HydraVise Features & Benefits
- Massive Back Jaw is part of the vise base, not screwed or doweled on. Assures least jaw deflection possible.
- Replaceable hardened and ground jaw plates. Large variety of special jaw plates available, including Vee-, Serrated and Pull-Down Jaws.
- Movable jaw assembly protects and encloses lead screw. Accurately ground setup surface behind removable jaw plate. Facilitates checking of workpiece.
- Self-contained, high-pressure differential power mechanism. Available in hydraulic, mechanical and air-hydraulic.
- Removable crank handle is standard equipment for all vises. No crank extension necessary.
- Shoulder on high-pressure mechanical and hydraulic spindles limits pressure to the designed maximum. No overloading of system possible.
- Pressure indication rings on hydra-spindle facilitate graduated pressure setting. Each ring indicates one additional ton of pressure.
- Two hardened and ground steel cross pins allow instant adjustment of the movable jaw to the small or large clamping range. Jaw assembly may be pulled off the guideways to facilitate cleaning the vise; also makes larger vises easier to lift and move.
- ProVise has a narrow base style for close spacing of vises side-by-side. Ledge facilitates clamping to machine table.
- Strong l-beam design and flame-hardened ways make for the sturdiest base possible.
