I picked up a nice Röhm 120mm wide jaw machining vise today. It is a hydraulic vise meaning that once it closes down and touches the part in the vise then as you turn the handle it uses hydraulic pressure inside the vise to clamp the part.

It also has the jaws that have pins built in to locate a part or support a part. I just have to blow air in the side of the jaws on which ever row I want to extend and they pop out. Sort of like built in parallels or locating pins. One just pushes the pins back in you don't need. I had never seen this feature but what a time saver for relocating a part in the vise or for repetitive parts.

I know this is all old hat and boring for you experienced machinists but I thought it was really cool.

I have one of those hydraulic vises and prefer my Kurts to it.

Those are cool jaws. I have never seen them before but they look handy.

Cool vise jaws/inserts. Anything that indicates they were made by Rolm? Perhaps a clever machinist?

I will have to go look for a brand name on them. If you look in the close up of the jaws you will see the small holes on the end of the vise jaws. That is where I blow the compressed air in and pop out the pins. Brian Rupnow would have some down homey words to describe how cool these vise jaws are to use. Maybe he will add his words of wisdom to the thread as he isn't making a video it seems.

They are the 'Vario-Tec' jaws, made by Lang in Germany.

I would be interested to know what you didn't like about your hydraulic vise. I thought the ability to have a consistent clamping pressure would be a plus.

What an interesting vise,, i have never seen one before!!

Are these fairly rare or?

Got an air over hydraulic vice for the big CNC, only has about 6mm of movement to tighten but the power pack is able to be controlled by the CNC so it can switch coolant off, stop spindle and open the vice ready for the next part.

Neat vice jaws, can see a good use for them if you arrange the pins so you can get 2 or 3 to lie in a 30, 60 or 45 degree layout.
Plus if you use them as parallels you never get the problem id the parallels trapping before the work.

Any idea what a 6" set of jaws cost? Those are sweet!

Wish I could recall where I have seen those jaws before...anyway, been casually keeping an eye open for a vise, thinking Glacern but recently saw the Tormach CNC vise advertised...

they have an optional "Pin Jaw", little less high tech (no air), fewer pins and in a pattern that allows 90/60/30/15 degrees...the "Super Soft Jaw" maybe useful as well

I was told they cost in the area of 500 Euros for the pair. I looked at the Lang site but no prices were given.

That link is well worth a look, 3rd link down inside to link above, Modular Work holding.

Just need Tiffie to knock a set up to show us how easy it is to do.

I am in Heaven! This Röhm vise and the pin jaws are the best thing since sliced bread. Maybe even better. I really like the hydraulic vise. I don't have to wonder if I should lean on the handle a little more. Consistent clamping every time. Just the mass of the Röhm vise makes a huge difference in how my mill handles some heavy cuts.

Rohm makes nice stuff, I have a very heavy duty 8" 4 jaw made by them, it must be 75 lbs. They made Firearms at one time.

If it's the same RÖHM, they still make airguns:

BF,

Very interesting vise, indeed. Thank you for sharing.
