Trunnion Table Fixtures for KOMA Precision Rotary Tables

Trunnion Table Fixtures for KOMA rotary tables

Compact, versatile 4th Axis Solution attached to a KOMA RBS-160R

We have been working closely with our partners, KOMA Precision, for years to build fixtures for manufacturers using their rotary tables. Today we are going to review some of the workholding solutions that we have put together and the applications that these designs are best used for. The first concept involves the RBS-160R rotary table, the Stallion 5/18 Trunnion Table, and the Orange Vise Delta IV compact vise. The Stallion 5/18 is primarily designed for smaller rotary tables, making it the perfect fixture for this particular model. Orange Vise also offers ball receivers, which we are using here, to allow for fast and repeatable reorientation of the Deltav IV vise. With that said, this 4th axis fixture can be used for two, smaller parts or one large part when the vises are turned 90 degrees.

4th Axis Pneumatic Clamping Fixture Featuring SCHUNK Workholding

Autonomous clamping added to the 4th Axis is often the perfect solution to a fully automated vertical milling machine. Our partners, SCHUNK, offer a wide range of pneumatic clamping products that take the efficiency and productivity of our products to a different level. Here we are featuring the SCHUNK KSP-160 PLUS pneumatic vises, the Stallion 9/20 Trunnion Table, and the KOMA RWA-200. While you can't see it in these renders, a rotary union resides on the back end of the rotary table, which keeps the air lines from tangling while the 4th axis Stallion is rotating. Pneumatic clamping allows for more precise part location, resulting in tighter tolerances, less operator error, and the possibility of using a robotics solution.

Stallion 9/23 Trunnion Table with Triag Int. Workholding

When building 4th Axis Workholding fixtures, it is often a priority to come up with a solution that can be used for a variety of parts. The goal is often for these fixtures to be a universal solution for all of the customer's parts, not just one. With that said, modular workholding devices are often utilized to allow for Immense setup flexibility. Triag International Workholding provides a modular workholding system that accomplishes this. Their "power clamps" can be moved anywhere along a serrated base rail, allowing for parts of any length or quantity to be machined. They can also be mounted on standard, two inch grid, allowing you to use the fixtures that you already have in house. We are utilizing the RWA-200 in this concept, which allows for an incredible 550 lbs, leaving us assured that our entire assembly will be easily rotated by the KOMA indexer. Check out this animation for a representation of this concept:

Shelf Unit Trunnion Table attached to RBS-160R

If you own a vertical machining center, you will know that it is often difficult to justify purchasing a fixture that will take up your entire machine table. We developed the shelf unit trunnion tables out of pure necessity: we needed something small that was still just as efficient and productive as our standard, but longer units. Here, we are featuring the KOMA RBS-160R with single, double, triple, and 4-sided unit trunnion tables. The single and double sided configurations feature the rocklock bases from 5th axis workholding along with the V552 self centering vises. The 3 and 4 sided models instead feature the V5100X vise; this style is best suited for smaller, high volume parts.
