Hi Guys,
I have only used my 5th axis vises thus far in my machining career of 1 year. But I would like to improve accuracy/consistency of my parts.
I currently square my stock (5”x4”x1.5” 316SS) and load it into the top portion of the vise jaws, which is only 0.1” tall, but holds rigid with the vise teeth (part is loaded with 5” side running along to X, 4” side to Y). I never exceed max torque of the vise, 75nM. Mill away, nothing overly aggressive, although I do use a 1” Helical end mill for the heavy roughing so it does need some clamping force, leaving about 0.150” plate remaining on bottom of stock, create some locating bores through the part. After I flip the part over, I find that the remaining “plate stock” is far from flat anymore.. all I can assume is that I am bending the stock when I clamp it in the jaws? Is that even possible with a 6” vise and stock of this size?
I am considering creating some custom fixturing with Mitee Bite pitbull clamps on all 4 sides of the squared stock so that there is no bending or lift.
Any wisdom to what’s wrong with the current setup or what would not work in the proposed custom setup would be appreciated!
