Component Specifications

Definition
The gripping surface is a critical functional area on clamping jaws that interfaces directly with workpieces to provide secure, non-slip holding during machining, assembly, or testing operations. It is engineered to maximize friction and distribute clamping forces evenly while minimizing workpiece deformation or surface damage.
Working Principle
The gripping surface operates on mechanical friction principles, where surface texture, material properties, and geometry create sufficient static friction to counteract machining forces. The surface may incorporate patterns, coatings, or compliant materials that conform to workpiece irregularities while maintaining consistent clamping pressure across the contact area.
Materials
Typically made from hardened tool steel (AISI D2, A2), carbide inserts, or engineered polymers with high wear resistance. Surface treatments include titanium nitride (TiN) coating, diamond-like carbon (DLC) coating, or specialized rubber/polyurethane overlays for delicate workpieces.
Technical Parameters
  • Wear Resistance Minimum 100,000 cycles
  • Surface Hardness 58-62 HRC (hardened steel)
  • Surface Roughness Ra 0.8-3.2 μm
  • Temperature Range -20°C to 150°C
  • Maximum Clamping Force Up to 5000 N per jaw
Standards
ISO 12164, DIN 69893, ISO 26623
