Product Specifications

Technical details and manufacturing context for Clamping Jaws / Vise

Definition
Clamping jaws or vises are essential components within a Profile Clamping System designed to firmly hold and secure profiles, workpieces, or materials during machining, assembly, or processing operations. They provide precise positioning and prevent movement through mechanical force application.
Working Principle
Operates by applying mechanical force through screw mechanisms, hydraulic pressure, or pneumatic systems to move opposing jaw surfaces toward each other, creating friction and pressure that securely grips the workpiece between them.
Common Materials
Hardened Steel, Tool Steel, Aluminum Alloy
Technical Parameters
  • Maximum jaw opening width and clamping force capacity (mm) Per Request
Components / BOM
  • Fixed Jaw Part
    Stationary clamping surface that provides reference point
    Material: Hardened Steel
  • Movable Jaw Part
    Adjustable clamping surface that applies pressure
    Material: Hardened Steel
  • Lead Screw Part
    Mechanism that moves the movable jaw via rotational force
    Material: Alloy Steel
  • Jaw Inserts Part
    Replaceable contact surfaces with different profiles or materials

Downstream Applications
Specialized Tooling

Application Fit & Sizing Matrix

Operational Limits
pressure: Max clamping force: 5-50 kN depending on size and design
other spec: Surface hardness: 45-65 HRC, Jaw opening range: 50-300 mm typical
temperature: -20°C to +150°C (standard steel), up to +500°C with special alloys
Media Compatibility
✓ Steel profiles and workpieces ✓ Aluminum extrusions ✓ Plastic/composite materials
Unsuitable: Highly corrosive chemical environments without protective coatings
Sizing Data Required
  • Workpiece dimensions (width, height, length)
  • Required clamping force for application
  • Profile geometry and contact surface requirements

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Wear and loss of clamping force
Cause: Repeated clamping cycles causing abrasive wear on jaw surfaces, leading to reduced friction and insufficient grip strength
Fatigue cracking in jaw body
Cause: Cyclic loading from repeated clamping operations creating stress concentrations at jaw corners or mounting points, eventually leading to material fatigue and fracture
Maintenance Indicators
  • Visible scoring, galling, or excessive wear marks on jaw contact surfaces
  • Audible clicking or slipping sounds during clamping operations indicating loss of grip
Engineering Tips
  • Implement regular jaw surface inspection and cleaning protocols to remove debris that accelerates abrasive wear
  • Apply proper lubrication to jaw sliding mechanisms and ensure even pressure distribution during clamping operations

Compliance & Manufacturing Standards

Reference Standards
ISO 9001:2015 - Quality Management Systems ANSI B5.8-1972 - Machine Vises DIN 6319 - Machine Vises
Manufacturing Precision

Frequently Asked Questions

What materials are best for clamping jaws in heavy-duty applications?

For heavy-duty applications, hardened steel or tool steel clamping jaws are recommended due to their superior strength, wear resistance, and durability under high pressure and repetitive use.

How do I choose between fixed and movable jaws for my clamping system?

Fixed jaws provide stable, stationary support, while movable jaws adjust via a lead screw to accommodate different workpiece sizes. Most systems use both: a fixed jaw as an anchor and a movable jaw for clamping pressure.

Can aluminum alloy jaws be used in industrial machinery manufacturing?

Yes, aluminum alloy jaws are suitable for applications requiring lightweight components, corrosion resistance, or non-magnetic properties, though they offer lower strength than steel and are best for moderate clamping forces.

Can I contact factories directly on CNFX?

CNFX is an open directory, not a transaction platform. Each factory profile provides direct contact information and production details to help you initiate direct inquiries with Chinese suppliers.
