Due to the simple design and the restriction to this purpose (sampling), these cutting presses can be manufactured and offered at low cost. In general, they are even cheaper than used machines with the same performance. The C-shape shown here has now established itself as the ideal design. Since the reinforced design enables punching of up to 250 t, C-shape tools can now also be used for large sheet thicknesses. This makes it possible to punch from a sheet metal panel that has not been pre-cut - there is no need to pre-cut strips / sheets, e.g. DIN A4. For C-shape punches with a working area (see also TWIN / TRIPLE punches), the punching tools must be changed (<10 seconds). One or two extensions (storage area for up to 8 tools) can be ordered as an option for the change tools.

However, the C design (as a single punch) is only one of the designs we offer. Alternatively, we can also supply the C design as a TWIN / TRIPLE / QUATTRO variant. With these variants, it is “Ready to Go” at any time and without changing tools. Below you will find some delivery examples.
We offer you punching machines with a layout optimized for your needs. For example, the company WUPPERMANN (NL) has a stamping tool which punches a longitudinal sample and a transverse sample in one stroke. We supply system solutions that are optimally tailored to your needs: punching machines with reserves, punching tools that are optimally tailored to your sheet thicknesses and our unique PSM 2000 tensile specimen grinding machine.
ZS1200CN-150 Punching of hardened tensile specimens
Sheets from the area of press hardening / hot forming / hot pressing / hot demforming / hot stamping
At the beginning of 2014, we delivered the first special sample punch ZS1200CN-150 mm stroke for punching samples from hardened samples (keywords: press hardening / hot forming / hot pressing / hot demforming / hot stamping). We were able to convince other customers of this system for taking samples from sheets with a tensile strength of up to 1700 MPa:
- voestalpine Polynorm – Germany – Schwäbisch Gmünd (2014)
- BENTELER- Slovakia – Malacky
- voestalpine Polynorm USA – WHITE GA 30184
- TWB Company, LLC- USA – MI 48162 Monroe (Michigan)
- BENTELER- Czech Republic – Zatec
A special feature of these punches is that sheets with strengths of up to 1700 MPa can be punched. In addition, the user can replace the cutting punches and dies themselves (which wear out more quickly at these strengths). If the appropriate interchangeable punches and dies are available, work can continue after just 10 minutes. The blunt cutting punches and cutting plates can be sent by parcel service for sharpening. Depending on the range of sheet thicknesses, several punching tools may be required here too. Additional punching tools must be provided for other sample shapes.

Double tensile specimen punch ZS 600 + 1000 CN – ThyssenKrupp Finnentrop
The special punch TWIN ZS600+1000 has 2 work spaces built into one load frame. The multi-tools punch in one stroke:
- 2 tensile specimens in rolling direction
- 1 tensile specimen transverse to rolling direction
- 1 tensile specimen diagonal to the rolling direction
- 1 disc for testing the zinc layer

Fully automatic tensile test specimens – SHOUGANG punching machine
In 2008 / 2009 we have completed a fully automatic punching machine realized:
- Sample panels are taken from the strip at the 15 rolling mills
- there they are marked with a matrix label
- These are delivered in special containers (which fit into the punching machine)
- the containers are inserted into the punching machine
- the robot arm (with reading head) identifies the sample panel
- the sheet thickness and sheet size are received from the HOST PC
- the sample panel is removed with a vacuum gripper
- the sample panel size and material thickness is checked
- the sample sheet is inserted into one of the four punches depending on the requirements
- After identification, samples are punched according to ISO6892 (left working space) or JIS (right working space)
- the punched sample slides on a slope to the outside of the system and can be removed there
- the punched remaining panel is placed in the scrap container for disposal
- a new cycle begins
