Description

This QH12 rotary base milling vise is a classic heavy-duty manual workholding fixture specially designed for general metal cutting equipment. The whole body adopts high-strength gray cast iron with complete stress relief annealing to eliminate internal processing stress, matched with replaceable precision steel jaws and 360° rotary positioning base, realizing flexible multi-angle clamping and stable rigid holding under heavy cutting loads.
  1. 360° Graduated Swivel Base with Quick Lock
    The bottom integrated rotary base is engraved with full-circle angle scale for intuitive angle reading, supporting free horizontal rotation within 360°. A side lock bolt firmly fixes the vise body at any target angle, eliminating repeated workpiece re-clamping for inclined surface and angled hole machining.
  2. Replaceable Hardened Precision Ground Steel Jaws
    The movable and fixed jaws are made of high-hardness alloy steel with full surface precision grinding to guarantee flatness and parallelism. Anti-slip serrated inner surfaces provide strong friction grip to prevent workpiece sliding during rough milling and heavy stock removal; jaws can be individually replaced after long-term wear.
  3. Anti-vibration Rigid Cast Iron Main Body
    Thick-wall integral cast iron frame undergoes long-time stress relief heat treatment, effectively resisting permanent deformation under continuous heavy cutting. The closed box-type structure absorbs cutting vibration, ensuring consistent dimensional accuracy of machined workpieces in mass production.
  4. Reinforced Trapezoidal Lead Screw Clamping Mechanism
    Large-diameter trapezoidal lead screw cooperates with a long leverage crank handle to generate large stable clamping force with smooth, low-effort operation. Precision thread fit minimizes backlash and maintains reliable clamping performance after thousands of clamping cycles.
  5. Complete Standard Size Lineup & Standard Export Packaging
    Five mainstream specifications cover small bench drill to large vertical milling machine matching demands: QH1280 / QH12100 / QH12125 / QH12160 / QH12200. Small-size models are packed 4 units per export carton; large heavy models adopt single-piece independent carton packaging for safer overseas transit.
