Well,I FINALLY made SOMETHING on the VMC.OK ,hold down the laughter! It's not much but if you started from knowing nothing at all about cnc machines nor ever having run one to rebuilding the damn thing,diagnosing the electrical/electronics issues to learning how to run the thing with no help I must say WHEW!!!!!!! I'm fricken happy as hell to get this simple little thing done. Look out Aluminum ,here I come!
I use aluminum jaws just like that then wedge a piece betwen them raised at the front to take all the "lift" out of the moving jaw, then cut a notch out of the front and rear jaw to hold your material.
Lift? Kurts have the angle lock ball inside. They have almost as much force pushing down on the movable jaw as they do clamping force. They do not lift unless your clamping something that's not parallel.
How often do you take them apart and clean them? If there packed full of chips and the ball is rusted in place your going to have issues. We take them apart and clean/grease them once a week. I have measured ours with zero lift. You have to have the adjusting screw in the back cranked down pretty good too, We torque these to keep everything consistent. We also use torque wrench's on the vice on tight tolerance jobs to keep everything consistent. +-.0005 all day long. Easy money. +-.00002 takes a little more effort.......
Seems to be a bit of disagreement . Sort of like asking 3 lawyers a question and getting 4 opinions. LOL!!!!
