Description

This Q13 large-opening rotary base milling vise is a heavy-duty manual workholding fixture developed for large-size workpiece machining. The whole thick-wall box body is made of high-strength gray cast iron with complete long-time stress relief annealing to eliminate internal forming stress. Matched with ultra-long travel trapezoidal screw and 360° rotary positioning base, it realizes stable rigid clamping for extra-large workpieces under heavy cutting loads.
  1. 360° Graduated Swivel Base with Quick Lock Mechanism
    The bottom integrated rotary base is engraved with full-circle angle scale for intuitive reading, supporting free horizontal rotation within 360°. A side locking bolt firmly fixes the vise body at any target angle, avoiding repeated disassembly and re-clamping of oversized workpieces for inclined surface and angled hole machining.
  2. Ultra-long Travel Trapezoidal Lead Screw for Oversized Clamping Opening
    Adopts thickened large-diameter trapezoidal lead screw with extended movable jaw stroke, realizing super-wide maximum opening to accommodate long and wide metal blanks that ordinary vises cannot hold. The precise thread fit ensures smooth low-effort operation and stable huge clamping force without backlash after thousands of cycles.
  3. Thickened Integral Cast Iron Anti-deformation Main Body
    Closed thick-wall box-type cast iron frame undergoes full stress relief heat treatment, effectively resisting permanent deformation under continuous heavy rough cutting. The integrated thickened base structure absorbs cutting vibration to maintain consistent dimensional precision of machined large workpieces in mass production.
  4. Replaceable Hardened Precision Ground Alloy Steel Jaws
    Fixed and movable jaws are manufactured from high-hardness alloy steel with full surface precision grinding to guarantee high flatness and parallelism. Anti-slip serrated inner faces provide powerful friction grip to prevent workpiece sliding during heavy stock removal; worn jaws can be individually replaced without changing the whole vise.
  5. Ergonomic Long Crank Handle & Complete Size Range
    Equipped with extended long leverage crank handle to boost labor-saving clamping operation. Five mainstream specifications cover medium to large processing equipment matching demands: Q13136 / Q13160 / Q13200 / Q13250 / Q13320. All models adopt single independent export carton packaging to avoid collision damage during overseas transportation.
