Precision turning of 155 mm artillery shells with the EMAG USC 850

The USC 850 turning machine impresses with its generous machining area with a maximum turning diameter of 700 mm, specially optimized for 155 mm calibre artillery shells. High positioning and roundness accuracy ensure the ammunition subjected to machining has first-class ballistic properties. This technical accuracy is essential to meet the highest standards of safety and functionality.

The USC 850 features an advanced 45° inclined bed design that offers outstanding static and dynamic rigidity. This reduces vibrations during the machining process to a minimum, which contributes significantly to the quality of the machined surface. The robust tailstock with a quill diameter of 150 mm ensures workpiece stability even with long and heavy artillery shells.

A 12-station turret, optionally equipped with powered tools, also enables flexible complete-machining in a single setup, thereby minimizing time and costs. The integrated coolant supply directly to the cutting edge also ensures extended tool life and improved surface quality of the machined components.

The powerful main spindle of the USC 850 offers a continuous output of up to 30 kW and a peak output of up to 37 kW over 30 minutes. This allows efficient and fast machining of high-strength materials typically used in the defense industry. Thanks to cylindrical roller bearings, the machine achieves a high spindle rigidity, which ensures consistently high precision even during heavy machining.

EMAG offers integrated automation concepts that are tailored to your individual production requirements. The result is fully automated and efficient production lines that are specially tailored to the high safety and quality requirements of the defense industry. EMAG systems thus enable reliable, precision and economical machining of 155 mm artillery shells in both large and small batches.
