Component Specifications

Definition
A mounting shank is a critical interface component in tactile probe systems used for dimensional metrology. It serves as the mechanical and electrical connection between the probe head/stylus assembly and the measuring machine's quill or adapter. The shank ensures precise alignment, repeatable mounting, and reliable signal transmission for touch-trigger or scanning probes during coordinate measurement operations.
Working Principle
The mounting shank provides a rigid, accurately machined interface that maintains the probe's geometric relationship with the measuring machine's coordinate system. It transmits trigger signals or measurement data through electrical contacts while ensuring mechanical stability during probing cycles. Kinematic mounting principles are often employed to achieve repeatable positioning within micron-level tolerances.
Materials
High-strength stainless steel (typically 17-4PH or 440C), hardened tool steel, or ceramic for wear resistance and dimensional stability. Surface treatments may include hard chrome plating or nitride coatings for enhanced durability.
Technical Parameters
  • Length 20-100mm (varies by application)
  • Weight 5-50g (depending on size and material)
  • Taper Angle 30° or 45° (common for kinematic mounts)
  • Thread Type M4, M5, M6, or proprietary threads
  • Shank Diameter 3mm, 4mm, 6mm, 8mm (standard metric sizes)
  • Electrical Contacts 3-6 pins (for signal transmission)
  • Maximum Load Capacity 50-500N (depends on design)
Standards
ISO 10360, ISO 15530, DIN 2257, VDI/VDE 2617

Frequently Asked Questions

What is the purpose of a mounting shank in tactile probe systems?

The mounting shank provides the physical and electrical interface between the probe stylus assembly and the measuring machine, ensuring precise alignment, repeatable mounting, and reliable signal transmission during measurement operations.

How do I select the correct mounting shank for my CMM probe?

Selection depends on the probe model, machine interface type, required accuracy, and application. Key factors include shank diameter, thread specification, electrical contact configuration, and material compatibility with your measurement environment.

Can mounting shanks be interchanged between different probe brands?

While some standardized shanks (like M4 or M6 threads) may be compatible across brands, most systems use proprietary interfaces. Always verify compatibility with both probe and machine specifications before interchange.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
