Hey guys, looking for some input on the best process to use from someone that has some sheet metal experience.
I make some parts that use stainless cages bent into rectangles that are sandwiched between 2 aluminum plates. The material is 20ga perforated stainless (3/16" holes, 1.4" center to center) Currently I get 4x4 sheets cut into 1.1" wide strips and then trim to length myself. The issue with the laser is the burr/dross, it's small but the product is an air filter for an engine so I end up having to sand and wire wheel the burrs off.
I have reached out to a number of shops in the area (San Diego) and no one seems to want to shear it, they all say we would laser it and that shearing wont be as accurate. What sort of tolerances can be held with cnc shearing something like this? I want the cuts square to the sheet/perforations and the strips need to be a consistent width.
Here are some photos of the parts and the burrs I am getting from the laser.
