Description

This QM16 fixed base angle lock milling vise is a rigid workholding fixture optimized for fixed-angle batch machining, without a rotary swivel base to maximize overall structural rigidity. The thick-wall cast iron body undergoes complete stress-relief annealing to eliminate internal forming stress, paired with the exclusive 45° inclined force-splitting transmission to solve the floating workpiece defect common in standard flat vises.
  1. Patented 45° Angle Lock Zero-lifting Clamping Mechanism
    Internal 45° inclined wedge structure converts horizontal tightening force into synchronous vertical downward pressure. Workpieces are firmly pressed flat against the vise base surface without upward warping, removing dimensional errors and surface chatter marks caused by workpiece lift during heavy stock removal and mirror finish milling.
  2. Fixed Integral Base for Maximum Clamping Rigidity
    Canceled the bottom rotary swivel base of universal vises; the one-piece thick cast base mounts directly onto machine T-slots via bolt slots. No rotational clearance gaps, delivering far stronger anti-vibration performance for long-term continuous heavy cutting and high-speed precision machining.
  3. Replaceable Hardened Precision Ground Alloy Steel Jaws
    Fixed and movable jaws are forged from high-hardness alloy steel with full surface precision grinding to maintain ultra-high flatness and parallelism. Anti-slip serrated inner surfaces generate powerful friction grip to stop workpiece sliding during rough milling; worn jaws can be individually replaced to cut workshop fixture costs.
  4. Thick Anti-deformation Cast Iron Box Frame
    Closed thick-wall box-type cast iron construction with long-duration stress relief heat treatment effectively absorbs cutting vibration and resists permanent deformation under heavy loads, sustaining consistent clamping precision for mass production runs.
  5. Complete Multi-version Size Lineup
    Full series covers small bench mill to large vertical machining center matching requirements: standard base, lightweight A-type compact base, and long extended opening L-type for oversized blanks, with jaw widths ranging from 54mm up to 265mm. Each vise ships in an independent export carton to avoid transit collision damage.
