Dual Jaw Bidirectional Synchronous Equal Force Clamping Precision CNC Milling Vice

Dual Jaw Bidirectional Synchronous Equal Force Clamping Precision CNC Milling Vice

Fully quenched solid steel precision bidirectional split synchronous vise with built-in twin-screw synchronous transmission system, available in 4-inch and 6-inch jaw widths. The central fixed partition drives left & right movable jaws to advance synchronously with identical clamping pressure, enabling simultaneous holding of two identical workpieces in a single fixture. Equipped with full mirror ground rigid base, it matches all vertical CNC machining centers and milling machines, ideal for mass batch milling, drilling and tapping to double single-machine processing throughput.

Description

This bidirectional double-opening synchronous vise is a high-efficiency double-station workholding fixture dedicated to mass symmetrical part production. The integral thick alloy steel frame undergoes overall quenching and full-surface precision grinding, eliminating casting deformation defects of cast iron vises. The unique middle partition bidirectional screw linkage ensures balanced clamping force on both sides, solving uneven compression issues of single-jaw vises for paired workpiece batch machining.
  1. Central Partition Bidirectional Synchronous Equal Force Mechanism
    The built-in dual trapezoidal screw linkage structure linked by the middle fixed block delivers synchronous equal-distance travel for left and right movable jaws. Clamping pressure acts evenly on two workpieces simultaneously without unilateral offset or dimensional deviation, maintaining consistent tolerance for paired parts in one processing cycle.
  2. Integral Quenched Alloy Steel Full-ground Rigid Bed Frame
    One-piece solid steel blank construction with complete stress relief and mirror precision grinding on all base, guide rail and jaw mating surfaces. Ultra-high flatness, parallelism and perpendicularity withstand long-term heavy rough milling without precision loss, far exceeding the stability of standard cast iron vises.
  3. Double-station Batch Processing Capacity Design
    Single vise unit supports clamping two independent blanks at once, drastically reducing workpiece loading & unloading frequency and improving workshop equipment utilization rate. Optimized long narrow layout saves T-slot table space for multi-fixture layout on one machine worktable.
  4. Universal Replaceable Jaw Mounting Structure
    Multiple standard threaded mounting holes are pre-reserved on fixed and movable jaws, supporting quick installation of custom aluminum soft jaws, serrated anti-slip hard jaws and V-shaped special jaws for thin-wall, irregular and cylindrical workpiece clamping.
  5. Two Mature Standard Sizes for Medium & Small Parts
    Two mainstream specifications (4" / 6") cover miniature precision hardware and medium mold blank processing scenarios. Each vise adopts an independent shockproof export carton to protect precision ground surfaces during overseas logistics transportation.
