[Product Overview]

The QGG Series Vise (Manual Screw Type) is the industry standard for tool and die makers. Unlike standard machine vises, the QGG vise is completely solid and precision-ground on all working surfaces. This allows the vise itself to be turned on its side or stood on its end while holding the workpiece, making it incredibly easy to machine multiple faces of a part perfectly square to one another without unclamping. The smooth manual screw mechanism provides a strong, reliable grip for small to medium-sized precision components.

[Key Features & Advantages]

• Extreme Accuracy: Parallelism and squareness are strictly controlled to within 0.005mm per 100mm (0.0002"), ensuring your parts meet the tightest tolerances.

• Premium Hardened Steel: Constructed from high-quality 20CrMnTi or SK2 steel. It undergoes vacuum heat treatment and sub-zero processing to reach a uniform hardness of HRC 58-62, preventing distortion over time and resisting wear.

• Multi-Sided Operation: Precision ground on the bottom, both sides, and the end. You can flip the vise in any direction on a magnetic chuck or machine table.

• V-Groove Jaw Design: The movable jaw features horizontal and vertical V-grooves, allowing for the secure clamping of round workpieces (like pins or small shafts) as well as flat stock.

• Smooth Screw Mechanism: The fully enclosed precision lead screw protects against grinding dust and chips, ensuring smooth operation and consistent clamping force.

Frequently Asked Questions (FAQ) - Selection Guide

Q1: What is the difference between the QGG and QKG precision vises?

A:

• QGG (Screw Type): Uses a threaded lead screw and a crank handle to open/close the jaws. It offers continuous adjustment and is great for general precision work.

• QKG (Pin Type / Toolmaker's Vise): Uses a quick-action pin and a locking screw. It is faster to adjust for different sized parts and has a slightly lower profile, but lacks the continuous screw feed.

Q2: Can this vise be used for heavy CNC milling?

A: No. The QGG vise is designed for grinding, EDM, inspection, and light milling/drilling. For heavy-duty CNC milling, we highly recommend our GT Series Precision Modular Vises or Hydraulic Machine Vises, which are built to withstand heavy cutting forces.

Q3: How do I mount the QGG vise to my machine?

A: The most common method is placing it directly onto a magnetic chuck on a surface grinder. For milling machines, it can be clamped to the T-slot table using standard toe clamps (strap clamps) gripping the slots on the sides of the vise base.

Q4: Is it rust-proof?

A: The vise is made of hardened alloy steel, not stainless steel, to maintain its magnetic properties and hardness. It is coated with anti-rust oil before shipping. We recommend wiping it clean and applying a light coat of rust-preventative oil after each use, especially when using water-based coolants.
