HEADMAN CK7130B CNC LATHES

Technical Description

This CNC chuck features a **0.236-inch chuck size** designed to securely hold bars up to **1.417 inches in diameter**, supporting precision bar machining. It has a **swing capacity of 13.386 inches**, accommodating workpiece rotation on lathes with sufficient clearance for larger diameters. The maximum **machining length is 13.780 inches**, permitting extended workpiece processing within the chuck. Constructed for CNC control, the chuck offers precise, repeatable gripping suited for automated machining processes. Its design optimizes rigid clamping and high repeatability necessary for high-speed CNC turning applications. The chuck’s through-bore size allows bar feed-through, enhancing versatility for continuous bar work. Typically, such chucks integrate hardened alloy steel with ground sliding surfaces to ensure long service life, along with lubrication provisions for sustained gripping force. A self-locking wedge mechanism likely maintains clamping power under cutting loads, preventing slip and enhancing operator safety. The chuck is engineered for hydraulic or pneumatic rear actuation through the machine spindle drawbar, ensuring consistent, adjustable clamping force aligned with CNC operation requirements. This design supports stable holding even at high spindle speeds, essential for precision machining with minimal run-out and vibration. Suitable for various jaw configurations depending on workpiece shape, the system balances durability, accuracy, and ease of jaw replacement, making it ideal for demanding CNC lathe applications.
