[Product Overview]

When standard toolmaker vises are simply too large for the job, the MINI Precision Vise steps in. It is essentially a scaled-down version of our professional QGG/QKG series, engineered to hold tiny, fragile parts securely. Whether you are grinding micro-pins, milling small medical device components, or setting up a complex wire EDM job, this miniature vise provides the rigid, square, and parallel reference surfaces you need for flawless execution.

[Key Features & Advantages]

• Ultra-Compact Footprint: Small enough to fit in the palm of your hand. It can be easily placed under a microscope for inspection or mounted inside a highly restricted CNC machining envelope.

• Exceptional Accuracy: Despite its small size, it is ground on all sides to guarantee parallelism and squareness within 0.005mm/100mm, ensuring your micro-parts meet strict tolerances.

• Material Options:

• Hardened Alloy Steel (SK2/20Cr): Vacuum treated to HRC 55-58 for standard precision grinding and milling.

• Stainless Steel (SUS440): Hardened to HRC 50-55, offering excellent corrosion resistance, making it ideal for submerged Wire EDM (WEDM) applications.

• Micro V-Groove Jaws: The movable jaw features precision-cut horizontal and vertical V-grooves, allowing for the secure clamping of tiny round parts, wires, and electrodes.

• Seamless Integration: The perfectly square body allows the mini vise to be clamped inside a larger standard vise (like a QGG50) to act as a precision sub-jaw for small parts.

Frequently Asked Questions (FAQ) - Selection Guide

Q1: How do I mount such a small vise to my machine?

A: There are several ways:

1. Place it directly on a fine-pole magnetic chuck (if using the alloy steel version).

2. Clamp the entire mini vise inside a larger, standard toolmaker's vise.

3. Use miniature strap clamps on a custom pallet or micro T-slot table.

Q2: Is this vise suitable for Wire EDM (WEDM)?

A: Yes, absolutely. If you are using it in a submerged water bath for Wire EDM, we highly recommend selecting our Stainless Steel version to prevent rust and maintain long-term accuracy.

Q3: Can it hold very thin or fragile parts without crushing them?

A: Yes. The manual screw mechanism allows for very fine control over the clamping pressure, making it ideal for holding delicate parts like watch components or thin electrodes without causing distortion.

Q4: What is the maximum jaw opening?

A: The maximum opening depends on the specific model size. For example, a 15mm jaw width vise typically has a maximum opening of around 15mm to 20mm. Please request our catalog for exact dimensions.
