Product Overview

When machining large castings, long extrusions, or oversized plates, standard CNC vises are often too short, and custom fixturing can be prohibitively expensive and time-consuming. The ZQ84 Precision Modular Vise (Two-Piece Vise) provides a highly flexible and cost-effective solution. By separating the fixed jaw and the movable clamping jaw into two independent units, the maximum opening capacity is limited only by the size of your machine's T-slot table. You simply bolt the fixed jaw at one end of the workpiece and the movable jaw at the other. The movable section features a robust lead screw mechanism that applies heavy clamping pressure directly against the fixed jaw, securing massive parts rigidly for aggressive milling and drilling.

Key Features & Advantages

• Unlimited Clamping Capacity: The independent two-piece design allows the jaws to be positioned at any distance apart on the machine table. This makes it the perfect solution for holding extra-long shafts, large plates, or bulky castings that exceed the capacity of traditional single-body vises.

• Heavy-Duty Construction: Manufactured from premium alloy steel and case-hardened. The massive, thick-walled design of both the fixed and movable sections absorbs heavy machining vibrations, preventing chatter during high-material-removal operations.

• Precision Ground Surfaces: All critical mating surfaces, including the jaw faces and the base, are precision-ground to ensure excellent parallelism and squareness, keeping your large workpieces accurately aligned with the machine axes.

• High Clamping Force: The movable jaw utilizes a heavy-duty lead screw and thrust bearing assembly, generating immense clamping pressure to securely hold large, heavy parts without slipping.

• Flexible Setup Options: Multiple ZQ84 sets can be used simultaneously. For extremely long or wide parts, you can use two fixed jaws and two movable jaws in parallel to provide even clamping pressure across the entire workpiece.

Frequently Asked Questions (FAQ) - Selection Guide

Q1: How do I ensure the two pieces of the ZQ84 vise are aligned perfectly straight?

A: Both the fixed and movable jaw sections feature precision-machined keyways on their bottom surfaces. You install standard T-slot alignment keys into these keyways, which then drop into the T-slots of your machine table. This guarantees that both jaws are perfectly parallel to each other and aligned with the machine's X or Y axis.

Q2: What is the maximum opening capacity of a ZQ84 vise?

A: Because the two sections are independent, the maximum opening capacity is technically unlimited. It is restricted only by the length of your machine's worktable and the distance between the T-slots you use for mounting.

Q3: Can I use the ZQ84 vise for small parts?

A: While you can place the two jaws close together to hold small parts, it is generally not recommended as the primary use. Standard single-body vises (like GT or Kurt-style vises) are faster to set up and more practical for small components. The ZQ84 is specifically engineered to solve the problem of holding oversized or extra-long workpieces.

Q4: Does the ZQ84 have a "pull-down" feature to prevent part lift?

A: The standard ZQ84 is a heavy-duty clamping vise and typically does not feature the active pull-down wedge mechanism found in high-precision GT modular vises. When clamping very large parts, the sheer weight of the workpiece and the massive clamping force usually keep the part seated. However, operators often use a dead-blow hammer to ensure the part is firmly seated on parallels before final tightening.
