Gantry Machines

Typical industries include aerospace, the automotive industry, tool and mold making, model making, the semiconductor industry, defense, and energy technology.

Zimmermann portal milling machines have a modular design and can be configured in various sizes with different travel ranges. This allows the machine to be flexibly adapted to different production requirements.

The FZP/U lines offers a wide range of milling machines that meet various production requirements. The “U” stands for Unibody, meaning the machine bed is integrated and offers flexible installation options. In contrast, the “P” stands for Performance, where the machine bed is recessed into the foundation to allow for ground-level access and automatic loading.

The 32-42 series are equipped with a thermosymmetrical gantry and offer high precision even in their standard configuration, which typically meets our customers’ requirements.The thermosymmetrical box-in-box design minimizes thermal influences that could negatively affect the machine’s geometry. For structural and drive components, the highest priority is placed on accuracy, and the assemblies are arranged to minimize thermal expansion. This ensures process stability, even with fluctuating temperatures or process heat, and guarantees a high degree of precision. Especially during long machining times or when working with large workpieces, this design is a key factor in achieving consistent milling results and perfect surfaces..

All Zimmermann machines feature very high dimensional accuracy:
• Positional and volumetric accuracies in the low micrometer range. Machines in the 32-42 series achieve a positioning accuracy of up to ≤8 µm and a volumetric accuracy of up to ≤50 µm as standard
• Thermal stability values that ensure precise results even during longer processes. The accuracy values can be configured to standard or increased accuracy depending on customer requirements.
• The 22/27 series are manufactured as standard in accordance with recognized international accuracy standards, including VDI/DGQ 3441 and ISO 230-2. These standards define test procedures for the positioning and repeatability accuracy of tooling machines.

Thanks to the high precision, time-consuming rework is often eliminated. This saves labor time, material, and thus significant costs. In addition, components can be delivered faster, more flexibly, and with higher quality.

All Zimmermann portal milling machines are equipped with modern CNC controls, with the following options:
• Heidenhain TNC 7
• Siemens SINUMERIK ONE
These controls support complex 5-axis machining strategies and can be integrated into modern CAM environments.

The portal milling machines can be equipped with various additional systems, such as:
Extraction hood | Coolant system | Probing system | Minimum quantity lubrication | Room extraction | Chip conveyor | Vacuum system | Tool measurement systems | Tool changer
These options allow the machine to be adapted to different production environments and materials.
