High-Precision Workholding for Submerged & Rust-Sensitive Environments
The Pro-Series 3901-2766 is a professional-grade EDM vise designed for machine shops that prioritize accuracy and tool longevity. Built from high-quality, corrosion-resistant stainless steel, this vise is specifically intended for use in environments where water or dielectric fluid would compromise standard carbon steel tooling. Whether you are performing Wire EDM operations or fine-surface grinding, this vise ensures your workpiece remains secure and perfectly aligned.
Advanced Geometry & Build Quality
Precision is the hallmark of this tool. It is hardened to HRC 48-55 and ground to exacting standards, offering a squareness tolerance of .0002″ and parallelism of .00012″. The integrated 45° lockdown mechanism provides a downward force during clamping, effectively preventing “workpiece lift” or floating—a common challenge when machining thin or delicate parts.
Shop-Floor Benefits
- Corrosion Resistance: Fully stainless steel construction prevents oxidation in submerged EDM tanks or wet grinding setups.
- Process Stability: High hardness (HRC 48-55) ensures the vise maintains its accuracy over years of heavy use without losing flatness.
- Versatile Clamping: A generous 0-100mm (approx. 4″) capacity makes it suitable for a wide range of small-part manufacturing.
- Eliminate Float: The 45° angular pull-down design guarantees the part stays seated against the base for superior Z-axis accuracy.
Recommended Applications
- Wire EDM: Ideal for submerged or flushed applications requiring non-rusting workholding.
- Precision Grinding: Perfect for small toolroom grinding where coolant exposure is constant.
- Mold & Die: Essential for finishing small cores and cavities with extreme precision.
- Medical & Aerospace: Suitable for small, thin-walled components requiring high geometric tolerances.
