Description

This QM16 angle lock milling vise is a high-precision industrial workholding fixture built to solve the common workpiece lifting defect of ordinary flat vises. The integral thick-wall cast iron body undergoes full stress-relief annealing treatment, matched with a patented 45° angle lock transmission structure and rotatable positioning base, delivering stable zero-float clamping accuracy under heavy cutting load.
  1. Patented 45° Angle Lock Zero-lifting Clamping Mechanism
    The internal 45° inclined force splitting structure converts horizontal clamping force into downward vertical pressure synchronously during tightening. Workpieces are tightly pressed against the base surface without upward floating, completely avoiding dimensional deviation and surface chatter marks caused by workpiece lifting during heavy stock removal and finish milling.
  2. 360° Graduated Swivel Base with Quick Lock Bolt
    The bottom rotary base is engraved with full-circle angle scale for clear visual reading, supporting free horizontal rotation of the vise body within 360°. A side lock screw firmly fixes the vise at any target angle, reducing repeated re-clamping procedures for inclined hole and angled surface 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 guarantee ultra-high flatness and parallelism. Anti-slip serrated inner faces provide powerful friction grip; worn jaws can be disassembled and replaced separately to extend the whole vise service life and save workshop cost.
  4. Anti-vibration Deformation-resistant Thick Cast Iron Frame
    Closed thick-wall box-type cast iron structure with long-time stress relief heat treatment effectively absorbs cutting vibration and resists permanent deformation under continuous heavy cutting, maintaining stable consistent clamping precision for long-term mass production.
  5. Complete Standard & Extended Long-opening Size Range
    Covers mainstream specifications from small bench mill to large vertical machining center: QM1660 / QM1680 / QM16100 / QM16125 / QM16160 / QM16160L / QM16200 / QM16200L (2 extended long-opening variants for extra wide blanks). Every single vise adopts independent export carton packaging to prevent collision damage during overseas transit.
