Milling heads - Import export

The vertical lathes of the TVU product line of Berthiez are especially suited for machining engine and turbine components, which are primarily used in the aerospace industry as well as for alternative and classical power generation. The TVU vertical lathes are characterized by a complete cast design, highprecision static and dynamic positioning as well as longlasting reliability. Advantages of the TVU vertical turning lathes are, completely cast iron construction, high static and dynamic axis stability, high accuracies and long term reliability. For higher flexibility the machine can be equipped with several pallet change systems and adaptable milling heads. The optional Yaxis table traverse will permit the turning, milling and grinding of complex components in a single clamping.

Gear hobbing on CNC lathes without B-axis Years ago, EWS was the first tool manufacturer to offer gear hobbing heads in its standard range, and has continued to develop the holders for gearing technology ever since then. With this technology, it became possible for the first time to produce external gearing on machines without a Y/B-axis. In contrast to a standard milling wheel holder, the tool head of the EWS modular cutter can be swivelled about the axis of the shank. This offers users the advantage of substituting a B-axis with a comparatively small investment. In the meantime, module 3 has become commonplace on VDI40/BMT65/BMT75 machines. The tool heads have become more stable at the same time as being more user-friendly. The alignment system using a sinusoidal profile has come into widespread use and saves considerable alignment and setup times. Operating instructions, flyers and press reports can be found in our download portal Video: Gear hobbing on the
