Schunk’s Tendo E compact is a universal toolholder for applications such as milling, drilling, and reaming with extended lengths in CAT 40 (4”) and CAT 50 (6”). Both work with long reach applications and in multi-axis machines, the company says.

This hydraulic expansion toolholder can transfer torques of up to 520 Nm (384 foot-pounds) at a 20-mm clamping diameter and are suited for high volume cutting.

With vibration damping and runout accuracy of less than 0.003 mm (0.0001”) at 2,5 × D, the compact protects the machine spindle and the cutting tool from damage. According to the company, the hydraulic expansion toolholder works across the application range from rough milling to finish operations such as reaming and fine milling.

In roughing operations, tool cost reductions of up to 40 percent have been achieved and tools can be changed with an Allen key. Common spindle connections are available, including interfaces HSK-A63, SK40, BT40, CAT 40, and CAT 50.

  • What's Possible At 10,000 RPM

    High-value work doesn’t have to demand a high-cost machine tool.

  • Too Small To Touch

    Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.

  • Don’t Forget The Drawbar

    The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
