise operation of the tool-gripper during machining, a sufficient clamping force must be
provided. Check the clamping force.
See Checklist for Installation p.16
The tool-gripper, especially the function surfaces must be clean and lubricated sufficiently. It is
strongly recommended to grease with “lubricant metal (Metaflux)” (special grease).
METAFLUX-lubricant metal paste Nr. 70-8508
Pay attention:
Mixture with other greases is not allowed!

Never exceed the axial and radial forces specified on the tool-gripper. Check the clamping force
regularly!

2 Product-description
The Ortlieb Tool-Gripper distinguishes by a simple outline in the spindle and compact dimensions.
The rubber-bonded clamping segments are designed for maximum clamping force and high
revolutions, especially for HSC-machining and are rated for a life time of 2 mio. load alternations.
The large central cooling feed provides a secure cooling when using coolant lubricant or MQL
(minimal quantity lubrication).

Description
1 Segments
2 Draw-bolt
3 Pin
4 Ring spring
5 Disk springs
6 Drawbar
7 Tool
8 Spindle
Function:
Milling spindles on machine tools are usually fitted with conventional spring loaded tool clamping
systems. The tool-gripper operates on pulling force.
The six rubber-bonded clamping segments were spread equally by the taper on the draw-bolt and
draw-in the tool-holder by the 30°-shoulder into the taper of the machine spindle. During clamping,
25% of the clamping force is dispensed upon the taper, 75% upon the front surface. Thus, also
with high machining forces it is granted, that the tool never lifts from the front surface.
To change the tool, the disk springs were compressed, usually by a hydraulic cylinder. The draw-
bolt is pushed by the drawbar to the front, releases the clamping segments and pushes the tool by
force out of the spindle taper. The ring spring provides a closing of the clamping segments which
release the tool for changing.

2.1 Tool-Grip
®
Standard
The Standard-Tool-gripper for high clamping forces and high
revolutions with large central cooling feed. Maintenance friendly
and persistent.
By its simple design and few components, this tool-gripper is mounted quickly, extreme
maintenance friendly and persistent.
Your benefit:
- Designed for high clamping force and high revolutions (Technical p.11)
- Large central cooling feed for cooling lubricant or MQL
- Maintenance friendly and persistent
2.2 Tool-Grip
®
Repair-kit
The repair-kit tool-gripper allows to restore and rework worn
spindles by regrinding the taper and the front plane surface.
Designed especially for spindle-services and the rework of used spindles. Worn spindles were re-
grinded on the front plane surface and the taper. This repair-kit allows to double the life time of
spindles without the loss of clamping force or accuracy which safes money for expensive spare
parts.
Your benefit:
- Cost efficient: Allows rework and regrinding the machine spindle
- Easy replacement of the tool-gripper
- Available in standard version, maintenance-free or with holding function

2.3 Tool-Grip
®
Maintenance-free
The version with ceramics on the draw-bolt is complete
maintenance-free up to 3 mio. load alternations with constant
clamping-force. Afterwards, just the clamping segments have to be
replaced. The draw-bolt can be reused.
Function:
The incomparable sliding properties and wear-resistance of the steel-ceramics combination is
undisputable since the introduction of the hybrid-bearing. Ortlieb offers those advantages for the
first time ever for tool-grippers.
Insiders are aware of the problems of constant decreasing clamping force caused by a lack of
maintenance. As long as the maintenance instructions are kept, constant clamping force is
guaranteed over the total life time. Reality shows that regular maintenance and re-greasing is not
accomplished with the required care. Result: the clamping force decreases rapidly and the life-time
of the clamping system is extremely shortened (black line).
After initial lubrication, the tool-gripper with ceramics stands 3 million load alternations with
constant clamping force without maintenance. (red line)
Your benefit:
- After initial lubrication maintenance-free up to 3 mio. load alternations with constant
clamping force
- Available as standard, repair-kit and with holding function

2.4 Tool-Grip
®
with holding function
These tool-grippers are especially designed for even faster
changeovers. The already released tool is held safely in the spindle
with a defined force till the tool changer pulls the tool out of the
spindle.
Function:
By replacing the standard tool-gripper by a tool-gripper with holding function (p.11) faster
changeovers are possible.
Connection dimensions and the stroke are the same to the standard version. During the release of
the draw-bolt pushes the tool-holder 0.2 +0,2 mm out of the taper of the spindle. The tool-holder is
held on the 30° shoulder by clamping segments with small slots in a distance of 0,5 - 0,6mm to the
front plane surface of the spindle. When the tool-holder is pulled out by the tool-changer, the
clamping segments with the slots act as a spring with adjustable holding force. When the tool-
changer pushes a tool-holder in the spindle, the clamping segments were compressed and hold
the tool-holder on the 30°-shoulder in a distance of 0,5 - 0,6 mm to the front plane surface of the
spindle.
Your benefit:
- Faster changeovers due to holding function
- Simply replace the standard tool-gripper with same installation dimensions
- Tool-grippers with different holding forces on demand
Technical advices:
- Blow-out air: Force which occurs by blow-out air has to be lower than the holding force
- Tool-weight: Limiting the tool weight is strongly recommended
- Release velocity: To ensure a safe tool-holding, decreasing of the release velocity can be
necessary.
