Jergens Bock Modular Workholding | 20" OAL | Repeatable +/- .0005" Accuracy

Jergens Bock Series 20" Quick-Change Workholding Device

Brand: Jergens, Inc. (Bock Brand) | Length: 20" | System: Modular CNC Workholding

Professional Overview

The Jergens Bock Series is a high-performance, American-made workholding solution engineered to maximize spindle uptime in CNC milling environments. This 20-inch overall length unit features a modular "Quick-Change" design that allows for rapid setup transitions and repeatable part locating. Built with hardened and ground steel components, this device provides the extreme rigidity required for high-speed machining and heavy material removal.

Technical Specifications

• Overall Length: 20.00".
• Width: 6.00".
• Distance Between Clamps: 12.00".
• Repeatability: Precision-ground surfaces for consistent +/- .0005" accuracy.
• Construction: Hardened alloy steel ways and high-strength lead screw.
• Compatibility: Designed to interface with Jergens Ball Lock® or standard T-slot tables.

Key Performance Features

• Bock Quick-Change Technology: This system is specifically designed to reduce setup times from minutes to seconds. Its modular nature allows for quick swaps of top-tooling, making it ideal for high-mix/low-volume production.
• Chip-Resistant Design: Features a fully enclosed or flow-through base that prevents swarf and coolant debris from fouling the clamping mechanism, ensuring smooth operation in heavy production cycles.
• Maximum Work Envelope: The 20-inch footprint provides a generous capacity for mounting multiple small workpieces or larger single components, effectively expanding your machine's table capabilities.
• Industry-Standard Durability: Jergens Bock units are renowned for their long service life in demanding shop environments; the hardened surfaces resist "peening" and wear even under high clamping loads.
