    Berthiez RVU – grinding, turning, milling, measuring in one set-up and continuous dressing of the grinding wheel

    Bumotec s191V – Precision work: The case of the new UR-111C wristwatch

    Bumotec s191H – Diamond setting operation performed with accuracy and efficiency

    Dörries VC – The XXL sub-contractor HACO produces large parts with precision in the range of hundredths of a millimeter

    Droop+Rein T – Elegant and fast: The portal machining centre machines extremely heavy workpieces in a single clamping process, thereby significantly reducing machining times. The crankcases can also be machined in their operating position.

    Benchmark: Tripod technology is still the most advanced in the world when it comes to machining complex aluminium

    Sprint Z3 – parallel kinematic machining head

    Heckert 800 X5 MT - Among many features, the machining centre impressed Zwicker with its axis configuration with the X- and Y-axis in the tool and the Z-axis in the rotary swivel table. A vacuum clamping table was required for thin-walled aluminium parts.

    The Heckert DBF 1000 machining centre is particularly suitable for highly efficient heavy-duty cutting of heavy housings weighing up to 4,000 kg, such as on the fluid ends.

    Starrag LX 051 – When it’s all about speed and precision. Starrag developed the LX series specifically with the highly precise, efficient, simultaneous five-axis machining of turbine blades in mind.

    Starrag NB 151 - Its rigidity and excellent damping properties allow higher cutting values while also reducing tool wear.

    Starrag NB 151 - Machining blisks and impellers rapidly and reliably in a single step saves both time and money. Thanks to the five-axis Starrag NB 151, which has been specially designed for such machining processes, users from the aviation, aerospace and energy sectors can benefit from these advantages.
