no expert but my guess
jaws parrallel to each other and square to clamp screw all perp. to slide of jaws.
Check/ fixfirst then at least vise holds well.

Use angle blocks clamped to mill bed..then clamp vise to angle block. Thus under side can be trued.Square to jaws..so jaw face perp.

Then square off top to use as datum.

Re: "buzzing" in HI...in low machine wired in 'star' and in high wired in 'delta' this means machine uses the motor wiring differently in the two cases...fault might be in switch gear...may be one connection off in the delta mode.
