Precision JA Ultra-Precision Diaphragm Chuck Tooling System

Engineered for high-accuracy turning and grinding applications, the JA8-150 chuck features a durable spring collet design with hardened steel construction for extended tool life. The diaphragm mechanism ensures consistent clamping force, minimizing runout below 0.003mm for superior surface finishes.

Ideal for CNC machining, optical lens production, and medical device manufacturing, its thermal-stabilized alloy body resists deformation under heavy loads. The self-centering JA8 collet accepts workpieces from 0.5-8mm with micron-level repeatability.

Direct-from-factory pricing eliminates middleman costs, offering industrial-grade precision at wholesale rates. Compatible with Haas, DMG Mori, and other major lathe brands—bulk discounts available for OEM purchases.
