Clamping Jaws / Collet: Grip Range 1-100 mm diameter

Q: What is the difference between clamping jaws and collets for lens holding?

Clamping jaws typically use multiple discrete contact points and are adjustable for different lens sizes, while collets provide continuous 360-degree contact through radial compression, offering better centering accuracy but with less size flexibility.

Q: How do I prevent lens damage during clamping?

Use non-marring insert materials, control clamping force precisely, ensure proper surface contact distribution, and implement force-limiting mechanisms to prevent over-tightening.

Component Specifications

Definition

Clamping jaws or collets are precision-engineered components used in lens holding fixtures to securely grip and position optical lenses during machining, polishing, or assembly processes. These components ensure accurate centering, minimal deformation, and repeatable positioning for high-precision optical manufacturing applications.

Working Principle

These components operate on mechanical clamping principles, typically using radial compression (collets) or jaw-based gripping mechanisms. They apply uniform pressure around the lens periphery to secure it without causing stress concentrations or optical distortion, often incorporating self-centering features for precise alignment.

Materials

Typically made from hardened tool steel (AISI D2, A2), stainless steel (17-4PH, 316), or carbide for wear resistance. May include non-marring inserts (urethane, Delrin) for delicate lens surfaces. Surface treatments include nitriding, chrome plating, or TiN coating for durability.
