Application Spotlight: Stallion L-Series Trunnion Powers Productivity in Mazak Machining Center

At Martin Trunnion Tables, we’re all about helping shops simplify multi-sided machining. One of our recent setups—featuring a Stallion L-Series Trunnion with a 110” x 10” working surface—is a perfect example of how the right workholding configuration can transform machine tool capability.

Built for Large-Scale Precision

This L-Series model was purpose-built for a high-mix, high-volume manufacturer running a Mazak vertical machining center. The working surface spans an impressive 110 inches in length and 10 inches in width—ideal for long, multi-part fixture runs. A precision-ground center support was added to provide additional rigidity and eliminate deflection across the full span of the trunnion.

The body is made from Class #35 cast iron, a material known for its excellent vibration damping and dimensional stability. This means the customer can confidently machine challenging materials or tackle heavy drilling without sacrificing accuracy.

Powered by KOMA Precision’s RWB400 with SSB Brake

​At the heart of the setup is a KOMA Precision RWB400 rotary table, equipped with the SSB Braking system. This rotary delivers the torque and holding strength required to keep the 110" trunnion firmly locked during aggressive cuts—especially critical when dealing with large or off-center parts.

The SSB brake adds an extra layer of rigidity by applying direct clamping pressure across a large surface area, which helps eliminate any potential movement during indexing. This is a big deal for repeatability, especially when working with long fixtures and multiple components.

Fast Changeovers with Carr Lane Carr Lock™

Speed matters, and that’s where Carr Lane’s Carr Lock™ system comes in. The quick-change fixture plates mounted to this L-Series trunnion allow the operator to switch setups with just a few turns of a wrench—no loose fasteners, no re-indicating. That kind of repeatability and efficiency is a game-changer when trying to reduce spindle downtime and improve throughput.

A Perfect Fit for the Mazak

This trunnion was custom designed to integrate seamlessly into a Mazak vertical machining center, maximizing the machine’s fourth-axis capability. By utilizing the full working envelope and rigid support structure, the customer can now machine up to five faces of a part in one setup, reducing handling time and ensuring tighter tolerances across complex parts.

Why It Matters

This application is a textbook example of how trunnion tables aren't just for small parts or short runs. When designed correctly, they can unlock the full potential of a VMC—even for long parts or heavy-duty applications. The integration of KOMA's RWB400, Carr Lock workholding, and our own precision-machined cast iron platform brings the perfect balance of rigidity, speed, and flexibility.
