Hermle has introduced the C 250 machining center as a means of entry into five-axis machining. Like the company’s C 400 model, the C 250 features a modified gantry design and mineral-cast machine bed. The NC swiveling rotary table of the five-axis version enables machining of workpieces weighing as much as 661 pounds (300 kg). The traverse path inside the working area spans 600 × 550 × 450 mm for a vertical table clearance of 550 mm and a 688-mm door opening, providing optimal conditions for safe and simple crane loading, the company says.

The control panel for the Heidenhain TNC 640 CNC has a full-color 19" TFT flat-panel monitor, and can pivot from the working area to the tool loading point. This feature enables the operator to more easily enter tool data into the tool table control. A Hermle integrated control unit provides the operator with optimum support for complex milling tasks. In addition to the company’s Hermle Information-Monitoring Software (HIMS) package, the unit also comes with the Maintenance-Diagnostic System to facilitate efficient diagnostics and status-oriented maintenance in the event of malfunction.

An integrated tool magazine holds 30 tools with the option to incorporate two additional magazines for 50 or 88 additional pockets. To extend its range of application, Hermle offers features such as additional magazines, various cooling and chip systems, extractors, tool breakage monitoring/measuring, and touch probes.


  • Aluminum Molds In Three Weeks Or Less

    While aluminum molds are commonly used to create prototypes or to serve as stopgap bridge tooling, they are starting to receive greater attention for production work. This shop’s approach to creating aluminum molds in one day to three weeks is the same for each of these situations.
