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 (dual station block coming early June, compatible with the fixed jaw base).
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. 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)
Comes with the following
FV4 Fixture Vise
Pair of 1.2" tall, 4" wide, 0.5" thick aluminum softjaws
3/4" long 1/2" diameter dowel pins for the fixed jaw to fixture plate interface.
Basically, a vise that is ready for use right out of the box!
Replacement parts will be listed soon (although no one has asked me for any yet, but I understand service is nice to have).
