CNC Vise Manufacturer | Precision Workholding Solutions

What Is a CNC Vise?

A CNC vise is a precision workholding device designed to securely clamp workpieces on CNC machining centers. Unlike manual bench vises, CNC vises are engineered for repeatable positioning accuracy of ±0.005 mm or better, enabling unattended production runs where every part must be identical to the last. The vise body is typically machined from hardened alloy steel or ductile iron, with ground reference surfaces that ensure the workpiece sits in exactly the same position every cycle.

In modern CNC manufacturing, the vise is not just a clamp — it is a critical link in the precision chain. A vise that flexes, shifts, or wears inconsistently will transmit errors directly into the finished part, no matter how accurate the machine tool itself may be. This is why choosing the right CNC vise manufacturer matters: the quality of your workholding determines the quality of your output.

Types of CNC Vises JIYAN Manufactures

As a specialized CNC vise manufacturer, JIYAN produces a complete range of workholding vises engineered for different machining applications. Each type is designed to solve specific clamping challenges:

Precision CNC Machine Vises

Our standard precision vises are the workhorse of machine shops worldwide. Featuring hardened and ground guide surfaces, these vises deliver clamping forces up to 25 kN with repeatability of ±0.005 mm. They are available in sizes from 80 mm to 400 mm jaw width, suitable for everything from small component machining to large mold making. The single-screw mechanism uses a thrust bearing design that ensures parallel clamping pressure across the entire jaw face, eliminating the upward lift that plagues lower-quality vises.

Self-Centering Vises

Self-centering vises use a synchronized dual-lead-screw mechanism that moves both jaws simultaneously toward the center, automatically aligning the workpiece on the vise centerline. This is critical for applications where symmetrical machining is required — such as boring, drilling, or milling operations on cylindrical or hexagonal stock. JIYAN's self-centering vises achieve centering accuracy of ±0.02 mm, making them ideal for high-precision production environments. Learn more about self-centering vises →

Zero-Point Clamping Systems

Zero-point clamping is the foundation of modern pallet-based machining. Instead of bolting a fixture directly to the table, you mount it on a zero-point base plate that locks into a receiver with a single turn of a key — or automatically via pneumatic or hydraulic actuation. This allows operators to swap entire setups in under 30 seconds, with positioning repeatability of ±0.002 mm. For shops running multiple jobs on the same machine, zero-point systems can cut setup time by 80% or more.

5-Axis Workholding Vises

5-axis machining demands workholding that provides maximum access to the part from all sides. JIYAN's 5-axis vises feature low-profile bodies, narrow jaw designs, and elevated tower configurations that lift the workpiece above the table surface — giving the cutting tool clear access to five faces of the part in a single setup.

Why Choose JIYAN as Your CNC Vise Manufacturer?

Manufacturing Precision

Every JIYAN vise is manufactured in our ISO 9001 certified facility in Dongguan, China. The production process includes CNC machining of all critical surfaces, heat treatment to 55-60 HRC for wear components, and precision grinding of guide ways to within 0.005 mm flatness. Each unit undergoes 100% CMM (Coordinate Measuring Machine) inspection before shipment, with a detailed inspection report included.

Material Quality

We use only certified materials: ductile iron (GGG40/GGG50) for vise bodies, alloy steel (42CrMo/40Cr) for screws and jaws, and bearing-grade bronze for thrust surfaces. Material certificates are available for every production batch, ensuring full traceability from raw stock to finished product.

Global Supply Capability

JIYAN serves over 800 machine shops across 40+ countries. We maintain stock of standard models for fast shipment, and our engineering team can deliver custom fixture designs within 3 business days. DDP (Delivered Duty Paid) shipping is available to the United States, European Union, and Asia, meaning you receive your workholding with all import duties and customs handled.

Engineering Support

Unlike distributors who simply resell catalog products, JIYAN is a manufacturer with in-house engineering capabilities. When a standard vise doesn't fit your application, our engineers design a custom solution — from modified jaw profiles to entirely new fixture configurations. Every custom project starts with a 3D CAD proposal, and we iterate until you approve the design before any metal is cut.

CNC Vise Specifications and Selection Guide

Choosing the right CNC vise depends on several factors. Here is a practical guide to help you select the correct workholding for your application:

Jaw Width and Opening Capacity

The jaw width determines the maximum workpiece size the vise can hold. For general-purpose machining, a 125 mm (5-inch) or 160 mm (6-inch) vise covers most applications. For larger parts, 200 mm and 250 mm vises provide the necessary capacity. Keep in mind that a larger vise is not always better — a vise that is too large for the part can introduce clamping instability.

Clamping Force

Clamping force is the pressure the vise applies to hold the workpiece. Standard manual CNC vises typically deliver 15-25 kN of clamping force. Hydraulic and pneumatic vises can provide 30-50 kN. The required force depends on the material being machined, the cutting forces involved, and the surface area of contact between the jaws and the workpiece.

Repeatability

Repeatability is the most critical specification for production environments. It defines how precisely the vise returns the workpiece to the same position after each clamping cycle. JIYAN vises achieve ±0.005 mm repeatability as standard, with zero-point systems reaching ±0.002 mm. For context, a human hair is approximately 0.07 mm in diameter — our vises hold tolerances 14 times tighter.

Mounting Compatibility

All JIYAN CNC vises use standard bolt patterns compatible with major machine tool tables, including Haas, DMG Mori, Mazak, Okuma, Fanuc, and Makino. Custom mounting plates are available for non-standard table configurations.

CNC Vise Maintenance and Longevity

A quality CNC vise is an investment that should last decades with proper maintenance. JIYAN vises are designed for serviceability — all wear components (jaws, screws, thrust bearings) are replaceable. Recommended maintenance includes:

• Clean and lubricate the lead screw and thrust bearing monthly
• Inspect jaw surfaces for wear or damage every 500 clamping cycles
• Check vise alignment on the machine table quarterly using a dial indicator
• Store vises in a dry environment to prevent corrosion on ground surfaces

With proper care, a JIYAN vise will maintain its original accuracy for 10+ years in production use. All vises come with a 2-year warranty covering manufacturing defects.

Frequently Asked Questions

What makes JIYAN different from other CNC vise manufacturers?

JIYAN is a manufacturer, not a distributor. This means we control every aspect of production — from material selection to final inspection — and can customize any product to your exact requirements. We also provide engineering support that resellers cannot match.

Do you offer custom vise designs?

Yes. Custom fixture design is a core part of our business. Send us your part drawing and we will design a dedicated workholding solution, typically delivering a 3D proposal within 3 business days.

What is the minimum order quantity?

There is no minimum order for standard catalog products. Custom designs typically require a minimum of 5 units to justify tooling costs, but we accommodate smaller quantities for prototyping.

How long does shipping take?

Standard products ship within 2 weeks. DDP shipping to the US takes 7-14 days by sea, or 3-5 days by air. We provide tracking numbers and handle all customs documentation.

Do your vises come with a warranty?

Yes, all JIYAN vises include a 2-year warranty against manufacturing defects. Wear components (jaws, screws) are covered for 1 year under normal use.
