Help with milling issue

--- Quote from: crueby on May 03, 2025, 06:59:23 PM ---The screwless vise type is what I  use. Rather than a horizontal screw at the back of the jaw, there is a screw running diagonally down through the jaw to a cross pin that engages a series of slots underneath. They come in a variety of sizes and are not too expensive.  There are also other types of milling vises, but I don't  have experience with them  so I will  let others speak to them.

I know which ones you mean, I have one, maybe I should use it for work like these bearings, rather than the other type.

Jasonb:
We discussed the issues with teh "screwless type in the other thread.

The Warco one would not be so bad if you mad used parallels and knocked the work down after tightening the jaws.

Have you tried that old Abwood one?

On the CNC and for some manual work I use one of teh ARC versatiles in 80mm width (also have the 100) which seems to work well and jaw lift is not really measurable. https://www.arceurotrade.co.uk/Catalogue/Workholding/Machine-Vices/ARC-Versatile-Milling-Vices-with-swivel-base

Main one I use on the Manual mill is the Vertex K4 which has a small amount of lift but nothing a copper hammer can't sort out. Mine came from Chronos but I don't think they do them now but they are about on the net.

Couple of measurements of liftI took comparing a 90mm screwless and the two above

I haven't tried the Abwood one, but will do; the only issue with it is that it doesn't open very wide for larger work. I'll give it a go before spending any further $s. Those Arc ones look good as do the Vertex and aren't too crazily priced. I bought quite of bit of cheapo stuff when I first started out and gradually over time have had to replace them with better quality stuff......not an unusual story I'm guessing!  :)

BTW switching to the precision vice sorted out the issue straight away; I had to complete a few passes to bring the work back to an even keel

uuu:
I have vices that claim to stop jaw lifting, but don't really work.  The Abwood design is good - the moving jaw is supported over a decent length - there are gibs you can adjust to keep things tight - the thrust from the screw is up where the jaw is, not below it.

The abwood is a milling vice i have used them 6""ones but they were worn out  .replaced one i used with a hydraulic   8"   weighed 95 kg used that for years.
but that was for heavy milling and for mostly hot work die steels.
they still need the material to be knocked down to be in the right position i used a lump of copper 1 1/4"dia 6" long
