Trunnion tables aren't limited to standard pneumatic clamping. These versatile and efficient machines can also be outfitted with automatic, hydraulic clamping systems to minimize loading error and greatly increase efficiency and spindle time. Over the years, we have made several hydraulic fixtures featuring Vektek Swing Clamps:
You may have seen the video via our instagram account of the Stallion 9/23 featuring the swing clamps in the image above. This trunnion was made for Mako Finished Products. In this case, six single acting clamps are fed with a manifold block that is hooked to an air over oil intensifier. By using a Trunnion Table fixture, the customer was able to machine all three sides of this part in a single setup, greatly increasing the efficiency of their machine, while simultaneously reducing the likelihood of scrap. In order to achieve full 360 degree rotation, we outfitted the HRT-210 with a riser block and created a larger outboard support. This, of course, created concern for tool clearance, but we were able to make it work in this customer's HAAS VF-2. Watch the video:
Similar to the above setup, the following Stallion 9/35 Trunnion Table is also a custom hydraulic fixture in which VekTek Swing Clamps were used.
In this case, the Stallion Trunnion also has a TS 1200 Hydraulic braking system on the outboard support. This created the need for a second air over hydraulic pump to allow both the brake and the vektek clamps to work simultaneously. Unlike the previous design, this part did not warrant a riser block, as 360 degree rotation could be achieved with the standard 6 inch center height of the HRT-210. Watch it in action:
