Rotary die
The 300 Series rotary die design is optimized for extrusion of medical tubes, particularly invasive applications, due to its reduced diameter. By rotating the tooling in relation to the material flow, a rotary head increases the wall strength of an extrusion, allowing a thinner wall with less material – often resulting in cost savings by reducing the amount of expensive polymer required.
Benefits include only rotating the die, randomizing any gauge bands or thickness variations, and, in some cases, improving material properties of the end product. The 300 Series can easily accommodate various tubing sizes with the Guill cam-lock design reducing setup and changeover times.
Rotary heads are well-suited to multi-lumen tubing plus various high-end extrusions with interlocking layers or multiple striping requirements.

Modular machine
The M70 MILLTURN enables reliable precision machining with high pull-in forces at the tool interface and a wide range of additional options for productive deep-hole drilling processes and special technologies. With the capability to machine workpieces weighing up to 5,000kg, the MILLTURN is suitable for heavy-duty applications.
The M70 MILLTURN features a working area concept for working lengths of up to 8,000mm and a swing diameter up to 850mm. Its modular system can be tailored to each customer’s requirements. The machine offers a disc tool magazine or chain magazine with up to 200 tool stations and capacity for tools weighing up to 35kg with a maximum length of 900mm. In addition to automatic tool changes, the setup process can also take place during machining, allowing the magazine to be tooled for different orders without any loss of time. Two magazine variants are available for heavy special tools weighing up to 200kg each.
Thanks to targeted chip breakage optimization and the use of high-pressure coolant (HPC) up to 150 bar, machining costs can be noticeably reduced. Ultra-high pressure coolant (UHPC) ensures even greater efficiency, lower tool costs, and improved process reliability during machining.

Laser measuring system
The LC54-DIGILOG is the most compact laser measuring system in the LaserControl DIGILOG series to date, specially developed for tool measurement and monitoring in micro-machining. Measurement and testing times have been reduced up to 60%, with system laser optics perfected for microtool requirements. An optimized beam shape and a 30% reduction in the focus diameter allow for absolute accuracy.
The MicroTool mode is activated automatically for microtools and enables another significant increase in measuring accuracy for precise measurement of the most delicate tools.
While classic digital/switching laser measuring systems generate only a few signals by shading the tool, the LC54-DIGILOG generates several thousand measured values per second, with dynamic adjustment of the measurement speed to the nominal speed of the tool. Each cutting edge is measured individually, enabling precise comparison between the shortest and longest cutting edges. This results in a repeat accuracy of 0.2μm (2σ) and automatic detection of concentricity errors caused, for example, by contamination on the tool holder. The system also identifies any dirt or cooling lubricant adhering to the tool and excludes it from the measurement result.
