Description

This standard rotary base precision Machine vise is a cost-effective general-purpose fixture widely used in conventional metal cutting workshops. The main body adopts high-grade gray cast iron with complete stress relief aging to eliminate internal casting shrinkage stress, equipped with full-circle graduated 360° rotary positioning base and wear-resistant trapezoidal screw transmission, balancing stable clamping rigidity and economical procurement cost for daily batch processing.
  1. 360° Graduated Rotary Swivel Base with Independent Lock Bolt
    The bottom circular swivel base is laser-engraved with clear angle scale for intuitive reading, enabling free 360° horizontal rotation. A dedicated side locking bolt firmly fixes the vise at any target angle, eliminating repeated workpiece disassembly and re-clamping when machining inclined holes and sloped surfaces, drastically shortening fixture setup time.
  2. Quenched Replaceable Precision Ground Alloy Steel Jaws
    Fixed and movable jaws are forged from high-hardness carbon steel, fully quenched and mirror precision ground to maintain ultra-high flatness and parallelism. Anti-slip serrated inner faces provide strong friction grip to prevent workpiece sliding during rough stock removal; worn jaws can be replaced separately to lower long-term workshop fixture costs.
  3. Thickened Self-locking Trapezoidal Lead Screw
    Large-diameter trapezoidal screw with built-in self-locking structure delivers stable continuous clamping force without automatic loosening under cutting vibration. Smooth sliding movement reduces hand-cranking labor intensity, ideal for long-shift continuous workshop production.
  4. Anti-vibration Stress-relieved Cast Iron Frame
    Integrated thick-wall box-type cast iron structure undergoes multi-cycle aging heat treatment, effectively absorbing cutting vibration and resisting permanent deformation under conventional rough milling loads, fully meeting the precision tolerance requirements of general machining tasks.
  5. Complete Multi-inch Size Series for Full Coverage
    Four mature mainstream specifications (4/5/6/8 inch jaw width) cover small bench drill mills, medium vertical milling machines and large heavy-duty milling equipment. Each vise adopts independent single export carton packaging, convenient for overseas storage, logistics and bulk delivery.
