COMPACT FIXTURE VISES
The FV4 is a 4" compact all steel construction vise 100% designed and made in the USA for existing fixture plates with 1.25" center to center hole spacing. It is useful for holding oversized parts, several parts in a high density workholding configuration, and fits machines from the Tormach 440, two on a Pierson Pallet, welding setups, to full sized VMCs
​
Accessories Coming Soon (maybe 2024 in this order)​
-
Dual station block for FV4 (will also function as updated fixed jaw)
-
Side finger slots to handle moving jaw easier
Eta later
-
Full length vise base with dual station capability
-
Automation upgrades
​
Features
-
100% steel construction
-
Hold parts larger than conventional vises
-
Moving jaw is spring loaded so you don't have to retract the jaw by hand. It also preloads the jaw into the base, preventing ingress of chips.
-
Serrated teeth allow for semi coarse position (travel range of 1.7"). This means you have to unbolt and adjust less when setting up.
-
The wedge itself has a travel range of 1/8" (for final clamping)
-
Dual station capability
-
Compatible with fixture plates with 1.25" bore/thread spacing (SMW, Tosa Tool (wide body bases only), etc)
-
High stress components made from 4140 PH high strength alloy steel
-
Ground faces. The bases of the fixed jaw and moving jaw are ground to match each other. It is designed to be a reference in Z for parallels or soft jaws. Bases are also ground to 0.750" so that long work pieces can be held on multiple vises.
-
Base is made from 4140 alloy steel and hardened to Rockwell C 40+.
-
Includes a standard bolt pattern for soft jaws (the same as a Kurt DX4)
-
These may be upgradeable with a low profile pneumatic/hydraulic autocloser in the future
-
Jack screws included (to make it easy to remove any components with pins)
-
Made in the USA
-
Clamping force:
-
1600 lbf @ 20 ft-lbs
-
3200 lbf @ 30 ft-lbs​
-
4400 lbf @ 40 ft-lbs (nearly identical to a Kurt DX4)
