High-Precision Engineering
Dual-jaw synchronous linkage structure ensures equal clamping displacement on both sides, automatically centering parts to the fixture central axis without manual adjustment. Replaceable bronze wear pads protect the Cr12MoV jaw substrate from friction erosion, cutting long-term maintenance costs. Standard T-slot base mounting holes enable fast installation on CNC machine tables, grinders and mold assembly platforms. Jaw profiles can be swapped to match square, rectangular or custom-shaped workpiece blanks.
High-Wear Resistant Cr12MoV Steel Construction
Constructed from premium Cr12MoV high-chromium cold work die steel, this fixture offers robust mechanical performance:
- High compressive hardness and outstanding abrasion resistance for thousands of repeated clamping cycles
- Excellent impact toughness to resist chipping under heavy clamping and cutting loads
- Minimal permanent deformation under sustained clamping pressure and machining heat
- Stable dimensional stability for long-batch mass production runs Perfect for heavy-duty metal blank machining, mold component pre-processing and automated precision part assembly lines.
Modular Customizable Structure
Fully configurable fixture parameters to match production demands:
- Custom jaw opening width, clamping stroke and contact face profile
- Interchangeable soft/hard jaw inserts for aluminum, steel, copper or alloy workpieces
- Optional ion nitriding hardening for bare steel jaw surfaces
- Extended base plate sizes for larger symmetrical workpiece batches
Key Features & Advantages
- Automatic Symmetric Centering: Bidirectional synchronized jaws eliminate alignment errors for symmetrical part batches.
- Low-Friction Durability: Bronze self-lubricating pads reduce sliding wear and prevent jaw seizing.
- Cost-Effective Maintenance: Only wear pads require replacement, preserving the expensive Cr12MoV base fixture frame.
- Universal Machine Compatibility: T-slot base fits most standard CNC lathes, milling machines and mold workbenches.

Applications
Automotive
Used for clamping small symmetrical automotive valve fittings, transmission pin blanks and sensor housing castings during turning and milling; high-hardness Cr12MoV handles heavy stock removal for high-strength auto metal components.
Consumer Electronics
Applied for precision positioning of miniature motor housings, connector base blocks and thin symmetrical electronic hardware; synchronous centering guarantees tight dimensional tolerances for compact electronic assemblies.
Medical
Suitable for clamping stainless steel surgical tool blanks and symmetrical medical fitting components; controlled low-deformation clamping avoids scratching polished medical-grade workpiece surfaces.
Automation & Mold Machining
Deployed as standardized workholding fixtures on automated CNC production lines and mold workshops, reliable repeat clamping speeds up batch processing of mold inserts, core pins and symmetrical mold blocks.
