Product Overview

In modern CNC manufacturing, machine downtime during part changeovers is lost profit. Traditional vises require unbolting and re-bolting jaws, which is slow and prone to chip interference. The GT Precision Modular Vise with a Quick Change Jaw System eliminates this bottleneck. By utilizing a precision dovetail or wedge-lock mechanism, jaws slide in and lock securely in seconds with a simple turn of a wrench. Combined with the vise's modular, perfectly square body, this system allows for incredibly fast, repeatable setups, making it the ultimate choice for high-mix, low-volume production and complex multi-part fixtures.

Key Features & Advantages

• Rapid Quick-Change Jaws: Swap between serrated jaws for roughing, smooth jaws for finishing, or custom-machined soft jaws for complex profiles in under 10 seconds. No bolts to lose, and no chip traps in counterbores.

• True Modular Design: The vise body is precision-ground to exact dimensions on all sides. This allows multiple GT vises to be mounted side-by-side or end-to-end on a machine table or tombstone, perfectly aligned for clamping long extrusions or multiple small parts simultaneously.

• Anti-Lift Mechanism: The movable jaw features a specialized pull-down mechanism (often a spherical segment or angled wedge). As clamping force is applied, the jaw is actively pulled down against the bed, completely eliminating workpiece lift and ensuring perfect parallelism.

• Extreme Precision & Durability: Manufactured from premium alloy steel, case-hardened to HRC 58-62, and precision-ground. The vise delivers a parallelism and squareness accuracy of 0.005mm/100mm (0.0002"), maintaining its geometry even under immense clamping pressure.

• High Clamping Force: The robust lead screw and thrust bearing design translates minimal torque into massive, rigid holding power, preventing part movement during aggressive heavy milling operations.

Frequently Asked Questions (FAQ) - Selection Guide

Q1: How exactly does the quick-change jaw system work?

A: Instead of bolting through the face of the jaw, our quick-change system uses a precision-machined interface (like a dovetail or a sliding wedge) on the master jaw carrier. You simply slide the replacement jaw onto the carrier and tighten a locking screw located on the top or side. This securely wedges the jaw into place in seconds, with perfect repeatability.

Q2: Can I mount these vises on their side?

A:Yes. The "modular" aspect of the GT vise means that the base, sides, and ends are all precision-ground to be perfectly square and parallel to each other. You can mount the vise flat on its base, upright on its side, or even vertically on its end, making it incredibly versatile for 4-axis and 5-axis machining setups.

Q3: Are the quick-change jaws proprietary, or can I make my own soft jaws?

A: While the locking interface is specific to the quick-change system, we offer blank, machinable soft jaws (in steel or aluminum) that feature the correct mounting interface. You can purchase these blanks and machine them in-house to perfectly match the complex contours of your specific workpieces.

Q4: How do I align multiple GT vises on my machine table?

A: Because the vises are precision-ground to identical dimensions, you can easily align them. The most common method is to place precision locating keys (T-slot nuts) into the keyways on the bottom of the vises, which align them with the machine table's T-slots. You then use a dial indicator to sweep the fixed jaws to ensure they are perfectly parallel to the machine's X-axis before final tightening.
