Description

This QGG precision tool maker vise is a professional ultra-high accuracy fixture dedicated to mold precision machining, completely different from general milling Machine vise s. The whole body is forged from monolithic alloy steel, processed by overall quenching and cryogenic stabilization aging to thoroughly eliminate internal material stress, ensuring zero dimensional deformation under long-term continuous precision clamping. All sliding rails, jaw clamping planes and bottom mounting datum adopt mirror precision grinding to reach micron-level flatness and parallelism.
  1. Monolithic Fully Hardened Alloy Steel Ultra-Stable Body
    One-piece solid steel blank forming, overall quenched to HRC58-62 high hardness, matched with cryogenic aging treatment to lock long-term dimensional stability. Full stroke flatness & parallelism tolerance controlled within 0.003mm, meeting strict precision requirements of surface grinding and electrical discharge machining.
  2. Self-locking Anti-wear Precision Trapezoidal Lead Screw
    High-precision trapezoidal thread screw with wear-resistant coating, built-in self-locking function to avoid clamping force loosening during hours of uninterrupted grinding/EDM processing. Knurled rotary knob delivers non-slip fine manual adjustment, providing uniform soft clamping force to prevent indentation damage on delicate tiny workpieces.
  3. Integrated Standard T-slot Mounting Base
    Built-in bottom T-shaped mounting groove, universally compatible with worktables of all mainstream surface grinders, EDM equipment and small CNC engraving machines, no extra conversion plate needed for rapid fixture disassembly and installation.
  4. Complete Multi-size Series Covering Full Precision Machining Scenarios
    Covers micro tiny part processing (QGG25/33/38), standard precision mold processing (QGG50~QGG100), and large mold blank clamping (QGG125/QGG150/QGG200). Models with suffix "A" are extended opening versions with longer maximum jaw stroke for oversized miniature precision blanks.
  5. Detachable Hardened Precision Ground Jaws
    Clamping jaws are fully quenched and mirror ground; customized soft copper/aluminum protective jaws can be replaced to clamp coated, thin-wall and fragile precision workpieces without surface scratching.
