Free Float & self centering

[Guest]

Looking to see if anyone knows of a source for free floating/self centering clamps or even a smallish vise?

 

I've looked at the Carr-Lane Swiftsure stuff but not looking to get into hydraulics

 

Looking to keep it manually actuated

Jergens, Gerardi and Lang come to mind.

5th Axis or Lang vise

[Guest]

I am starting with a 5th axis vise but I have 2 locations that need support, as the 5th axis provides centering on the lower section, I am looking for something that has some free floating/centering ability for the top...

 

Grabbing a forging and I don't want to introduce stress/twist......

 

All of the above is good self-centering but I don't see anything manual that has free floating ability

So you are looking to do a 2 stage workholding? Center on one feature, grip on another?

Yup.....so that the setup is good and rigid

Take a look at hydraulics and use a manual screw pump. Vektek has em for around $300.

I think you could take a self centering vise and make your own center piece and screw to allow it to float, and then add some set screws in the jaws to clamp against the rails to lock them down after clamping.  The center piece of the Lang is removable.  I don't know of any off the shelf that will float.  Alternatively use a stock self centering vise and put the float into the mounting of it.

Technigrip's clamps float completely. It's the bosses on the vise that locate/center.

You have texts coming John...

[Guest]

Thank you sir...THAT IS exactly what I was looking for......

 

Already sent an email to my Rep for more info   

 

Thanks to everyone who chimed in!

Techni-Grip work really well.  I've used them in many applications.

[crazy^millman]

Yes seen the Techni-grip used in many different shops over the years. Great system and they have a lot of off the shelf tombstone stuff for HMC that is really nice.

[Newbeeee™]

I've never seen the Technigrip products.

It looks a good range and it looks nice stuff.

I asked for some models and they send a pretty serious nondisclosure agreement that would have made it illegal for me to modify the models in any way to suit my purpose.  I said no thanks.

[crazy^millman]

They offer the components separate and you can do what every you want with them. Have had many customers use their hardware and others to come with with what they need for their applications. They can word a NDA anyway they want, but unless you are modifying their components for resell than you are stuck. If you are modifying things for your needs then you have no issue doing that.

Well then in all reality you would never be able use it how would you be able to adapt anything to use with it. Totally unenforceable and a completely funny to read. In essence they are trying to put themselves out of business the way I read it. You can just buy one and reverse engineer it and get everything you need.

I'd get it and do what ever I wanted to with it.  As long as you don't publish it, they'll never know.

I don't want to put my company in a bad legal position by signing such a stupid agreement.  There are enough law trolls out there, and going to court costs money even if you're in the right.

[Guest]

Those clauses would NEVER hold up in court.

[Matthew Hajicek - Singularity]

Anyone can sue for anything, even if it would never hold up, and as I said it costs money to go to court even if you're right.  Not a risk I'm willing to take.
