Have any of you made any fixture plates similar to this image? I do not have access to funds for the hydraulic portion (yet). I have more and more jobs requiring clamping to a 2 7/8" x 3/8" bar stock in 6061-t6. I am machining the top then flipping over and machining the bottom, no outside contouring thankfully and there is a round nipple that gets done on the 1st op that I can locate off of for the 2nd op.
Without using hydraulics, what would be the cheapest/easiest way to create clamping force required? I like to push my 1/2" endmill fairly rough at around 180ipm when I can if not more so I dont need these things popping out and destroying $70 endmills left and right.
I have been doing 4 per double vise with versagrip's without any issues and then softjaws for the 2nd op. I would like to use a single fixture plate that takes up the entire work envelope of the machine if possible. 2000 of these things a month really add up in time and toolchanges not to mention forearm fatigue!
I would prefer to make all components in house to some degree, tolerance on these parts are .005 or worse and the 2nd op makes absolutely no difference, its just to remove some material on the back side for weight. (and they get welded to a tube as a cap in the end)
so the question is...how would YOU do it?
