Operation
Most tools are supplied together with an operating guide. Correct operation cannot be ensured and danger to personnel
and machine cannot be excluded unless these operating instructions or information given in this catalogue are observed.
Precision
The individual tool planes incorporate hardened and precision ground X and Y centering prisms and separate Z-supports.
That means positoning of pallets and fixtures is done automatically.

Service and maintenance

Since the clamping system is subject to chemical and ­physical influences, maintenance and service has to be performed
with special care.

Technical modification
All products shown in this catalogue are subject to ongoing improvements and developments; we reserve the right to make
modifications without notice.

Quality according to ISO 9001 and EN 9100

All products of Carl Hirschmann GmbH are manufactured using the latest production methods. All products are submitted
for ISO 9001 and EN 9100 (air and space industry standard) quality assurance.

Warranty
We provide a 12 month warranty for all clamping system parts starting from the invoice date, and assuming correct use
and maintenance as specified has been observed.
The warranty is restricted to replacement or repair, free of charge, of any defective parts. Claims arising from improper use
or handling shall not be considered. Warranty claims must be submitted in writing.

 Reference Set HPF5000 PrisFix
Low-cost Referencing of Electrodes and workpieces

The HPF 5000 PrisFix reference set is a cost-effective solution for

referencing copper or graphite electrodes and workpieces in the Carl
Hirschmann 5000 clamping system. The function of a pallet
(X-Y-Z reference base) is divided into single, very cost-effective com-
ponents. These are glued into the electrode or the workpiece and clam-
ped in a Carl Hirschmann clamper until they are fixed by the adhesive
(takes a few minutes). The costs for a pallet are eliminated. Both the
clamping journal H6.611 for the clamping series H6... and the clamping
journal H5.611 for the clamping series H8... can be used.

Brilliantly simple
Prepare blank in 8 steps

1.) Blank (≥ 50x50 or ≥ Ø 67 mm) 2.) Make bores Ø5, M5 and M12

4 x Ø5
4 x M5 M12x1,25

5 .) Blank with completely mounted parts 6 .) Clamp blank with mounted parts for
centering of reference prisms into clamper.

characteristics
• Repetitive accuracy ≤ 0,002 mm
• Inexpensive, no pallet necessary
• Material bond connection (no shifting)
• For electrodes and workpieces from □ 50 mm / Ø 67 mm

Clamping journal

All pallets and holders and also the Reference Set HPF 5000 are delivered without clamping journal, it is to be
ordered separately.
Depending on series of clamper (H6.xx or H8.xx), the corresponding type of clamping journal must be used. In
case of a new purchase the use of clampers series H6.xx and the clamping journal H6.611 is recommended.

Two clamping journal designs are available

• Clamping Journal H5.611 -short clamping journal (use

only for clampers series H8.xx)

• Clamping journal H6.611 - clamping journal with inte-

grated gripper surfaces for automatic change (use only
for clampers series H6.xx)

Hollow axis clamper µ-PrisFix 5000

With Hollow Axis Clamper µ-PrisFix 5000 workpieces are positioned quickly and precisely in a hollow axis
or directly on machine table. This offers the possibility of 360 degree machining of inner contours, even
complex shapes are possible.
The innovation is based on proven Carl Hirschmann technology of patented µ-PrisFix Clamping System for
positioning of workpieces in machine tools with a repetitive accuracy of ≤0,5µm.

 Clamping System 5000
µ-PrisFix Flat Clamper

Installation height of the ultra-flat clamping system µ-PrisFix Flat is significantly lower compared to current
systems available on the market. Clamper and especially designed workpiece holder together are only 35 mm high.
As manual clamping system with an attractive price-performance ratio and the short resulting time of amortiza-
tion µ-PrisFix Flat is the ideal entry product for applications on rotary indexing tables. It is suitable for numerous
applications such as wire EDM, sinking EDM, EDM drilling or laser machining. The clamping system is completely
rust-proof and can be used in deionized water or other fluids.
Due to its different hole patterns the new clamping system can be used on many single-axis and two-axis rotary
indexing tables of Carl Hirschmann. Also customized hole patterns can be realized and the clamper can be
mounted directly onto the machine table or to another interface.

 Rotary Indexing Tables
For high precision EDM

Our circular dividing tables and rotating spindles are specially designed for use on EDM, HSC and laser machines.
They are completely sealed (IP68) and can therefore be used in the dielectric of sinking and wire EDM machines.
Rotary indexing tables considerably extend the application range of the EDM machine. Spiral cuts, helices, high-pre-
cise pitches etc. can be easily produced even out of materials that are difficult to machine.
