QKG Series Ball Bearing Quick-Slide All-Steel Ultra Precision Grinding & EDM Tool Maker Vice

Fully hardened monolithic alloy steel quick-action precision vise equipped with built-in ball bearing sliding rails. The QKG product line covers micro miniature to large mold specifications, with A/B suffix extended-opening variants for extra-long workpieces. All datum contact surfaces are mirror hard-ground to micron-level geometric tolerances. Unlike traditional screw-feed vises, it adopts ball linear slides for fast, smooth jaw positioning without repeated lead screw rotation. It is specially matched with surface grinders, wire EDM, sinker EDM and micro engraving CNC machines, serving as high-precision fixture for mold inserts, gauge pins, thin fragile precision hardware and tiny optical components.

Description

This QKG quick-slide precision vise optimizes the positioning efficiency of the QGG screw-driven precision vise by integrating internal ball bearing linear sliding structures, drastically shortening fixture setup time while retaining ultra-high machining accuracy for mold precision processing. The whole unit is forged from a single alloy steel blank, subjected to full quenching and cryogenic stabilization aging to eliminate internal material stress and avoid permanent deformation under long-term clamping load. All sliding rails, jaw clamping planes and bottom mounting datum surfaces are mirror precision ground to guarantee ultra-low flatness, parallelism and perpendicularity.
  1. Built-in Ball Bearing Linear Quick Slide Mechanism
    Multiple wear-resistant steel ball bearings are embedded in the sliding base. The movable jaw can slide freely and smoothly for rough positioning without rotating a lead screw. After quick alignment, a single central hex locking bolt firmly secures the jaw, cutting workpiece clamping time by over 60% compared to conventional screw-type precision vises.
  2. Monolithic Fully Hardened Alloy Steel High-Rigidity Body
    Integral solid steel blank forming, overall quenched to HRC58-62 high hardness with cryogenic aging treatment to lock permanent dimensional stability. Full-stroke flatness and parallelism tolerance are controlled within 0.003mm, fully meeting the strict precision standards of surface grinding and electrical discharge machining.
  3. Single Central Hexagon Locking Bolt
    The oblique central hex locking bolt outputs balanced vertical and horizontal clamping force to prevent workpiece tilting during tightening. The concave anti-slip bolt head fits standard hex wrenches for convenient field operation.
  4. Universal Long T-slot Mounting Base
    A long through T-shaped mounting groove is reserved at the bottom, compatible with worktables of all mainstream surface grinders, EDM equipment and miniature CNC engraving machines. No conversion plate is required for rapid installation and disassembly.
  5. Complete Multi-size Series with Tiered Extended Opening Versions
    Covers micro tiny component processing (QKG25/36/38), standard precision mold processing (QKG50~QKG125), and large mold blank clamping (QKG150/QKG200). Models with suffix A/B are extended opening variants; B-type provides a longer maximum jaw stroke than A-type for oversized miniature precision blanks.
  6. Replaceable Hardened Precision Ground Jaws
    Clamping jaws are fully quenched and mirror ground. Custom copper/aluminum soft protective jaws can be swapped to clamp coated, thin-wall and fragile precision parts without scratching finished surfaces.

Model Naming Rule

Format: QKG[Jaw Width][A/B Extended Stroke Suffix]
Example: QKG150B
  • QKG: Exclusive series code for ball bearing quick-action precision grinding vise
  • Numerical value: Jaw width dimension (unit: mm)
  • Suffix A/B: Tiered extended opening stroke variants; B version features longer Smax opening travel than A version
