In this week's highlighted CNC 4th Axis fixture, we are utilizing PAWS Workholding Wedge Clamps, the Stallion 9/20 Quick Change, the Lyndex Nikken CNC 302 Rotary Table and Jergens Ball Lock Workholding. Our main concern with this setup was cutting out time consuming setups and increasing part density. Prior to utilizing the tools mentioned above, our customer was machining just one part and one setup at a time. This particular part has 5 angles that need face-milled, as well as drilled and tapped. We were able to cut all of these out, allowing the operator to only open the doors on the machine once every eight parts!
The combination of the Lyndex Nikken Rotary Table and the Stallion 9/20 Quick Change Trunnion Table allowed us full 360 degree rotation of the aluminum blanks. Without this, we would not have been able to reach all 5 sides of the part. Customized for the CNC 302, the Trunnion Table 4th Axis fixture bolts directly to the faceplate of the rotary table. The entire assembly is also mounted on a baseplate, which allowed for an easy installation.
There are huge benefits to using modular workholding such as these PAWS Wedge Clamps. Should we have used a regular vise, we would have been limited to a maximum of two parts per cycle. While this is still better than the previous method of doing one part and one angle at a time, why machine two parts when you can machine eight? The small and low profile nature of the wedge clamps allowed us to truly utilize the entire 20" working surface of the Trunnion Table.
The Jergens Ball Lock Mounting System added an incredible amount of efficiency to this setup. While the wedge clamps do a fantastic job of increasing part density, the ball lock system allows the operator to load a second sub plate offline while the first is being machined. This cuts the time in between cycles to less than a minute. The thumb screws included with the Jergens product make swapping out the plates incredibly efficient and simple.
Overall, the partnerships that Martin Trunnion Tables holds with these forward-thinking companies allowed us to greatly increase the throughput for the end user.
