Component Specifications

Definition
A fixed jaw is the stationary component in a vise or clamping system that remains immobile during operation, providing a stable reference surface against which workpieces are secured. It typically features precision-ground surfaces and mounting interfaces to ensure accurate alignment and repeatable positioning in industrial applications.
Working Principle
The fixed jaw operates by providing a rigid, stationary reference surface against which the movable jaw applies clamping force. It remains anchored to the machine base or vise body, creating a stable datum for workpiece positioning while resisting deformation under clamping loads through its structural design and material properties.
Materials
Typically manufactured from hardened tool steel (AISI D2, A2), alloy steel (4140, 4340), or carbide-tipped variants for wear resistance. Surface hardness ranges from 58-62 HRC for standard applications, with specialized coatings (TiN, TiCN) applied for enhanced durability in high-volume production.
Technical Parameters
  • Width Range 50-300 mm
  • Height Range 25-150 mm
  • Mounting Type T-slot, bolt-on, or integrated
  • Surface Flatness 0.01-0.05 mm
  • Parallelism to Base 0.02 mm maximum
  • Clamping Force Capacity 500-5000 N
Standards
ISO 10889, DIN 6343

Frequently Asked Questions

What is the difference between fixed and movable jaws in a vise system?

The fixed jaw remains stationary and provides the reference surface, while the movable jaw applies clamping force. This design ensures consistent workpiece positioning and prevents shifting during machining operations.

Can fixed jaws be replaced or upgraded?

Yes, most fixed jaws are designed as replaceable components. Upgrades to harder materials or specialized coatings can extend service life in demanding applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
