Stallion Trunnion tables for HAAS rotary tables and machine tools

While the Stallion Trunnion Table can be designed and manufactured for any CNC rotary table on the market, we have more experience making fixtures for HAAS rotary tables than any other brand. We are often faced with limitations due to machine table size, machine travel and rotary table capabilities. In this post we are running through potential 4th axis applications specifically for your HAAS rotary tables and how they resolved certain limitations. 

Stallion 9/23 Trunnion Table With HRT-210 Rotary Table

In our first workholding solution, we are featuring the HRT-210 and the Stallion 9/23.  In this case, we were faced with a job that included many parts at many different sizes. With that said, we knew we needed to use a modular workholding system that would allow us to machine parts at many different lengths. The solution: Triag International Workholding.  This vise system features a base rail that allows for the clamping modules to be moved to different positions, which creates immense setup flexibility as the Triag product can be used for a wide variety of parts. The deck of the trunnion table has a two inch grid pattern with hardened bushings in every other hole, which works seamlessly with the triag rail and power clamps.  On the support end of the fixture resides our TS400PNU braking system. At over 400 ft. lbs of clamping torque, this pneumatic brake keeps the trunnion table extremely rigid when making heavy, off center cuts to the workpiece. While this animation instead features a KOMA Precision Rotary Table, it displays this concept perfectly: 

Stallion 9/20 Trunnion Table With HRT-160 Rotary Table

The second setup features the HRT-160 and the Stallion 9/20 Trunnion Table. One of our most often faced obstacles in fixture design is making sure that the customer's parts can be rotated 360 degrees. The HRT-160 has a center height of just 5 inches, which prompted us to provide a 1" riser block for this customer's rotary table while simultaneously adjusting our outboard support center height to match this 6 inch mark. This adjustment allowed for our customer's parts, along with the 5th Axis V552 vises, to be rotated 360 degrees.  This design also features our TS1200 Hydraulic braking system, which has 500 ft. lbs of clamping torque at 100 PSI. Similarly to the TS400PNU from the previous setup, this feature is designed to allow for heavy, off center milling and drilling of the customer's workpiece. 

Stallion Triangle Trunnion Table With HRT-310 Rotary Table

Our last fixture highlighted in this post features a HAAS HRT-310 with a Stallion Triangle Trunnion Table attached. This design again features the Triag International Rail and Power Clamps.  The triangle configuration offers the immense benefit of tool clearance. Because the trunnion table features three sides on 60 degree angles as opposed to four sides on 90 degree angles, there becomes less concern about investing in longer tools. The bolt-hole pattern on the end plate of the fixture is customized for the HRT-310, allowing the manufacturer to easily insert and remove the trunnion when necessary, Additionally, the entire assembly resides on a baseplate, which results in a very short and simple setup time. 

All of these fixtures offer similar benefits for different situations: less handling and setup time, more machining time. This method of lean manufacturing results in greater machine output, as well as greater employee output. 

Stop Handling, Start Machining.
